View Full Version : Earthquake!

7.2 in Mexico City this morning.

Everything ok with you, Mario?

April 18th, 2014, 10:41 AM
Again? There's been a bunch of them lately.

April 18th, 2014, 03:34 PM
One of my FB friends was on the 3rd floor of a hotel in Mexico City when it hit. Minor damage to the room but they are OK.

April 18th, 2014, 03:43 PM
We're ok, thanks for asking.

It was a long one. Not particularly violent but it could have been bad had it been a little stronger or longer.

Again? There's been a bunch of them lately.

The whole week it seems.

I have no idea what I'm talking about, but from my purely amateur eye it seems like there have been a ton of 6+ quakes along the edges of the pacific plate. Very happy to hear you're okay, Mario.

April 18th, 2014, 09:42 PM
I'm also glad you're OK Mario.

How far were you from it? I thought you were further south.

April 18th, 2014, 09:43 PM
People get so worked up over 5's. Pffft. A 7 is some real shit though.

April 18th, 2014, 10:15 PM
It didn't feel that bad. I don't know if I can explain myself but it didn't have the violence of the combined motions. It was just a groovy sort of back and forth movements. It felt like the energy took a lot more time be released.

I'm in the city of Oaxaca (https://www.google.com/maps/place/Oaxaca/@17.1949053,-96.7531958,10z/data=!4m2!3m1!1s0x85c72249df26d9b1:0xac88a77657dff c3b), normally earthquakes originate underneath the Ometepec mountains (https://www.google.com/maps/place/Oaxaca/@16.5869979,-98.4394256,10z/data=!4m2!3m1!1s0x85c72249df26d9b1:0xac88a77657dff c3b), on the border of the states of Guerrero and Oaxaca, some 30 miles away from the coast. I guess I'm roughly some 200 miles from the epicenter.

April 18th, 2014, 10:18 PM
200 miles from a 7 is enough to feel it but not too bad.

April 18th, 2014, 10:18 PM
Mexican Seismic Institute has recorded 105 aftershocks so far.

April 19th, 2014, 05:50 AM
I'd forgotten that you moved. How's Oaxaca so far?

If the quakes get too big at least you can comfort yourself with delicious mole and a visit to Monte Alban.

April 19th, 2014, 04:16 PM
Glad you're ok, buddy! We don't get many earthquakes around here...when we do get one it's usually a 4-pointer or less. Feels like a cute little tremor. It's always something special because it's so infrequent.

April 20th, 2014, 04:51 AM
We are getting 3.0-4.0 earthquakes around here (Oklahoma) every few months. There are a lot of people saying its from the fracking going on in the oil fields. First one we felt, thought someone hit the house. The quakes come as a jolt and not the usual rolling style. Looked at the hanging lamps and they didn't even move. Not like the ones when I was in Ca where anything that hangs sways like a pendulum in a gale wind.

May 21st, 2014, 07:11 AM

I've never lived in Mexico City. I'm Oaxacan, born and raised. I moved to Villahermosa (http://farm5.staticflickr.com/4095/4790505329_41a1d8e8c6_z.jpg)at the beginning of the year, and there's no quakes here. And no prevention culture, either. Where I come from (and when I lived in Encinitas, notably) people would be really aware of their surroundings in the first seconds of a quake (or before, if there's an alarm system) and act accordingly. Once the OMG IT'S THE END OF THE WORLD!! initial panic goes by and everyone pretends they weren't the least bit scared, they start doing the things they've drilled for.

Out here, it's pretty scary, people are not prepared to deal with the psychology of a quake. They panic. We had* a 5.5 in the early morning today, and people are all freaked out at work. I don't know what they're gonna do in a couple of years when they start feeling the consequences of the fracking they've recently greenlighted.

*150 miles away

May 21st, 2014, 06:29 PM
Fracking causes tiny earthquakes, if any at all. Certainly less impact than the mine subsidence people dealt with in PA before fracking.

Fracking doesn't trigger earthquakes on active faults.

May 21st, 2014, 07:35 PM
That we know of...

May 21st, 2014, 11:43 PM
Everything has unintended consequences. We should be studying it, but if we wait for an energy source with zero drawbacks, we're all going to be sitting in the dark.

Luckily for Americans, most of the oil and gas reserves are in states with very little active seismicity - North Dakota and Pennsylvania, respectively. But any statements made about fracking increasing the chances of large earthquakes along active fault lines are pure speculation at this point. I just get very irritated when people spout off about fracking causing this and that when, at this point, there is zero science to back it up.

Honestly, I find it amusing that people are surprised that there might be small earthquakes in areas where fracking is occurring - I guess most of these people aren't used to living in areas where resource extraction is taking place. Small tremors were expected in the anthracite region where I grew up, and subsidence was really common. I guess I never really thought of them as "earthquakes"; they were just thought of as the effects of underground rockfalls.

May 22nd, 2014, 07:34 AM
I never said they would cause any major earthquakes. But from my experience here, the complete disregard for preparedness will cause some social unrest if they start getting continuous seismic activity, even if it lingers around 2.5 degrees.

You know there's major mass denial when people live in the deltas of the two biggest rivers in Mexico and they build within a hundred yards of them. And then complain about their losing their property to floods.

May 23rd, 2014, 04:53 AM
People have been building in questionable places for a long time. The side of a cliff, middle of a forest, on the beaches and then moan and groan when some a natural disaster comes along and destroys that house.

There are some around here that truly believe that the fracking is causing these quakes around here. Along with the quakes there are questions about fracking contaminating ground water. EPA is doing a study that may come out this year.

July 7th, 2014, 07:56 AM
7.1 at the Mexico/Guatemala border. I imagine that bumped you around a bit, Mario?

July 7th, 2014, 09:36 AM

I was getting the car out of the garage onto the street. No seismic alarm either, but that's because the triggers are on the Michoacán-Guerrero coast, not on the Chiapas side.

July 7th, 2014, 09:46 AM
Ha! Nice.

July 29th, 2014, 07:38 AM
Today's (http://earthquake.usgs.gov/earthquakes/eventpage/usb000ry8m#summary) was scary. It seemed to go on forever and it was quite noisy.

I am waiting on a buddy to respond to see if all is ok with him in San Fran.

August 24th, 2014, 10:14 PM

Didn't feel a thing here but I don't know if that's normal or just because I was asleep. I know on the east coast that a 6.0, even 500 miles away, would wake the dead.

August 24th, 2014, 11:30 PM
California's geology is different. Earthquakes don't transmit energy as far as they do on the east coast. This is largely due to the fact that we have earthquakes with some regularity. The earth's crust is less rigid here than the east. There's no way we're feeling a 6.0 from the bay area in SoCal. Maybe an 8 or so could go that far.

August 25th, 2014, 01:58 PM
My buddy in SF checked in with zero damage (or anything falling off the shelves fwiw).

August 25th, 2014, 05:19 PM
Makes sense.

November 13th, 2016, 07:36 AM
7.5 (ish, depending on source) in NZ overnight, a couple hundred km north of Christchurch on the South Island. Leon and Hannah (scoop) have both checked in on FB. Based on reddit posts, folks in Dunedin like SkylineObsession (and wifey) didn't feel it all that strongly. Peril's in Oz, now, right?

Pretty deep quake (23km) and appears to have ruptured towards the north, sparing CHCH. Looks like some damage in Wellington. I'm sure Nelson and other smaller South Island communities got hit, but haven't seen pics.

November 13th, 2016, 08:21 AM
That's a significant shake..., hope people there are alright...

November 13th, 2016, 09:39 AM
MOFO that was an interesting night.

I am amazed that my house survived that apparently undamaged. Just after midnight got quite the wake up call. I was braced in a doorway, with the whole damn place moving under me. One cat was running around the bedroom doing panic meows, the other cat who is in another room at night went under the spare bed and took quite a while to come out.

Tsunami warning was issued in the middle of the night, I don't think a lot eventuated from that. I slept through those warnings, as I went back to sleep (yay pills), but I am miles from the coast.

The Wellington central business district is apparently "closed" this morning, meaning workers have been told to stay home. I work out in the burbs so I am probably not effected.

November 13th, 2016, 09:42 AM
Looks like a couple of deaths reported so far.

Heart attack is one, collapsed house another.

November 13th, 2016, 10:06 AM

Interesting morning. Pretty much non stop aftershocks. Get a bit casual about it though, so I'm sitting in front of the TV, just ignoring that my house is wobbling every ten minutes or so.

Crunching the numbers, we're enjoying currently an average of 17 quakes an hour, over the last 24 hours .... and the quakes only started 18 hours ago.

Made for an interesting day at work. Particularly during one of the really big ones, that arrived as I was having a pee.

Braced against the walls and carried on. Not a drop was spilled.

November 13th, 2016, 09:58 PM
Yeah i was still up at midnight (playing FH3) and a while later before hitting the sack i noticed my compy was still on, so checked Facebook quickly and 'oh - there was an earthquake'?

Have relatives in Blenhiem, haven't heard from them but they may have changed cell numbers. And one of my uncles lives near Christchurch, but they are in Blenhiem at the mo - said "it hasn't stopped rocking all f...ing night". Obviously with the simply massive landslides along the coast, they'll have to take the long way home in a day or so.




November 13th, 2016, 10:02 PM

I'm still blown away seeing the sheer size of this slip - will take months to clear probably, and no guarantee that the rest of the hill would be stable anymore. :( Gutted, as that was a really nice road to drive on, and wifeys Skyline sounded great in the tunnels. :D.

According to the news, this earthquake-made dam burst open sometime today

November 13th, 2016, 10:09 PM


Poor moo cows. :( Hopefully they've been rescued - so random that it's just a tiny patch remaining.

Whoops, seems like a 10 or so story car park building in the central business district is now leaning ... they're making noises like "it's f**ked Jim, and is going to fall over".

Along with another building which is fortunately vacant currently anyway.

Apparently this shake has caused a whole lot more damage than expected.

November 17th, 2016, 01:59 AM
Yeah i'm quite surprised how they said that building would have to be demolished.

At the same time. i thought that their 'inspections' of buildings after the quakes was happening a little too quickly and not thoroughly enough. Seems i was kinda right in this thinking.

November 17th, 2016, 09:07 AM
The interesting thing about that car park building, is that after the earthquake a few years ago, that building was damaged and spent a year or so being strengthened before it re-opened.

Sooooooo, how exactly did that year worth of repairs and strengthening work out for you?

In the few brief articles I've read, it sounds like the foundation had some liquefaction issues. Doesn't matter how nice your building is if the foundation moves away underneath it. :|

Three foreign warships are expected to arrive off the Kaikoura coast this morning. They will be assisting with checks on smaller rural towns and delivering supplies. The international warships had been headed to the International Naval Review in Auckland. NZDF accepted offers from naval ships from the United States, Australia, Canada, Japan and Singapore to help with relief efforts. The USS Sampson, HMAS Darwin and HMCS Vancouver are now close to quake-hit areas, where their helicopters will help deliver supplies and evacuate people.

There's a bunch of really surprised aquatic life off the coast of Kaikoura (where the quake was centered), as the seabed has risen up to two meters in places.

November 29th, 2016, 09:28 AM
Apparently helicopters work by being so evil, that the ground repels them.

They're tearing down a few downtown Wellington buildings after the quake.

Seems that the frequency of the shake was really hard on 5-8 story buildings, but not too bad on low buildings, or buildings tall enough that they didn't have time to get a good sway going. So there are buildings that have been damaged by smacking into the building next to them.

One week after the big one.


I live on the grey dot between the orange and yellow, Mexico City is the inverted pentagon on the edges of lime. I'm Ok, but most people in the communities surrounding the lagoons near the epicenter are not. As the map shows, their lands were subjected to about 150 gal for over 3 minutes.

September 14th, 2017, 09:05 AM
Glad you're okay.

BTW, had to google up Gal... at first I was thinking Gallon! Just not very familiar with that unit and associating that with earthquakes. Not sure if it's a british unit thing? Anyway, 1G is 980 Gal... so I don't really have a good 'feel' for 150 Gal.

However, I do know 8.1 on the Richter scale is freaking scary! I don't even think LA can handle that kind of shaking very well for 3 minutes!

September 14th, 2017, 07:43 PM
Predicted peak ground acceleration (pga) for most dam sites near the San Andreas fault is 1g or higher, FWIW. Minimum pga that most California dams are designed to is typically 0.15g.

The USGS, et al, will be all over the records from this Mexican quake--the engineering community desperately needs good records for large subduction zone quakes.

September 15th, 2017, 09:42 AM
Do we really need to worry about peak accel for dams? Kinda like race car driver could survive more than 100G's in a crash, but probably can't last too long under a sustained 10G...

Anyway, regardless..., sounds like our dams may not hold up in a big one?

September 15th, 2017, 02:41 PM
How deep are San Andreas' quakes?

This one was about 38 km underground.

September 15th, 2017, 02:59 PM
Shallower--like 10-20km, I think. The subduction zone quakes tend to be deeper, FWIU.

I felt it a little. I was on a new building on the side of a mountain, nice view of the city and pretty solid foundations.
The sounds, though, they were bowel-emptying!

As for damage, as Swervo said, it was in central Mexico, and people in Mexico city were hit hardest. It's an odd quake, because it didn't originate at either the plate's rifts or the subduction zone, so its violence was unexpected.

September 19th, 2017, 05:48 PM

The mysterious brigades at Alvaro Obregon 286 (https://translate.google.com/translate?sl=es&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fwww.ejecentral.com.mx%2Falvaro-obregon-286-el-misterio-del-sismo%2F&edit-text=)

In a few minutes, more than three thousand kilometers from the epicenter of the emergency in Mexico City, a minister and two foreign ministers agreed that 122 specialists, including rescuers and engineers, would travel to Mexican territory. What seemed like sending international aid to the disaster, in fact hid an urgent mission: rescue two targets listed as top priority.

They came quietly. No one prevented them from crossing the security lines in the direction of the remains of the collapsed building. Marinos, federal and Mexico City police officers opened the way to the mission led by Colonel Dudi Mizrahi, a civilian communications expert recruited by the IDF specifically to command it.

As the data were confirmed against the architectural memory of the building, Kabitke transmitted the information to the members of the Israeli team that would execute the rescue of the target by which they had arrived at Mexico. US rescuers supported them so that it was the Israeli team that coordinated the rescue operations, thereby displacing Mexicans, Spaniards, Colombians and Koreans, who were ordered to carry rubble.

The Israel team never said that they were looking for a specific person, simply that they were helping in the rescue tasks, but in reality they were only interested in one person, and it was a woman who was on the 2nd floor, in the offices of Valora Consultores , in one of the points of greater complexity, because it remained trapped under a concrete block. Neither the shabbath , the Jewish holy day nor the celebration of the Rosh Hashanah , the Jewish New Year, which coincided with this date, stopped the work.

The protocol launched 36 hours earlier already had the first 17 elements of the Emergency Military Unit (UME) on Mexican soil as advanced to recognize the terrain of the tragedy and plan the rescues. On 22 September, on board an Airbus of the Spanish Army would arrive at the capital of the country another 37 staff.

"The first impression was that maybe the Attorney General came to do the survey, the photographs, but no. Everything was done by agreement with the Spaniards, because they wanted to remove all the bodies, because apparently they were not only looking for this body (Gómez Varo's), but strange documentation that he had with him", said Jorge Enrique Gómez Zamarripa, ex-husband of one of the victims of the second floor.

That article needs to be picked up by English-language media.

It's a reputable source, homes! They constructed the narrative from interviews and documentary evidence.

In the days after the quake, I heard an interview with a widower was on the news complaining about the lack of information and transparency surrounding the rescue work at Obregon 286, his wife was working for a PPG subsidiary and had been called to a meeting at Valora's offices where she died when it collapsed. His opinion was that it was all too shady.

Meanwhile we've had at least a couple of 4.5+ seims per day in the last four or five days, it kinda dizzies you. Spare a thought for the people in the isthmus (https://en.wikipedia.org/wiki/2017_Chiapas_earthquake#Aftershocks), folklore says they haven't stopped shaking since last year.

I can't even imagine. We get a 3+ and everyone goes crazy. Stay safe.

Indonesia death toll @ 1400 and rising. Plus they now have a volcanic eruption in the area.

damn nature, u scary...


This is what I'm referring to...66 seconds!

Attorney on the right ducked under something substantial and hung on like you're taught to.

Brian, shaky morning eh?

July 4th, 2019, 12:45 PM
LA wasn’t too bad.

July 4th, 2019, 01:02 PM
My buddy in LA had about 1,000 gallons knocked out of his pool.

July 4th, 2019, 02:12 PM
LA wasn’t too bad.

Good to know!

July 5th, 2019, 08:22 AM
Another big one (mid 5) at 4 am local time in Southern California. Is that common?

July 5th, 2019, 12:07 PM
Yes, after a movement the earth settles down thru a sequence of events. Thankfully.

July 5th, 2019, 12:30 PM
Yeah, after shocks of smaller magnitudes are quite common.

We’ve been anticipating a BIG one for quite sometime... or geologists believe we’ve been overdue for a BIG one based on historical data...

I suppose it’s better to have more of these 6 pointers to relief the stress build up rather than to have one big 8 pointer that end up destroying nearly everything...

Heh, I was up in Portland, Oregon at the time, where I managed to miss one of only five tornadoes they've ever had by about 45 minutes. My flight landed at 6:15, the tornado passed 3 blocks from where we were staying at 5:30ish.

I should probably play the lottery.

Yeah, aftershocks are basically a given.

Tom Servo
July 5th, 2019, 07:20 PM
Well, I did just feel a 4.8 aftershock here in West LA, so that 6.4 probably felt pretty substantial.

Tom Servo
July 5th, 2019, 07:22 PM
Holy crap, then a looooooooooooooong one. No big jolts, but long rolling...

Edit: 7.1 aftershock, so stronger than the first quake. Not common, but not unheard of.

Edit 2: Downgraded to 6.9.

Edit 3: USGS saying depth was 0.9km. They're usually more like 8-12km. That's crazy shallow.

Edit 4: Looks like USGS have upgraded it back to 7.1

Edit 5: Caltech seismologist on TV says depth is more like 16km. That sounds more normal.

July 5th, 2019, 07:43 PM
Can after shocks really be bigger?

Maybe yesterday’s was a fore shock!!!

If trend continues, maybe we’ll get an 8 pointer tomorrow... we are way overdue for a big one. To have some fore shocks to relief a stress a bit was probably good.

Tom Servo
July 5th, 2019, 08:02 PM
Turns out you're right, if a later quake is larger, they rename the previous one a foreshock, so this would be the main event at this point.

Tom Servo

Gonna suck to live in Ridgecrest. I imagine this will be exciting for the people stationed at China Lake or Edwards AFB.

A quake this large will have aftershocks for years.

Don't worry Californians, I'm 100% certain that Trump will make sure NO federal aid will come to California since people there say bad things about him.

Tom Servo
July 5th, 2019, 09:48 PM
You are 100% right that he won't for that reason and he also won't realize that Ridgecrest is solidly pro-Trump. He took the county 53% vs. Clinton's 40%.

July 6th, 2019, 08:16 AM
Ridgecrest is a smaller town in the desert, not wealthy. My sister lives there but she has been away this week. We'll know more about the damage tomorrow. She did have a neighbor look in her windows and her Miata fell off its jackstands at the first quake on the 4th.

I felt only a little gentle rolling up here in Fresburg. I was working on my car both times and both times I saw the car rock before I felt the ground move. Suspension is definitely too soft - where's all my low speed compression damping? :lol:

Tom Servo
July 6th, 2019, 09:27 AM
Oh wow, yeah, that's probably the closest reasonably sized city to the epicenter. It's about 11 miles away, right?

On the plus side, I haven't heard much about major damage there, mostly things falling off shelves and stuff like that, and a couple of structure fires due to broken gas lines. Hopefully the damage to her place (and the Miata) is minimal.

July 6th, 2019, 05:07 PM
President actually called and said he wish to help! Guess he knows he’s helping the Californians who supported him! Anyway, you guessed wrong mr2! :p

Was just reading an article in the Times about how structural engineers were sent to Ridgecrest to survey the damage and ended up finding very little. They're crediting the fact that it's a lot of newer construction that's more earthquake resilient. Hopefully that means good things for Cuda's sister.

July 11th, 2019, 08:23 AM
That's pretty amazing. Northridge quake was only 6. something and that caused quite a bit of damage and deaths too, right? Glad they survived that 7.1 well. :up:

July 11th, 2019, 09:12 AM
Oh yeah, I should be a good person and provide an update. Forgetful me. Anyway things are well for the most part. Someone shut off the water to her house and her cat ended up pretty hot since she uses a swamp cooler instead of AC. But the cat recovered quickly. The Miata seems to have also escaped its fall from on high (it was on stands high enough to remove the transmission on a tranny jack out from underneath) with little damage. Just the front bumper cover, a headlight cover where the prop rod detached from the hood and the hood came down, and the brake dust shields. Kind of amazing really. The house is otherwise okay, some things fell from shelves and broke on the floor but not as much as feared. The fridge moved a couple feet out from the wall but stayed upright. We think she got off easy considering the magnitude of the quakes.

Reports have been that these have been 'rolling' quakes, so I can see the damage being less severe than a quake that shakes more violently. IIRC my sister's neighborhood was built in the 80s.

Roller or not, that's a pretty great outcome from a 7.1 that was 10 miles or so away. Also very happy to hear that the cat is okay!
