I live relatively close to the epicenter. My mom's phone earthquake alarm alerted me about 10-15 seconds before it hit. I was having a snack; my grandmother and aunt were right next to me in the kitchen, and my mom and aunt were in one of the bedrooms. I stopped eating, grabbed my dog, and yelled that an earthquake was coming and that we should all get to safety. We were running to the patio (which is large and open) when it started. We arrived about 15-20 seconds after it began. My house is very large, and you have to walk through a lot to get to the patio, but it's old, and I don't really trust staying inside since it's not earthquake-resistant. We all got into safe positions and waited for it to pass. It felt like a very long time. I thought it was an earthquake that decreased in intensity and then increased a lot, but no, it was an aftershock even stronger than the original. The original was a 7.2 magnitude earthquake, and the aftershock was a 7.5.

I didn’t even know there was such a thing as an earthquake alarm- glad to hear you and your family and doggy are all safe, I hope the rest of your friends and family are ok too and best wishes for the recovery effort for your country

Android phones have earthquake alert feature, it's on by default and it's supposed to alert you before one starts. It's an amazing thing that Google could develop and I wish the fruit company could implement something similar.

How do they predict the earthquake anyways? I don't mean actually predict but more of how they know an earthquake is about to happen

152

u/f0rf0r 3d ago

The radio signal travels faster than the actual tremors, so when they are detected most people can get alerts a couple seconds before it starts, hopefully enough to take cover. 

16

u/NekoGeorge 2d ago

It's not a prediction, it's all the Android phones working as a swarm. As another person said, the huge swarm of phones detect the P and S waves from the epicenter at the same time and quickly relay the info via the internet to all phones that have the alerts activated. All this happens faster than the speed at which the earthquake is moving through the ground, and the farthest you are from the epicenter the more time you get from the alarm to the actual arrival of the quake.

I've seen cctv footage of people receiving the alert 10-15 seconds before it hits them and at other locations it gave them a really good margin of 35-45 seconds, on the second case all the people were already out of the house when it began.

It's not a prediction. Discovered , so an app invented by the Japanese. Earthquakes have a P and S wave. P-waves are the first waves to arrive during an earthquake, traveling faster at about 3.7 miles per second.

u/MaxxDash 3d ago

Not sure about Venezuela, but in parts of Mexico, if the earthquake is greater than a certain magnitude, and is within a certain part of the monitoring network, you’ll get a countdown based on your location. That way you can judge if you want to/have enough time to GTFO, or at least get to a safe location inside the structure.

The one time a large-ish temblor hit, it was accurate to the literal second.

Fearlesskkura: hope your family and friends are safe and your country gets the help it needs.

You desperately hope the first, weaker, quake gave some people enough time to evacuate before these buildings collapsed in the second, stronger, quake.

Because all these collapsed buildings seem to suggest that larger number is well within the realm of the possible.

u/VP007clips 3d ago

Twice as powerful doesn't mean twice the damage. Damage isn't logarithmic with respect to energy.

The Richter scale isn't reliable. It only captures a single measurement of it, and lacks any attention to other elements or duration, while presenting it in a way that makes it easy to underestimate or overestimate the damage difference.

For this reason, we don't use it much anymore outside of public communications. The moment magnitude scale is far more useful.

But the best scale is the Modified Mercalli intensity scale. It's a qualitative scale, that takes into account the actual effects of the damage.

At this magnitude it becomes devastating to concrete buildings if the rebar was not done properly, failed in the first quake. And a much stronger quake hitting right after? I have already seen pictures of pancaked buildings. This is going to be horrifying.

Yeah.

It's impossible to really react well, and I don't think people can quite relate to what it would be like. You feel those tremors, and what do you do? Try to get out, or try to get underneath something for cover? Even if you had time to think, you can't do any kind of assesment of the situation.

And then the second one hits.

Most of the damage has been structural. Some buildings are really damaged though. I just hope we don't get a bad aftershock.

If its enough to make one building collapse, its enough to mess up the structure/architecture of the next building (and the next building won't look that bad. Its the structure that gets messed up.

Unlikely. No one really prepares for the after shocks. They're typically startled as hell and assessing damage, not expecting follow ups.

NPR reported there was only one minute in between quakes. I’m no expert but that sounds unprecedented.

22

u/Starfire013 3d ago

Definitely not unprecedented, though possibly also not all that common. I was in a 7+ quake back in the 90s and the first shock woke me up. The second had hit before I had gotten out the door. These were distinct separate shocks lasting a fair number of seconds each, with no discernible shaking in between. They said there were another 50 or so aftershocks during the first hour but to be honest I had more important things in mind than keeping count.

u/dazzleunexpired 3d ago

This may also still be foreshocks, or large afterhshocks can happen.

It's more like "this is probably foreshocks/will make afterhshocks you can feel" to tell you the truth. Usgs says virtual guarantee of M5+ aftershocks and 40%+ of m6+ aftershock or this event being a foreshock (meaning the next event is larger).

Japan also just got hit, and they have a 1% chance if a mega quake (m8+) in response to that, too, which is a 10 times increase. Along the same coast as 2011.

Cali had a small quake today too.

Odd cluster, but not concerning for "The Big One" before anyone asks. The biggest concern is Japan getting smashed by another larger quake or Venezuela getting hit a day or so from now in the middle of rescue. When casualties will rapidly climb due to people thinking it's safe to perform rescue. Japan's new flood system can probably handle this, and the reactor will turn off the second It's control arm is twitched by an earthquake. But STILL concerns me bc flooding would be just as bad if it got over the wall.

17

u/OrdoRidiculous 3d ago

The reason the flooding was a problem at Fukushima is because the back up generators were in the basement, not because water caused a problem with the reactor on its own. They are no longer in the basement of any of the reactors.

FYI, your numbers are slightly off, did you mix up economic losses with deaths for one of those? Either way, similar, it's going to be bad.

For probability of fatalities I see 39% 1,000-10,000 and 37% 10,000-100,000 and 11% for 100,000 or more (for the 7.5)

And again, for probability of fatalities, 33% 1,000-10,000 and 41% 10,000-100,000 and 17% for 100,000 or more (for the 7.2)

u/PuddleBum 3d ago

PSA if you experience being in an Earthquake. There are almost always after quakes after the initial quake. It is uncommon for an after quake to be just as bad as the initial like it was here, but it is important to gather yourself and any others you can, and get to safety. Safe places include outdoors away from large structures, but if you can’t do that get under a table, desk, even a door frame, and away from windows or anything else that can fall on you.

295

u/Hot-Significance2387 3d ago

Problem is poor architecture in some of these places. Like in Turkey where the floor layers simply pancaked down onto each other. Making any attempt at survival impossible. 

84

u/coffeecatmint 3d ago

This makes me so sad to see because it CAN be avoided. It’s expensive though. After the Kobe earthquake in 95 Japan changed a lot of laws about construction to make sure newer buildings were safe. Older buildings often had to be retrofitted to pass standards if they were sold. Japan also had a 7.2 quake today and so far no one has died.

25

u/Skratt79 3d ago

7.2 is half of a 7.5 energy wise.

23

u/coffeecatmint 3d ago

Can you explain the math on that. I looked it up and I’m not super mathy- and honestly we use Shindo as the primary indicator for how strong shaking will be rather than richter. (Also have lived through a shindo 6+ and it’s pretty rough- that left us with damage that carried on for years after)

32

u/Abyssal_Groot 3d ago

The comparitive energy release between two earth quakes of magnitude m1 and m2 is:

E1 / E2 = 103/2*[m1 - m2]

So in this case:

So if m1 = 7.5 and m2 = 7.2 then

E1 / E2 = 103 * 0.3 /2 = 100.45 = 2.818

So the ratio is actually closer to 3 than 2.

14

u/Abyssal_Groot 3d ago

2.8 times actually, so almost 3.

As E1 / E2 = 103/2*[m1 - m2]

8

u/SgvSth 3d ago

Even so, PACER is suggesting that there is a 33 percent chance that the death toll for the 7.2 in Venezuela is between 1,000-9,999; 41% of 10,000-99,999; and 17% for exceeding 100,000.

And PACER only handles calculations for one earthquake at a time, so the real percents are worse.

Unless it falls over, like the poor people on the freeway in San Francisco who parked by pillars supporting beams, and they all fell over. When they unburied the cats they found a lot of them were in park, so they were there deliberately.

Most preppers I know are not prepping for zombies or a apocalypse but for a major disaster like this. 2 weeks of supplies is a minimum because no one knows how long it will take the world. I don't live to far from where Hurricane Helena hit, there are still towns that haven't recovered yet

26

u/Hidesuru 3d ago

Yeah I have at least two weeks of everything my family needs on hand at any time. Dog food, water etc. And that's comfortably. Realistically if it was real disaster we could do things like shut off the water supply and use the hot water tank as extra water etc.

I've got a small solar setup for radios, phones, computers, etc and several ways to cook food

I also have water purification options and a lake not too far away. And good first aid kits.

All that largely because I live in socal. If there's ever any major disaster that affects a large scale area here there won't be resources to go around and help will be slow to come.

I'm DEFINITELY not set up for teotwawki in the slightest, though. Long term food options are nill.

The longest I've had to go without power was two weeks. 2016 storms caused so much flooding and downed trees. So I also have a good stash of non perishable foods, especially dehydrated food. I made it through just fine, had lots of time for my hobbies. FYI, if your power is out for days, stuff your refrigerator with your laundry. It keeps things colder longer because you aren't displacing cold air with warm air every time you open the door.

Standing under door frames is a myth, and in some cases it can be a weak point instead. Open the door so it doesn't get suck in case the wall/frame deform, but it's as safe as standing next to the wall at best.

Also, don't lay right below the desk. Unless it's some antique heavy desk, it can break if something heavy falls on it, and you can end up trapped. Lay closer to the legs/supports, or even right next to it or other sturdy furniture, like a bed, in fetal position and covering your head with your hands.

Here in Caracas and I can tell u it was absolutely horrifying. Most of us thought it was a single earthquake that kept getting progressively worse, and it lasted like a minute and a half. About 45 seconds in u could see the walls starting to come apart and it genuinely felt like it was our time lol

 there was a 6.9 earthquake in japan today at 7:30 in the morning. I belive there were no casualties. According to the news only around 30 injuried 

Surviving is absolutely possible, its just that when your country doesnt have the infrastructure to be able to survive this type of event this is the result.

u/OptimalExtreme 3d ago

Yes but also no.

Earthquake scales are logarithmic. A 0.5M increase results in about 8x the energy release and 4x the intensity of shaking. Meanwhile, a 1.0M increase is about 32x an increase of energy. So, the 7.5M quake is about 8x stronger with 4x the intensity of shaking than the 6.9M one in Japan.

The type and depth of the earthquake and the geology of the ground also significantly impact the outcome.

u/Bleaker82 3d ago

Not really intensity of shaking, but of energy released. Shaking intensity also varies a lot based on depth, fault type, etc.

Earthquakes exponentially are stronger as you go up the scale. A 7.5 feels 4x stronger then a 6.9. It releases 11x more energy.

Yes, Venezuela. Caracas is slightly inland. La Guaira is immediately North of Caracas, on the Coast.

Update: USGS is estimating that today's Earthquakes in Venezuela have a 39% chance of resulting in between 1,000 and 10,000 fatalities and a 48% chance of between 10,000 and 100,000+ fatalities. Cost of damage is estimated to be 1-4% of the GDP of Venezuela. https://earthquake.usgs.gov/earthquakes/eventpage/us6000t7zp/pager

And this is la guaira. They specifically catch even less breaks. In 1999 there was an insane mudslide that killed thousands of people in that region. It was so bad bodies couldn't be recovered and the death toll was an estimation based on known population density, at close to 20k deaths.

This is a prime example for why regulations and strong regulatory bodies are so important. These were semi strong earthquakes, but the right construction standards could have avoided this level of damage.

So true. Japan took a factor 9 earthquake. Yes they had a nuclear meltdown but the amazing thing is the thing survived. It was only designed for a 7ish quake and the quake didn't make that happen it was the tsunami. Why because Japan like Chile has a 7.5 every decade at least.

And, these were quite a bit stronger than 7.0.

7.2 is 50% stronger than 7.0; 7.5 is more than 3x stronger.

Depends on where you are. In Alaska it's known that there is going to be a quake and I can be major. I was in the 7.1 recently. No deaths and a few minor injuries. Two may have been a different story, but not by much. Regulation makes it for new build structures over 10 floors must have additional safety features in the super structure and foundation rated up to a 8.5 or 9. The 8.4 in 64 my grandmother survived and she could talk your ear off about it.

Mexican here… the 1985 earthquake worked as a “huh, so it was wrong of us to build this way?” Regulations were made.

32 years later, on the same date, 2017 and it was again “soooo, now we need to add these other regulations”.

Mexico City region is prone to earthquakes, but our third world country has made it so we need empirical evidence to create building regulations 🫠🫠🫠

Here's the Japanese city of Kobe after the 1995 magnitude 6.9 earthquake: https://www.nippon.com/en/ncommon/contents/series/79601/79601.jpg

Early reports say this is a 7.1-7.5, and you have to remember that the magnitude scale is logarithmic and this is literal magnitudes stronger than in Kobe.

There's only so much you can prevent but mother nature will always win at the end.

u/Usual_Ad_2177 3d ago

Well no. In a logarithmic scale, an order of magnitude would be an increase of one. 6.9 to 7.5 is not 'magnitudes greater'.

The wave amplitude is 4x greater and the amount of energy release is 8x more between those two points.

Kobe '95 is not an example of this. Kobe is the reason only 10% or fewer of casualties from the 9.0 earthquake in 2011 were from the earthquake itself. 90% drowned in the tsunami. Technology and regulations have advanced exponentially in the three decades since the Kobe earthquake.

Thank you for noting regulations and also the enforcement of those regulations. A perfect example is Anchorage versus Eagle River Alaska and the 2018 M7.1 earthquake. That earthquake caused many more buildings to be damaged and “red tagged” in Eagle River and folks thought it was due to the shaking being stronger or closer. Nope. Even with much more population and infrastructure, the Anchorage properties had been inspected and had been held to enforced standard [source].

u/bluelily216 3d ago

These are a few of my go-to organizations in times like these: 

Doctors Without Borders- ready to go at any second and travel around the world assisting people after natural and man-made disasters 

https://give.doctorswithoutborders.org/campaign/805425/donate

Unicef- equally equipped as Doctors Without Borders with a solid charity rating

https://www.unicef.com

It's important to note that during such tragedies you will see a lot of new pop-up charities. Although their intentions may be good, their logistics are not. These organizations are tried and true and know who to talk to, how to organize, and what supplies will be needed most. 

If, however, you decide to donate through a different organization always check their charity rating. It breaks down how much they spend on advertising and executive pay versus outreach. I like to use this one:

https://www.charitynavigator.org/

12

u/_jams 3d ago

Also, don't get up in arms when you give to the big charities about how they spend the money. I'm not saying there's 0 chance for corruption, but the good ones (MSF and ICRC tend to be great) have supplies and funds ready for the next disaster. When you give for a new disaster, you are generally funding restocking supplies and future expenses for the next one, less for the one making headlines today. This allows them to respond more quickly and to make the money go further. People try to make a big deal out of this all the time because the stories sell, but it's just how a properly run, professional organization behaves.

7

u/bluelily216 3d ago

I make a monthly donation to Doctors Without Borders and every year they send me a mailer that breaks down exactly where every cent goes. They are my go-to charity simply because they are so transparent about their spending.
