Just experienced my first earthquake ever.

Very brief (10 seconds) 4.3 hit Guanacaste Province, Costa Rica at 3:08 PM.

Spilled my cup of coffee and knocked over some plant cuttings in water. The howler monkeys got shaken awake and are still complaining.

That first one always gets your heart racing. 4.3 isn’t huge, but when everything shakes and the animals freak out, it feels massive for those few seconds. Glad it was minor though.

Again, I slept through it.

Among the reasons I moved to New Mexico in 2008: No earthquakes. No volcanoes. No tornadoes, although shortly after I moved here in 2008 the Earthquake Gods were clearly looking for me, as a couple of minor quakes happened in the southwest portion of this state (next to Texas) but nothing within a couple of hundred mile of me.

when it hit. We were a least 30 miles from the epicenter. It was the most surreal frightening experience I have had to this day.

My friend, whom I was working with at the time, his wife was at home at their house in Northridge. She later said that it sounded like explosions going off under the house.

Still after that one in the sea early this year, I started keeping an igloo full of water, drinks and snacks just in case I’m stuck in here after one.

I love this website

I grew up with them in San Francisco and STIL, so many decades later, associate sirens with earthquakes - and I don't even live in an area where they are prevalent anymore!

11. I felt one in 1980 in Phila of all places.

"In Pennsylvania, Montgomery County experienced a series of quakes during three months in 1980, the largest centered in Abington at magnitude 3.7 on March 11. The quakes—located around the Huntington Valley fault, running through Glenside, Abington, and Jenkintown—began on March 2, 1980. Because of the fault’s proximity to the Montgomery-Philadelphia county line, the city felt the larger quakes. The activity prompted Penn State University and the Lamont-Doherty Earth Observatory of Columbia University to place monitoring stations around the area. After the sequence ended, Temple University students distributed surveys to local residents to help determine the perceived intensity of the quakes".

I was in ceramics class and it was a sunny day in the Phila suburb and I thought I heard thunder. No one else did. It turned out to be one of a series.

I moved to San Diego and in 1987 there were 2 big enough to wake me up. The trees and phone wires were swaying. I slept with a pair of jeans and sneakers by the apt door for many months.

... nothing big, but it rattled the glassware. I think I slept through one, too. But when I lived in Santa Barbara, well that was a whole 'nother story. A quake out there definitely got your attention.

while working on the 25th floor of a Seattle high rise. lots of sway and damage in the Pioneer Square section. That was one to remember. When I got home all the pictures were on the floor and the dogs were really rattled. I keep waiting for the really big one and that would be scary as shit.

Loma Prieta quake (17 October 1989, 5:04 p.m.); first reported as a 7.1, then downgraded to 7.0 and finally to 6.9.

We were about 30 miles from the epicenter. Now we're right around six.

I do not want to do that again. But, if I live long enough, the Hayward Fault (East SF Bay) quake that's been predicted for about the last 25 years will be significantly worse. It could happen 10 seconds or 10 years from now, but it'll happen.

strength almost exactly from how it feels.
Biggest was the Loma Prieta in San Francisco in ‘89. 7.1.
Second biggest was in Costa Rica. Roads were blocked by landslides for a few days.
4.1 is big enough to feel, but not enough to do much damage.

when I was at the newspaper in Hollister (literally two blocks east of the San Andreas Fault). I'd call everybody's name in the newsroom, they'd give me their guess and I'd write it on the white board. I and another guy who'd been there awhile usually cane within 0.5.

We had three or four per year, but most were only in the 3's. I remember only one that rated a story on A1.

through the mid 2000s, it was amazing how quickly we got used to quakes. Anything less than 5.0 never really registered except for the occasional dish rattle. The oddest one we went through we had just moved into a house, still had boxes stacked everywhere, and we noticed our dog eos staring at the floor. I heard what I thought was a big truck rumbling past the house, then looked up and saw our dining room chandelier swinging from side to side. The odd thing was that none of the stacked boxes tumbled to the floor. Quake was later rated a 5.2.
The scariest was the Nisqually Quake. That was a 7.2 or 3, if I remember correctly. Lots of brick facade buildings facade came down, office buildings had broken glass falling to streets below...yikes.
