My fear of earthquakes is more about the ground opening up and you just falling in
If an earthquake is strong enough, you don't even have to worry about the ground opening.
Back in 1964 alaska had an earthquake that was a 9.4 magnitude. Caused tsunamis in Japan and the west coast of USA. I think it was northern Cali that ended up getting damaged a little bit in a town or two. For some reason I want to say San Francisco had a few buildings get fucked up from the tsunamis that happened I might be mixing up events though. I know the west coast for sure got hit by tsunamis due to the AK earthquake, damage or no damage.
Back to my point though, the earthquake in 1964 was so strong the when the ground started to rumble the vibrations were so strong and rapid it essentially liquefied the ground in different areas. I'm talking Cars on the rode sunk into the concrete and when it was over, you could have thought some shitty construction job was done just trying to cover the car with cement because the car was now a part of the road. People walking around in this area now called earthquake Park on the outskirts of anchorage, it was already pretty soft ground. Just a lot of damp soil and trees along the coast, but when the earthquake happened it loosened up that soil so much that people just fell into the earth. When it was done, no holes where the people fell through. The soil was just gathered together and packed down like it had been. They tried to retrieve the bodies, but once the waves started to hit, erosion took a ton of the area into the water so they weren't able to find anyone who might have been out there.
I dunno about aftershocks from 1964, but in 2018 there was a 7.4 thats epicenter was only 10 miles north of my city. Thankfully the city learned from 1964 so while it was terrifying, major damage didn't happen. Lots of homes were damaged but not a whole ton of them had to be condemned or moved out of. City was literally shaken up and things got back to normal after a few days. That 7.4 earthquake gave us aftershocks for damn near 2 months straight though. And I don't mean you feel a little rumble from time to time. Im talking the first 2 weeks after that quake, no exaggeration, you would feel the ground jolt anywhere from 1-4 seconds almost every 30 minutes. Ground jolt, whole building will jerk, all you hear was a rumble beneath you and the sound of wood cracking above you. As the days went on the aftershocks would spread more to maybe once an hour, once every couple hours but for real those couple months were the most anxious I had ever felt. Waking up multiple times a night because your window blinds are banging around wildly and stuff like TV or shelves are banging off the wall. I never felt so hopeless in my life lol. Some aftershocks would last so long enough id hear neighbors screaming and running outside their house.
I always had it in my head, but those couple months just put so much more attention on the thought of all this shit could just end. Whenever. And there ain't shit we can do about it. Fuck natural disasters, bros. Lol I'm feeling all anxious just remembering those times. Longest two months of my life. Around week 6 you get to a real "fuck all this shit then!" Moment and don't care about your house crushing you anymore.
