This a big one.
Being a Californian I've lived through my fair share of quakes.
Loma Prieta was a 6.9, but lasted a long time, I was at the time living the in North Bay, and actually was driving on the lower deck of I880 literally 30 minutes before the bridge collapsed, that was a bullet dodged
Northridge 6.8 i was on I5 driving to a meeting in Long Beach.
I got half way there before I heard on the radio the bridge had collapsed
My scariest was when I was in Tokyo for the grand opening of my company's new office. I was on the 25th floor when the Fukushima quake hit when all Hell broke loose, it was 9.0. Tables, chairs started rolling around the office seemed to on for ever.
Tribute to Japanese engineering nothing collapsed, and all through it I was messaging my boss in San Diego, power, internet nothing went down
A 7+ earthquake anywhere in SE Asia (exclude Singapore they don't count), given we all are pretty savvy about construction methods and adherence to any building codes is always going to be deadly
