Would be cool if Siri had a better answer to "what do I do during an earthquake?"
In Japan, they have earthquake simulators that drive this point home. The old version is a truck whose bed is fitted with a simulated apartment on hydraulic shakers. The newer version is VR.
Your second concern is fire. In Japan, gas is always run through a sensor that cuts the line if shaking is too intense. I’m not sure if California has the same. If there’s a gas leak nearby, that’s the next serious danger after falling objects.
Do NOT get in a doorway, unless it is one without a door. The door is more dangerous than any other damage.
Do NOT run outside, unless it's faster than getting under a table. And if you do go outside, get away from power lines.
* bathrooms with plumbing in the walls are supposed to be a little stronger.
* blankets can help protect you from breaking windows.
* if you are outside, watch out for trees, powerlines, things falling off buildings (tile roofs, pots), esp. brick buildings
It’s definitely not something you want to run on.
I've found Google's AI to be significantly better than Siri.
