I just live here, I didn't grow up here, so I can't tell you much about how kids are trained here. I've never heard of any drills for adults. Also I had never heard of tornadoes here either (though again, I've only lived here a few years), but earthquakes and typhoons are pretty common. Your Wikipedia list is news to me, but looking it over, it seems they're uncommon and relatively minor in size, and greatly overshadowed by the earthquakes and typhoons and tsunami.

That said, it is very common and normal for people to keep emergency backpacks that they can grab and take to shelters if there's an evacuation. I have one in the closet next to my front door. The government also periodically gives out free emergency supplies for people to keep. There's publicized evacuation plans and routes, and places seem like they're prepared for big storms: subway stations for instance have huge doors at the entrances to protect against flooding.
