Where are natural disasters supposed to hit in Seattle?

The most likely thing that would be a danger to your children is by far the traffic, just like almost any other place in the USA.

The volcanoes USUALLY are not a major threat if you don't live practically on them or along a river with a source that drains them. Unfortunately, quite a bit of the housing occupies one of those two places for one of the several volcanoes with eruption potential. The ash can be slightly hazardous and cover great distances downwind (hundreds of miles), but mostly it is a nuscience and damages property such as automobile paint and engines.

It's very rare a tsunami makes it onshore more than a mile, and that is only on very, very low relief coastline facing the open ocean. Most tsunamis are only a few feet high and don't make it all the way up the beach, but those don't make big news. In addition, bays shaped like Puget Sound are pretty good protection. Unless you are looking at beachfront property, it's not something to worry about either.

Earthquakes in Washington state are not uncommon, but usually do very little damage. There have been a few exceptions that you can read about here: http://earthquake.usgs.gov/regional/states/washing...

The volcano and tsunami warning systems are pretty good. Earthquakes, not so much.

Hurricanes, tornadoes, hailstorms, blizzards, earthquakes, volcanoes, floods, avalanches, animal attacks, and all other nature-cause violent deaths combined come no where close to matching the thousands per month that die on the highways, so logically you should worry less about the geologic hazards of the area than you do about driving to the store. Would you let that stop you from living somewhere so beautiful? Living with phantom fears isn't much of a life.

All in all, you'd be told well in advance if a volcano was going to blow. Geologists are very good at monitering them, and learned a lot about prediction from Mt. St. Helens in 1980. But seattle happens to be very close to 3 dangerous volcanos., however most towns are a safe distance away, so they will make sure you are in time.

You certaily picked a very techtonically active place to live. Very beautiful though.

You'd be amazed how rare a tsunami is. It takes an earthquake to hit just right, and create and sustain deep sea waves. The massive earthquake is more in the California region, however, you may feel it. The damage is still unknown, but there certainly is a lot of tension building up.

Hope my earthly blabbering helped a bit.
