Flooding the Himalayas

Just a quick post today as I've been traveling.

Reader Chris P. sent in this map showing tsunami risk around the world:


I don't have a larger version but here is Chris's comment:

 Not that residents of Lake Tahoe should worry about tsunamis, but the map makes it look like they should...


I'm not sure what's going on here because in some cases (India, Australia), apparently the entire country is subject to tsunami risk. Surely, the water won't rise up the Himalayas?

I thought I was safe in Sydney, Australia living 30km from the sea and about 200m elevation, but I don't think I will survive a wave that is going over 1000km inland.

Entertaining detail: Lake Tahoe is actually vulnerable to tsunamis:

(Note that in this news article they correctly define seiche, but get a little confused. The landslide-generated wave that happened thousands of years ago would generate a destructive tsunami. There'd likely be a seiche that resonated for a while after the tsunami, but it would be unlikely to be as destructive as the tsunami itself.)

Seems like the map in question could be greatly improved if cities vulnerable to tsunamis were identified by points with colors to indicate something about degree of risk, and if each point linked to a tsunami inundation map for that city.
