8.7 earthquake off coast of Kamchatka.

It's very hard to know precisely how large the tsunami will be elsewhere further away, so it's waiting and watching to find out. Probably worth tuning into webcams or news streams as it draws closer

What causes the uncertainty? It feels like it would be (relatively) easy to just math out the energy?

Due to a massive earthquake that occurred in the Pacific Ocean, a Tsunami Warning is in effect for those living in Hawaii. A Tsunami Watch is in effect for Alaska and the Pacific Coast of the United States. Japan is also in the way. Please visit tsunami.gov/ for the latest information. STAY STRONG AND STAY SAFE!

Doesn't work like that. It's not a straight "x magnitude earthquake = y magnitude tsunami" calculation. There are lots of other factors that go into it (mechanism of the earthquake, depth of the earthquake, topography of the seabed and coastline, etc.).

An 8.8 ties it for sixth strongest quake known on reliable modern record

The epicenters for the 1952 quake and today's quake are in the same general area. Only about 20 miles apart or so.

*sigh.....*

highest tsunami reports in Japan so far are 50 cm (about 1'8"), according to the AP

Tsunami warning now in effect of parts of the California and Oregon coasts.

Sounds like more waves are about to hit Japan.
