Below you will find general information on how local tsunamis are generated by earthquakes as well as animations, virtual reality models of tsunamis, and summaries of past research studies. The scope of tsunami research within the USGS, however, is broader than the topics covered here. USGS researchers have also provided critical research toward understanding how sediments are transported during tsunami runup (see, for example, analysis of deposits (1.8 MB) from the recent Papua New Guinea tsunami) and deciphering the geologic record of prehistoric tsunamis (for example, in the Pacific Northwest). The USGS also collaborates with the tsunami research group at NOAA. As part of this effort under the National Tsunami Hazard Mitigation Program, the USGS has upgraded the seismograph network and communication functions of the west coast tsunami warning system (termed CREST -- Consolidated Reporting of EarthquakeS and Tsunamis).

Sounds about right. I know as they get bigger they get bigger, if you know what I mean. All those quakes in the Bay Area I know it was 10X .

Here in Alaska we have had 2 small quakes in the last week. Nothing near 8.9 obviously .
