USGS seiche
Earthquake induced seiches are interesting because of the risks to nuclear spent fuel pools, and because they show that, depending on geology, impacts from earthquakes can be felt almost 7,000 km, over 4,000 miles away!

A [seismic] seiche is the sloshing of a closed body of water from earthquake shaking. Swimming pools often have seiches during earthquakes.http://earthquake.usgs.gov/learn/glossary/?term=seiche

The Great Alaska Earthquake of 1964 made water slosh on the US Gulf Coast! The 1950 Tibet earthquake impacted water in Norway and the UK!

Local Impacts of the 1964 Alaska Earthquake:
Great Alaska Quake 1964 NOAA
Great Alaska Quake 1964 US Army http://en.wikipedia.org/wiki/1964_Alaska_earthquake

Because both seiches and seismic intensity depend on the horizontal acceleration from surface waves, the distribution of seiches may be used to map the seismic intensity that can be expected from future local earthquakes.http://pubs.er.usgs.gov/publication/pp544E

If you have observed water sloshing back and forth in a swimming pool, bathtub, or cup of water, you…
