Jupiter Today - Calendar of Events Live Web Chat: Earthquakes -- How, Where and Why? The following Web Chat event is sponsored by the NASA JPL Education Office. A magnitude 8.8 quake in Chile over the weekend is the latest in a spate of very large and deadly earthquakes. What causes these temblors? Is there any way to forecast them? Is the recent earthquake activity unusual? Earthquakes provide visible examples of plate tectonics in action.

The text-based chat, intended for middle and high school students and teachers, will be on Thursday, March 4, 2010 at 1 p.m. EST/10 a.m. PST.
