How do tsunamis move as fast as jetliners in the open sea? Why does
the ocean often recede before these deadly waves appear at beaches?
How much time do you have to get safely away once you see the sea
retreat?
You might find answers to some of your questions about tsunamis
elsewhere on this "Wave That Shook the World" Web site. But some
queries may require outside help, and that's why we approached
tsunami expert Lori Dengler of Humboldt State University.
Below, see Dengler's comprehensive responses to questions emailed to
NOVA by viewers. Please note: We are not accepting any new
questions.
