SAVE MONEY ON TRAVEL DEALS

The videocast and accompanying chat from NASA's Jet Propulsion Laboratory in Pasadena, Calif., will air on the "NASAJPL" channel Monday beginning at 8 p.m. EDT.

"Scientists use a broad array of tools to study earthquakes and their processes from the ground, air and space", NASA said in a statement. "Space-based technologies like those being developed at JPL can image minute Earth movements to within fractions of an inch, measuring the ground deforming along faults before and after earthquakes."

Participating in the videocast will be Andrea Donnellan, JPL geophysicist and NASA's program area lead for natural disasters, and Maggi Glasscoe, a JPL geophysicist

Viewers may submit questions over Ustream or via Twitter. But people unable to take part in the live chat may submit questions in advance to chatquestion@jpl.nasa.gov and watch the archived video at a later time.

Twitter users may send their questions to @NASAJPL using the hashtag quakechat.

The videocast will be available on Ustream TV at http://www.ustream.tv/channel/nasajpl.
