NEW 3-D FLYOVER OF LOS ANGELES-AREA QUAKE FAULTS

     NASA Television today will air a new computer-animated 3-D 
flyover of the Los Angeles area, created with detailed mapping 
data from NASA's recent Shuttle Radar Topography Mission.  The 
video takes viewers zooming along a 90-mile stretch of the San 
Andreas fault to the intersection of the Mojave Desert's Garlock 
fault -- one of the region's greatest quake hazards.  (The tape 
is also available in HDTV format -- call 818-354-6478 for 
details.)  Stills from the video are at 
http://www.jpl.nasa.gov/pictures/srtm .

     The February flight of the Space Shuttle carried the JPL 
experiment, which used a 61-meter long (200-foot) antenna boom -- 
the largest structure ever extended from the Shuttle -- to gather 
mapping data over almost 80 percent of the Earth's surface. 

     Called "the most successful science Shuttle mission ever,"  
the huge amount of data returned from the Shuttle Radar 
Topography Mission represents a giant leap forward in our 
knowledge of Earth's surface.  The 11-day mission has produced 
unrivaled 3-D images of the Earth's surface, which will be used 
for a wide variety of ecological,  geological, meteorological, 
sociological and civil engineering projects affecting the lives 
of hundreds of millions of people for decades to come. 

     The new video highlights the potential of SRTM imagery to 
better understand earthquakes, volcanoes and other geologic 
events.  The video to be shown is typical of imagery which will 
be available of the entire Earth in weeks and months to come.
