These fantastic images are available as a map view or as perspective
views looking North, East or West. We also have close ups of different
places of interest in the area. Developed by Robert E. Crippen (JPL) and
Ross Stein (USGS) these images drape Landsat TM satellite imagery over
Digital Elevation Models to show the bay as it has never been seen before.
The vertical exaggeration in the oblique views is three times; the view
angle is 20 degrees below the horizontal. Active faults (which slipped
during the past 10,000 years) are from C.W Jennings, Fault Activity Map
of California (1994). The offshore portion of the San Gregorio fault is
modified after M.L. Zoback et al (Journal of Geophysical Research v.104,
1999).

places of interest in the bay area are also available.
Historic Earthquakes |
Aside from the aesthetic value of these images they can also be
a valuable rescource for scientist who can use them to display earthquake
information clearly. Offering 'clickable' versions of these images
on the web to make geological and seismological information available
to the public in a easy to understand way is a top priority for this
site. You can view an example of these
developments with historic earthquakes of the bay area displayed on
a north view image. |
