A portion of the 800-mile-long San Andreas Fault as it runs through the San Francisco Bay Area is seen from the upper left to the lower right of this image. The development in pink and green is San Mateo and Burlingame. Foster City, which is built on fill, has curved streets extending into the bay. The fault forms a trough that is filled with water at Crystal Springs Reservoir. Scientists will use space-based radar along this same flight path over the next years to look for changes in the ground surface along the fault.
