Earthquakes


Spatial Analysis

The 2015 earthquakes caused great damage in Bhakatpur, Nepal. These photos are overlaid on a damage proxy map derived from COSMO-SkyMed satellite data. Colors show increasingly significant change in terrain/building properties (including surface roughness and soil moisture). Red is most severe.

Developing Earthquake Damage Maps from Satellite Imagery

Researchers are working on developing remotely sensed maps that may assist locals in assessing damage and managing the aftermath with future earthquakes.

GPS

Current GPS permanent station network in Southern California, showing movement of locations throughout the region because of the large scale movement of the Pacific Plate relative to the North American Plate.

Using GPS to Monitor the Earth’s Movement

Earlier this month, a network of research stations located across Southern California and Baja California was dedicated in order to detect minute movements of the earth. On July2, 2001, the 250th station was installed. Each of the 250 stations in the Southern California Integrated GPS Network (SCIGN), is linked to a […]
