You can view historic damage photographs side-by-side with modern photos taken from the same vantage point. Using this self-guided, virtual tour of the 1868 quake in Google Earth you can learn about the 1868 earthquake, visualize its effects, and better plan for its expected repeat.

(Date of Image: November 2008)Ĭredit: Lisa Christiansen, Caltech Tectonics Observatory It is a step toward estimating when the next big earthquake will occur in Sumatra and similar regions previously thought to be at low risk for large earthquakes, such as in China, Java, Japan and Peru. These research results provide a new way to estimate locations and magnitudes of future giant quakes. TO scientists combine field measurements of coral growth patterns, data from GPS stations and sophisticated computer models. New research results by TO scientists show how this region's massive earthquakes (magnitude greater than 8.0) are connected to the continual deformation of Earth's surface, which occurs even during calm times in between the massive quakes (these calm times are called interseismic periods). Scientists at Caltech's Tectonics Observatory (TO) have been investigating the Sumatra region to shed light on what happened during the recent earthquakes and to improve our understanding of the seismic and tsunami hazard associated with such plate boundaries. The colors indicate the depth of the earthquakes, with red being the shallowest and green the deepest. The earthquakes occur at the boundaries between Earth's tectonic plates. ![]()
