Geophysicist and geologist Tanya Atwater talks about the correlation between plate boundaries and earthquake distribution.
Scientists attempt to reconstruct Earth's history so as to better understand the current state of geologic affairs, including those forces that cause plate movement.
Whether studying earthquakes, volcanoes, or other geologic events, scientists usually focus their attention on plate boundaries and plate movement.
With the advent of plate tectonics, it's become apparent that episodes of extreme geologic upheaval--like earthquakes--are much more than simply random events.
Many scientists believe the plate tectonics process begins deep within the Earth. The challenge is to gather reliable data about an area that no one has ever actually explored--at least not directly.
