|Earthquakes: The Prehistoric Record|
Geologic features altered by earthquakes provide striking evidence of the power of seismic events. This video segment explores the research of Dr. Kerry Sieh, a geologist at the California Institute of Technology, who is dating sediment layers broken and offset by earthquakes in the past to determine the rate at which strain is accumulating towards the next event. The segment is three minutes nineteen seconds in length. A background essay and discussion questions are included.
