Parkfield Quake / Flu Vaccine / Mt. St. Helens
This site contains three radio broadcasts discussing: the Parkfield, California earthquake of October 2004; the Mount Saint Helens volcano; and the shortage of flu vaccine in 2004. The 15 minute Parkfield broadcast explains how the Parkfield earthquake was the most monitored earthquake in history. Scientists are studying the San Andreas Fault in the area. Data collected from the recent earthquake is expected to lead to improvements in: earthquake prediction; and understanding of how earthquake energy builds up as well as the mechanical laws that cause the shaking. The 15 minute Mount Saint Helens broadcast discusses why less seismic activity at the volcano has been observed in 2004, and that danger of an imminent eruption has passed - at least for now.
