TRANSCRIPT
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of October 22, 2012.
This week, we get an introduction to the work of College of William
and Mary geologist Chuck Bailey and student John Hollis, who are studying rocks
along the North Anna River in central Virginia for clues to the history of
ancient earthquakes and to where future quakes may occur. Have a listen for about two minutes to this
excerpt from the College’s video, “Looking
for earthquakes: from the riverbed to the research lab.”
SOUND and VOICE.
The Fall Line, or falls zone, along Virginia’s rivers helped
shape the history of human settlement in the Commonwealth. Through modern scientific study of Fall Line geology
and chemistry, this distinctive geographic feature now is helping shape our
understanding of the much older history of earthquakes in eastern Virginia. Thanks to the College of William and Mary for
permission to use this week’s sounds.
For other water sounds and music, and for more Virginia water
information, visit our Web site at virginiawaterradio.org,
or call us at (540) 231-5463. From the
Virginia Water Resources Research Center in Blacksburg, I’m Alan Raflo,
thanking you for listening, and wishing you health, wisdom, and good water.
SHOW NOTES
Figure: Blue shading indicates the Atlantic Coastal Plain, with its
western edge marked by the Fall Line, or fall zone, the region in which the
William and Mary earthquake research on the North Anna River is being
conducted. In Virginia, the Fall Line
approximately follows Interstate 95. Source:
