BGS ALERT: POSSIBLE SONIC EVENT CLEVELAND 24 AUGUST 2007 09:00-09:15 UTC

BGS has received information, via the Media, of a felt event, sometime
between 09:00 and 09:15 UTC this morning, in the Redcar, Saltburn,
Marske and Guisborough areas of Cleveland.  Reports describe "heard a
bang then felt a rumble" and "the house shook". Data from the BGS
rapid-access networks in the region were examined but no earthquakes or
signals consistent with a sonic origin were detected.  However, the
reports received are consistent with historical observations received
for previous events with a sonic origin.=20

Both RAF Flying Complaints and British Aerospace were contacted but
neither could confirm if aircraft were operational at the time.
