Radio Cayman reporting:-

*zero chance of tidal wave activity at this time.

Tidal waves occur within a few minutes of an earthquake and rumors of tidal waves are just that, rumors.

* west end of Cayman Brac and north side of Cayman Brac felt it. Only report of damage from there is a picture falling off the wall.

* may experience smaller aftershocks over next few days, same thing that occurred in Trinidad a couple of weeks ago.

* Dr. Margaret Anderson (sp?), University of West Indies Seismic Dept. said it was also felt in Jamaica, and that there have been a spate of moderate to strong earthquakes along Caribbean boundaries at this time - Jamaica, Costa Rica, Guadeloupe, Trinidad, and now it's moved into the northern Caribbean.

Tuesday, December 14, 2004
A strong earthquake was felt throughout Grand Cayman at 6:20 pm on Tuesday, December 14, 2004. According to a preliminary report from the U.S. Geological Survey’s National Earthquake Information Center in Denver, the epicenter of the magnitude 6.7 event was located some 21 miles south of Bodden Town at a depth of 6.2 miles.

Seismicity maps published by the National Earthquake Information Center indicate that this event was the closest to Grand Cayman occurring since 1990.

According to eyewitness reports, the earthquake lasted between 15 and 30 seconds and prompted the evacuation of offices, supermarkets and other buildings, including the airport control tower, where one witness reported the tower was “rocking one and a half to two feet.”
No casualties have been reported.
