A minor magnitude-3.7 earthquake
occurred 30 miles south of Grand Cayman at 2:46am Friday morning, but no
damages or injuries were reported.
The United States Geological
Survery confirmed the earthquake, but not until just after 4pm Friday. It occurred at a depth of 6.2 miles.
Hazard Management Cayman Islands
reported a 4.7 magnitude earthquake earlier in the day after speaking to the
Jamaican Earthquake Unit, said Deputy Director Omar Afflick.
“We had a report that someone felt a tremor,”
said Mr. Afflick. “We contacted the Jamaican Earthquake Unit and they confirmed
an earthquake in the Cayman Ridge area.”
The Oriente Fracture Zone is an active
fault line that runs from south-eastern Cuba, south of Grand Cayman along the
edge of the Cayman Trough, and then extends to Guatemala.
Mr. Afflick didn’t know why the
USGS failed to register the earthquake for so long. However, in addition to the
confirmation from the Jamaican Earthquake Unit, there had been other reports of
people feeling the earthquake in Cayman, Mr. Afflick said.
The earthquake was one of two that
occurred along the Oriente Fault line of Friday morning.. A 5.4-magnitude
earthquake also occurred at 7:09am. That quake occurred 60 miles east-southeast
of Guantanamo, Cuba, also at a depth of 6.2 miles.
