A massive 7.6 magnitude earthquake struck the Caribbean on Saturday, causing tsunami consultations in Puerto Rico and the US Virgin Islands, according to the US Geological Survey.
Temblor, about 130 miles southwest of Georgetown in the Cayman Islands, is shown at 7:23pm in the Atlantic Era, at 7:23pm.
USGS data previously reported to be 8 in size.
As seismologists review available data, they may modify the reported magnitude of the earthquake. Additional information collected about earthquakes could encourage USGS scientists to update their Shake-severity Map.

Aftershocks can occur days, weeks, or even years after the first earthquake. These events can be as large as or more than an early earthquake, and can continue to affect already damaged locations.
When an earthquake and aftershock occurs
Source: US Geological Survey | Note: Shaking category is based on the revised Mercalli Intensity Scale. Once aftershock data is available, the corresponding maps and charts include 100 miles of the first earthquake and earthquakes within seven days. All of the above occurs during the Atlantic period. Shake data is on Saturday, February 8th at 7:42pm, during the Atlantic Ocean. Aftershock data is Sunday, February 9th at 5:08pm, during the Atlantic Ocean.
