Shake intensity

A major, 7.6-magnitude earthquake struck in the Caribbean Sea on Saturday and triggered a tsunami advisory in Puerto Rico and the U.S. Virgin Islands, according to the United States Geological Survey.
The temblor happened at 7:23 p.m. Atlantic time about 130 miles southwest of George Town, Cayman Islands, data from the agency shows.
U.S.G.S. data earlier reported that the magnitude was 8.
As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake, and they can continue to affect already damaged locations.

Source: United States Geological Survey | Notes: Shaking categories are based on the Modified Mercalli Intensity scale. When aftershock data is available, the corresponding maps and charts include earthquakes within 100 miles and seven days of the initial quake. All times above are Atlantic time. Shake data is as of Saturday, Feb. 8 at 7:42 p.m. Atlantic time. Aftershocks data is as of Sunday, Feb. 9 at 1:24 p.m. Atlantic time.
