Shake intensity

Two strong quakes struck off the southern coast of Cuba on Sunday, according to the United States Geological Survey.
The larger, 6.8-magnitude quake happened at 11:49 a.m. Cuba time about 24 miles south of Bartolomé Masó, Cuba, data from the agency shows. It shook the island about an hour after a quake in the same area with a magnitude of 5.9.
People at the U.S. Navy base at Guantanamo Bay felt at least three tremors or tremblers on Sunday afternoon. No injuries or damages were reported there.
As seismologists review available data, they may revise the earthquakes’ reported magnitudes. Additional information collected may also prompt U.S.G.S. scientists to update the shake-severity maps.
Aftershocks in the region
An aftershock is usually a smaller earthquake that follows a larger one in the same general area. Aftershocks are typically minor adjustments along the portion of a fault that slipped at the time of the initial earthquake.
Quakes and aftershocks within 100 miles

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 Cuba time. Shake data is as of Sunday, Nov. 10 at 12:05 p.m. Eastern. Aftershocks data is as of Sunday, Nov. 10 at 1:36 p.m. Eastern.
