A magnitude 7.7 earthquake struck this Tuesday 80 miles from Jamaica. It managed to shake people in the Caribbean and Miami as well.
According to the latest data coming from CNN, there was also a tsunami of 0.4 feet that’s been recorded in the Cayman Islands at George Town. There were no tsunamis observed at Port Royal, Jamaica, or Puerto Plata, Dominican Republic.
It’s also worth noting that there were a few aftershocks, including one the US Geological Survey said had a magnitude of 6.1.
“Based on all available data, there is no significant tsunami threat from this (6.1) earthquake. However, there is a very small possibility of tsunami waves along coasts located nearest the epicenter,” according to the National Weather Service’s Pacific Tsunami Warning Center.
The quakes came three weeks after a magnitude 6.4 earthquake struck Puerto Rico, CNN reports.
A few hours after the quake, there was a tsunami alert lifted this Tuesday afternoon.
People in Miami felt the shaking as well
At 440 miles from the epicenter of the quake, people in Miami also felt the shaking.
CNN writes that “Miguel Charon was on the 13th floor of a building on Brickell Avenue. He told CNN he felt the walls shake for 30 to 40 seconds. His initial thought was that it must have been caused by a machine of some sort. He said building officials issued an evacuation order, and people left the building in a smooth and calm manner.”
It’s been revealed that this quake seems to have been a strike-slip earthquake – this means that the tectonic plates are sliding against each other.
This is precisely what limited the threat of massive tsunami devastation because such a tragedy is associated with thrust earthquakes where a part of the earth is thrust upward and causes the water to push up and outward, this way creating the killing tsunami.
There are reportedly no casualties so far.
