Strong Earthquake Along Northern Mid-Atlantic Ridge. No Tsunami Threat.

At 3:57PM Thursday 14th February 2019, a Strong Magnitude 6.1 Earthquake has occurred in the Northern Mid-Atlantic Ridge, approximately 3,754 KM NE of Trinidad and Tobago at a depth of 10 KM.

This event occurred along one of the many transform boundaries along the Mid-Atlantic Ridge along the Oceanographer Fracture Zone. These boundaries occur along two plates moving laterally past each other with minimal effect on the above water column to produce a tsunami. The largest earthquakes in recorded history that occurred along this fracture zone were magnitude 6.3, occurring in 2010, 2003 and 1990.

Large earthquakes are not uncommon for along the Mid-Atlantic Ridge, but are nonetheless, quite threatening. There is NO tsunami threat.

Closer to home, each year, over 1200 earthquakes are recorded in the Eastern Caribbean. On average, the Eastern Caribbean has seen a pattern of quakes within M7.0 to M7.9 every 20 to 30 years. That pattern has stayed true and was last seen in an event north of Martinique in 2007.

Historical patterns indicate earthquakes at and above the magnitude of 8.0 on the Richter Scale have occurred every century or so in the region. The probability of another event at that level is high since the last >M8.0 earthquake occurred in 1843.

Now, more than ever, is the time to create or go over your earthquake preparedness plan and know what to do during, before and after an earthquake. See here for more details: https://www.ready.gov/earthquakes

The M6.1 Earthquake has been reviewed by the United States Geological Survey and this is the final solution.
