Earthquakes of this size are known to generate tsunamis dangerous to shorelines near the source,
It was shallow, with a depth of barely 7 miles,
This was a lateral 'strike-slip' quake; minimal up/down motion, so very low tsunami threat,
With the latest modeling and information, the tsunami threat has passed. There are no alerts posted for the United States or international partners. The tsunami threat has passed."
While that sounds small, it's evidence and confirmation that a tsunami is occurring due to a significant earthquake,
Actual amplitudes at the coast may vary from forecast amplitudes due to uncertainties in the forecast and local features,
Although a high impact event is not anticipated, as a safety measure no one should be in the water until further notice. It is important to follow official information and avoid the spread of rumors,
A Tsunami Threat continues for Cuba, where a tsunami may reach 1 to 3 meters above the tide, and Honduras and the Cayman Islands, where a tsunami may reach up to 0.3 to 1 meter above the tide,
Luckily, the remote location of these earthquakes limits the potential for significant damage due to shaking,
Large earthquakes at this location of the plate boundary are not unexpected,
All tsunami forecast water levels are below 1-foot with earliest arrival times in about 1 hour in Puerto Rico, ... A one to three-foot tsunami is still an impressive force of nature capable of strong and unusual currents, impacting boats, harbors, and piers. It's not a surf wave. Stay away from the coast in the Advisory area.”
Based on all available data... the tsunami threat from this earthquake has passed and there is no further threat,
Residents living near the coastline are encouraged to move inland."
