Earthquakes in the DR

[DR Solar]

Side note. We lived in San Francisco when this one 6.9 hit. NO Warnings at all. Most buildings and infrastructure had been built/upgraded for earthquakes yet the damage was pretty bad.

I can't imagine what a 7. would do here.

I was in Northern Haiti for the 2010 quake. It was devastating there because of the influx of refugees. We felt it but had negligible damage. I don't want to go thru that again.

Influx of refugees? Before the quake? Explain please.

Influx of refugees? Before the quake? Explain please.

No, after the quake. Probably within 48 hours.

I KNEW I felt something when I got up to drain the firehose this morning.

They are usually so slight I have a hard time figuring out if it's my bad balance or an actual tremor.

I was sneezing in that moment, a worker told me just shaked very strong and I joked was my sneez, then I received the notification just after I said that.

Temblor de 4.7 grados se produce en Punta Cana - N Digital

Un sismo de magnitud 4.7 en la escala de Richter se produjo la tarde de este miércoles al noreste de Punta Cana, provincia La Altagracia, a una profundidad de 5.9 kilómetros en el océano Atlántico.

FYI - The Headline: "Tremblor de 4.7 grados se produce en Punta Cana" reported by N Digital is quite far fetched..

No where near Punta Cana - Actual location was 60+ miles NE of Punta Cana, way north, out in the Atlantic...

 

[Chirimoya]

That would explain why no one has felt it here.

Posted as a reminder that the shaking from an earthquake is not the only threat our island nation faces when it comes to these events. Nothing to worry about from this earthquake but this may not always be the case. Of particular concern is the major fault that runs east to west in the ocean off the north coast of the island - the North Hispaniola Fault and portions of the Puerto Rico Trench. Both of these areas of active seismic activity are thrust zones that are more than capable of producing a large tsunami under the right conditions. Fortunately this quake was nowhere near us. These large destructive waves can travel large distances quite quickly. As far as I know the Dominican Republic has no tsunami early warning system in place to notify citizens of inbound threats.


PRELIMINARY EARTHQUAKE PARAMETERS

---------------------------------

* MAGNITUDE 6.6
* ORIGIN TIME 0651 UTC SEP 6 2020
* COORDINATES 7.5 NORTH 37.1 WEST
* DEPTH 10 KM / 6 MILES
* LOCATION CENTRAL MID-ATLANTIC RIDGE

EVALUATION
----------
* AN EARTHQUAKE WITH A PRELIMINARY MAGNITUDE OF 6.6 OCCURRED
NEAR THE CENTRAL MID-ATLANTIC RIDGE AT 0651 UTC ON SUNDAY
SEPTEMBER 6 2020.

* BASED ON ALL AVAILABLE DATA... THERE IS NO TSUNAMI THREAT TO
CARIBBEAN COASTS FROM THIS EARTHQUAKE.
-------------
"A dozen major earthquakes of magnitude 7.0 or greater have occurred in the Caribbean near Puerto Rico, the U.S. Virgin Islands and the island of Hispaniola, shared by Haiti and the Dominican Republic, in the past 500 years, and several have generated tsunamis. The most recent major earthquake, a magnitude 8.1 in 1946, resulted in a tsunami that killed a reported 1,600 people."
