Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Dominican Republic Quake Report

Posted by feww on April 3, 2010

Serial No  1,528. If any posts are blocked in your country, please drop us a line.


An earlier report of a magnitude 8.0 earthquake in the Dominican Republic that was posted on Fire-Earth was sourced from an automatically generated bulletin broadcast by the European Commission’s Global Disaster Alert and Coordination System – the report now appears to be FALSE

According to other monitoring sources, an 8.0Mw quake has NOT occurred in the region.

Details as they appeared on  EC’s Disaster Website:

Haiti Quake Causes Widespread Death, Destruction

Posted by feww on January 13, 2010

M7.3 EQ Causes Widespread Damage in Haiti

Powerful quake measuring up to 7.3 Mw strikes SW of PORT-AU-PRINCE, many feared dead

FEWW Forecast: Another Major Earthquake Could Strike the Region Soon with a Probability of 60% [P ≥ 0.55]

The quake struck about 15 km (10 miles) SW of PORT-AU-PRINCE, Haiti at an approximate  depth of 10 km on Tuesday, January 12, 2010 at 21:53 UTC, USGS/EHP reported.

The mainshock, as of posting, was followed by at least 3 significant aftershocks the largest of which measured up to 6.2 Mw.

Haiti is the poorest country in the western hemisphere with abysmal civic and urban infrastructure. The aftermath of this quake could well prove to be catastrophic, with thousands of people killed or injured.

PORT-AU-PRINCE has an estimated population of about 1.2 million.

Estimated Population Exposed to Earthquake Shaking:

  • Up to 240,000 people live in the “extreme” and  “violent” zones of the quake epicenter exposed to the earthquake shaking and most severe destruction.
  • A total of 1.2 million people live within the “severe” zone of the earthquake damage.

Tsunami Evaluation


A tsunami measuring 12 cm crest-to-trough was recorded at Santo Domingo in the Dominican Republic and a tsunami less than 1 cm  crest-to-trough was recorded on a deep ocean gauge in the east-central Caribbean.  Based on these data there could have been destructive tsunami waves near the earthquake epicenter but there is not a threat to coastal areas further away.Therefore the tsunami watch issued by this center is now canceled.

For any affected areas – when no major waves have occurred for at least two hours after the estimated arrival time or damaging waves  have not occurred for at least two hours then local authorities  can assume the threat is passed. Danger to boats and coastal structures can continue for several hours due to rapid currents. As local conditions can cause a wide variation in tsunami wave action the all clear determination must be made by local authorities.

This will be the final product issued by the Pacific Tsunami Warning Center for this event unless additional information becomes available.

Historic Earthquakes in the Region

  • Samana, Dominican Republic,  August 04,  1946 at 17:51 UTC, Magnitude 8.0
  • Aftershock,  August 08, 1946 at  13:28 UTC, Magnitude 7.6

The mainshock struck about 370 km ESE of a M8.0 quake which struck about 65 km off the northeast coast of the Dominican Republic in 1946. The large earthquake was followed by a major M7.6 aftershock.

The mainshock occurred about 65 km off the northeast coast of the Dominican Republic, causing severe damage in northern Dominican Republic from Samana to Santiago and Puerto Plata. The quake left about 100 people dead and more than 20,000 people homeless.

“Almost all the people killed were drowned by a tsunami at Matanzas, near Nagua (Julia Molina). Although the waves were only about 2.5 m (8 ft) high at this location, they moved inland several km, causing such severe damage that the town was abandoned. Maximum wave heights were estimated at 4-5 m (13-16 ft) at Nagua. A small tsunami was recorded by tide gauges at San Juan, Puerto Rico; Bermuda; Daytona Beach, Florida and Atlantic City, New Jersey.” USGS said.

The 7.6 M aftershock, which occurred 4 days after the mainshock, generated a small tsunami and caused additional damage.

30 hurt as airliner hits turbulence

Posted by feww on August 3, 2009

Severe turbulence shakes Continental airliner near Dominican Republic

A Continental airliner flying from Rio de Janeiro, Brazil, to Houston, Texas,  Monday experienced severe turbulence at 36,000 feet, injuring more than 30 passengers—at least 4 of them seriously—and forcing the plane to divert to Miami International Airport.

“There were 168 passengers on Flight 128, which was originally headed from Rio de Janeiro, Brazil, to Houston, Texas, according to Lt. Elkin Sierra of the Miami-Dade Fire Department.” CNN reported.

Some of the injured were taken to hospitals in Miami, while others  with less serious injuries were treated on the spot after the plane landed at Miami International Airport at about 6 am ET.

“The Boeing 767 hit turbulence about 50 miles north of the Dominican Republic at about 38,000 feet, according to an official with the Federal Aviation Administration.”

“The airline will decide whether or not to leave the uninjured passengers on the aircraft and continue the flight or disembark the entire aircraft,” Sierra said.
