Barbados Experience Six Earthquakes In One Day

In the space of six hours, the northeast section of Barbados was struck with six earthquakes. Three of the quakes were said to have occurred within minutes of each other, and the strongest had called for immediate evacuation of some building across the island.

At 7:01 a.m. this morning a 5.7 magnitude tremor was recorded and it was followed by another at 7:52 a.m. Later at around 11:16 a.m. there came the strongest which was a 6.4 magnitude quake, which shook the island, sending residents scampering out of buildings. It occurred about 125 km northeast of the capital, Bridgetown; 234 km east of Castries, St. Lucia and 255 km east southeast of Fort-de-France, Martinique.

The other quakes followed at 11:29 a.m. which had a magnitude of 4.1, 11:36 a.m. with a 5.3 magnitude, and at 12:23 p.m. with a 3.8 magnitude.

The powerful shakes were felt by neighbouring islands St. Lucia, Dominica, Trinidad and Tobago, St. Vincent, and Martinique.

Although preliminary information had put all the quakes at a depth of 10 km, the depth assigned when data is too poor to compute a reliable depth for an earthquake, the Seismic Research Centre indicated that the actual depths ranged from 61 km to 111 km.
