An earthquake shook parts of El Salvador last night around 10:30. The USGS and media at first reported a magnitude of 7.4 located just off the coast of Usulután, roughly the same location of the January 2001 earthquake that caused so much damage and loss of life.
This morning, the Ministry of the Environment and Natural Resources (MARN) is reporting that the earthquake was more like a magnitude 6.7 and that the epicenter was about 250 km (155 miles) south of the coast of Usulután. There were supposedly several aftershocks and earthquakes that finally ended around 2:00 am.
We are hearing that communities along the coast felt the earthquake but that it wasn’t strong. La Prensa Grafica said that others around the country didn’t feel it at all. Similarly, we have not heard any reports of damage.
Immediately after the earthquakes, the Tsunami Alert Center in Hawaii issued a tsunami warning, but it was called off around midnight. There was a report of a small wave, around 4 inches high, reaching the coast, but no damage was reported. During a conference call last night, Jorge Meléndez, the Director of Civil Protection, denied the threat of a Tsunami and said that it was the result of a miscalculation.
El Salvador is located on the Ring of Fire; a fault line circles much of the Pacific region. As a result, Salvadorans experience earthquakes on a regular basis. Every now and then there strong quakes that cause real damage. Some of the most notable are the January and February 2001 earthquakes that killed more than a thousand people and destroyed much of the country’s infrastructure. In most recent history, there were significant quakes in 1986, 1982, 1965, and 1951.
If quakes weren’t enough to worry about, El Salvador is entering the most dangerous time of year for flooding. The most serious flooding events in recent history have all occurred between the end of August and early November – the last half of hurricane season. It’s been raining pretty heavily lately and this morning there are reports from around the country of landslides blocking roads and causing problems.
