Magma Plumes: Experts concerned with abnormal seismic activity in Azores

October 19, 2011AZORESExperts in the Azores have alerted the population of São Miguel Island for seismic activity which they considered to be above normal. The seismic events where located in the system of Fogo and Congro lakes, the central region of the island. “The situation is ongoing and the number of microseisms is slightly above reference values” said Wednesday João Luís Gaspar from the Center of Volcanology and Geological Risk Assessment (CVARG) of the University of the Azores. He also said that the seismic activity was the result of “very low magnitude earthquakes” adding that “none of which have been felt by the population.” Declining to comment on what the evolution of the crisis could be João Luís Gaspar recalled that “seismological activity is difficult to predict,” but that the possibility could not be eliminated of an earthquake occurrence which may be felt by the population. He said, “It does not mean it will happen; only that one cannot eliminate that possibility.” Apparently, it did happen. The region was hit by a 4.9 magnitude tremor at a depth of 12 km today. According to the CVARG website, the Fogo-Congro system is one of the most critical seismologic areas of the archipelago where accumulated tensions exist resulting from the lithospheric interplay of the Eurasian, African and American plates. The Azores are sitting on the so called “Azores triple junction” area where the North American, Eurasian and African plates meet. This area is responsible for frequent geological and volcanic activity on the islands. Periodic volcanic eruptions and earthquake events, with occasional tidal waves, can have devastating effects on the Azorean islands. –PAJ
Magma Plume Activity: A 4.9 magnitude earthquake struck the Azores region and a 5.1 magnitude earthquake was reported on Easter island. Ongoing seismic activity is occurring in the Canary Islands. Three moderate tremors in the 3.8 range also struck in a swarm near the Tjörnes fracture zone north of Iceland. We’re also seeing a volley of tremors in SE Australia. –The Extinction Protocol

    So the Experts, are finally getting concerned…..I am sure that Alvin is not surprised.

    Easter Island again, after only a few days. The Azores beginning, and Ascension only a few weeks ago. El Hierro active, and Iceland awakening.
    Hot spots seem to be getting….. hotter.

    ISLAND IS SO BEAUTIFUL! SHAME ITS GOING TO BE DESTROYED AFTER SO MANY THOUSANDS OF YEARS OF CREATION.
