Alentejo: Earthquake with epicenter eight kilometers of Almodovar sense in Beja region.
An earthquake of magnitude 3,1 on the Richter scale with the epicenter about eight kilometers northeast of Almodovar, district of Beja, It was felt on the mainland, according to the Portuguese Institute of Ocean and Atmosphere.
In a statement, the Portuguese Institute of Ocean and Atmosphere (IPMA) It said that the earthquake was registered at 05:46 in the seismic network stations of the continent with a magnitude of 3,1 on the Richter scale and with an epicenter northeast of Almodovar.
“this earthquake, according to the information available to date, It did not cause personal injury or property damage and was felt with maximum intensity III (Modified Mercalli scale) in Beja region”, according to the IPMA.
According to the IPMA, Mercali III in the intensity scale is considered weak, meaning that the shaking can be felt indoors, pending objects baloiçam, It is similar to the vibration caused by the passage of heavy vehicles.
“You can estimate the duration, but it can not be recognized as an earthquake”, referred to Institute.
Earthquakes are classified according to their magnitude and micro (less than 2,0), tiny (2,0-2,9), little (3,0-3,9), light (4,0-4,9), moderate (5,0-5,9), strong (6,0-6,9), great (7,0-7,9), important (8,0-8,9), exceptional (9,0-9,9) and extreme (superior a 10).
The Office points out that the location of the epicenter of an earthquake “is a physical process and complex mathematical depending on the data set, algorithms and models of propagation of seismic waves”, Remembering that “different agencies can produce slightly different results”.
“In the same way, the preliminary determinations are usually subsequently corrected, by integrating more information”, he added.
