Analysis of the characteristics of the earthquake in Spain.. / May 19, 2011 /

The strongest earthquake in a half century occurred on May 11 2011. in Spain. Its magnitude was 5.1. Focal depth of 1 km. There are casualties (10 people), dozens of victims, many of destruction. The most affected city of Lorca in the south-east of the country. Many old buildings are destroyed.

In accordance with the concept and algorithm analysis seismic tectogenesis signs earthquake experts NTs OMZ analysis of this earthquake. Most informative were cloudy seismotectonic indicator detected satellite imagery 26, 27 April and 10, May 11, 2011. Images are presented in Annex 1, 2, 3. A characteristic feature of the identified cloud seismotectonic indicator was their squareshape form (Annex 1,3). Model for the formation of such cloud structures built Ph.D. Natyaganova VL (Moscow State University. Lomonosov, Department of Gas and Wave Dynamics). Side of the square was 160-190 km, which gave the potential magnitude of 5,1-5,2 (± 0,2). The actual event was a magnitude 5.1. Event date determined by the geomagnetic disturbances on April 20 and May 2 with a possible implementation of a seismic event in April or May 11 ± 2 days. Real earthquake occurred on May 11. The place of the event got a 7-degree zone P1, 2 (Annex 1,2,3).

It should be noted Seismomagnetic meridian (-15/165 ° C) of 20 April, along with the earthquake in Spain launched a major earthquake on about. Loyalty May 10 with a magnitude of 6.8 and a series of smaller events along Seismomagnetic meridian.

Thus, for the seismotectonic zones of Spain received the reference cloud signs of earthquake preparation. The efficiency of the developed techniques for the zone.
