Al-Jazeera – Ali Bilal:
Director of the National Center for Seismology and Pollenology at the Saudi Geological Survey Dr. Hani Zahran said that the Authority is adding two new seismic monitoring stations in the current seismic area and two acceleration stations in the region, 25 kilometers east of the city of Amlai, Dimensional seismic velocity using a number of different techniques to determine the thickness distribution of the crust and the geological structures and to identify the seismic hazards while continuing to monitor the thermal activity and the basic and salinity of the groundwater in this region, seismic waves, surviving frequencies and shear velocities to a depth of 30 meters, Seismic and accurate seismic mapping Seismic hazard kit for the area.
Dr. Zahern said during the trip to the earthquake center, located about 25 kilometers southeast of the city of Amlag, that the cause of earthquakes in the area is the presence of cracks with a vertical offset following the system of cracks of the Red Sea, called cracks at the foot The mountain; Tectonic "cancerous" processes in the area associated with the movement of the Arab plate, in addition to the presence of a crack in a northeast-southwest direction in the area, intersect with the modern cracks.
Dr. Zahran explained that seismic activity in maps in this area in recent years and 2007 has shown that seismic activity extends over time from the first seismic sites in the arid free zone in 2007 and 2009 to the free zone. It is very shallow and the water temperature is high relative to the surrounding areas, and its interpretation is affected by these faults.
Dr. Zahern expected the continued local seismic activity in the near future weakly, without creating a danger to the surrounding areas: the number of earthquakes observed to date amounted to 129 earthquakes, the highest on the Richter scale 3.7, stressing at the same time the need to apply building codes resistant to vibration land.
