Chinanews.com, Chengdu, February 7th (Reporter He Shaoqing) The reporter learned from the State Key Laboratory of Geological Disaster Prevention and Geoenvironmental Protection of Chengdu University of Technology (referred to as "Chengli State Key Laboratory of Geological Disasters") on the 7th that after the earthquake in Turkey , the laboratory strong earthquake geological hazard research team used the previously developed earthquake-induced landslide prediction model to predict landslides induced by earthquake swarms in Turkey: the landslide-prone areas are mainly distributed along the East Anatolia fault zone.
On February 6 local time, two 7.8-magnitude earthquakes occurred in Turkey.
During the period between the two major earthquakes, several earthquakes with magnitudes above 5.0 occurred in this area, forming earthquake swarms.
When the earthquake occurred, many countries on the three continents of Asia, Europe and Africa were strongly felt.
The main epicenters of the earthquake swarm were located near the East Anatolia fault.
It is one of the main intracontinental transformation faults in the Eastern Mediterranean region. Together with the North Anatolian dextral fault zone, it accommodates the westward compressional tectonic movement of the Anatolian plate. To the dive action control.
The East Anatolian fault zone has experienced a series of large earthquakes over the past two centuries, accompanied by significant surface rupture.
The earthquake-induced landslide prediction model of Chengli National Key Laboratory of Earthquakes uses the global co-seismic landslide database and artificial intelligence algorithm to realize the rapid prediction of the spatial distribution probability of strong earthquake-induced landslides.
Prediction results show that landslide-prone areas induced by Turkish earthquake swarms are distributed continuously in the Eastern Anatolia Mountains.
The Anatolian plate on the west is more undulating than the Arabian plate, and correspondingly has a higher susceptibility to landslides.
Aleppo, Gaziantep, and Antakya, where the population density is the most concentrated in the earthquake-stricken areas, are located at a certain distance from the main body of the mountain range, and are located in the medium-low prone area where the threat of landslide hazards is small.
However, due to the poor earthquake resistance of Turkish buildings, they still face the problem of house collapse and damage.
Several densely populated towns along the side of the mountain range are located in the medium-high susceptible zone.
There is a greater threat of landslides and collapses in the area adjacent to the mountain.
Kahramanmaras is located in the Eastern Anatolian Mountains, and the mountains on both sides are located in the middle-high risk-prone area. It is facing a more serious threat of landslide disaster risk. Attention should be paid to the impact of secondary geological disasters after the earthquake .
According to Fan Xuanmei, deputy director of the Chengli Earthquake Research Laboratory, at present, there is still the possibility of strong earthquakes in the local area.
The laboratory has sent the prediction results to its counterparts in Turkey, and Turkish disaster investigators are rushing to the scene.
