Increased activity has been observed since Wednesday afternoon, when a number of weaker earthquakes occurred. The three strongest appeared around half past two, the foci were located near the village of Černá. “Some residents of nearby villages, but also of Aš, for example, felt a weak tremor and heard the typical booming sound that accompanies an earthquake,” the institute said.
Seismic activity has the character of an earthquake swarm, which is a sequence typical for the region of western Bohemia. According to experts, it cannot be ruled out that the swarm will continue for several weeks and get even stronger. However, they mentioned that there is usually no major material damage in the area.
“If you felt an earthquake, we would be happy if you could send us the information through a macroseismic questionnaire or a mobile application,” invited the Institute of Geophysics.
Chebsko is the most seismically active region in the Czech Republic. Although earthquakes are frequent here, fortunately they tend to break down into earthquake swarms, during which the pressures in the earth’s underground are released gradually after smaller shocks rather than once during a strong earthquake. The strongest earthquake in the last several decades hit Chebsko in 1985. At that time, the tremors reached a magnitude of up to 4.6 degrees. Walls were already cracking, chimneys were falling and crockery was breaking.
