The Vogtland is one of the most earthquake-active regions in Germany. It has been rumbling underground almost continuously for two days. The floor vibrates and there is a crack in the roof, residents say.
A swarmquake now causes the earth in Vogtland. On Sunday alone, the specialized portal “Earthquake News” registered more than three dozen quakes in the southwest region of Saxony.
The first rumbling was recorded on Friday before 5:00 am, too weak to feel. This was followed by nine more shocks towards evening, the “strongest” with a magnitude of 2.0 on the Richter scale and an intensity of II on the European Macroseismic scale (EMS), which some people may have felt by definition.
Since then, the earth in the border area with the Czech Republic has not come to rest. On Saturday, 39 vibrations of magnitude 1 and higher were detected by late evening. 13 of them had an intensity of II and could therefore be noticed by a few people. 3 even fell to level three, which means that people inside buildings may have felt a sway or slight vibration.
“Like a truck thundering by”
And in fact, numerous users on “earthquake news” report rumblings, bumps and cracks in the roof structure. A user from Markneukirchen, who claims to live on the ground floor of a house, describes: “Like a truck thundering past, only without engine noise, rumbling and vibrating in the ground.” Another reports: “We are in the attic, just wrapped presents. Even here the roof creaked a lot.”
The Vogtland is one of the most active regions in Germany when it comes to earthquakes. Swarm tremors like the current one occur here over and over and often last for weeks or months. But rarely does the earth shake so badly that it wreaks havoc.
The strongest earthquake in the recent past nevertheless caused people to leave their homes for fear in late May 2014. On the Czech side, shocks with a strength of 4.2 to 4.6 caused chimneys to collapse and walls to crack. The Saxon side got out slightly: no damage was reported to the fire brigade at the time.
