A series of more than 50 earthquakes, the most powerful of which turned out to be a shock of 5.7 (5.7) on the Richter scale, took place on the so-called. “outer Greek arc” *.
The main shock with a magnitude of 5.4 (5.7 according to the USGS) occurred on August 1 at 7:31 am in the offshore area, near the islands of Tilos and Nisyros. It was followed by a series of aftershocks up to 4.6 on the Richter scale.
Underground activity continues to this day. At 13:00 on August 2, there were more than 50 tremors. The latter was recorded at 11:55, its magnitude was 3.4 points. Apparently, active seismic activity will continue for at least several more days.
No casualties or destruction were recorded. All modern buildings on the nearby islands are designed for tremors up to 8 points, which is hundreds of times more than yesterday’s 5.7 points.
* Greek arc
Greece and specifically the “Greek Arc” is located in an area that is highly vulnerable to seismic activity and has historically always been exposed to the impact of the underground elements. The first historically recorded earthquake in Rhodes was an earthquake 226 BC… It is famous for destroying a large statue of the Colossus of Rhodes. After the earthquake, the statue lay in place for nearly eight centuries before being sold by the invaders.
In total, there are 19 active tectonic faults on the territory of Greece in the Aegean Sea, which can cause an earthquake with a magnitude of more than 7 on the Richter scale.
