Gerasimos Houliaras, Director of Research at the Geodynamic Institute of Athens, spoke on ERT about the intense seismic activity that has recently been observed in Greece.
“The earthquakes on Nisyros are tectonic in nature. The sequence dates back to last year on a tectonic fault. The largest earthquake in the series is June, with a magnitude of 5.7. Yesterday’s earthquake with a magnitude of 4.4 on the Richter scale alarmed residents because it happened at night. three tremors were recorded, ”said Mr. Hliaras.
Four seismically active regions of Greece
“At the moment, we have four sources that are acting by causing small earthquakes over many months. As a result, residents suffer from minor earthquakes in the area of Nisyros, Thebes, Crete and in the area of Nafpaktos, Aegio.
Fortunately, the strongest earthquake we have had this year in Samos made us breathe a sigh of relief, because there we expected successive earthquakes of magnitude 5 on the Richter scale, ”said the director of research at the Geodynamic Institute of Athens.
Mr. Houliaras reassured the people of Greece about the continued seismic activity in Thebes:
“Then it just caught our attention. It is not necessary to link all events throughout the territory, because every day in 30-40 parts of the country we record earthquakes. These phenomena do not bother. There is regular seismicity. The problem that exists at the moment is a seismic fault. Crete “.
As the seismologist pointed out, “after a strong vibration, the situation will decline. Day by day, gradually, the number of earthquakes will decrease. Somewhere there will be an earthquake of magnitude 4 and 5. However, the problem is in the seismic resistance of buildings. Small fluctuations will put additional stress on them, which raises concerns. This is a huge problem. “
