Seismologists in Greece are on alert after the recent high frequency of earthquake activity in Crete. Only in the last 6 days, 101 small and medium-sized seismic vibrations were recorded, which have troubled scientists as they are still unable to determine whether the series of tremors is a pre-seismic activity of a larger quake yet to strike, or a simple cluster of vibrations.

An earthquake measuring 4.8 on the Richter scale was recorded at 05:05 on Thursday on eastern Crete.

An earthquake measuring 5.3 on the Richter scale was recorded at 23:58 on Tuesday in the sea region 40 klm west-north west of Kassos island.
