An earthquake measuring 4.9 on the Richter scale shook the eastern Aegean Island of Samos on Saturday morning. The quake was recorded at 7.19 a.m. (05.19 GMT), with an epicenter some 25 kilometers northeast of the harbor of Vathi, Samos, near the Asia Minor coast.

The tremor’s depth was measured at 12.9 kilometers.

An afterquake of 3.6 on the Richter scale later shook the same region at 13.54 (11.54 GMT), and from nearly the exact same location at the stronger quake: 25 kilometers northeast of Vathi and at a depth of 12.9 kilometers.

Speaking on television hours later, the president of Greece’s Organization for Seismic Planning and Protection (OASP), Prof. Efthymios Lekkas, said he believes the quake is a remnant of a major tremor that erupted in 2017, “it’s not related to the rift that caused the major quake”.
