2020-02-23, M5.7, Turkey-Iran Border Region

At 05:53:01 (UTC) a M5.7 earthquake struck 25km south-east of Sarey, Turkey close to the Iranian border. The earthquake had a depth of ~6.4km and initial reports are of several deaths and numerous injuries due to building collapse. A second M6 event occurred at 16:00:31 (20-02-23) in the same area.

 

The middle east and surrounding areas are prone to seismic activity due to the movement of four major tectonic plates (Arabian, Eurasian, Indian and African). This plate interaction produces large-scale tectonic processes such as subduction, transform faulting, compressional mountain building, and crustal extension.

2020-01-24, M6.7, Turkey

At 17:55:14 UTC on January 24th, 2020 a magnitude M6.7 earthquake struck the Kalaba-Sivrice region in Eastern Turkey, see the map below for the approximate location of the event. The earthquake had a depth between 10 and 15 km and resulted in very strong to severe ground shaking. Currently 22 fatalities and hundreds of injuries have been reported with the collapse of several buildings. The earthquake is located on or close to the East Anatolian Fault which separates the Anatolia Block of the Eurasia plate from the Arabia plate. Damaging earthquakes occurr relatively frequently in Turkey. According to the USGS seven other M6 or larger events have occurred over the preceding half century within 250 km of the January 24, 2020 earthquake. For maps showing plate boundaries and locations of past earthquakes in Turkey see https://en.wikipedia.org/wiki/List_of_earthquakes_in_Turkey.

The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).
