2023-02-06, M7.8, M7.5, Turkey

On the 6th of February 2023 at 01:17:35 (UTC) an M7.8 earthquake occurred in South-Eastern Turkey (see map below). The event effected Turkey, Syria and surrounding areas. The earthquake struck 30 km WNW of Gaziantep, Turkey and 108 km NNW of Aleppo, Syria, both of which are densely populated areas. Several strong aftershocks have also been observed in the region, notably a magnitude M7.5 about 100km north of Gaziantep at 10:24:49 (UTC) the same day. Over five thousand deaths and many injured, largely due to building collapse, have been reported. The M7.8 and M7.5 earthquakes occurred at depths of 18km and 10km respectively. Such large, shallow earthquakes produce significant ground shaking.

For a radio interview on RTE Radio 1 titled “Why is Turkey so prone to earthquakes?” with Chris Bean, Head of Geophysics at DIAS follow this link: https://www.rte.ie/radio/radio1/clips/22208567/

Chris Bean also talked on The Pat Kenny Show on Newstalk radio, the clip can be accessed here: https://www.insn.ie/wp-content/uploads/2023/02/The-Paty-Kenny-Show-7th-Feb-2023-Chris-Bean.mp3

The event was recorded by seismic stations worldwide, including stations in the Irish National Seismic Network (INSN), see figure below.

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).
