2023-10-07, M6.3, Afghanistan

On the 7th of October 2023 at 07:12:50 UTC an M6.3 earthquake occurred in Afghanistan at a depth of 10km (see map below for the earthquake epicentre, marked with a red circle). The earthquake struck in western Afghanistan near the city of Herat, close the Iranian border. Media reports estimate hundreds of deaths and thousands of causalities with rescue efforts still ongoing.

Afghanistan and the Middle East are prone to earthquakes due to the interaction of several large tectonic plates (Arabia, Eurasia, India and Africa). These interactions result the region experiencing several major geological processes such as subduction, faulting, mountain formation and stretching of the Earth’s crust.

The M6.3 earthquake was recorded by seismic stations operated by DIAS in the Irish National Seismic Network (INSN), see figure below.

2023-03-21, M6.5, Afghanistan

On the 21st of March 2023 a M6.5 earthquake occurred in the Hindu Kush region of Afghanistan (see map below). The earthquake occurred at 16:47:24 UTC (21:17:24 local time) an occurred at a depth of 193 km. At least 13 people died (at the time of writing), with reports of damaged buildings and landslides in northern Afghanistan and Pakistan as a result of the earthquake. Seismicity in this region is largely due to the continental collision of the India and Eurasia plates, with several major earthquakes (>M7) occurring regularly.

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