Tectonic setting
The ongoing continental collision between the
strike-slip faulting. Large earthquakes with magnitudes of up to 7.5 have occurred in the region with an average recurrence interval of 15 years. These earthquakes correspond to reverse faulting at a depth of 170 to 280 km.[1] These earthquakes rather than occurring at a plate boundary, are sourced from within the Indian Plate as it dives beneath the Hindu Kush. As the tectonic slab of the Indian Plate descends at a near-vertical angle into the mantle, it stretches and begins to "tear", eventually leading to a slab detachment.[2] This action results in stress accommodation along faults that produces earthquakes when ruptured
.
Earthquake
This was a relatively deep shock with a reverse focal mechanism.[3] The quake was widely felt in both Pakistan and Afghanistan, it was felt in areas such as Karachi, Kabul and Islamabad.[4]
Casualties
Landslides killed three people and two others suffered fatal heart attacks in Mirpur, Pakistan.[3]
