KHUZDAR, Pakistan / AsiaWire.IO / – On Saturday, October 17, an earthquake measuring 5.6 in magnitude struck Pakistan’s Balochistan province, with its epicenter near Khuzdar. The German Research Centre for Geosciences reported the seismic event, stating it occurred at a depth of 10 kilometers, or 6 miles. Earthquakes at such shallow depths typically result in more intense ground shaking compared to deeper ones of similar magnitude. Initial reports did not provide information regarding casualties or structural damage.
Headquartered in Potsdam, Germany, GFZ offers prompt estimations of major earthquakes worldwide. Its preliminary data on magnitude and depth may be revised as further seismic information is analyzed. The figures released on Saturday formed the basis for early reports about the event. Khuzdar is situated in central Balochistan, which is Pakistan’s largest province by land area. Authorities had yet to release detailed assessments of the earthquake’s impact in initial reports.
Balochistan lies within a seismically active zone along the southern boundary of the Eurasian plate. The Indian plate converges obliquely with the Eurasian plate along Pakistan’s western edge. The region is traversed by major fault systems like the Chaman Fault, a left-lateral strike-slip fault, and the Sulaiman fold and thrust belt. Tension along these tectonic features has historically triggered some of the deadliest earthquakes in Pakistan.
Fault line activity heightens Balochistan’s earthquake vulnerability
The 1935 Quetta earthquake, which registered 7.7, resulted in approximately 30,000 to 60,000 fatalities. A decade later, an 8.1 magnitude quake off the Makran coast caused a tsunami that claimed around 4,000 lives. The 2008 Ziarat quake, with a magnitude of 6.4, resulted in 215 deaths. In 2013, a magnitude 7.7 earthquake centered in Awaran District, adjacent to Khuzdar, led to 825 deaths and roughly 700 injuries.
A significant magnitude 5.9 earthquake also struck Harnai District on October 7, 2021. Occurring early in the morning, this tremor resulted in at least 42 fatalities, many women and children among the victims. Approximately 300 individuals were injured, and around 10,000 mud homes were destroyed. Satellite imagery revealed over 100 landslides following the quake, which obstructed roads and hindered rescue operations.
Ongoing seismic activity underscores ongoing risk
Pakistan experienced several notable tremors in 2026. In August, a magnitude 5.4 quake struck Gilgit-Baltistan near Sost. Additionally, in April, a magnitude 6.2 earthquake centered in Afghanistan’s Hindu Kush affected Pakistan. Balochistan and Khyber Pakhtunkhwa are positioned on the Eurasian plate, whereas Sindh and Punjab lie on the Indian plate. This geological setting exposes the nation to earthquakes originating from its northern mountain ranges to the southwestern coast.
Moderate earthquakes, with magnitudes between 5 and 6, can cause significant damage to vulnerable structures near the epicenter. Shallow seismic events often trigger aftershocks, as demonstrated after the 2021 Harnai quake, which experienced aftershocks of magnitude 4.6 and 4.5. The initial reports from Saturday’s earthquake did not mention any aftershocks. More comprehensive information is anticipated as local authorities evaluate the situation around Khuzdar.
