KHUZDAR, Pakistan / AsiaWire.IO / – On Saturday, October 17, a magnitude 5.6 earthquake struck Pakistan’s Balochistan region, with its epicenter near the city of Khuzdar. The German Research Centre for Geosciences documented the seismic event, indicating it occurred at a depth of 10 kilometres, or 6 miles. Earthquakes at such shallow depths generally produce stronger shaking on the surface compared to deeper ones of the same magnitude. Initial reports did not specify any casualties or structural damage.
Based in Potsdam, Germany, the GFZ provides swift initial estimates of major earthquakes worldwide. Its early data on magnitude and depth are subject to updates as further seismic information becomes available. The figures from Saturday served as the primary basis for initial reports about the event. Khuzdar, situated in central Balochistan, is the largest province by area in Pakistan. Authorities had not issued detailed information regarding the quake’s impact in early 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 such as the Chaman Fault, a left-lateral strike-slip fault, and the Sulaiman fold and thrust belt. Tension along these tectonic features has historically caused some of the deadliest earthquakes in Pakistan’s history.
Fault systems increase Balochistan’s vulnerability to strong seismic events
The 1935 Quetta earthquake, which registered 7.7, resulted in an estimated 30,000 to 60,000 fatalities. A decade later, a magnitude 8.1 quake off the Makran coast triggered a tsunami that claimed roughly 4,000 lives. The 2008 Ziarat earthquake, with a magnitude of 6.4, caused 215 deaths. In 2013, a magnitude 7.7 earthquake centered in Awaran District near Khuzdar led to 825 deaths and approximately 700 injuries.
On October 7, 2021, Harnai District was struck by a magnitude 5.9 earthquake that caused the death of at least 42 people, many of whom were women and children. The quake injured around 300 individuals and destroyed approximately 10,000 mud homes. Satellite imaging revealed over 100 landslides following the event, which blocked roads and hindered rescue efforts.
Ongoing seismic activity highlights the persistent risk in the region
Pakistan experienced several significant tremors in 2026. In August, a magnitude 5.4 earthquake struck Gilgit-Baltistan near Sost, while in April, a magnitude 6.2 quake centered in Afghanistan’s Hindu Kush affected the region. Balochistan and Khyber Pakhtunkhwa are situated on the Eurasian plate, whereas Sindh and Punjab lie on the Indian plate, exposing the country to earthquakes originating from its northern mountains to the southwestern coast.
Moderate earthquakes with magnitudes between 5 and 6 can cause damage to weaker structures near the epicenter. Shallow seismic events in this area are often followed by aftershocks, as demonstrated after the 2021 Harnai earthquake, which experienced aftershocks measuring 4.6 and 4.5. Saturday’s initial reports did not mention any aftershocks, but further details are anticipated as local authorities evaluate conditions around Khuzdar.
