KHUZDAR, Pakistan / AsiaWire.IO / – A tremor measuring 5.6 on the Richter scale struck Pakistan’s Balochistan province on Saturday, October 17, with the epicenter near the city of Khuzdar. The German Research Centre for Geosciences reported the seismic event, indicating it occurred at a depth of 10 kilometres, or 6 miles. Earthquakes at such shallow depths typically produce stronger shaking on the surface than those originating deeper underground. Initial reports did not provide information regarding casualties or damages.
The GFZ, headquartered in Potsdam, Germany, specializes in providing rapid assessments of significant earthquakes worldwide. Its preliminary data on magnitude and depth are often updated as further seismic information becomes available. The figures released on Saturday served as the primary basis for early reports about the event. Khuzdar is situated in central Balochistan, the largest province in Pakistan by area. Authorities had not yet released detailed information about the quake’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 crossed by major fault systems, including the Chaman Fault, a left-lateral strike-slip fault, and the Sulaiman fold and thrust belt. The strain accumulated along these fault lines has historically caused some of the deadliest earthquakes in Pakistan’s history.
Fault zones contribute to Balochistan’s vulnerability to strong seismic events
Notable earthquakes include the 1935 Quetta quake, which registered 7.7 and 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 approximately 4,000 lives. The 2008 Ziarat earthquake, measuring 6.4, caused the deaths of 215 individuals. In 2013, a magnitude 7.7 quake centered in Awaran District, adjacent to Khuzdar, resulted in 825 deaths and about 700 injuries.
A deadly magnitude 5.9 tremor struck Harnai District on October 7, 2021, in the early hours, killing at least 42 people, many of whom were women and children. Around 300 individuals were injured, and nearly 10,000 mud homes were destroyed. Satellite mapping revealed over 100 landslides following the quake, which obstructed roads and hampered rescue operations.
Recent seismic activity emphasizes ongoing earthquake risks
In 2026, Pakistan experienced several significant tremors. A magnitude 5.4 earthquake hit Gilgit-Baltistan near Sost in August, while a magnitude 6.2 quake centered in Afghanistan’s Hindu Kush shook Pakistan in April. The country’s northern regions of Balochistan and Khyber Pakhtunkhwa rest on the Eurasian plate, whereas Sindh and Punjab lie on the Indian plate. This positioning makes Pakistan vulnerable to earthquakes originating from its northern mountain ranges to its southwestern coast.
Moderate earthquakes in the 5 to 6 magnitude range can cause damage to vulnerable structures near the epicenter. Shallow seismic events are often followed by aftershocks, as seen after the 2021 Harnai quake, which experienced aftershocks of magnitude 4.6 and 4.5. No aftershocks have been reported yet from Saturday’s earthquake, but further details will emerge as local authorities evaluate conditions around Khuzdar.
