KHUZDAR, Pakistan / AsiaWire.IO / – On Saturday, October 17, a 5.6 magnitude earthquake struck Pakistan’s Balochistan province, with its epicenter near the city of Khuzdar. The German Research Centre for Geosciences reported the seismic event, noting it occurred at a depth of 10 kilometres, equivalent to 6 miles. Earthquakes at such shallow depths are typically associated with more intense ground shaking compared to deeper ones of similar magnitude. Initial reports did not specify any casualties or damage resulting from the tremor.
Based in Potsdam, Germany, the GFZ provides rapid estimations of significant seismic activity worldwide. Its preliminary readings for magnitude and depth are subject to updates as additional seismic data becomes available. The figures released on Saturday formed the basis of early reports concerning the event. Khuzdar, situated in central Balochistan, is the largest province in Pakistan by area. At this stage, authorities had yet to release detailed information regarding the quake’s impact in initial reports.
Balochistan lies within a seismically active zone on 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 geological structures such as the Chaman Fault, a left-lateral strike-slip fault, and the Sulaiman fold and thrust belt. Tension along these fault lines has historically generated some of the deadliest earthquakes in Pakistan’s history.
Fault systems increase Balochistan’s vulnerability to powerful quakes
The 1935 Quetta earthquake, which measured 7.7, resulted in an estimated 30,000 to 60,000 fatalities. A decade later, an 8.1 magnitude quake off the Makran coast caused a tsunami that claimed approximately 4,000 lives. The 2008 Ziarat earthquake, registering 6.4, left 215 people dead. In 2013, a magnitude 7.7 quake centered in Awaran District, adjacent to Khuzdar, caused 825 deaths and injured around 700 individuals.
Another tragic event occurred on October 7, 2021, when a 5.9 magnitude earthquake struck Harnai District. Hitting early in the morning, the quake resulted in at least 42 deaths, many of whom were women and children. The disaster injured approximately 300 people and destroyed about 10,000 mud homes. Satellite imagery revealed over 100 landslides triggered by the quake, blocking roads and hampering rescue efforts.
Recent seismic activity underscores ongoing earthquake risks
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 shook parts of Pakistan. Balochistan and Khyber Pakhtunkhwa lie on the Eurasian plate, whereas Sindh and Punjab rest on the Indian plate. This tectonic positioning exposes the country to earthquakes originating from its northern mountain ranges extending to the southwestern coastline.
Moderate earthquakes ranging from 5 to 6 magnitudes can cause damage to vulnerable structures near the epicenter. Shallow seismic events are often followed by aftershocks, as observed after the 2021 Harnai quake, which experienced aftershocks of magnitude 4.6 and 4.5. Initial reports from Saturday’s earthquake did not mention any aftershocks, but more details are anticipated as local authorities evaluate conditions around Khuzdar.
