KHUZDAR, Pakistan / AsiaWire.IO / – A tremor measuring 5.6 on the Richter scale struck Pakistan’s Balochistan province on Saturday, October 17, with its epicenter near Khuzdar. The German Research Centre for Geosciences documented the quake, indicating it occurred at a depth of 10 kilometers, or 6 miles. Such shallow earthquakes tend to produce more intense ground shaking compared to deeper ones of similar magnitude. Early reports did not provide information about casualties or damages.
Based in Potsdam, Germany, the GFZ offers swift estimates of major seismic events worldwide. Its initial data on magnitude and depth are subject to updates as more seismic information becomes available. The figures reported on Saturday served as the primary basis for early accounts of the event. Khuzdar lies in central Balochistan, which is the largest province in Pakistan by area. Authorities had yet to release detailed reports on the quake’s impact in initial statements.
Balochistan is situated in a seismically active zone along the southern edge of the Eurasian plate. The Indian plate converges obliquely with the Eurasian plate along Pakistan’s western boundary. Prominent fault systems such as the Chaman Fault, a left-lateral strike-slip fault, and the Sulaiman fold and thrust belt traverse the region. Tension along these structures has historically caused some of Pakistan’s deadliest earthquakes.
Fault systems contribute to Balochistan’s vulnerability to strong seismic events
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 generated a tsunami that claimed about 4,000 lives. The 2008 Ziarat quake, with a magnitude of 6.4, left 215 people dead. In 2013, a magnitude 7.7 earthquake centered in Awaran District, adjacent to Khuzdar, caused 825 deaths and injured roughly 700.
On October 7, 2021, a destructive magnitude 5.9 earthquake struck Harnai District in the early hours, killing at least 42 individuals, many of whom were women and children. Approximately 300 people were injured, and about 10,000 mud homes were destroyed. Satellite imagery revealed over 100 landslides following the quake, blocking roads and hindering rescue efforts.
Recent seismic activity highlights ongoing seismic hazard 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 6.2 magnitude quake centered in Afghanistan’s Hindu Kush shook the country. The northern regions of Balochistan and Khyber Pakhtunkhwa rest on the Eurasian plate, whereas Sindh and Punjab are on the Indian plate. This positioning makes Pakistan vulnerable to earthquakes originating from its northern mountains extending to its southwestern coastline.
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 demonstrated after the 2021 Harnai earthquake, which experienced aftershocks of magnitude 4.6 and 4.5. Initial reports from Saturday’s quake did not mention any aftershocks, but further details are anticipated as local authorities evaluate conditions around Khuzdar.
