KHUZDAR, Pakistan / AsiaWire.IO / – On Saturday, October 17, a magnitude 5.6 earthquake struck Pakistan’s Balochistan province, with the epicenter close to 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 ground shaking compared to deeper ones of similar magnitude. Initial reports did not specify any casualties or damage.
Based in Potsdam, Germany, the GFZ offers quick estimates of major earthquakes worldwide. Its early measurements of magnitude and depth may be updated as additional seismic information becomes available. The figures from Saturday served as the primary data for early reports on the event. Khuzdar is situated in central Balochistan, the largest province in Pakistan by area. Authorities had not released detailed information regarding the quake’s impact in initial statements.
Balochistan is located in 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. Significant fault systems, including the Chaman Fault, a left-lateral strike-slip fault, and the Sulaiman fold and thrust belt, traverse this region. Tectonic stress along these features has historically triggered some of Pakistan’s most devastating earthquakes.
Fault lines contribute to Balochistan’s vulnerability to strong seismic events
The 1935 Quetta earthquake, measuring 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 caused approximately 4,000 deaths. The 2008 Ziarat earthquake, with a magnitude of 6.4, led to 215 fatalities. In 2013, a magnitude 7.7 quake centered in Awaran District, near Khuzdar, claimed 825 lives and injured about 700.
On October 7, 2021, a powerful magnitude 5.9 earthquake struck Harnai District, causing at least 42 deaths, many of whom were women and children. Around 300 people were injured, and approximately 10,000 mud homes were destroyed. Satellite imagery revealed more than 100 landslides following the quake, blocking roads and hampering rescue efforts.
Recent seismic activity emphasizes ongoing earthquake risk
In 2026, Pakistan experienced several significant tremors. In August, a magnitude 5.4 earthquake struck Gilgit-Baltistan near Sost, and in April, a 6.2 magnitude quake centered in Afghanistan’s Hindu Kush shook the region. Balochistan and Khyber Pakhtunkhwa rest on the Eurasian plate, while Sindh and Punjab are situated on the Indian plate. This positioning exposes the entire country to earthquakes originating from its northern mountains to the southwestern coast.
Moderate earthquakes in the 5 to 6 magnitude range can cause damage to vulnerable structures near the epicenter. Such shallow events are often followed by aftershocks, as observed 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. Further details are anticipated as local authorities evaluate the situation around Khuzdar.
