GILGIT-BALTISTAN / RankWire.AI / – On Thursday morning, a magnitude 5.4 earthquake struck northeastern Pakistan, producing powerful tremors that were felt in various parts of Gilgit-Baltistan. While Pakistan’s official seismic authorities recorded the quake at magnitude 5.3, the event’s epicenter was situated approximately 27 kilometers northwest of Sost, in the vicinity of the Khunjerab area, at a depth of 15 kilometers according to the Pakistan Meteorological Department. The early morning shaking, which occurred at 5:35 a.m. local time on August 13, was experienced by residents across multiple northern communities, with the tremors notably impacting the region’s landscape and infrastructure.
The seismic activity was particularly felt in the districts of Hunza and Nagar, with Chipurson Valley in Upper Hunza showing some of the most distinct ground effects. As the tremors rattled communities nestled among steep mountain slopes, inhabitants evacuated their homes amid reports of landslides and falling rocks that followed in parts of the valley. A rockfall obstructed the Chipurson Valley road near Ramanji, disrupting local transportation; this route is crucial for connecting remote settlements in an area where mountain roads serve as vital links between villages and larger population centers.
Initial assessments from authorities indicated there were no fatalities or injuries resulting from the main quake, and no confirmed structural damage was reported at that stage. However, landslides and rockfalls continued to be the primary documented impacts on local infrastructure. After the shaking, officials from the Gilgit-Baltistan administration closely monitored the affected areas and assessed road conditions, especially in zones where debris had compromised mountain routes. This seismic event marked another significant earthquake in a region of northern Pakistan that has experienced frequent tremors throughout 2026.
Rockfalls Impede Roadways in Upper Hunza
The earthquake’s epicenter was located near Sost, a town situated along the Karakoram Highway corridor in northern Pakistan, south of the Khunjerab Pass, which connects the region to other parts of the country. Sost serves numerous communities in Upper Hunza and is a gateway for travelers crossing into China’s Xinjiang region via a high-altitude border crossing. The mountainous terrain surrounding much of the district makes the roads highly susceptible to rockfalls and landslides, especially during seismic events like Thursday’s quake, which caused noticeable shaking in this remote area, predominantly affecting communities closest to the epicenter.
Later that same morning, a second earthquake struck the same general region, according to official seismic data that recorded the tremor at 9:24 a.m. local time. This subsequent quake measured magnitude 4.7 with a depth of 19 kilometers, with its epicenter approximately 28 kilometers west-northwest of Sost. The proximity of this second event to the initial quake indicates a continued period of seismic activity in Upper Hunza and nearby districts, with both tremors occurring within roughly four hours of each other.
Repeated Seismic Movements Mark Northern Pakistan’s Tectonic Volatility
Earlier this year, the region experienced a more powerful earthquake, measuring magnitude 5.8, which struck on January 19 and affected areas including Hunza, Ghizer, and other parts of Gilgit-Baltistan. That event resulted in landslides, structural damages, road blockages, and even one fatality, with several injuries reported. Chipurson Valley, in particular, suffered damage to homes and local infrastructure, and the ensuing road closures complicated access to isolated settlements, hampering rescue and relief efforts.
The northern mountain belt of Pakistan forms part of an active seismic zone influenced by major tectonic plate movements, leading to regular earthquake activity affecting Gilgit-Baltistan, Kashmir, and neighboring regions of northern Pakistan and Afghanistan. The August 13 tremor, centered near Sost, once again brought intense shaking to communities in Upper Hunza, with landslides and rockfalls disrupting transportation, although authorities confirmed no casualties from the primary event. Records also show that another significant earthquake occurred near Sost later on the same morning, emphasizing the persistent seismic risk in this tectonically active zone.
