Nepal experienced two earthquakes within a few hours on Wednesday, September 16, adding to concerns in a country that is still dealing with the aftermath of a devastating flood disaster. The earthquakes were recorded in the northwestern Mugu district, where authorities reported no immediate casualties or significant property damage following the tremors.
According to Nepal’s National Earthquake Monitoring and Research Center, the first earthquake occurred at 1:51 am local time and measured 4.5 in magnitude. A second earthquake followed at 4:28 am and measured 4.2. Both earthquakes were recorded with their epicentres around Kalai in Mugu district.
India’s National Centre for Seismology also detected the two earthquakes. Its readings placed the first tremor at a depth of about 81 kilometres and the second at a depth of about 98 kilometres. The NCS recorded the second earthquake at magnitude 4.0, showing a slight difference in measurement from Nepal’s earthquake monitoring agency.
The tremors were also felt in nearby areas, including Dolpa and Jumla districts, according to reports. However, there were no immediate reports of deaths, injuries or structural damage. Authorities and monitoring agencies continue to observe the situation for any further seismic activity or reports of damage.
The latest earthquakes come at a sensitive time for Nepal, which is recovering from a major flood disaster that struck the country weeks earlier. The August 26 disaster was linked to a glacial collapse near the Nepal Tibet border and resulted in extensive flooding, destruction of infrastructure and a large number of casualties and missing people.
Reuters reported on September 15 that more than 5,130 people remained missing on the Nepalese side of the disaster area, while 1,386 deaths had been confirmed. The flooding caused widespread destruction, including damage to roads, homes and hydropower infrastructure. Search and recovery operations have continued to face difficult conditions in affected areas.
The flood disaster has also created significant challenges for Nepal’s infrastructure and economy. Roads and bridges were damaged, communication links were disrupted and several hydropower facilities were affected. The scale of the destruction has increased the need for reconstruction and recovery assistance.
India has also taken steps to support Nepal’s recovery from the flood-related power disruption. India approved Nepal’s request for additional electricity imports after flooding damaged hydropower infrastructure. The arrangement allows Nepal to receive up to 654 megawatts of electricity for 18 hours a day between September 13 and December 31, 2026.
The occurrence of the latest earthquakes does not mean that the floods and earthquakes are directly connected. The earthquakes were separate seismic events recorded in Mugu district. There is currently no reported evidence establishing that the recent flood disaster caused these earthquakes.
Nepal is located in a seismically active region because it lies along the collision zone between the Indian and Eurasian tectonic plates. As a result, earthquakes occur regularly across different parts of the country. The Himalayan region is particularly vulnerable to seismic activity, making monitoring and preparedness important for communities in mountainous areas.
The latest tremors were relatively moderate, and authorities have not reported major consequences from either earthquake so far. However, monitoring agencies typically continue to track earthquake activity following multiple tremors in a short period.
The two earthquakes also follow seismic activity earlier this month. Reports said a magnitude 5.3 earthquake struck Nepal’s Mustang district on September 8, followed by a magnitude 4.0 tremor in the same district on September 9. The latest activity in Mugu therefore adds to a series of earthquakes recorded in Nepal during September.
For residents in affected areas, the immediate focus remains on monitoring official updates and checking buildings and infrastructure for any signs of damage. In mountainous regions, earthquake activity can also raise concerns about landslides and other secondary hazards, although no such major impact has been reported following Wednesday’s tremors.
Authorities have so far not reported casualties or significant property damage from the two Mugu earthquakes. Further assessments may provide additional information if any damage is identified after the initial reports.
The latest developments highlight the multiple natural disaster challenges Nepal is facing. While communities continue to recover from the devastating August floods, the country has now experienced two moderate earthquakes within a short period. Government agencies and seismic monitoring centres are expected to continue tracking activity and providing updates as necessary.
