Magnitude 4.5 Earthquake Strikes Myanmar, NCS Confirms Details
An earthquake with a magnitude of 4.5 struck Myanmar on Friday, July 11, 2025, according to an official statement released by the National Center for Seismology (NCS). The seismic event occurred at a depth of 101 kilometers, as detailed in a post on the social media platform X by the NCS.
Specifics of the Recent Seismic Activity
The NCS provided precise coordinates for the earthquake, noting it occurred at latitude 25.76 N and longitude 95.26 E. The timing was recorded at 05:56:04 IST. This event is part of a series of tremors that have affected the region in recent days, underscoring Myanmar's vulnerability to geological hazards.
Recent Earthquake History in Myanmar
Earlier in the week, on July 7, 2025, a magnitude 4.6 earthquake jolted the area. The NCS reported this event at a depth of 85 km, with coordinates at latitude 24.78 N and longitude 94.85 E. Prior to that, on July 3, 2025, a magnitude 4.1 earthquake struck at a much shallower depth of 10 km, making it more susceptible to aftershocks and potential damage due to stronger ground shaking.
Geological Context and Risks
Myanmar is prone to moderate and large magnitude earthquakes, with significant risks along its coastline for tsunamis. The Sagaing Fault elevates seismic hazards for key regions, including Sagaing, Mandalay, Bago, and Yangon, which collectively represent 46 percent of the country's population. Although Yangon is relatively distant from the fault trace, its dense population makes it particularly vulnerable to earthquake-related impacts.
Historical Precedents: In 1903, a powerful magnitude 7.0 earthquake in Bago also affected Yangon, demonstrating the far-reaching consequences of seismic events in this region.
Health and Safety Implications
Following major earthquakes, such as the magnitude 7.7 and 6.4 events that struck central Myanmar on March 28, the World Health Organization (WHO) has warned of escalating health threats. Displaced populations face increased risks of tuberculosis, HIV, and vector- and water-borne diseases, highlighting the need for robust emergency response and public health measures.
Shallow earthquakes, like the recent magnitude 4.1 event, are generally more dangerous than deep ones because seismic waves travel a shorter distance to the surface, resulting in intensified ground shaking and greater potential for structural damage and casualties.
This report is based on information from the National Center for Seismology and aims to provide a comprehensive overview of the recent seismic activity in Myanmar, emphasizing the ongoing geological and humanitarian challenges faced by the region.
