A powerful earthquake struck Southeast Asia on 28 March 2025, causing significant devastation in Myanmar and Thailand. The tremors led to substantial loss of life and widespread destruction of infrastructure. This article delves into the specifics of the earthquake, its causes, and its impact on the affected regions.
Overview of the Earthquake
Date and Time: 28 March 2025, approximately 12:50 PM local time.
Magnitude: 7.7 on the Moment Magnitude Scale.
Epicentre: Near Mandalay, Myanmar.
Depth: 10 kilometres (6 miles).
The shallow depth of the earthquake contributed to its severe impact on the surface.
Causes of the Earthquake
Earthquakes occur due to the movement of tectonic plates beneath the Earth’s surface. In this instance, the earthquake resulted from “strike-slip faulting” along the Sagaing Fault, a significant tectonic boundary between the Indian Plate to the west and the Eurasian Plate to the east. This movement involves the plates sliding sideways against each other.
Impact on Myanmar
Casualties: At least 144 people confirmed dead, with thousands injured.
Infrastructure Damage:
Collapse of multiple buildings and bridges.
Significant damage to roads, leading to transportation disruptions.
Historic sites, including parts of the Mandalay Palace, suffered considerable harm.
The ongoing civil conflict in Myanmar has further complicated rescue and relief efforts.
Impact on Thailand
Casualties: At least five fatalities reported in Bangkok.
Infrastructure Damage:
Collapse of a tower block under construction, resulting in deaths and numerous individuals missing.
Structural damage to various buildings across the city.
The tremors caused widespread pawith residents evacuating buildings and seeking safety outdoors.
Understanding Earthquake Magnitude
The magnitude of an earthquake quantifies the energy released during the event. A 7.7 magnitude earthquake is classified as a major event, capable of causing serious damage in areas several tens of miles across. The shallow depth of this earthquake amplified its destructive potential, as seismic waves lose less energy before reaching the surface.
Aftershocks and Future Risks
Following significant earthquakes, aftershocks are common. These are smaller tremors that occur as the Earth’s crust adjusts to the new stress distribution. Aftershocks can persist for days to weeks and may cause additional damage, particularly to already weakened structures. Residents in affected areas are advised to remain vigilant and adhere to safety guidelines issued by local authorities.
Challenges in Prediction
Despite advancements in seismology, precise prediction of earthquakes remains beyond current scientific capabilities. However, regions with known seismic activity, such as the Sagaing Fault, are identified as higher risk areas. Continuous monitoring and preparedness are essential to mitigate the impact of potential future events.
Conclusion
The 28 March 2025 earthquake has had a profound impact on Myanmar and Thailand, underscoring the devastating power of natural seismic events. As rescue and recovery operations continue, the resilience and solidarity of the affected communities remain paramount. This tragedy highlights the critical importance of preparedness and robust infrastructure in earthquake-prone regions.
