On 28 March 2025, a magnitude 7.7 earthquake ripped through central Myanmar, producing one of the most violent and destructive seismic events in the country’s modern history. Striking at a shallow depth of just 10 kilometers, the quake unleashed supershear rupture along the Sagaing Fault and propagated across 460 kilometers of heavily populated terrain. While satellite imagery and on-the-ground surveys have documented the extensive damage—collapsed buildings, shattered infrastructure and thousands of fatalities—a newly released security-camera video from GP Energy Myanmar’s Thapyay Wa solar facility provides an unprecedented, real-time view of Earth’s crust literally splitting and sliding apart.
Background: Seismic Setting and Impact of the 2025 Myanmar Quake
Tectonic Context of the Sagaing Fault
Myanmar lies at the crossroads of several tectonic plates, making it a hotbed of seismic activity. The north–south–trending Sagaing Fault, a right-lateral strike-slip fault over 1,400 kilometers long, marks the boundary between the Burma microplate and the Sunda plate. This fault accommodates significant lateral motion—estimated at up to 18 millimeters per year—and has produced multiple large earthquakes over the past century.

The March 2025 Event: Scale and Consequences
Seismological analyses place the 28 March quake among Myanmar’s most powerful since modern instrumentation began. With a moment magnitude (Mw) of 7.7 and supershear rupture velocities exceeding the surrounding shear-wave speed, the event released intense seismic energy that lasted approximately 80 seconds. The rupture initiated near Singu in the Mandalay Region, marched southward through Sagaing Division, and terminated near Pyu in the Bago Region.
By official counts, more than 3,700 people perished and thousands more were injured. In Mandalay City alone, a UNESCO World Heritage candidate, historical pagodas and masonry structures collapsed, trapping residents beneath debris. Infrastructure from bridges to water mains cracked open, and landslides blocked key highways. Secondary impacts rippled across the region: power outages left hospitals operating on backup generators, and aftershock sequences exceeding magnitude 5.0 disrupted rescue operations for days.
The Video: Security Footage of Ground Rupture in Real Time
Footage Description
In early May, civil engineer Htin Aung posted a security-camera clip on Facebook that has since gone viral. The camera, mounted at the entrance of GP Energy Myanmar’s solar farm near Thapyay Wa, records a calm morning with solar panels glinting in diffuse sunlight. Within seconds, gentle tremors emerge—unremarkable at first—knocking the facility’s entrance gate askew and sending dust clouds from unsecured equipment.
At the 14-second mark, the video captures the earth itself fracturing. A jagged crack opens a meter-wide and extends across the roadway, while the ground on one side of the fault slides laterally by an estimated 3.6 meters—a displacement confirmed by post-quake field measurements. Several nearby light poles sway violently before snapping, and panels of fencing whip like sheets in a gale as the land continues to shift for several more seconds. Only when the tremor subsides does motion cease, leaving the facility’s entrance irrevocably split.
Seismologists’ Reactions
“To my knowledge, this is the best video we have of a throughgoing surface rupture of a very large earthquake,” says Rick Aster, a geophysicist at Colorado State University. Aster notes that while ground ruptures are often inferred from mapping and measurements after an event, direct visual documentation—especially with clear scale and duration—is almost unheard of. He points out that capturing such footage can improve our understanding of fault mechanics, rupture propagation speeds and the locality of maximal stress release.
Mechanics of a Supershear Earthquake
Supershear Rupture Explained
Most strike-slip earthquakes rupture at speeds below the shear-wave velocity of the surrounding rock. However, in a supershear event, the rupture front outruns these waves, causing a Mach-cone–like effect that concentrates energy and can intensify ground shaking. The March Myanmar quake’s estimated rupture speed of 4.2 kilometers per second exceeded the local shear-wave velocity (~3.5 km/s), introducing an abrupt, high-frequency loading on structures.
Implications for Fault Dynamics and Hazard Assessment
Such supershear behavior alters stress distribution along the fault, potentially increasing the likelihood of triggered failure on adjacent segments. “Observing a supershear rupture in the field, and on video, helps validate our dynamic rupture models,” says Dr. Sara Liu, a researcher at the University of California, Berkeley. Liu underscores that incorporating supershear parameters into seismic-hazard maps could refine predictions of ground motion intensity for future events in fault-dense regions.
Field Investigations: Mapping Surface Displacement
Post-Event Surveys
Immediately following the quake, engineering geologists scrambled to map the rupture trace. Teams on motorbikes and in four-wheel drives followed the fault line for hundreds of kilometers, marking offsets at roads, canal embankments and building foundations. Maximum lateral displacement peaked at roughly six meters near the village of Kyunhla, tapering northward and southward along the rupture. Vertical deformation—up to 30 centimeters of uplift or subsidence—accompanied the lateral shifts in places with complex fault geometry.
Digital Elevation Models and Remote Sensing
Satellite-based synthetic-aperture radar (SAR) data confirmed the movie’s observed 3.6-meter offset at Thapyay Wa, while drone surveys produced high-resolution digital elevation models. These datasets revealed that surface rupture closely mirrored subsurface fault geometry inferred from aftershock distributions and seismic-wave inversions, affirming that the Sagaing Fault indeed broke end-to-end over the segment.
Human and Infrastructure Toll
Roadways Buckled, Utilities Severed
The violent ground displacement sheared asphalt highways and pulverized concrete bridges, forcing emergency services to reroute and slowing lifesaving aid to remote communities. Critical conduits—water pipelines, communication cables and power lines—were severed where they traversed the rupture zone. Restoring connectivity required patch repairs and emergency bypasses, a process taking days to weeks depending on terrain and aftershock hazards.
Architectural Damage in Mandalay and Beyond
In Mandalay, colonial-era brick structures, Buddhist monasteries and modern high-rises all felt the quake’s wrath. Collapse patterns varied by building type. Unreinforced masonry walls pancaked, while reinforced concrete frames exhibited beam-column joint failures. Soft-story failures occurred at ground-level retail spaces retrofit from older structures. Some new constructions built to international seismic codes fared better, though nonstructural elements—cladding, glazing and interior partitions—suffered heavy damage.
Long-Term Consequences and Reconstruction Challenges
Seismic Retrofitting and Building Codes
Myanmar’s lack of robust seismic-design standards emerged as a primary lesson. Post-quake, the engineering community is advocating for updated building codes that mandate ductile detailing in concrete, bracing for masonry and flexible gas and water connections. Retrofitting historic and vernacular buildings poses cultural and financial challenges, as preservationists and structural engineers seek compromises to safeguard heritage while enhancing resilience.
Community Recovery and Mental Health Impacts
Beyond physical reconstruction, the quake’s trauma has scarred communities. Surveys by humanitarian organizations report elevated rates of post-traumatic stress disorder, anxiety and depression among survivors. Rebuilding efforts must integrate psychosocial support—temporary housing communities, counseling services and memorial activities—to foster collective healing.
Advances in Earthquake Science and Early Warning Prospects
Leveraging Video Data for Research
The Thapyay Wa footage is already informing laboratory experiments and computational models. Researchers simulate surface rupture in large-scale shaking tables, incorporating the observed rupture speeds and displacement magnitudes to test how various ground-motion inputs affect building models. Video-based motion capture techniques are being refined to analyze rupture propagation in natural settings.
Towards Real-Time Surface-Rupture Warning
While early-warning systems can detect P-waves and alert populations seconds before shaking arrives, predicting surface rupture zones in real time remains out of reach. However, dense networks of ground-motion sensors coupled with rapid satellite imaging may one day map rupture onset and direct first responders away from torn ground. Dr. Aster envisions “tiled arrays of cameras along known fault lines feeding into AI systems that flag ruptures as they happen,” providing invaluable situational awareness during major quakes.
Conclusion: A Call to Preparedness and Innovation
The March 2025 Myanmar earthquake and its stunning video documentation of ground rupture serve as stark reminders of Earth’s dynamic power and the fragility of human constructs. For a nation long accustomed to seismic risk, the event underscores the urgency of bolstering building resilience, upgrading infrastructure and integrating mental-health support into disaster response.
At the same time, the unprecedented visual record offers scientists a rare window into supershear rupture dynamics, spurring innovations in experimental seismology, remote sensing and early-warning research. By translating these insights into stronger building codes, more effective emergency planning and advanced monitoring networks, the global community can better anticipate, survive and recover from the catastrophic shocks that lie hidden along the world’s active fault lines.
As Myanmar’s engineers, policymakers and citizens embark on the arduous road to reconstruction, the lessons gleaned from both the ground’s dramatic split and the countless human stories of loss and resilience will shape a safer, more prepared future—one where the ground may crack, but society’s foundations stand firm.
