Magnitude 7.7 Earthquake in Myanmar Triggers Evacuations in Bangkok and Scares Residents

A magnitude 7.7 earthquake struck central Myanmar on the afternoon of Friday, March 28, by local time, corresponding to early morning in Brasília, Brazil. The tremor, recorded at a shallow depth of 10 kilometers, had its epicenter approximately 50 kilometers from the city of Monywa in Myanmar, but its effects rippled across borders, reaching Thailand’s capital, Bangkok, where buildings were evacuated. The United States Geological Survey (USGS) tracked the event, which sparked widespread concern in densely populated urban areas. In Bangkok, a sprawling metropolis with over 17 million people in its greater region, alarms blared, and residents fled to the streets seeking safety.

The intensity of the quake caught those in Bangkok’s high-rise buildings off guard. Eyewitnesses reported feeling the shaking for several minutes, prompting hundreds to evacuate offices, shops, and homes in the city center. Footage shared on social media captured scenes of chaos, with crowds gathering in open spaces as structures swayed. Despite the significant magnitude, no immediate reports of severe structural damage or casualties have emerged from Bangkok, though local authorities remain vigilant, assessing potential impacts.

In Myanmar, where the earthquake originated, details are still limited. The epicenter’s proximity to both rural and urban areas raises concerns about the effects on less seismically resilient buildings. So far, no official statements have confirmed casualties or collapses at the epicenter, but emergency teams have been deployed to investigate the situation in the affected regions.

Panic grips Bangkok

The earthquake’s impact in Bangkok was instantaneous. Around 1:30 p.m. local time, security alarms began ringing across various parts of the city, particularly in the bustling commercial and residential districts of the center. Witnesses described the moment as chaotic, with objects tumbling from shelves and furniture shifting inside apartments and offices. In taller buildings, the swaying was even more pronounced, heightening fear among occupants.

Evacuations unfolded swiftly, though not without disorder in some instances. At BTS Skytrain stations, passengers hurriedly exited trains, worried about the structural integrity of the elevated tracks. Videos circulating online show people rushing down station stairs while others congregated in plazas and on sidewalks, awaiting guidance. Police and firefighters were dispatched to manage the safe exodus and prevent overcrowding.

Though the shaking lasted only a few minutes, it was enough to sow widespread panic. Thai authorities stated they are closely monitoring developments. Engineering teams have been sent to inspect public and private buildings, particularly those exceeding 20 stories, which are common in the capital. No collapses have been reported thus far, but the threat of aftershocks keeps residents on edge.

Epicenter in Myanmar: what we know so far

Situated in Myanmar, the earthquake’s epicenter lies in a geologically active zone near the convergence of tectonic plates within the Pacific “Ring of Fire.” The shallow 10-kilometer depth amplified the seismic waves, allowing the tremor to be felt hundreds of kilometers away. Monywa, the nearest city to the epicenter, has a population of about 200,000 and is a key historical and economic hub in central Myanmar.

Unlike Bangkok, where urban infrastructure is more robust, many structures in Myanmar are susceptible to seismic damage. The country has faced similar events before, such as the 2011 magnitude 6.8 earthquake in Shan State, which claimed over 70 lives. As of now, no detailed updates have emerged from Monywa or its surroundings, possibly due to communication challenges in less urbanized areas.

Experts classify the 7.7 magnitude as a “major earthquake,” capable of causing significant destruction near its origin. The absence of immediate reports might suggest a milder impact than anticipated or that data collection is still underway by response teams.

Timeline of seismic events in the region

Seismic activity is not uncommon in the region spanning Myanmar and Thailand. The intense tectonic dynamics stem from the collision of the Indian and Eurasian plates, which gave rise to the Himalayas and other mountain ranges. Here’s a look at key earthquakes in recent years:

• 2011: A magnitude 6.8 earthquake strikes Shan State, Myanmar, with an epicenter 110 kilometers from Chiang Rai, Thailand. Over 70 people died, and 128 homes collapsed in Tarlay.
• 2016: A 6.8 tremor shakes Bagan, Myanmar, damaging 60 historic temples and killing four people.
• 2025: The current 7.7 magnitude earthquake near Monywa affects Myanmar and Thailand, with no confirmed casualties reported yet.

These incidents underscore the region’s susceptibility to earthquakes, particularly in areas with limited disaster preparedness.

Immediate response in Bangkok

Bangkok’s reaction was marked by the speed with which residents vacated buildings. In busy commercial districts like Sukhumvit and Silom, shops shuttered temporarily, and employees were instructed to stay in open areas. Schools and universities halted operations, releasing students while officials assessed facility safety.

The Thai government activated emergency protocols, deploying firefighters and police to guide the public. The Department of Disaster Prevention and Mitigation issued a statement clarifying there’s no tsunami risk but urged citizens to remain cautious of potential aftershocks. While the lack of visible damage offers some relief, uncertainty about further tremors sustains tension across the city.

Online, residents shared their experiences. One person recounted being on the third floor of a building in Nonthaburi, part of Bangkok’s metropolitan area, and struggling to descend the stairs amid the shaking. Another described the shock of watching chandeliers swing in a central shopping mall. Images of mass evacuations spread widely, highlighting the event’s emotional toll.

Expert insights

Sismologists note that the 7.7 magnitude ranks this earthquake among the region’s most powerful in recent years. Its 10-kilometer depth meant energy dissipated quickly across the surface, reaching Bangkok over 700 kilometers away. This also heightens the potential for damage near the epicenter, particularly in Myanmar, where many buildings lack stringent seismic standards.

The epicenter aligns with the Nan Ma Fault, a tectonic feature spanning Myanmar, Laos, and China. Geological studies estimate this fault shifts between 0.6 and 2.4 millimeters annually, and the current quake may have caused a rupture up to 30 kilometers long, based on preliminary satellite data analysis.

While a tsunami threat has been ruled out, experts warn of possible aftershocks in the coming hours or days. These secondary tremors, typically less intense, could worsen damage to already weakened structures, especially in Myanmar’s rural zones.

Potential impacts in Myanmar

As Bangkok grappled with panic and evacuations, Myanmar’s situation remains unclear. The central region, home to the epicenter, includes villages and mid-sized cities like Monywa, which may have sustained significant damage. Limited modern infrastructure and communication hurdles complicate real-time updates, though rescue teams are en route to assess the fallout.

Myanmar has a history of costly earthquakes. In 2011, over 400 buildings collapsed in Shan State, displacing thousands. In 2016, Bagan’s temples, a UNESCO World Heritage site, suffered irreparable harm from a 6.8 quake. Given these precedents, fears linger that the current event could carry serious consequences, particularly in less fortified areas.

Myanmar’s government has mobilized resources, including tents, blankets, and basic supplies, for the affected region. Neighboring countries like China and Thailand have offered humanitarian aid, while international organizations stand by to coordinate relief efforts if needed.

Safety measures in Bangkok

In the Thai capital, authorities ramped up inspections of high-rises and critical infrastructure like bridges and train stations. Engineers are checking for cracks or shifts that could jeopardize safety. Initial reports suggest most buildings withstood the tremor, thanks to construction standards improved after past seismic events.

Residents were advised to avoid re-entering buildings until inspections conclude. In densely populated areas like Pathum Wan, barriers were set up to restrict access to at-risk zones. Public transit, including the BTS Skytrain and MRT subway, underwent checks and resumed partial service, with some lines operating at reduced capacity.

Text alerts urged calm and attentiveness to official updates. Schools and private businesses opted to stay closed for the day, while emergency services remain on standby for any developments.
