A catastrophic 7.7 magnitude earthquake struck Thailand on March 28, 2025, sending shockwaves through Bangkok’s skyline. Among the most dramatic visuals of the disaster were the city’s famous rooftop infinity pools overflowing, creating waterfall-like cascades from heights of up to 60 stories. Viral videos captured the moment water poured down high-rise buildings, leaving guests scrambling for safety.

How the Tremors Turned Infinity Pools into Waterfalls

As the earthquake shook Bangkok, the movement of seismic waves caused rooftop pools to act like massive liquid pendulums. The water, unable to remain contained, surged over the edges, transforming serene infinity pools into uncontrolled torrents.

“I was in the Sky Bar when everything started to shake. The pool water began rolling like an ocean wave before it simply… went over the edge,” said Emma Sullivan, a tourist at the Lebua State Tower. “People were screaming, trying to grab their belongings before rushing toward stairwells.”

Luxury Hotels Most Affected

Several of Bangkok’s premier hotels saw their rooftop pools emptied within minutes due to the tremors:

• Banyan Tree Bangkok (61st floor infinity pool) – Witnessed dramatic water overflow, captured in viral footage.

• Waldorf Astoria (16th-floor pool deck) – Experienced rapid water loss and structural damage.

• Bangkok Marriott Marquis (9th-floor pool) – Suffered complete pool drainage within moments.

Eyewitness James Chen, who filmed the incident at Banyan Tree, described the chaos: “The water was literally shooting off the edge like a waterfall. I’ve never seen anything like it.”

Safety Concerns and Structural Damage

The unexpected flooding created several dangerous situations:

• Slip hazards – Waterlogged rooftop floors increased the risk of falls.

• Crowd panic – Guests rushed towards exits, leading to near-stampedes.

• Electrical dangers – Water seeped into lighting and electrical systems.

• Structural stress – Some buildings suffered internal water damage, with potential long-term consequences.

Preliminary engineering assessments reveal that five major hotels experienced electrical failures, and at least two properties may have sustained structural weakening.

“Water intrusion at these heights can cause progressive damage that isn’t immediately visible,” warned Dr. Suchinda Pattanapong of the Thailand Building Safety Institute. “Saltwater from pools is particularly harmful to concrete reinforcement and electrical systems.”

Tourist Safety Guidelines for Future Earthquakes

In the wake of this disaster, safety experts have issued urgent advice for travelers staying in high-rise hotels:

• Evacuate pool areas immediately at the first sign of tremors.

• Use stairs, not elevators, to exit buildings.

• Stay away from windows and fragile glass structures.

• Keep emergency kits with essentials like passports, medication, and water.

Tourism and Business Impact

The earthquake struck as Bangkok was hosting its annual Motor Show, showcasing Chinese EV brands, creating an unusual contrast between disaster-stricken tourism and ongoing commercial activities. As Thailand begins recovery efforts, the incident serves as a stark reminder of the unpredictability of natural disasters—even in the most luxurious settings.

With cleanup efforts underway, the haunting imagery of Bangkok’s waterfall-like infinity pools will remain a lasting symbol of the earthquake’s force and the urgent need for improved seismic safety in high-rise hospitality.
