Water from a rooftop pool was filmed crashing 600 feet down a Manila skyscraper on Monday after a powerful earthquake struck the Philippines, killing at least 11 people.
The dramatic footage saw water from an 82-foot-long lap pool, as well as a children's pool, pour down the side of the Anchor Skysuites in the 6.1-magnitude earthquake.
Shared online by The Manila Bulletin and credited to Michael Rivo, the video shocked people online, with many turning to social media to share it.
The Philippines Institute of Volcanology and Seismology reported that the magnitude 6.1 tremor hit the main Philippines island of Luzon at 17:11 local time on Monday, leaving 11 people dead and 30 still feared trapped in the rubble. An airport was also seriously damaged and at least two buildings destroyed.
Less than 24 hours later on Tuesday, a second powerful earthquake measuring 6.4 on the Richter scale struck the Southeast Asia country further south, in the central Visayas region. It is not clear if there are any casualties. The BBC reports that the worst hit areas include Tacloban City, Leyte, and Catbalogan City in Samar.
After the initial earthquake, authorities claimed dozens of people could still be trapped underneath a collapsed building in the province of Pampanga, north-west of the capital Manila.
Governor Lilia Pineda told Reuters news agency that 20 people had been injured there, saying: "They can be heard crying in pain. It won't be easy to rescue them."
Pineda also spoke to ABS-CBN television, and claimed that three bodies had been pulled out of a shop, while a woman and her grandchild were found dead in the town of Lubao.
People caught in the quakes have taken to social media to post photos of the damage caused, including cracked walls and swinging light fixtures.
The Philippines is part of the 'Ring of Fire,' a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
The zone of major seismic activity has one of the world's most active fault lines, and is associated with a nearly continuous series of oceanic trenches, volcanic arcs, volcanic belts and plate movements.
