A satellite image of Tonga’s underwater volcano eruption on 15 January 2022, taken about 100 minutes after it. This can lead to tsunamis – a series of ocean waves caused by the displacement of water.Ī 1.2-metre (4 foot) wave swept ashore in the Tongan capital, with locals reporting fleeing to higher ground, leaving behind flooded houses, some with structural damage, as rubble and ash fell from the sky. According to the Global Foundation for Ocean Exploration group, about “three-quarters of all volcanic activity on Earth actually occurs underwater”.ĭuring an eruption, hot magma forces the oceanic crust open. There are about one million undersea volcanoes – and most are extinct. Tonga is home to several volcanoes, all along the Ring of Fire. Many are located along a 40,000km (25,000-mile) arc along the Pacific known as the “Ring of Fire”, which is also where about 90 percent of all earthquakes occur. Several 'moderate' explosions were registered at Popocatpetl, one of Mexico's most active volcanoes, according to the country's National Center for Disaster Prevention. Bacolcol said there was a possibility the high-risk zone could be expanded if. There are some 1,350 potentially active volcanoes around the world, according to the US Geological Survey. At least 12,800 people living within a 6km (3.7 mile) radius of the Mayon volcano have been evacuated since last week. Robin George Andrews, a science journalist, volcanologist and author of Super Volcanoes, told Al Jazeera from London that “it was the most energetic explosions in the entire 21st century”. Early data suggests it was the biggest eruption since Mount Pinatubo in the Philippines more than 30 years ago. Geological Survey defines a volcano as a vent in Earths surface, either on land or on the seafloor, from which molten rock called magma, as well as ash and gases, can erupt or ooze.
