Man Faced Unexpected Tsunami Waves While Playing At Beach | Tsunami In Hawaii After Tonga Eruption

A large eruption of Hunga Tonga, a volcanic island of Tonga in the Pacific Ocean, occurred on 15 January 2022. The eruption caused tsunamis in Tonga, Fiji and American Samoa; tsunami warnings were issued in Fiji, Samoa, Vanuatu, New Zealand, Australia, Japan, the United States, Canada, Mexico, Chile and Ecuador. Damaging tsunami waves were reported in New Zealand, the United States, Chile and Peru. Two people drowned in Peru when a 2-meter wave struck the coast, and two fishermen in California suffered minor injuries.

Background
After being relatively inactive since 2014,[1] the Hunga Tonga volcano erupted on 20 December 2021, sending particulates into the stratosphere, and a large plume of ash was visible from Nukuʻalofa, the capital city of Tonga, about 70 kilometres (43 mi) from the volcano.[2] The Volcanic Ash Advisory Center (VAAC) in Wellington, New Zealand, issued an advisory notice to airlines.[3] Explosions were heard up to 170 kilometres (110 mi) away.[4] This initial eruption ended at 02:00 on 21 December.[2] Volcanic activity continued, and on 25 December, the island had increased in size on satellite imagery.[5] As activity on the island decreased, it was declared dormant on 11 January 2022.[6]

A large eruption began on 14 January sending clouds of ash 20 kilometres (12 mi) into the atmosphere.[7] The government of Tonga issued a tsunami warning to residents.[8] Tongan geologists near the volcano observed explosions and a 5-kilometre (3.1 mi) wide ash column.[9]

The following day, a significantly larger eruption occurred at approximately 17:00 (04:00 UTC). The VAAC again issued an advisory notice to airlines.[10] Ash from the eruption made landfall on the main island of Tongatapu, blotting out the sun. Loud explosions were heard 40 miles (65 km) away in Nukuʻalofa, and small stones and ash rained down from the sky.[11] Many residents in Tonga were stuck in traffic while attempting to flee to higher ground.[12] The explosion was heard as far away as Samoa, roughly 520 miles (840 km) away.[13][14] Residents in Fiji described the sounds of thunder. Booms were heard in the North Island of New Zealand and as far away as the east coast of Australia. From space, a very wide eruption column and shockwaves were captured propagating across the Pacific by satellites.[15] The pressure wave was measured by weather stations throughout New Zealand at a maximum amplitude of about 7 hPa.[16] The pressure wave was also recorded by weather stations in Australia.[17][18][19] The United States Geological Survey registered the eruption at a surface-wave magnitude of 5.8.[20] A pressure fluctuation of 2.5 hPa was measured in Switzerland.[21]

Preliminary observations showed that the eruption column ejected a large amount of volcanic material into the stratosphere. The eruption has potential to cause a temporary climate effect.[22] A scientist from the University of Auckland described it as a one-in-1000-year event.
