After the submarine volcano eruption, which caused smaller tsumami waves to hit the South Sea island of Tonga, a tsunami warning has now also been issued for the west coast of the USA. In addition, there are already floods in Hawaii. The US National Weather Service (NOAA) announced on Saturday that effects could also be felt on parts of the west coast of the country and in Alaska. A tsunami advisory was also issued for Hawaii. So far, however, no damage has been reported there, it said.
What does a “tsunami notice” mean?
A “tsunami advisory” means, according to the Tsunami Warning Center, that “a dangerous wave is underway” and “strong and unusual currents are expected” along the coast and in bays and harbors. The areas from Southern California to Alaska are affected by the warning. These include the California coast, Oregon coast, Washington state coast, British Columbia north coast and Alaska coast. There is also a warning for Hawaii.
Boats are taken out of the water in Hawaii
Boats that were already moved by the tsunami are said to have already been taken out of the water there. “We are relieved that there is no reported damage and only minor flooding on the islands,” the Pacific Tsunami Warning Center said in a previous tweet. According to CBS News, tsunami activity is expected at 6 a.m. (local time) in Alaska, 7:35 a.m. in Fort Bragg, California, and around 8:10 a.m. in the Bay Area, with other areas of the west coast following later. People are told to stay away from the shore and go to high ground.
Alerts for wide Pacific after volcanic eruption
The eruption of one of the undersea volcanoes near the island kingdom of Tonga had previously led to tsunami warnings in large parts of the Pacific. A tsunami warning was issued for all of Tonga on Saturday, according to the local weather agency. Local media said tidal waves inundated properties on the main island of Tongatapu after the Hunga-Tonga-Hunga-Ha’apai volcano erupted. It had rained ash and telephone connections had failed. The extent of the damage was initially unclear late in the evening (local time). According to media reports, Tonga’s King Tupou VI. already brought to safety from the royal palace in the capital Nuku’alofa. According to the Australian Meteorological Agency, a 1.2 meter high wave was observed in the city. The authorities of other Pacific countries also issued tsunami warnings, including Fiji, Samoa and New Zealand. People have been urged to stay away from coastal areas.
Tsunami warning for American Samoa lifted
The US National Weather Service (NOAA) lifted the tsunami warning for American Samoa. The volcanic eruption led to a tsunami. Based on the available data, it can be assumed that the tsunami danger is over, but that there could still be fluctuations in sea level, it said. The volcano erupted on Friday. According to local authorities, only small tsunami waves of up to 30 centimeters were registered the day before. Hunga-Tonga-Hunga-Ha’apai has been active since December. The volcano is about 30 kilometers southeast of Tonga’s Fonuafo’ou Island (also known as Falcon Island).
