Researchers puzzle about the tsunami
How did the Hunga Tonga-Hunga Ha’apai eruption trigger waves off the coast of California 5,000 miles away? One theory relates to the missing island.
Scientists are baffled as to how tidal waves traveling thousands of kilometers off the west coast of the United States formed when an underwater volcano erupted in the southwestern Pacific. The Hunga Tonga-Hunga Habai eruption on Saturday was one of the strongest in decades, and was still measurable in distant Alaska. The epicenter was reported below the Pacific Ocean floor, however; no tsunami alert was issued. Wave heights of about one meter were reported in California and Alaska.

“The consequences were so severe that we were stirring our brains about it,” says Michael Poland. American Seismic Observatory. Earthquake-induced tsunamis occur more frequently, so they are better explored, the geophysicist explains. To more accurately predict the tidal waves triggered by future volcanic eruptions, it is essential to understand what triggers them.
So far there are many theories. The Troops Explosion des Hunga Tonga-Hunga Ha’apai list Pressure waves That was felt all over the world.

Significant wave heights in Japan
The 15-meter-high tsunami hit the west coast of the main island of Tongatabu and the smaller islands of Nomaku, Mango and Phonoibua. There are said to be no houses left, most of the buildings and apartments have been completely destroyed, a Red Cross employee told the DPA news agency. Along with shelter, drinking water is currently the most pressing problem.
The island’s government has sent ships to the most affected areas to evacuate residents. She talks about an “unprecedented disaster”. So far, three people have died at the scene – two locals and a British woman. There are fears that more deaths will be reported once remote areas become accessible again.
