Tonga and New Zealand have a long history together. Tonga is the only Pacific country with a constitutional monarchy it is known officially as the Kingdom of Tonga. It is home to around 103,000 people who live on 36 of the country’s 170 islands. Materials provided by Daniel Stolte, University of Bath. 29, 2009, quake in Samoa, American Samoa and Tonga was in fact a triple-quake. Tonga is a group of islands in the South Pacific Ocean, located near Fiji and Samoa. The paper " Estimating the eruption-induced water displacement source of the 15 January 2022 Tonga volcanic tsunami from tsunami spectra and numerical modelling" is published in Ocean Engineering (2022). We are under-prepared for volcanic tsunamis." The Tongan government said on Monday, January 24, that more than 80 per cent of the country’s 105,000 inhabitants have been affected by the ashfall and tsunami. A 6.4-magnitude earthquake has struck off the coast of the Pacific island of Tonga, the US Geological Society has said. "This was a gigantic, unique event and one that highlights that internationally we must invest in improving systems to detect volcanic tsunamis as these are currently around 30 years behind the systems we used to monitor for earthquakes. This is the second strong earthquake to hit the Pacific island after the Hunga TongaHunga Ha’apai volcano erupted on January 15, triggering a tsunami alert.

The volcano is located approximately 70 kilometers from the Tongan capital Nuku'alofa-this distance significantly minimized its destructive power."

"The Tongan tsunami tragically killed five people and caused large scale destruction, but its effects could have been even greater had the volcano been located closer to human communities. He notes that the Tonga tsunami should serve as a wake-up call for more preparedness and understanding of the causes and signs of tsunamis cause by volcanic eruptions. Burma saw two deadly earthquakes just a few months apart with the latter (on the Chinese border) claiming the lives of nearly a thousand. Nevertheless, extremely destructive events took place in Burma, Nepal, China and Armenia. Mohammad Heidarzadeh, Secretary-General of the International Tsunami Commission and a senior lecturer in the University of Bath's Department of Architecture & Civil Engineering, authored the research alongside colleagues based in Japan, New Zealand, the U.K. Earthquake activity in 1988 was relatively low, with only 11 major events and none of magnitude 8.0+ occurring.
