Predict future tsunami

Shockwave caused by Tonga underwater eruption may help scientists predict future tsunami

Their findings may lead to speedier predictions of these giant waves.

Every minute is crucial when warning people caught in the path of a tsunami. After the 2004 Indian Ocean earthquake, a tsunami in Indonesia reached Sri Lanka in less than two hours. Eight hours later, it arrived on the coast of Kenya. If there had been a way to notify people about the dangers of a tsunami in those faraway areas, it may have been possible to save at least some of the 230,000 victims.
