A volcano in the middle of the Pacific Ocean erupts, causing an underwater landslide that is expected to be deadly
The tectonic plates are moving in a different direction, as they have for millions of years, says geophysicist David Tuller, the head of the Carnegie Institution for Science’s Geophysics Group.
“That has the effect of making earthquakes much less likely.”
A large landslide that appears to have come from the ocean could be deadly.
A large landslide on the island of Hawaiʻi on October 4, 2021, left a trail of water and debris that reached nearly 300 miles (500 kilometers) offshore.
Volcanic eruptions on the west coast of the Hawaiian islands are not uncommon, but this one was unusually large.
What are the possible causes?
The landslide was generated by an underground landslide from an underwater eruption in the area known as Krakatoai, Tullers research indicates.
Krakatofire erupted in October 2020, and scientists have not been able to pinpoint the exact location of the landslide.
The Hawaiian Volcano Observatory (OHVO) says that the landslide appears to be triggered by the Krakatahean volcano’s massive flow of magma.
Why are there so many landslides on the Hawaiian Islands?
“There are probably more landslides than any other place in the world,” said Tullery, who was not involved in the study.
“They are like an open sewer.
It could be very destructive.””
It seems that this one, unlike others, could be a very powerful earthquake.
It could be very destructive.”
