Liverpool, United Kingdom (4E) – Scientists on the National Oceanographic Centre (NOC) had steered in a brand new examine that landslides might set off volcanic eruptions. The examine, revealed in Nature Scientific Reports, is seen as a giant assist to tell “hazard mitigation strategies” of volcanic islands.
These findings after NOC scientists studied Teide, one of many world’s largest volcanoes on the coronary heart of Tenerife.
Previously, the NOC scientists had revealed that Teide’s previous eruptions had been intently linked to submarine landslides at totally different phases after they found that landslides and volcanic deposits have the identical ages and composition.
Studying additional the landslide deposits, the scientists noticed that supplies from volcanic eruptions had been discovered solely within the uppermost layers of every deposit. This might imply that the primary phases of each landslide occurred underwater earlier than every eruption – a powerful indication that the preliminary phases of landslides could have been the set off of the volcanic eruptions.
The NOC scientists additionally appeared into the traits of the skinny volcanic clay layers between eruption and landslide deposits. They estimated that it’s going to take no less than 10 hours for an eruption to happen after the primary submarine landslide.
“This new research shows that after the initial submarine landslide there could be between ten hours to several weeks until the eruption is finally triggered – very different from the near-instantaneous landslide triggering of the 1980 Mt. St. Helens eruption,” examine lead writer Dr. James Hunt stated.
“This information could help inform hazard mitigation strategies for volcanoes similar to Teide, such as Mt. St. Helens or Montserrat,” he stated.
