New findings from the Fagradalsfjall eruption in Iceland could help understand how volcanoes work

A discovery can change the world, but it’s not something that everyone can find. However, scientists and volcanologists have revealed important findings about how people understand volcanoes.

Matthew Jackson, an earth scientist at the University of California, Santa Barbara, and his team have uncovered a process they considered far more dynamic than anyone had assumed in studying volcanoes for centuries, according to an article in science daily.

The majestic view of the Fagradalsfjall volcano on the Reykjanes Peninsula, southwest Iceland.

It was a long time before Jackson and his team witnessed the birth of Fagradalsfjall in Iceland. The results of the geologists study were published in the journal Nature.

according to Earth Observatory From the National Aeronautics and Space Administration (NASA), a new volcanic eruption occurred at Fagradalsfjall in Reykjanes in Iceland on August 3, 2022. It added that Meradalir Valley, the site of the eruption, was about 1 km in length from last year’s eruption at Geldadalir. The volcanic eruption was preceded by weeks of the earthquake.

Reports stated that the eruption of the Vagradalsville volcano did not threaten people’s lives and property. The volcano showed a rapid eruption in which lava did not erupt from the crust.

According to the world of the earth Jackson Who witnessed the Fagradalsfjall, the earthquake swarm was severe, with 50,000 or more earthquakes that shook the earth for weeks and brought Icelanders to the brink. He said the earthquakes were of magnitude four or higher.

On the other hand, he said there could be more than 1,000 factors of change rates for chemical indices and samples from the volcano in Iceland.

Surprisingly, the Fagradalsfjall eruption revealed more compositional diversity than Mount Kilauea in decades. Kilauea is located in the Hawaiian Islands, and is considered active in the volcanic mass.

When the volcano erupted, visitors and scientists were amazed to see a closer look at the scattered lava that slowly flows due to winds blowing the gases away.

in ScienceDailp., the research paper describes the eruption as “depleted magma”. Experts said they hadn’t noticed before in almost real time.

  • By April, evidence revealed that the room was said to have been recharged. It could be through a deeper, fertile type melting with a different composition originating from the upwelling mantle plume regions under Iceland.
  • The new magma showed a lower modified chemical composition, indicating the higher magnesium content of carbon dioxide. Indicates that gases of deeper magma have seeped out.
  • By May, the predominantly flowing magma has been enriched even deeper.

According to the study, geologists led by Somundur Halldorsson of the University of Iceland wanted to find answers to the biggest challenges faced by scientists studying the volcano.

  • How deep is the mantle from which magma originated?
  • What happens in the volcano’s reservoir before or during eruptions, and how is it stored below the surface?
  • However, they are hampered by the unpredictability of the eruption, the inaccessibility and remoteness of the volcano’s active sites.

Jackson shared that they were surprised when he thought he was about to find out how volcanoes work.
