A very large team of researchers from several US institutions came to the conclusion that the volcanic eruption in Kilauea, which took place this past summer, represented an unprecedented volcanic event. In their article published in the journal Science researchers describe the sequence of events and what sets them apart from other volcanic eruptions.
The volcano Kilauea on Hawaii's large island experienced a long, protracted eruption last summer. It made headlines by the spread of lava, which destroyed many homes and changed some of the island's landscapes. And now it's news again, as the breakout's data shows that it broke out in an unprecedented way.
The Kilauea is the world's most active volcano, and therefore scientists have many sensors in and installed in the area, hoping to learn more about its operation and other volcanoes. The volcanic eruption in May delivered huge amounts of data, providing an unprecedented view of the eruption.
The researchers discovered that the caldera did not collapse in the expected manner. First, the air pressure was released by about 500 meters. Second, it happened gradually ̵
The researchers were also surprised This life returned to parts of the sea that were affected by the sudden introduction of molten lava in just 100 days. Oxidizing microbes used the newly deposited lava flows. They also found evidence of hydrothermal activity in the same areas. It is believed that both take longer to find their start after an outbreak.
The volcano is quiet for the time being, but researchers will continue to monitor monitors, especially those set up in the Lower East Rift Zone of Kilauea to look for new activity. You'll also want to keep an eye on Mauna Loa – the other big volcano on Hawaii's big island. It has a history of activity when Kilauea falls silent.
