Mauna Loa erupts in Hawaii as US Geological Service moves from threat to warning

The largest volcano in the world Mauna Loa, broke out in Hawaii over the weekend, but local emergency services were quick to downplay the threat it poses to those in the area. But that does not mean that there is no danger to life and limb United States Geological Survey immediately after the eruption.

The eruption occurred at 11:30 p.m. PST (9:30 a.m. GMT) on Sunday evening, but the lava flow was blocked in the crater of the shield volcano. A warning was nevertheless put into effect for the area ash falls by the outbreak, which can contaminate water supplies, kill vegetation and irritate lungs, but has since been lifted.

However, the US Geological Service is still cautious about the latest eruption, particularly given the number of recent earthquakes in the region, including more than a dozen reported tremors on Sunday. Mauna Loa was on alert raised from advisory to cautionary during the subsequent eruption.

“Based on past events, the early stages of a Mauna Loa eruption can be very dynamic, and the location and advance of lava flows can change rapidly,” he said USGS said, warning that if the eruption moves beyond the volcano’s crater, lava flows “could move rapidly downhill.”

Mauna Loa lava eruptions low in silica and very fluid, and they tend to be non-explosive, which poses the greatest risk to neighboring villages rather than the spread of explosive volcanic rock and molten lava after the initial eruption.

As the population around Mauna Loa has increased over the years, so has the risk lava disaster“which rarely pose a risk to life but can be extremely destructive to infrastructure,” said Dr. Jessica Johnson, a British volcano geophysicist who worked at the Hawaiian Volcano Observatory BBC.

The volcano is one of five that make up the island of Hawaii and is located in the interior Hawaii Volcanoes National Park and rises 13,679 feet above sea level and covers an area of ​​more than 2,000 square miles (5,179 square kilometers). Although there are no recorded eruption deaths, villages were destroyed during volcanic events in 1926 and 1950. The last time Mauna Loa erupted was in 1984.
