Trouble in Paradise: awakening Mauna Loa

Mauna Loa keeps paradise interesting. It has erupted 33 times since 1843, and large eruptions have happened on average once every 8 years. Over that time it has covered its slopes with 4 km3 of new lava. But those were just the most recent stirrings. Its older lava flows cover over half of the island of Hawaii. But after the large eruption in 1950, Mauna Loa became remarkably quiet. There have been only two eruptions since, one of which (1975) lasted less than one day and was the second smallest eruption of the 20th century. There was one significant eruption in 1984, but nothing since. But now the largest volcano on Earth is stirring. Inflation shows that magma is accumulating, just south west of the peak. Earthquakes are a daily occurrence and HVO has raised the alert level. There is trouble brewing in paradise.
