It may be possible to forecast the next eruption of Hawai’i’s Mauna Loa – the world’s largest active volcano – more than two months in advance thanks to a new understanding of what triggers its eruptions.

“Hawai’i is often seen as this place in volcanology where it’s so well-studied we must know everything about it, but in the 2020s there are still things yet to be discovered,” says Kendra Lynn at the US Geological Survey’s Hawaiian Volcano Observatory.
