Mauna Loa volcano began erupting and residents were told to review emergency plans.
It sits immediately north of Kilauea volcano, which is well-known for a 2018 eruption that destroyed 700 homes and sent rivers of lava spreading across farms and into the ocean. Mauna Loa’s volume is estimated to be at least 18,000 square miles , making it the world’s largest volcano when measured from the ocean floor to its summit.The eruption began Sunday night at its summit after a series of large earthquakes. It then spread to vents that formed in a rift zone where the mountain is splitting apart and it’s easier for magma to emerge.
Historically, each Mauna Loa eruption has lasted a few weeks. Hon expects the current eruption to follow this pattern.
