HONOLULU, Hawaii (HawaiiNewsNow) - Scientists on the Big Island are considering raising the alert level for Mauna Loa.
Experts say there’s been a slight increase in the number of earthquakes at the volcano over the past month. The largest was a magnitude 3.4 on May 1.
But gasses and temperatures within the summit caldera show no significant changes.
The alert level for Mauna Loa and Kilauea ― whose eruption last year in lower Puna destroyed hundreds of homes ― are currently both at normal.
The next step in the volcano alert system would be “advisory,” followed by “watch” and “warning.”
Mauna Loa is the largest active volcano on Earth. Since 1843, the volcano has erupted 33 times.
It last erupted in 1984.
