May 18, 2019– Mary Greeley News – Scientists on the Big Island are considering raising the alert level for Mauna Loa.
Scientists at the Hawaiian Volcano Observatory say they are keeping a closer eye on Mauna Loa after signs that it is becoming a little more active.
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
Right now, the alert level is at “Normal,” but there is discussion about possibly raising the level to “Advisory.”
An increase in seismicity near the summit of Mauna Loa, and an increased rate of deformation led scientists to think about making the change.
They also emphasize no imminent threat of an eruption, but those who live near the volcano should be aware of the situation.
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.
Mauna Loa is the largest active volcano on Earth. Since 1843, the volcano has erupted 33 times.
It last erupted in 1984.
