Volcano news: Mauna Loa volcano (Big Island, Hawaii)

Mauna Loa volcano (Hawai'i): unrest ends for now, alert back to "normal"

Friday Jun 22, 2018 06:30 AM | BY: T

Volcanic unrest at the volcano has ceased (at least for now), and the volcano observatory lowered the alert level of the volcano back to "normal" (green):

"HVO seismic and deformation monitoring networks have been recording near background levels of seismicity and ground motion at Mauna Loa Volcano for at least the last six months. These observations indicate that the volcano is no longer at an elevated level of activity. Accordingly, HVO is dropping the Mauna Loa alert level to NORMAL and the aviation color code to GREEN."
