Mauna Loa volcano (Big Island, Hawai'i) activity update

Friday Oct 30, 2015 06:45 AM | DOOR: T

Seismic unrest continues at the volcano, but at lower levels than during mid-late summer, HVO reports:
"Earthquakes occurred beneath Mauna Loa's upper Southwest Rift Zone at depths less than 13 km (8 miles). Deformation data are still consistent with inflation of magma reservoirs beneath Mauna Loa's summit and upper Southwest Rift Zone."

The alert level of the world's largest volcano was raised a notch to "ADVISORY", and the Aviation Color code to "YELLOW" becuase shallow earthquakes have recently appeared in increasing numbers under the volcano.

Very weak unrest in the form of inflation and seismic activity continues at the largest active volcano of our earth, which has not erupted since 1984. However, this activity is not strong enough to justify a raise of the alert level from green "normal" to yellow "unrest". There is currently no sign that Mauna Loa will erupt any time soon. ...

The latest update of the USGS mentions that minor inflation of a shallow magma reservoir beneath Mauna Loa may be occurring. Seismicity rates were slightly elevated. However, the level of observed seismicity is far from alarming and the alert level remains at green. No eruption is expected in the near future. ... [meer...]
