(BIVN) – As Volcano Awareness Month wraps up, USGS Hawaiian Volcano Observatory scientists held their third and final Mauna Loa talks story event at the Konawaena Elementary School Cafeteria on Saturday.
We caught up with USGS HVO Scientist-In-Charge Tina Neal during the first talk story held in Hilo a few weeks back. She provided an update on Mauna Loa.
According to the January 25 activity summary posted by USGS:
Mauna Loa Volcano is not erupting. Rates of deformation and seismicity remain above long-term background levels, but rates in the past few months have decreased compared to rates of the past year. Similar decreases have occurred in the past during the ongoing period of unrest; it is uncertain if these lower rates will persist or pick up again in the near future.
Observations: Small-magnitude earthquakes continue to occur beneath the volcano, primarily beneath the summit caldera and upper Southwest Rift Zone at depths less than 5 km (3 miles). Additional deeper seismicity at depths less than 13 km (8 miles) was scattered beneath the southeast flank of the volcano.
Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) measurements continue to show slow deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone.
No significant changes in volcanic gas emissions were measured.
