Elevated seismicity and deformation at the summit of Mauna Loa volcano, Hawaii

While the largest volcano on Earth -- Mauna Loa is not erupting, rates of deformation and seismicity at the summit remain slightly elevated and above long-term background levels. Other Mauna Loa monitoring data streams show no significant change in deformation rates...

Increased seismicity and ground deformation at Mauna Loa volcano, Hawaii

Activity at Hawaiian Mauna Loa volcano has risen to levels comparable to a higher period of activity between 2014 and 2017, HVO scientists said. The last eruption at the volcano took place in 1984. While there is no cause for alarm, those signs of higher activity...

Alert level increased for Mauna Loa volcano, Hawai'i

The Hawaiian Volcano Observatory (HVO) announced on September 17 they are elevating the Mauna Loa volcano alert level to Advisory and the aviation color code to Yellow due to elevated seismic activity under the volcano. This increase in alert level does not mean that
