Above Top: Number of earthquakes per day during the past month (blue bars). The red line is the cumulative moment (energy) release. Bottom: Depth of earthquakes during the past week in the area shown on the map above. On both figures, circle-size represents magnitude, and color indicates depth. An interactive earthquake plot can be found on the HVO Earthquakes page.

Deformation Data

Electronic Tilt at Mauna Loa Summit - Past Month

Electronic Tilt at Mauna Loa Summit - Past Month

Above: Tilt data from a site near the northwest rim of Mauna Loa's summit caldera. The tiltmeter responds to daily and seasonal temperature fluctuations as well as possible changes in Mauna Loa's magma storage system.
