Measurements of gravity can be used to determine how mass is distributed beneath a volcano. At Kīlauea, the Hawaiian Volcano Observatory performs routine microgravity surveys to monitor volcanic activity and to determine changes in gravity.
A magnitude 5.0 earthquake was the strongest of a series of temblors that struck Friday on Hawaii’s Mauna Loa, the largest active volcano on the planet that scientists say is in a “state of heightened unrest.”
