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.

June 8 was World Oceans Day, a day to appreciate the huge body of saltwater that covers about 71% of the Earth’s surface.
