HVO scientists continue to monitor the volcano closely. In an HVO press release on 26 Mar , Frank Trusdell, an HVO geologist who has studied the volcano for nearly two decades, is quoted as saying that "Mauna Loa will erupt again, and there's a good chance that it will be during your lifetime. Views of some data that led to the Aug activity status upgrade:. The oldest remnants of subaerial Mauna Loa are to be found in an interesting rock formation known as the "Ninole Volcanic Series".
It is a series of steep-sided hills, consisting of thin layers of pahoehoe and a'a lava. These hills form the so-called "Ninole Shield" which is thought to be either the remnants of a pre-Mauna Loa volcano, or uplifted blocks of old Mauna Loa from within the Honuapo-kaoiki fault system. Either way, they are some of the oldest exposed rocks on the southern part of the island.

HVO image from , person for scale. It is pictured above rising 13, ft. Since , Mauna Loa has erupted 39 times; its last eruption was in According to USGS estimates, the volcano has erupted an average of once every 6 years over the past The Hawaiian Volcano Observatory celebrated the 30th anniversary of Mauna Loa's last eruption in on March 25, , underscoring that it has been a realtively quite 3 decades at the world's largest active volcano. Views of some data that led to the Aug activity status upgrade: The last decade of seismicity and deformation at Mauna Loa.
Survey Manual. Rising gradually to more than 4 km 13, ft above sea level, Mauna Loa is the largest active volcano on our planet. Its long submarine flanks descend to the sea floor an additional 5 km 16, ft , and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km 26, ft. This makes the volcano's summit about 17 km 55, ft above its base! Mauna Loa is among Earth's most active volcanoes, having erupted 33 times since its first well-documented historical eruption in It has produced large, voluminous flows of basalt that have reached the ocean eight times since It last erupted in , when a lava flow came within 7.
Mauna Loa is certain to erupt again, and with such a propensity to produce large flows, we carefully monitor the volcano for signs of unrest. Skip to main content. Cervelli, who earned his doctorate at Stanford last year, said the university has loaned HVO eight additional GPS stations to monitor the volcano.
Without Stanford's help, this would not be possible. History of destruction. Mauna Loa has erupted 33 times since , spewing out enough lava to cover 40 percent of the Big Island. Increased earthquake activity is another indication that magma is rising to the surface.
