A comparison of the 1946 Stearns and MacDonald map (left) and the 1996 BIMP map, digitized in 2005 (right), shows how the understanding of Hawai‘i Island’s geology advanced over half a century. The Geologic Map of the Island of Hawaii is available online at http://pubs.usgs.gov/ds/2005/144/. Paper copies can be ordered from the USGS Publications Warehouse: https://pubs.er.usgs.gov/publication/i2524A (geologic map and explanatory pamphlet) and https://pubs.er.usgs.gov/publication/i2524B (sample map and explanatory pamphlet).

One benefit of passing showers today at Kīlauea's summit was a double rainbow. Halemaʻumaʻu Crater is at the right side of the photo, and the gas plume from the active lava lake can be seen drifting towards the southwest. At the far right edge of the image, visitors take in the view at Jaggar Overlook. Photo taken Tuesday, April 12, 2016 courtesy of USGS/HVO

During the Mauna Loa 1950 eruption, three large, fast-moving lava flows advanced down the west flank of the volcano, each crossing the main highway before reaching the ocean. The Ka‘apuna flow, shown here, traveled from the Southwest Rift Zone vent (7,800 ft elevation) to the coast in just 17 hours, creating a huge steam plume as lava flowed into the sea. The glowing edges and fast-moving channels of the 10- to 25-ft thick ‘a‘ā flow appear white in this June 2, 1950, aerial image. Photo courtesy of Air National Guard, 199th Fighter Squadron.

Volcano Watch: Mauna Loa 1950 eruption – A lot of lava with little warning

Mauna Loa, the largest active volcano on Earth, is not erupting, but is stirring. Seismicity remains elevated above long-term background levels, and ground deformation indicates continued inflation of a magma reservoir beneath the volcano.
