Volcano Watch: Magma – What’s hot and what’s not

Scientists at the USGS Hawaiian Volcano Observatory routinely collect lava samples from KÄ«lauea and use the chemistry of these samples to infer the temperature of magma.

Kīlauea Volcano's summit lava lake continued to drop today (May 15, 2015). Measurements of the lake surface late Friday afternoon (May 15) showed that it was 62 m (203 ft) below the top of the newly-created vent rim, a ridge (or levee) of solidified lava about 8 m (26 ft) thick that accumulated on top of the Halemaʻumaʻu Crater floor from multiple overflows of the vent during the past two weeks.

Magma moves towards the Southwest Rift Zone after drop in Halemaumau lava lake

On Wednesday (May 13), the focus of deformation changed to the southern part of Kīlauea’s summit caldera and upper Southwest Rift Zone, where rapid and localized inflationary tilt was recorded.

Volcano Watch: There’s something in the way they move

Volcano Watch: There’s something in the way they move

(Volcano Watch is a weekly article written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.) Over the past four weeks, we have discussed how scientists monitor volcanoes using geophysics, geology, gas geochemistry, and seismology. As we reach the end of January and the second annual Volcano Awareness Month, we conclude our discussion of […]

Research finds magma at shallow depth under Hawaii

Research finds magma at shallow depth under Hawaii

Special to Hawaii 24/7 by Pam Frost Gorder | Ohio State University Ohio State University researchers have found a new way to gauge the depth of the magma chamber that forms the Hawaiian Island volcanic chain, and determined that the magma lies much closer to the surface than previously thought. The finding could help scientists […]
