Thanks to its geothermally active location, the town of Kusatsu, Gunma Prefecture (in the background of this image), is one of Japan’s most popular onsen (hot springs) destinations. The acidic and vibrant turquoise Yugama crater lake, however, is definitely not suitable for swimming. Credit: Tomoya Obase

Monitoring ‘frothy’ magma gases could help evade disaster

Viti Crater (formed in the 1724 event), where the Iceland Deep Drilling Project accidentally drilled into magma in 2009. They were drilling there originally to explore the potential for geothermal energy. Credit: Shane Rooyakkers.

Magma ocean may be responsible for the moon’s early magnetic field

Scientists have now made the best computational modeling yet of mantle plumes, hypothesized, mushroom-shaped upwellings of hot rock from the deep Earth. They plumes are hypothesized to form within the thermal boundary layer at the base of the mantle and are thought to carry heat from Earth's core that generates a volcano's magma.
