Powerful volcanic eruptions produce ash plumes that can create their own weather systems, providing the conditions for lightning at higher altitudes than normally seen.

A Tongan volcano plume produced the most intense lightning rates ever...

Mauna Loa eruption: Predicting lava flow

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
