Monitoring Volcanic Craters with Infrasound “Music”
Volcanic craters act as giant horns that emit intense low-frequency sounds. Changes in this infrasound may be used to track rising lava lakes and identify signals of future eruptions.

Role of Continental Arcs in Global Carbon Dioxide Emissions
Continental arcs are a major player in global carbon dioxide emissions, but quantifying that relationship is hard. A new study accepts the challenge on a global scale over 750 million years.
