"This is the most powerful volcanic event ever recorded on the most volcanic world in our solar system — so that's really ...

On Dec. 27, 2024, NASA's Juno spacecraft swooped by the volcanic world Io. It witnessed a giant eruption.

A stunning composite image, made up of three years' worth of satellite photos, shows the ancient lava of Libya's Haruj volcanic field interspersed with patches of golden sand.

The resulting tidal forces heated up its interior and thus powered the violent volcanism. Only Jupiter's moon Io, by far the most volcanically active body in the solar system, offers comparable ...

According to the volcanism hypothesis, this global-scale volcanic activity spewed so much gas, ash, and dust into the atmosphere that it kept sunlight from reaching Earth's surface. Temperature ...

Most volcanism on Earth occurs beneath the oceans, but submarine volcanoes are difficult to study. Advances in seafloor monitoring have opened up an unprecedented view of eruptions on the seabed.

My research and teaching concern how magmas and volcanoes are formed, how they evolve and reveal the chemistry of Earth's interior; the role of volcanism in the chemical evolution of Earth and other ...
