Earthquakes and volcanic eruptions are some of the most powerful events on our planet. They remind us that we aren’t standing on “solid ground.” Instead, there are massive machinations and billions of years of planetary evolution at work beneath our feet. They also offer scientists a rare window into the internal workings of our planet.

In this article, EPL’s geophysicists and geodynamicists highlight five questions that we’re working on to better understand the story of our planet.

A new approach to analyzing seismic data reveals deep vertical zones of low seismic velocity in the plumbing system underlying Alaska’s Cleveland volcano, one of the most-active of the more than 70 Aleutian volcanoes. The findings are published in Scientific Reports by Helen Janiszewski, recently of Carnegie, now at the University of Hawaiʻi at Mānoa, and Carnegie’s Lara Wagner and Diana Roman.

Hélène Le Mével prepares for a year-long study in Chile to study Villarrica volcano, one of the most active volcanoes in the world. The study will include one of the most-extensive monitoring plans to date for the volcano, which is a popular tourist destination. It will also present an opportunity to pioneer the use of gravity as a monitoring tool.
