EPL’s Top Questions in Geophysics and Geodynamics

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.


Behind the Scenes: In the Geophysics Lab with Steven Golden


Steven Golden is an Observational Geophysical Technician at the Carnegie Science Earth and Planets Laboratory. He works with the staff geophysicists Lara Wagner, Diana Roman, and Helene Le Mevel to process and archive seismic, volcanological, and other geophysical data.


What causes the deep Earth’s most mysterious earthquakes?


The cause of Earth’s deepest earthquakes has been a mystery to science for more than a century, but a team of Carnegie scientists may have cracked the case.


When Earthquakes Strike, Some Seismologists Turn to USGS Data

When Diana Roman, a Carnegie Science staff scientist and seismologist, looked at the initial USGS report, she was relieved. Roman explained, “Almost immediately, we were able to see that it was a type of event [strike-slip] that we don’t associate with tsunamis. So that was the first good sign.”


Year-Long Exploration Aims to Add Gravity to the Volcano Monitoring Toolkit

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.
