Episode 199: How geophysics keeps people safe

Steve Roche discusses his current Geoscientists without Borders project addressing volcano preparedness in Guatemala.

Steve’s GWB project addresses the geohazard resiliency and safety of the communities in Guatemala. His project implements community-based educational workshops about earthquake and volcanic hazards. Steve’s project also works to increase Guatemala’s seismic and volcanic monitoring capacity while reducing disaster response time.

In this inspiring conversation with host Andrew Geary, Steve provides his on-the-ground perspective of the project. He offers what has been accomplished and his vision for the project’s future. This podcast takes joy in highlighting the humanitarian work of geophysicists worldwide. And this conversation is no exception in sharing how geophysics can impact communities through using the tools and knowledge that geophysicists have to give. And Steve is the perfect guest to showcase all that can be accomplished.
