Geothermal resource development faces a major obstacle: the expensive exploration process. Unsuccessful drilled wells can discourage interest and disrupt economic plans. Understanding the relationship between geologic structures and geothermal fluid flow is critical to successful exploration. Various methods, such as geochemistry, geophysics, structural analysis and modeling, aim to create a reliable model to guide exploration plans. Studying both exhumed and active geothermal systems becomes fundamental to reduce uncertainties and to build pre-drilling models. This approach, using past systems as a …

Most earthquakes on Earth start in the shallow, brittle part of the planet. However, there are several regions where earthquakes happen deep in the mantle. Where are these regions? Why do these earthquakes get so deep? In this week’s blog post, Ayako Tsuchiyama from the Massachusetts Institute of Technology (MIT) takes us on a journey into the mysterious world of deep earthquakes. Growing up in Japan where large earthquakes frequently occur due to the location near plate boundaries, I was …

In January 2023, I visited the Amazon Forest in Suriname. During my visit, I met indigenous people known as the Saramaccers, a Maroon tribe residing in the heart of the Amazon Forest. I found it fascinating that the Saramaccers consider themselves an integral part of nature. Their motto is ‘If you respect nature, nature will be your friend and stand by you’. Nature extends a helping hand to humans more than humans extend to nature. In fact, the natural environment …
