How can fossil Geothermal System enhance Present Exploration?

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 …[Read More]

Cross-sectional view showing location of deep earthquakes

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 …[Read More]

Earth Citizens and Natural Hazards: a few words from the perspective of our environment, the inhabited planet, Earth

Hedieh Soltanpour December 4, 2023

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 …[Read More]

Antarctica Uncovered: Exploring the Exposed Surfaces Around the Melting Continent

Evan Quinter December 4, 2023

A photo pf a rocky land with an ice mass in the background. The land has brownish plants.

In 2020, ocean scientists discovered a new island off the Pine Island Glacier ice shelf, naming it after the Norse goddess, Sif. The island is one of many new regions being exposed in the wake of increased ice shelf melting and glacial retreat. While these newly-revealed lands have been discussed in the Arctic and alpine …[Read More]

Offshore Gaza: gas in deep-water sedimentary reservoir rocks as another element in the conflict

Ramon Lopez December 1, 2023

The conflict between the Israeli state and the Palestinian people revolves not only around the control of land but also extends to the ocean, particularly the sedimentary rocks beneath the seafloor (see oil and natural gas fields in the region in Figure 1). This article aims to analyse the geological aspect, specifically sedimentary rocks with …[Read More]

TS Must-Read – Bond et al. (2007) What do you think this is? “Conceptual uncertainty” in geoscience interpretation

The Must-read team December 1, 2023

The Must-Read paper by Bond et al. (2007) is a truly original piece of work, focusing on the conceptual uncertainty that occurs when earth scientists carry out a geological interpretation on data with limited resolution and/or spatial coverage. In this example it is about an interpretation of seismic reflection data (Fig. 1), but it can …[Read More]
