In this special episode, Seismic Soundoff features SEG’s humanitarian program, Geoscientists Without Borders (GWB). We highlight Silvio De Angelis’s project to create an international partnership to develop volcano monitoring capacities in Guatemala.

In Guatemala, volcanic hazard is high with over 1.3 million people living within six miles of an erupting volcano, and over 7 million people living within 19 miles. Silvio's goal was to help build an effective early warning and volcano monitoring framework in Guatemala and improve the risk mitigation policies in the region.

This episode will inspire listeners to the usefulness of applied geophysics and the unique funding opportunities through GWB.

BIOGRAPHY

Silvio De Angelis is a Senior Lecturer in Geophysics at the University of Liverpool. De Angelis is a geophysicist with a background in monitoring, interpretation, and modeling volcanic unrest and earthquakes. In the past, he was employed in research and management positions by earthquake and volcano observatories worldwide and played an active role in government scientific advisory committees and risk assessment panels.

De Angelis contributed to the implementation of the first real-time monitoring system based on seismic, infrasound, and thermal infrared technology originally deployed at the Montserrat Volcano Observatory, and later at other volcano observatories worldwide. During his tenure with the Alaska Volcano Observatory, De Angelis developed a new system for the detection and location of remote volcanic explosions, still in use by the US Geological Survey. He has authored over 50 research papers in the fields of earthquake and volcanic seismology, acoustic infrasound, and volcanology. De Angelis brings over a decade of research and field experience at active lava dome volcanoes, more recently at the Santiaguito lava-dome complex. He will contribute his expertise in the analyses and interpretation of seismic data at lava dome volcanoes and multi-parameter monitoring of volcanic systems.

ABOUT GEOSCIENTISTS WITHOUT BORDERS

Geoscientists Without Borders serves as a catalyst bringing capable scientists together with communities to solve their problems. The program provides funding for these projects and assists geoscientists and their teams in collaborating with multidisciplinary and community-based partners. Data is collected, processed, and interpreted to provide resources that result in a sustainable humanitarian benefit to the community.

Geoscientists have the tools necessary to effect positive change in communities coping with environmental hardships and natural hazards. Many places around the globe facing severe water shortages, earthquakes, tsunamis, and other hazards have benefited from the humanitarian efforts of geoscientists who have offered their specialized knowledge and technical skills to those in need.

In this episode, host Andrew Geary speaks with Stephen J. Hill on his new book, Illustrated Seismic Processing, Volume 2: Preimaging.

Along with Steve's co-author Andreas Rüger, this second volume of Illustrated Seismic Processing provides a foundation for understanding the vigorous, relevant, and fascinating field of seismic processing, addressing that portion that precedes migration. Written for the non-expert, this second volume of the two-volume introductory text reveals the limitations and potential pitfalls of seismic data, explains seismic processing operations as a series of solutions to problems, and demonstrates the dependence of a final interpretable seismic volume on its many seismic processing decisions.

In this engaging interview, Steve shares why they decided to present the seismic processing topics in reverse order, tips for seismic interpreters and acquisition specialists that work alongside seismic processing geophysicists, and why seismic processing is both an art and a science. And also discover Steve's journey from an astrophysicist to writing two books on seismic processing!

Dr. Xiaogui Miao highlights her SEG Honorary Lecture 2021 talk, "From multi-component imaging to ocean bottom seismic technology - challenges or opportunities?". In this intriguing conversation, Xiaogui makes a convincing argument that utilizing multi-component imaging is a low-cost and low-effort option for companies to better discover oil and gas. She also discusses how utilizing multi-component technology is like moving from black and white images to color and how recent advancements in converted-wave imaging have addressed long-standing challenges. This episode will challenge the status quo and help the geophysicist make a persuasive case to management to use multi-component imaging.

In this episode, host Andrew Geary speaks with Kerry Key and Chloe Gustafson on their massive freshwater discovery off the East Coast of the United States.

According to the United Nations, 60% of the world's population lives in places with high water stress, meaning that more water is being withdrawn than is currently available.

In this crucial conversation, Kerry and Chloe discuss how they used existing geophysical techniques in a new way to discover freshwater off the United States' Atlantic Coast, the equivalent amount that would fill 1.1 billion Olympic-sized swimming pools.

Kerry and Chloe also share how scientists in other parts of the world could utilize this discovery to find their own sources of freshwater and what the future could look like if electromagnetic methods get widely adopted for seeking freshwater. This is a fun and exciting conversation on how geophysics can help the world. You'll want to share this one with your family and friends!
