    112: International partnership for volcano early warning – A GWB story

    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.

    108: Seismic processing - Begin with the end in mind

    108: Seismic processing - Begin with the end in mind

    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!

    107: The low-cost/high-reward for using multi-component imaging

    107: The low-cost/high-reward for using multi-component imaging

    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.

    Visit https://seg.org/podcast for the complete show notes and links for Xiaogui's free lecture.

    BIOGRAPHY
    Xiaogui Miao, Ph.D. quested after multi-component imaging and processing technologies for more than 20 years. Dr. Xiaogui Miao has the expertise and possessed extensive experience in land 3D3C and Ocean Bottom Sensor (OBC & OBN) 3D4C imaging from North America to Asia Pacific (APAC) region. After graduation from the University of Manitoba, Canada with a Ph.D. in geophysics, Dr. Xiaogui Miao joined Veritas Geophysical Services Ltd. in Calgary, Canada in 1994, then became a geophysical research scientist there. In 2008, after Veritas and CGG merged, she was assigned as research and processing center manager at CGG’s newly -opened Beijing Center, then moved to Singapore in 2015, the APAC Hub of CGG, where she has since been in charge of multi-component and seabed imaging research.

    Dr. Xiaogui has developed a variety of multi-component processing and imaging technologies and published many articles. Her recent research work has involved the development of surface wave and guided wave inversions for shear wave statics correction and shallow Vs and Vp model building, PS wave OBS data velocity analysis from rough seafloors, and incorporating of PP and PS data for wavefield leakage reduction, etc. She also has played a crucial role in providing technical advisories and supervisions to overcome serious challenges in different types of multi-component processing and imaging projects in the APAC region from land to OBC/OBN and from shallow water to deep water. Her areas of study have covered from Cuu Long Basin, Offshore Vietnam, Malaysia Basins, Indonesia’s LNG and gas fields, to Bohai Bay, Offshore South China Sea, and Xinjiang of Northwest China, etc. To demonstrate the values of multi-component technology, she has pushed converted wave imaging into joint PP-PS inversion for reservoir characterization so to enhance the opportunities of hydrocarbon discovery as well.

Aillemaco ,

This is a fantastic delivery from SEG!

It's about time we have something that we can listen to on the go. The material covers a diverse range of topics under the geoscience umbrella and I believe that those of different levels of interest in this field would have the opportunity to seek breadth in learning through these podcasts. I just informed my colleagues about this. Hope they'll find it enjoyable too.

Jorge F. Concheso ,

A must-listen for any geoscientist

I started listening to Seismic Soundoff a couple of weeks ago, and I became inmediately hooked. What a great show! There is a phenomenal variety in the topics presented. It is a treat to listen to household names in the industry, like Kurt Marfurt, Jim Gaiser, Lev Vernik, among many others. And Andrew does a superb job as a host!

Congrats Andrew and Isaac, keep up the good work!

Hojat Lotfipour ,

Good Start

It is a good start! I can listen to the technical talk while I am driving or jugging! Sounds awesome! I just don't know why the order of the files are reverse with regard to time of upload? Is it the format of ITUNE?
