#46: How science can protect infrastructure and homes

In this episode, host Andrew Geary speaks with Priyank Jaiswal, Associate Professor at Oklahoma State University. Dr. Jaiswal discusses the recent SEG near-surface event, Forum on Infrastructure, and how geophysics can play a role in this critical area. Andrew and Dr. Jaiswal discuss the potential threats to infrastructure from low-level earthquakes, how citizens and public officials can monitor and address the impact, and how geophysicists can contribute to the safety of infrastructure.

lateral saddle . An adoral inflection of a suture of a nautiloid or ammonoid shell between the ventral and dorsal lobes; in coiled conchs, lateral saddles may be external or internal according to whether they are on the flanks or dorsal areas (TIP, 1964, pt. K, p.57).

Bill to be Signed into Law to Reauthorize the National Earthquake Hazards Reduction Program

By Laura Szymanski, GSA Science Policy Fellow

A bill to reauthorize and amend the National Earthquake Hazards Reduction Program (NEHRP), S. 1768, was sent to the President’s desk on 27 November 2018.  NEHRP was established by the Earthquake Hazards Reduction Act of 1977 to improve the understanding of earthquakes and their effects, develop methods to reduce the impacts of earthquakes, and improve communities’ earthquake resilience.

New Guidelines on Use of Photography at AGU Meetings

AGU is committed to creating a productive and open environment for meetings and all venues that are focused on the exchange of knowledge. Our guidelines are designed to support this commitment while allowing for the exercise of personal preferences. For example, AGU has welcomed the use of social media at our meetings for several years.

AGU Helps Science and Scientists Make a Local Impact

Several students and early career members of AGU have told me that they chose a career path in science for both the excitement of curiosity-driven science and the feeling that science can help them contribute to making the world a better place. Indeed, AGU’s mission includes both promoting discovery in Earth and space science and doing so for the benefit of humanity. Figuring out how to do that second part—benefiting humanity—can be challenging and even frustrating, especially when we are confronting large and urgent problems that need deployment of solutions quickly. Climate change is a good example. Scientific discovery of the Earth climate system has clearly identified an anthropogenic cause for much of the climate change observed during the last several decades or century, and that knowledge is clearly a great benefit, but individuals and communities often struggle to find how they can best contribute to on-the-ground solutions.

No More Time to Waste: Moving Science to Action at Scales that Matter

In the last two decades, a significant fraction of the geoscience and global environmental sciences communities have seen a shift in thinking – from science as its own fundamental goal, to science for understanding change, to science that supports and drives action.
