Extreme Environments Subgroup: External Hazards Monthly FG Meeting

Venue: Virtual
On November 17th, at 3:00PM ET, Dr. Clive Neal from the University of Notre Dame will be giving a talk titled An Overview of Lunar Seismicity!
Apollo showed that the Moon was seismically active with four types of seismicity being recorded. One type - the high-frequency tele seismic events or shallow (?200 km) moonquakes is particularly concerning for human exploration and surface infrastructure. These moonquakes are distinct because of their high frequency components but also because over the lifetime of the Apollo seismic network, at least one per year was recorded with body wave magnitude >5. Coupled with the high seismic Q of the Moon, this means the maximum amplitude of ground motions lasts up to 10 minutes. While none of these occurred within the narrow aperture Apollo seismic network, at least one of these high magnitude events occurred in the region of the South Pole. This talk looks at lunar seismicity and the things to avoid when setting up infrastructure to support a permanent human presence on the Moon.
Our Speaker: Dr. Clive Neal, Professor of Civil and Environmental Engineering and Earth Sciences
Clive R. Neal grew up and was educated in the United Kingdom and became a United States citizen in 2013. He obtained his PhD in geochemistry and petrology in 1986 from the University of Leeds, UK. He moved to the United States later in that year where he spent 4 years as a post-doctoral research fellow at the University of Tennessee – Knoxville. While there, he studied mantle petrology and was introduced to the study of Apollo lunar samples, and has been involved in the study of the Moon since then using samples, as well as remotely sensed data from missions including and since Apollo. He is currently a Professor of Planetary Geology at the University of Notre Dame in Indiana.
Neal continues to publish his research and has over 130 peer reviewed scientific journal articles. He has served on numerous mission and research review panels, including being the Chair of the Lunar Sample Allocation subcommittee 2005-2009, and was a member of the Senior Review panel for NASA’s Planetary Science Division in 2012 and chaired that panel in 2014. Neal was the chair of NASA’s Lunar Exploration Analysis Group from 2006-2010, where he led a community effort to develop the Lunar Exploration Roadmap, and again from 2015-2018, where he formed the LEAG Commercial Advisory Board. In 2019, Neal was invited to give testimony at the sixth meeting of the National Space Council at the Smithsonian’s Udvar-Hazy Center in Chantilly, Virginia. regarding the importance of in situ resource utilization. He is currently a member of the National Academies Committee on Astrobiology and Planetary Science and has helped in the training of future NASA astronauts. In 2021, Neal received the LEAG Service Award, which is given to an individual who has demonstrated extensive service to LEAG and/or the lunar community through excellence in leadership, continuous dedication to mentoring and enriching he early-career community, an extensive track record in the field of science and/or exploration of the Moon. Neal is passionate about NASA and in returning humans to the Moon and beyond in a sustainable, economically beneficial, and permanent way. In 2015, he received the NASA Wargo Award for contributions to the integration of exploration and planetary science throughout his career.
