What the Ground Remembers: Long-Term Subsidence and Critical Heads in the Central Valley of California
John Ellis, Principal Hydrogeologist and National Lead on Land Subsidence with INTERA
Land subsidence caused by groundwater extraction has long been a significant challenge in California, with impacts including infrastructure damage, permanent loss of groundwater storage, and many millions of dollars in associated costs. Minimizing and preventing future subsidence requires raising groundwater levels above critical head levels, which often aren’t the same as the historical lows. Effective management of land subsidence under SGMA requires defensible estimates of critical head and a clear understanding of when groundwater-level declines translate into irreversible compaction. This presentation synthesizes empirical observations and modeling results from locations across the Central Valley to examine spatial and temporal trends in subsidence and critical head, informed by DWR's Bulletin 118 - Update 2025. Using a combination of long-term groundwater-level records, subsidence observations, and 1-D MODFLOW CSUB modeling, we evaluate subsidence and critical head trends across various hydrogeologic settings.
From Data to Decisions: Methods to Mitigate Land Subsidence in the Greater Houston Region
Ashley Greuter, Director of Research and Water Conversation for the Harris-Galveston Subsidence District (HGSD)
The Harris-Galveston Subsidence District (HGSD) was created by the Texas Legislature in 1975 is to regulate groundwater withdrawal to prevent further subsidence in Harris and Galveston counties in southeast Texas. The combination of continuous research and annual monitoring that provide key datasets to inform water management planning efforts along with collaboration from regional water providers has successfully stopped subsidence in the coastal region of Harris and Galveston counties.
An Overview of NISAR: NASA’s New Mission for Land Surface Monitoring
Cathleen Jones, Senior Research Scientist at the NASA Jet Propulsion Laboratory
In June 2025, NASA and the India Space Research Organization (ISRO) jointly launched the NASA-ISRO Synthetic Aperture Radar (NISAR) mission to provide near global land imaging that supports studies of geological hazards, hydrology, ecosystems, and the cryosphere. NISAR uses advanced L-band radar imaging to map the Earth's land and ice masses twice every 12 days with ~6-m minimum resolution for U.S. and Indian lands and ~12-m resolution for most other areas. NISAR can be used to measure land surface deformation with the InSAR technique, and the regular cadence of observations enables quantification of subsidence rates, trend analysis to establish normal variability and identify anomalous changes, and evaluation of the underlying processes causing ground movement. In late February 2026, the NISAR mission released a large subset of the imagery acquired since November 2025, and the full data release is expected to begin in summer 2026. This presentation will discuss the mission status and provide overviews of the technology, observation plan, data products, and data access, along with early examples of land subsidence observed by the mission.

AEG Webinar: Get a Job, Create Your Career: A Presentation for Work & Career Aspirations"
AEG Webinar: “Get a Job, Create Your Career: A Presentation for Work & Career Aspirations ”
Join us Tuesday, February 17, 2026, at 1:00-2:30PM EDT
The presentation provides the excitement and challenges of building a career, using my own experiences in the federal government, private industry, and consulting. Three topics (Personal Attributes, Acquiring Your Next Position, & Career Development) are addressed. The talk notes the employer’s perspective, so work applicants or performance-evaluated employees may: appropriately provide materials (resumes and applications for work applicants); respond to interview questions and ask questions of the interviewer; negotiate the benefit package for the position; and prepare for, and respond to, performance evaluations. The presentation also offers suggestions on how one’s career may be tailored [career shaped] over time to an individual’s goals.
Presenter: Greg Hempen, PhD, PE, RG
Cost: Free for AEG members* / $20 for Non-Members

With a background in GIS and geology, Isaac Pope is a volcanologist and remote sensing scientist focused on integrating geospatial and petrologic data to investigate geologic history and hazards. Awarded Goldwater Scholar and All-USA Academic Team while a student at Centralia College, he transferred to Colorado School of Mines where he focused on geologic hazards analysis in landslide, volcanic, and earthquake applications while he finished his B.S. in Geology and Geological Engineering and M.S. in GIS and Geoinformatics. As a Research Physical Scientist intern at U.S. Geological Survey, Isaac worked on risk communication in the Earthquake Hazards Program. He is now a PhD student at Missouri University of Science and Technology.
Abstract details: The Canary Islands are a vibrant landscape teeming with wonder. Staggering views from mountains reaching over 13,000 feet above the tropical Atlantic Ocean beckon millions of visitors every year, yet at the heart of this growing tourist destination is an incredible interplay of volcanology, hazards, and geotechnical engineering. The confrontation of these fields during volcanic events, such as the devastating Tajogaite eruption on the Island of La Palma in 2021, illustrate the dangers when society, science, and politics collide. This presentation will explore the islands’ volcanic history, their hazards, and the science that are working together to build a sustainable future for the beautiful Canary Islands
