GSH exhibits at the 2026 Shenandoah Valley Gems, Minerals and Jewelry Show. Lisa Bucker shows rock samples, geophones, and explains seismic data.

The item is a galvanometer pencil, Figure 1, a marvel of analog engineering that once served as the literal heartbeat of seismic exploration, translating the silent vibrations of the Earth into visual symphonies of data.

How does a twitching frog leg in an 18th-century Italian laboratory connect to the discovery of massive oil reserves beneath the Earth's surface? The answer lies in the heart of a remarkable historical artifact: the 1929 photographic oscillograph recording camera system used by the Sun Oil Company to pioneer early subsurface seismic exploration. Its core technology is rooted in a bizarre breakthrough in the history of science.

What does a geophysicist do after retirement? People often say that retirement is a time when "the world is your oyster," and there is a great deal of truth in that. For many, it becomes an opportunity to explore interests that a busy career never allowed. For me, that journey unexpectedly led to volunteering with the Geophysical Society of Houston.

GSH SPRING SYMPOSIUM 2026. Geophysical Breakthroughs That Changed Everything. Honoring Tom Smith

Case Study Seminar II builds on the success of the first joint GSH-HGS event delivered in 2024. The joint society committee designed the agenda with one concept in mind: there is no straight path to success, and we learn through trial and error.
