We're excited to see everyone here at SACNAS #NDiSTEM2025—be sure to stop by our booth to say hello!

As Hurricane Melissa makes landfall in Jamaica, we can see its approach over the past few days on seismometers. Strong winds generated by hurricanes create ocean waves and pressure fluctuations that cause stronger up and down movements in the water column, which seismometers record.

We'll be at the @sacnas.bsky.social 2025 NDiSTEM Conference in Columbus, Ohio this week! If you're attending, stop by Booth 1004 to chat with EarthScope staff about research and learning opportunities related to geophysics! #NDiSTEM2025

Looking for web-based tools to easily access and interrogate seismic data? The NSF National Geophysical Facility offers a wide array of online tools for interrogating seismic data holdings and generating files in a number of formats. Online data access tools: https://loom.ly/r8gkW8w

When you see photos of GPS stations, you’re usually looking at the protective radome cover and not the GPS antenna itself. The gray radome helps shield the antenna from rain, snow, and debris buildup and protects it against general wear.

Electrical resistivity tomography (ERT) is a method for learning about the ground below our feet. It can help with finding pumpable groundwater, areas of pollution, hidden caves, and much much more. Watch our full video on ERT: https://loom.ly/LTB_gs8
