Jammertest is an annual open-air PNT/GNSS resilience testing event held at Andøya, Norway, organized by multiple Norwegian government agencies and Testnor. The event provides real-world testing of navigation systems against jamming, spoofing, and meaconing attacks across four distinct test areas, leveraging Andøya's Arctic geography and isolation for high-power signal transmission without disrupting civil infrastructure.
Researcher D. Sarah Stamps' team at Virginia Tech detected magma intrusion beneath Tanzania's Ol Doinyo Lengai volcano in 2024, identifying about a million cubic meters of magma entering an existing reservoir roughly 1.8 miles underground. While modest and not immediately concerning, the finding demonstrates an effective early-stage alert system for predicting explosive volcanic eruptions, which occur at this volcano roughly every 10–15 years.
