Earthquake sensors offer real-time tracking for reentering space junk

Researchers propose using a global network of seismic sensors to detect sonic booms from space debris as they reenter Earth, enabling reconstruction of their trajectories and potentially pinpointing where fragments might land. In a 2024 Shenzhou 17 module event, 127 California seismic stations recorded the sonic boom, revealing the debris path differed from orbital predictions and suggesting ground impact could occur between Bakersfield and Las Vegas; the approach could speed up locating debris and inform risk assessments, with future work expanding to acoustic sensors over oceans. The study, published in Science, highlights how quake networks could augment current radar/optical tracking in space situational awareness.

"Seismic Sensors Capture Sonic Boom Rattling Montana and Yellowstone"

A loud boom was heard by hundreds of people in southwest Montana, Idaho, and Utah, and was also recorded on seismic sensors in western Montana. The boom coincided with reports of a fireball in the sky, leading experts to believe it was either a meteor or a large piece of space junk entering the atmosphere. Sonic events like this are relatively rare compared to daily earthquakes.

Surge in Attacks Detected by Nuclear Sensors in Ukraine

Seismic sensors originally designed to detect nuclear explosions have been repurposed to monitor explosions in the ongoing conflict between Ukraine and Russia. The sensors have revealed over 1,200 massive explosions in the first nine months of the conflict, providing a clearer picture of the war's impact on areas such as Kyiv, Zhytomyr, and Chernihiv.

Escalating Tensions: Russian Bombings and Nuclear Threats Shake Ukraine

Researchers in Norway and Ukraine have developed a new tool to systematically document Russian attacks in Ukraine by using seismic sensors to track the explosions that shook the earth. By studying data from dozens of earthquake sensors around Kyiv, researchers estimated the position and strength of each explosion, providing objective measurements that can verify what happened during the war. Seismic detections can track blasts at any time, picking up hundreds of attacks that were not previously reported and providing a more comprehensive view of the conflict. This technique could be used in future conflicts to document human rights violations and guide post-war cleanup efforts.

Unveiling Yellowstone's Magma Storage with Seismic Sensors

Scientists have gained new insights into the structure and composition of Yellowstone's magma reservoir using seismic data from hundreds of sensors. The data revealed that the magma is stored in two reservoirs, with the upper reservoir containing more melt than the lower one. The recent study also found that the magma is stored in a sheet-like manner, with horizontally elongated areas of localized magma storage called sills. The improved understanding of Yellowstone's system could help in studying other volcanic systems and improving eruption forecasts. However, many questions about the magmatic system still remain.
