Earthquake sensors buried in the quietest spot on Earth: Deep beneath the South Pole, two seismometers will monitor the planet's interior and the movement of Antarctic ice.

The article focuses on the installation of two seismometers deep beneath the South Pole as part of the U.S. Geological Survey's (USGS) $1 million Deep Ice Seismometer project. These sensors, placed 2.5 kilometers into the ice, are designed to monitor seismic activity globally and the movement of Antarctic ice, with the capability to detect earthquakes above magnitude 5. The unique location minimizes environmental noise, allowing for clearer data collection, and the seismometers are expected to enhance understanding of Earth's mantle and core, as well as the dynamics of the Antarctic ice sheet. Once fully frozen, the instruments will be integrated into the Global Seismographic Network, contributing valuable data on seismic events and potential environmental changes.
