Nature : Thanks to GPS units mounted on ocean buoys, it’s possible to measure the timing and extent of tsunamis as they propagate in the open sea. Using those data, a team from Paris Diderot University has looked for the impact of tsunamis on Earth’s ionosphere. Remarkably, the atmospheric wave triggered by a 10-cm-high tsunami contains enough energy and travels far enough upward to perturb the ionosphere’s electron density. The team’s results appear in Geophysical Research Letters .
