Total solar eclipse led to seismic quiet for cities within its path

As the Moon swallowed the Sun during the April 8, 2024, total solar eclipse, something remarkable happened on the ground—cities went eerily quiet. Scientists analyzing seismic data found that human-generated vibrations, usually caused by traffic, construction, and daily activity, dropped sharply during totality. The effect was so pronounced that it created a clear “seismic hush” across urban areas directly in the eclipse’s path, before quickly rebounding afterward.
