Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that sound waves from major volcanic eruptions travel completely around the world?

Yes. Major volcanic eruptions, such as the 2022 Hunga Tonga-Hunga Ha'apai event, release tremendous energy that generates atmospheric pressure waves (Lamb waves) capable of traveling entirely around the world multiple times.

Verdict: SUPPORTED · 8 sources for, 0 against · Last checked

The analysis

Numerous empirical studies utilizing satellite, barograph, and ionospheric data confirm that major volcanic eruptions generate acoustic and Lamb waves that circumnavigate the globe.
