Something Strange

In December 2021 an under water volcano erupted in Hunga Tonga-Hunga Ha’apai, that’s in the South Pacific. But then on January 15th there was a huge eruption that was heard around the world. In some places there were tsunami waves up to 148 feet. Several people were killed. I monitored the Infra-sonic sensor and this is what I saw. Look at the noisy trace in the middle. This is the sound ‘heard’ in Palo Alto coming up from the South Pacific. About 12 hours later this trace was repeated coming in the opposite direction. I find it difficult to comprehend a sound wave cycle that is maybe 2 minutes in width as opposed to a 20Hz wave that is 0.05 seconds in width.
