This study provides substantial first evidence of long-duration Lamb wave imprints in the global ionosphere.

The recent eruption of Tonga’s Hunga Tonga–Hunga Ha‘apai volcano, at 04:14:45 UT on Jan. 15, was recently confirmed by Haystack researchers to have launched far-reaching, massive global disturbances in the Earth’s atmosphere.

Research by Haystack scientists and colleagues (Zhang et al. 2022) was published in the peer-reviewed journal Frontiers in Astronomy and Space Sciences this month.
