Abstract

Obenberger says the technique could be used to monitor small human-caused explosions or even remote volcanic eruptions in the Pacific that are otherwise hard to detect. In 2022, the Hunga Tonga-Hunga Ha'apai volcanic eruption in the South Pacific Ocean produced ripples in the ionosphere that were detected thousands of kilometers away. The team's radar detectors were designed to measure the waves bouncing off the ionosphere's E layer, a region 100 kilometers up. [Extracted from the article]
