The blast that shook the ionosphere

Science Daily  March 17, 2021
An international team of researchers (India, Japan) reported an N-shaped pulse with period ~ 1.3 min propagating southward at ~ 0.8 km/s, as changes in ionospheric total electron content using continuous GNSS stations in Israel and Palestine, ~ 10 min after the August 4, 2020 chemical explosion in Beirut, Lebanon. The peak-to-peak amplitude of the disturbance reached ~ 2% of the background electrons, comparable to recently recorded volcanic explosions in the Japanese Islands. They succeeded in reproducing the observed disturbances assuming acoustic waves propagating upward and their interaction with geomagnetic fields…read more. Open Access TECHNICAL ARTICLE
