Our Principal Invesigator, Jadranka \u0160epi\u0107, participated in two papers related to Hunga Tonga-Hunga Ha’apai volcano eruption. <\/p>\n


<\/p>\n

The first paper is dedicated to the atmospheric Lamb waves generated by the eruption. <\/p>\n

The characteristics of acoustic-gravity waves (waveforms, time durations, amplitudes, azimuths and horizontal phase speeds) from the eruption of the Hunga-Tonga-Hunga-Hapai volcano detected at different infrasound stations of the Infrasound Monitoring System and at a network of low-frequency microbarographs in the Moscow region are studied. Using the correlation analysis of the signals at different locations, six arrivals of signals from the volcano, which made up to two revolutions around the Earth, were detected. The Lamb mode of acoustic gravity waves from the volcano eruption is identified and the effect of this mode on generation of tsunami waves and variation of aerosol concentration is studied. The energy released from an underwater volcano into the atmosphere is estimated from the parameters of the Lamb wave and compared with the energy released from the most powerful nuclear bomb of 58 Mt TNT.<\/span>

The second paper is dedicated to tsunamis which formed after the eruption. Two types of tsunamis formed, the first one generated by the initial sea level displacement, and the second one by the atmospheric Lamb waves. <\/span><\/p>\n
