Rapid Characterization of Large Volcanic Eruptions: Measuring the Impulse of the Hunga Tonga Ha’apai Explosion From Teleseismic Waves

Most of the largest volcanic activity in world occurs remote places such as deep oceans or poorly monitored oceanic island arcs. Thus, our capacity monitoring volcanoes is limited to sensing and global geophysical observations. However, rapid estimation eruption parameters needed for scientific understanding eruptive process hazard estimation. We present a method rapidly identify large explosions, based on analysis seismic data. With this methodology, we promptly detect 15 January 2022 Hunga Tonga Ha’apai eruption. then analyze waves generated by explosion estimate its important first-order parameters. further relate with explosivity index (VEI). Our VEI ∼ 6 indicates that how among ever recorded modern instrumentation can provide new insights into physics eruptions.
