Analysis of globally propagating spherical shockwaves from great volcano eruptions using barometric pressure data

Abstract

Summary: Here, we present a protocol for the analysis of barometric pressure data from multiple stations for the globally propagating spherical shockwaves generated by catastrophic explosions. We demonstrate the analytical procedure using the Tonga underwater volcano eruption of January 2022. We also present a protocol to make a data recorder using off-the-shelf electronic components for barometric pressure measurements at ∼1 Hz. The data recorder and the analysis protocol can be used to study similar future catastrophic events.For complete details on the use and execution of this protocol, please refer to Li (2022).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
