Description

The dataset consists of raw signals recorded during the period 15-19 January 2022 by the infrasonic permanent network run by Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo - Sezione di Catania. In this time interval infrasonic sensors detected atmospheric pressure variations produced by the eruption of Hunga Tonga – Hunga Ha'apai volcano, which is about 18000 km far from Mt. Etna. Some of the infrasonic stations installed on Etna recorded both the shock waves coming from the two opposite directions of propagation, and, in the following days, the pressure variations that came after the wave fronts had circumnavigated, several times, the Earth's atmosphere.

Technical info (English)

Infrasound stations are deployed around the summit of Mt. Etna at high and intermediate altitudes. Stations are equipped with GRAS 40AN condensator microphone. The frequency response of the instrument is flat in the range 1- 10000 Hz, and +- 2 dB in the range 0.5 - 20000 Hz.
