he 15 January 2022 eruption of the Hunga volcano provides a unique
opportunity to study the reaction of the ionosphere to large explosive
events. In particular, this event allows us to study the global
propagation propagation of travelling ionospheric disturbances using
various instruments. We focus on the detection of the ionospheric
disturbances caused by this eruption over Europe, where dense networks
of both ionosondes and GNSS receivers are available. Despite the large
distance from the eruption site, clear effects were detected in this
region. We combine a variety of data, including atmospheric pressure
measurements, ionosonde soundings, TEC data and in situ measurements in
order to track the disturbances across the region. In this way, we are
able to detect the disturbances propagating in both directions along the
great circles from the eruption site to Europe.
