Web50 we mainly find seismic events with a transition from high to low frequencies and without clear S-phases. This type of event has been described as hybrid event, combining the features of a volcano tectonic event in the signal onset and of a long-period event with respect to the coda (e.g. McNutt, 2000; Wassermann, 2012). Web14 aug. 2024 · The main types of the seismic signals associated with volcanic activity can be divided into three broad groups depending on their relationship with eruption process: the signals generating during the magma migration within the Earth’s crust, the signals generating within the volcanic conduits, and the signals generating during the … WebVolcanoes generate a variety of pre-eruptive low-frequency seismic signals. Hybrid earthquakes comprise a class of these signals having high-frequency onsets followed by low-frequency ringing.
