Seismic activity and an anomalous fumarolic chemical composition due to seal effect in the volcanic system of Deception Island (Antarctica)

In this communication, the genesis of great anomalous seismic activity registered during austral summer 2003/2004 on Deception Island (Antarctica) is discussed, and related with changes on the chemical composition of fumarolic gases and vent deposits. Here we present a comparative analysis performed...
