Recently, the Gran Cratere of the Fossa cone has been the site of
volcanic unrest which began around 1985 and ended in 1995 without
culminating in an eruption. Moreover, the most notably sign was an
increase of the fumarolic activity. This episode has triggered
increased public awareness about the volcanic risk at Vulcano island and
intense studies of the volcano. Geological studies have shown that
most eruptions of the Fossa cone have been violently explosive and
produced pyroclastic flows and surges. Future eruptions have to be
expected to be of a similar character.
At nowdays a field of active fumaroles and extensive sulfur deposits
lies in the northern-central portion of this crater. It provides a
thrilling experience for those who dare to walk (or run) right
across the gas plume emitted from the fumaroles. The vivid stench of
sulfur dioxide within the plume is just the most evident indicator
of toxic gases. It is advisable to stay as briefly as possible
within the plume and better wear a gas mask. Prolonged stays in the
plume may lead to undesirable effects, such as the (irreversible)
loss of the sense of smell.::
