2 At the time, Lassen Peak was actively erupting, and there are still plenty of boiling mud pots, evil-smelling steam vents and fumaroles and poison lakes today.

3 El Tatio is the third largest geyser field in the world, with more than 80 geysers and 100-plus fumaroles (spaces where volcanic gas is emitted).

4 The hot fluids model would be consistent with the large quantities of carbon dioxide measured at fumaroles and the shape of the ground’s bulge, which is greater at the epicenter, close to the town of Pozzuoli, Italy, and gradually decreases from there.

5 For scuba divers who prefer to spend their time under the sea, there are plenty of tour operators to take you diving among the reefs and to see bubbling fumaroles.

6 In this part of the world, many volcanoes have active fumaroles (gas vents) that release sulfur and their summits can be covered with sulfur deposits that came from all these hot, acidic volcanic gases rising through the volcano.

7 The yellow crust around steam vents (known as fumaroles) is evidence of sulfur crystallising out of gases and liquids at these volcanoes.

8 Over 500 earthquakes were recorded under the volcano between February 22-23 and with an accompanying increase in fumarole emissions (steam and volcanic gases) from the summit (see above), Ingemmet chose to raise the alert status at Sabancaya to Orange.

9 The terrain is dramatic and varied — volcanic crater lakes, lush forests, fumaroles, waterfalls, black-sand beaches, and azure waves define the breathtaking landscape.
