The Rincón de la Vieja Volcano rises to 1,848m(6,061 ft.), but the thermal activity is spread out along its flanks, where numerous geysers,
vents, and Fumaroles let off its heat and steam.
The video includes footage and images from when the Halema'uma'u
Crater vent first opened up as a series of Fumaroles(steam vents)
in March 2008, which is when I was volunteering at the volcano observatory.
