Radial fissure vents are found around the volcano, and vents also occur around the caldera rim.[25] There are at least three[26] parasitic vents with basaltic composition on its lower flanks,[27] with three cinder cones found on the western and southern slopes.[25] One of these cinder cones has been described as a subdued 100-metre-wide (330 ft) vent.[24] The Jaron Cliffs are found on the southern slope.[25]
