  • Although no historic eruptions have been recorded, there are active solfataras on its deep caldera wall.
  • The flows are 'a'a and they flowed towards the west to the caldera wall and then turned north.
  • His party was the first to descend the 800-foot caldera wall to reach the lake's shore.
  • The activity is focused on the Northern Caldera wall, what sort of activity is unknown, but noted that there might be a lava lake there.
  • On April 5, the new 'a'a flow reached the western caldera wall and destroyed about five houses and the main water reservoir.
  • A large fumarolic area, Volcan de Azufre, lies between this ridge and the western caldera wall.
  • The caldera wall was eventually breached, leading to a catastrophic flood as the lake drained.
  • The largest of these is Brown Bear Seamount, to which it is connected by a narrow ridge running roughly perpendicular to its western caldera wall.
  • The southern caldera wall is irregular and a small fumarolic area is found in the western flanks which contains several vents and eject geyser-like water column.
  • The remnant of the primitive volcanic cone forms a precipitous cliff around the island (commonly referred as caldera wall), with a break towards the west.
  • Subsequently, part of the caldera wall has collapsed, possibly due to instabilities caused by hydrothermal activity, and later eruptions have built up a smaller cone inside the now horseshoe-shaped caldera.
  • The area contains high amounts of volcanic glass; a major eruption is still visible in the form of an elongated glassy lava flow extending off the caldera wall, east of the main rift line.
  • As the two streams of ice were compressed between the caldera wall and the new lava domes, the ice moved rapidly downhill, much like the squeezing of toothpaste out of a container.
  • Kintamani is a village on the western edge of the larger caldera wall of Gunung Batur in Bali, Indonesia.
  • The age of collapse is not yet known, but since the caldera formed, volcanic activity has continued along the surrounding ring faults which have produced lava flows and lava domes, increasing the elevation of the caldera wall.
  • As part of an eroded dyke of the volcano, the Rocks are situated just outside the present day caldera wall about 20 km from Mount Warning and three kilometres from Nimbin village.
  • The caldera has a breach in its eastern rim, and in the centre a resurgent dome with an ash cone that forms the highest point of the island: its summit is about 100 m higher than the surrounding caldera wall.
  • Minor eruptions immediately west and east of Vent Mountain produced a small scoria cone (Blocky Cone) and two maar craters (now water-filled) along the base of the southeast caldera wall.
  • The curved shape of the remnants of this first structure indicates that it suffered a massive flank collapse, scattering the nearby forest lowlands with debris and causing a large part of its southern caldera wall to slide off the mountain, forming an embayment lower on its slopes.
  • The Sinnott Memorial Observation Station is built on Victor Rock, an outcropping on the cliff face of Crater Lake's caldera wall, approximately 50 feet below the crest.
