A value of 0 is given for non-explosive eruptions, defined as less than 10,000 m 3 (350,000 cu ft) of tephra ejected; and 8 representing a supervolcanic eruption that can eject 1.0 × 10 12 m 3 (240 cubic miles) of tephra and have a cloud column height of over 20 km (66,000 ft). The scale is logarithmic, with each interval on the scale ...
The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Ocean floor.
Several barographs recorded the wave seven times over the course of five days: four times with the wave travelling away from the volcano to its antipodal point, and three times travelling back to the volcano; [29]: 63 the wave rounded the globe three and a half times. Ash was propelled to a height of 80 km (260,000 ft).

An additional complication in determining the highest volcanic summits is defining exactly what constitutes a volcano and how much topographic prominence it must have relative to any nearby non-volcanic peaks in order to qualify. For the purposes of this list, the summits must be an actual eruptive volcanic center, not merely made of volcanic ...
Typical shield volcanoes found in California and Oregon measure 3 to 4 mi (5 to 6 km) in diameter and 1,500 to 2,000 ft (500 to 600 m) in height, [6] while shield volcanoes in the central Mexican Michoacán–Guanajuato volcanic field average 340 m (1,100 ft) in height and 4,100 m (13,500 ft) in width, with an average slope angle of 9.4° and ...
It is the second highest summit in Ecuador (after Chimborazo), reaching a height of 5,897 m (19,347 ft). Cotopaxi is among the highest active volcanoes in the world. Cotopaxi is known to have erupted 87 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano. [2] An ongoing eruption began on 21 ...
