Eruptions
The last eruption occurred around the start of the 18th century (c. 1700 ±30 years). There are no historical records of this, but tephrochronology indicates phreatic explosions with mudflows from crater 3. Two centuries before this eruption (c. 1550 ±75 years), radiocarbon dating indicates a similar eruption from crater 2. Around the same time (c. 1500 ±150 years), radiocarbon dating indicates another eruption, but from crater 1. This eruption included debris avalanches instead of mudflows. The oldest eruption that has been dated is an explosive eruption from the east side of the summit around 100 BCE ± 100 years according to radiocarbon dating. All these events were central vent eruptions with a volcanic explosivity index (VEI) of 2.[2]
Climbing Route
A single trail climbs the eastern side of the mountain. It gets progressively steeper as you climb. The trail starts in a forest about one 1 kilometre (0.6 mi) from Poropinai. The treeline is at about 800 metres (2,600 ft). From there the terrain is rocky and alpine. The climb takes 3-3.5 hours.[4][5]
1972 Winter Olympics
At the 1972 Winter Olympics, Mount Eniwa was the site of the men's and women's downhill ski races.[6] The course started at the summit and finished on the southwest slope.[7] The technical events of giant slalom and slalom were held at Teine.
