1.
extinct volcano
A volcano considered no longer capable of erupting. The traditional classification opposed 死火山 to 活火山 (active) and 休火山 (dormant), though modern Japanese geology has largely abandoned this three-way split.
Compound of 死 (dead) + 火山 (volcano). The label is now considered scientifically unreliable because some "extinct" volcanoes have erupted again.
Related words
- 活火山: active volcano — currently or recently erupting
- 休火山: dormant volcano — not active, but potentially capable of erupting
- 火山: volcano
- 噴火: eruption
Usage
Still common in general speech and older textbooks, but rare in current scientific writing. Japanese volcanology now classifies volcanoes that have erupted in the last 10,000 years as 活火山.
