Mount Tencho

Tenchozan

화구열 · Japan · 1046m

The Tenchozan volcano is in the center of this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 6 km across). There are two crater chains along the summit area, the 1.8-km-long northern chain consisting of ten craters, and the 700-m-long southern chain consisting of four craters. The individual crater diameters are up to 250 m (northern chain) and 100 m (southern chain), and reach up to 70 and 30 m deep, respectively.

지질학적 요약

Phreatic eruptions at Tenchozan occurred approximately 1,900 years ago. Towards the end of those eruptions there was a phreatomagmatic or small magmatic eruption. The chain of explosion craters, stretching from the NE to the SW, are considered to be a result of this series of eruptions (Goto et al., 2005; Goto, 2011).
