Katanuma volcanic lake (Miyagi Prefecture, Japan)

Katamuna lake, Japan

Volcano: Katanuma (see Katanuma at the Smithsonian Institution website in a new tab)
Type: Lake
Description: Katanuma is a crater lake with strong acid water (pH:2.0–2.2) influenced by the volcanic fluids. The lake forms an ellipse of 462 m E-W length and 326 m N-S breadth, with a 1380 m of shore line it has neither inflowing nor outflowing streams. In the bottom of the lake there are some high temperature zones where hot springs flow out. These zones are located at the south and northeast basins of the lake’s deepest area. Degassing through the lake surface occurs by bubbles (convective/advective degassing) or by diffusion through the water/air interface (Mazot and Taran, 2009).
