Kasatochi reported activity

Event Name : Kasatochi 1827

Start:

1827

Observed

"Smoke":

Description: Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Koniuji was smoking in 1827.

Coats (1950) attributes historical eruptions of Koniuji to Kasatochi instead, because Koniuji is "deeply eroded" and "does not appear to have been active in Recent time."
