The rim of one of the three craters filling the large summit depression of Turrialba volcano is seen in the foreground with the wall of the breached summit depression in the background. This depression is 500-800 m wide in a NW-SE direction and 2200 m long in a NE-SW direction and is of possible slope-failure origin. Historical eruptions during the 18th and 19th centuries have originated from the three small craters within this depression.
