The morphology of the summit crater of Tungurahua volcano, seen from the the NNW in 1983, has frequently been modified by powerful explosive eruptions duinng historical time. In 1873, the crater was 500-m wide and 80-m deep. In 1923, near the end of an eruption that began in 1916, the crater assumed its present dimensions of 300 m in width and 200 m in depth. The SE crater rim is 200 m higher than its NW rim.
