Fresh black lava fills the floor of Santiago crater in December 1976. A new lava lake appeared on the floor of Santiago Crater on October 20, 1965, marking the beginning of Masaya's third 20th-century lava lake cycle. Several lava flows occurred on the crater floor between 1965 and 1972. The spatter cone collapsed in 1972 and lava lake activity was visible until 1979, when the lava lake subsided, producing thick gas emissions.
