The last eruption of this stratovolcano occurred in March 1944. A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas.
It is locally known as El Viejo, which translates as the old one.. San Cristobal is a stratovolcano that has a basaltic cone with a flattened top. This cone is built of alternating layers of lava and tephra. These alternating lava layers allowed the volcano to grow large by keeping the tephra layers from eroding.ava from San Cristobal is aa. It is uniformly basaltic with many phenocrysts. These lavas are also very rich in vesicles. Lava flows from San Cristobal are usually between 10 and 13 km in length with a single vent leading to each flow.
