The Nicaraguan volcano Masaya and its caldera
View through CrossRef
The Masaya Caldera and its included vents offer the volcanologist unusual opportunities for study. The caldera, which measures 11.2 by 6.0 km, is of the Hawaiian type and contains eleven recently active vents. The Masaya‐Nindiri group of vents have been the most active in historic times and descriptive accounts of them go back to 1529. A sympathetic relationship between at least four or five volcanoes in the Nicaraguan chain is indicated by coincidence of eruptions. Cyclic activity in these volcanoes is strongly suggested by records of eruptions during the 19th and 20th centuries and may be substantiated by further data. The Masaya rocks are augite‐olivine basalts of uniform composition. Attempts to control the emission of gases which have devastated a valuable coffee‐producing region have proved futile but have provided new insights into the structure and behavior of the Volcano.
