Title: Estimate of Volcanic Production Rate for Galapagos Islands, Ecuador: ABSTRACT

Author(s): Kathleen T. Auer

Article Type: Meeting abstract


The Galapagos Islands, located midway between the East Pacific Rise and the South American continent, constitute one of the most volcanically active regions of the world. Satellite imagery, aerial photographs, and previous land surveys were used to estimate the volume of material produced from the

islands' six active volcanoes over the past 36 years. This Galapagos volcanic production rate estimate is used to calculate the contribution of Galapagos volcanism to global volcanic activity and allows comparison to the production rates of other active volcanic fields. In addition, a detailed account of the location and extent of 15 incompletely documented volcanic events has been established.
