| Summary: | The births (ages) of most of the active volcanoes, calderas, and large craters produced by caldera-resembling eruptions (subcaldera craters) were dated as a result of geological, geomorphological, tephrochronological, and isotopic studies. The dated active volcanoes were found to be fairly young formations, the age of the oldest being 40-50 thousand years. Most of the presently highly active volcanoes had been born at the very end of the late Pleistocene or during the Holocene. Carbon-14 ages were determined for the majority of the Holocene volcanoes. The periods of time when Holocene volcanoes had been synchronously active were 7500-7800 and 1300-1800 years ago. -from Journal summary |
