Beschreibung:The massive volcano covers an area of 1800 sq km and contains about 860 km3 of lava. It has several eruptive centers and overlies an older Miocene basaltic shield volcano. In the ice ages, it was heavily eroded. Silicic lava domes were constructed about 3 million years ago after the main shield volcano had been built. Lesser activity continued into the Quaternary and probably even the Holocene (less than 11,000 years ago).There are over 20 eruptive centers that have been identified in the central portion of Level Mountain and on its flanks.
