Description
From Yogodzinski and others (2015) [1] : The "Ingenstrem Depression - a fault-bounded rectangular basin, approximately 60 km long by 10-15 km wide and 2000 m deep, which sits along the crest of the Aleutian ridge, between Attu and Buldir islands. Seafloor mapping reveals the presence of many small volcanic cones and associated lava flows, in and around the margins of the Ingenstrem Depression. The largest cones have base diameters of 2-4 km and are 300-600 m in height. Most appear to be undeformed, constructional volcanic features. Spatial analysis of bathymetric data indicates that there are 134 volcanic cones in the Ingenstrem Depression, which constitute a combined volume of 10 cubic kilometers - a volume similar to that of single, small, emergent calc-alkaline volcanoes found throughout the arc ( [2] )."Name Origin
Ingenstrem Depression Volcanic Field is an informal name given to these volcanic vents by Yogodzinski and others, 2015.
