Volcanology of The Youngest Toba Tuff, Sumatera
The Toba depression in northern Sumatera is a complex structure, formed by repeated episodes of caldera subsidence and resurgence, strongly influenced by regional structure. The Toba depression, and the associated Toba Tuff, a widespread ignimbrite sheet which covers approximately 20.000km, are the result of three major eruptive events.
