Ruang Volcano Eruption Update; Estimating the Eruption's Size

Between April 16th & April 30th, the Ruang volcano produced a destructive eruption which was larger than the 1980 eruption of Mt. St. Helens. Yet, how exactly did I estimate that 1.40 cubic kilometers of tephra was ejected? In this video I will answer that question and discuss how the amount of magma which feeds an eruption does not have the same volume as the tephra it ejects.
