Subsidence of ash-flow calderas: Relation to caldera size and magma-chamber geometry
TL;DR: In this paper, a review of features at eroded pre-Quaternary calderas is inferred to reflect varying sizes, roof geometries, and depths of the source magma chambers, in combination with prior volcanic and regional tectonic influences.

Yoko Ota,Akio Omura +1 more
TL;DR: The recent progress of late Quaternary shoreline studies in Japan are reviewed in this paper, where outcomes of the estimation of ages and elevations of shorelines during high sea-level stand of the late Pleistocene are exemplified for five localities, Hateruma Island in the Ryukyus, Matsumae Peninsula of Hokkaido, Tanegashima Island to the south of Kyushu, Noto Peninsula in the Japan Sea side of Chubu district, and Muroto Peninsula of southeastern Shikoku.

Preferred Clast Orientation in Volcaniclastic Mass-Flow Deposits: Application of a New Photo-Statistical Method
TL;DR: A photo-statistical method has been developed to quantify the strength of directional clast fabric in various types of volcaniclastic mass-flow deposits as mentioned in this paper, which is defined as the resultant vec- tor length of clast alignment computed from clast angles visible on a vertical outcrop face.
