Maar-diatreme volcanoes are produced by explosive eruptions that cut deeply into the
country rock. A maar is the crater cut into the ground and surrounded by an ejecta ring, while …

Analytic models for the behavior of gravity currents are discussed, along with observed
displays of the presence of the effect. A current flowing along a horizontal surface is noted to …

Pyroclastic Rocks is the first modern comprehensive treatment of what they are and how
they were formed. The subject is discussed against a background of plate tectonics theory …

Volcanic Hazards: A Sourcebook on the Effects of Eruptions provides a comprehensive
discussion of volcanic eruptions and their effects. This volume provides background data on …

A complex sequence of pyroclastic flows and surges erupted by Nevado del Ruiz volcano
on 13 November 1985 interacted with snow and ice on the summit ice cap to trigger …

Small and large maars exist associated with small and large diatremes, respectively, their
subsurface feeder structures. The problem of size and growth of maar-diatreme volcanoes is …

This review and personal account of basaltic volcanism concentrates on the geological
aspects and physical controls, unlike most others which concentrate on geochemistry. It …

Pyroclasts produced by explosive magma/water interactions are of various sizes and
shapes. Data from analysis of over 200 samples of hydrovolcanic ash are interpreted by …

In the subaqueous growth and emergence of a basaltic volcano clasts are formed by one or
a combination of (1) explosive release of magmatic volatiles;(2) explosive expansion and …

The height reached by a volcanic eruption column, together with the atmospheric wind
regime, controls the dispersal of tephra. Column height is itself a function of vent radius, gas …
