A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]
, 2011 Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.

Some Studies of New Zealand Quaternary Pyroclastic Rocks [PDF]
, 2021 <p>The development of volcanic "ash" studies in New Zealand can be traced through three broad periods (Jeune 1970). During the late 19th century the extensive pumice deposits surrounding Lake Taupo received considerable comment (Crawford 1875, Smith 1876 and Cussen 1887).

Stiffness of pyroclastic scoriae under different degrees of saturation [PDF]
E3S Web of ConferencesPyroclasts are natural materials formed during volcanic eruptions, characterised by low densities due to their high porosity, which results in reticular, vesicular or mixed internal structures.
