This study compares and evaluates one-dimensional (1D) and three-dimensional (3D)
numerical models of volcanic eruption columns in a set of different inter-comparison …

We have measured grain size distributions of the results of laboratory decompression
explosions of volcanic rock. The resulting distributions can be approximately represented by …

Volcanic Ash: Hazard Observation presents an introduction followed by four sections, each
on a separate topic and each containing chapters from an internationally renowned pool of …

Since the 1970s, multiple reconstruction techniques have been proposed and are currently
used, to extrapolate and quantify eruptive parameters from sampled tephra fall deposit …

The maximum height of an explosive volcanic column, H, depends on the 1/4th power of the
eruptive mass flux, Q, and on the 3/4th power of the stratification of the atmosphere, N …

We carry out a parametric study in order to identify and quantify the effects of uncertainties
on pivotal parameters controlling the dynamics of volcanic plumes. The study builds upon …

The proximal Plinian fall deposits of the Campanian Ignimbrite (CI; 38 ky, Fedele et al.,
2008) and Pomici di Base (PdB; 18 ky, Bertagnini et al., 1998) have been investigated in …

This PhD thesis focuses on numerical and analytical methods for simulating the dynamics of
volcanic ash plumes. The study starts from the fundamental balance laws for a multiphase …

The Upper Jurassic Emuerhe Formation was developed with abundant sedimentary facies
types in the western section of the Mohe Basin. Based on the systematic sampling and …

The Laki 1783-4 fissure eruption was a devastating time for Iceland. It featured 10 separate
eruption episodes and two of them were phreatomagmatic. The phreatomagmatic (P1) …
