The Materials Failure Forecasting Method for volcanic eruptions (FFM) analyses the rate of
precursory phenomena. Time of eruption onset is derived from the time of “failure” implied by …

Thick silicic volcanic ash layers commonly observed hundreds of kilometres from potential
source areas have resulted from large-magnitude explosive eruptions that have no historical …

In order to evaluate the activity of the Hawaiian hot spot, we calculate both the magma
production rate, associated with volcanism, and the rate of swell formation, characteristic of …

A simple model is developed to relate the maximum down-wind and cross-wind ranges of
pyroclasts forming a plinian airfall deposit to the dynamic processes in the eruption cloud …

Explosive volcanic eruptions propel high-velocity turbulent jets into the atmosphere and are
one of the most powerful and dangerous turbulent flows on Earth. Such eruptions are …

Hawaiian eruptions are largely random phenomena displaying no periodicity; that is, future
eruptions are relatively independent of the date of the last eruption. Several simultaneous …

Since its reactivation in 1988 the principal eruptions of Galeras Volcano occurred on May 4–
9, 1989, July 16, 1992, and January 14, March 23, April 3, April 14 and June 7, 1993. The …

A classification scheme is proposed based on measurements made on the resulting
pyroclastic fall deposits, the significant parameters being the area of dispersal and degree of …

The 1949 rift zone eruption along the Cumbre Vieja ridge on La Palma involved three
eruptive centers, 3 km spaced apart, and was chemically and mineralogically zoned …

Eruptive column models are powerful tools for investigating the transport of volcanic gas and
ash, reconstructing past explosive eruptions, and simulating future hazards. However, the …
