Calderas are oval fault-bounded depressions in volcanic regions. The formation of a small
analog, a summit pit-crater, has followed a ten-month cycle of eruptive activity at Piton de la …

Summit explosive activity and collapses that form pit craters and calderas represent major
volcanic hazards on a dominantly effusive, frequently active volcano like Piton de la …

In the present episode of eruptive activity, evidence from seismicity for sustained magma
inflow from depth into the edifice of Piton de la Fournaise is lacking. Pre-eruptive main …

The short eruption of June 14–15 1985 was the beginning of an important cycle of activity of
Piton de la Fournaise that lasted more than two years and comprised twenty or so eruptive …

We explore the possible relationships between a structural heterogeneity, the hydrothermal
system, and the intrusive activity at Piton de la Fournaise volcano. Geological and …

Collapse calderas are frequent in the evolution of volcanic systems, but very few have
formed during historical times. Piton de la Fournaise is one of the world's most active …

An eruption on the eastern flank of Piton de la Fournaise volcano started on 16 November,
2002 after 10 months of quiescence. After a relatively constant level of activity during the first …

Abstract Piton de la Fournaise (La Réunion Island) is a very active, primarily effusive ocean-
island volcano. The Bellecombe Tephra represents at least three explosive eruptions that …

Based upon a re-interpretation of previous data and a new field campaign, a structural
evolution is proposed for the early history of Piton de la Fournaise volcano from 500,000 to …

On April 5th 2007, a major collapse of the Dolomieu summit crater occurred at Piton de La
Fournaise volcano (La Réunion Island). To constrain the origin and the dynamics of the …
