This paper, summarising and evaluating regional data of recent research, focusses on the characteristics of erosion and drainage pattern observed on the youngest to oldest volcanic depressions of the Carpathians. Eroded craters, calderas, failure
The AA. present the geological and volcanic setting of the Misti volcano which encompasses 2 edifices : the old Misti stratovolcano and the young Misti stratocone. They analyze the stratigraphy and the chronology of its eruptive activity
, in particular over the past 100,000 years : 7 compound groups of deposits record the late Pleistocene eruptive of the modern Misti stratocone. Then, they aim to assess the volcanic hazards of future eruptions at Misti, based on mapping, recent eruptive deposits
, and models used on similar stratovolcanoes : 700,000 people in the Arequipa-Chiguata region are threatened by at least 4 types of volcanic hazards.

Sediment discharge including debris flows generated by storm runoff during, or just after volcanic eruptions can bring about severe disasters downslope on the flanking alluvial fans. In many cases, the main cause of such disasters is a major change
in the hydrologic response of the slope from the eruption. Observation of sediment discharge at 3 volcanic torrents at Mount Unzen and Mount Yakedake in Japan, and Mount Merapi in Indonesia, provided insight to such processes at volcanoes with recent eruption
The aim of this paper is to single out the relationships among the present landforms, their structural arrangement and the volcanic history of Central Italy. The morphological characteristics of the Roccamonfina volcano were examined through field
