Geology, Archaeology, and Historical Studies of the Late 16th Century Plinian Eruption of Raung Volcano: A Potential Case for Disaster Geotourism in Ijen UNESCO Global Geopark, East Java, Indonesia

Geosciences
The enigmatic major eruption in the late 16th century, believed to have originated from Raung, the most active stratovolcano in the Ijen UNESCO Global Geopark in East Java, Indonesia, has ignited significant debate among researchers and historians due to

The ad 79 Vesuvius eruption revisited: the pyroclastic density currents

Journal of the Geological Society
Seventeen pyroclastic density currents (PDCs) were produced before, during and after the Plinian phase of the ad 79 eruption of Vesuvius. Their deposits were correlated using the proportions of components, together with the recognition of distinctive intercalated regionally traceable fall marker layers, revealing ...

Evaluation of topographic effects on infrasonic array observation toward the source elevation estimation

Earth, Planets and Space
The infrasonic array technique is applied in many volcanoes to locate the acoustic source. Compared to the azimuthal estimation for the horizontal source location information, the elevational estimation is challenging due to the difficulty of aligning ...

Research in volcanic geology, petrology and planetary science at MIT, 1969 to 1974 [PDF]

The behavior of volcanoes was studied by geologic mapping, petrologic investigations of lava and xenoliths, physical measurements, and theoretical modelling. Field observations were conducted in Alaska (Nunivak Island), Iceland, Hawaii (Mauna Kea), Italy

Analogue modelling of pyroclastic density current deposition

, 2010
A series of analogue flume experiments are used to investigate initiation, flow and deposition of static piles of polymict materials, the sorting during transport, and the three dimensional geometry of the resulting deposits. Sequential charges are used to investigate the effects and extent of reworking.
