Proceedings of a workshop on Lunar Volcanic Glasses: Scientific and Resource Potential [PDF]

open access: yes
This workshop on lunar mare volcanism was the first since 1975 to deal with the major scientific advances that have occurred in this general subject, and the first ever to deal specifically with volcanic glasses.

A study of stability analysis of pyroclastic covers based on electrical resistivity measurements

open access: yes, 2012
Usually, the degree of stability of a slope is quantified by the Factor of Safety whose values depend on physical and mechanical soil properties analyzed on samples of much reduced sizes or referring to very small soil volumes around porous probes.

Applications of ISES for geology [PDF]

open access: yes
The principal applications for onboard data processing and real-time data transmission in the geological sciences are the detection of early warning signs of potential catastrophic events and the rapid assessment of impact and damage following major ...

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map

open access: yesEarth and Space Science
Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits.

Lava dome collapse causes pyroclastic flows

open access: yesEos, Transactions American Geophysical Union, 1993
Growth of lava domes is common at many volcanos, especially those around the Pacific rim, and the pyroclastic flows associated with these domes constitute one of the most serious of all volcanic hazards. Over thirty‐five scientists from Japanese and U.S. universities and government agencies gathered in Palo Alto, Calif., from March 8–12, to discuss and

An investigation of volcanic depressions. Part 1: Airfall and intrusive pyroclastic deposits. Part 2: Subaerial pyroclastic flows and their deposits [PDF]

open access: yes
Pyroclastic ejecta and the deposits they form were classified in many ways, and many interpretations were given to individual terms. Some classifications are based on the modes of orgin and deposition of the ejecta; others emphasized the chemical and ...

Bright crater outflows: Possible emplacement mechanisms [PDF]

open access: yes
Lobate features with a strong backscatter are associated with 43 percent of the impact craters cataloged in Magellan's cycle 1. Their apparent thinness and great lengths are consistent with a low-viscosity material.

Stratigraphy of the 8.5 – 9.0 ka B.P. Citlaltépetl pumice fallout sequence

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
Citlaltépetl is an active volcano presently in a dormant state, belonging to the easternmost part of the Mexican Volcanic Belt. Although the volcano is characterized by long periods of volcanic repose, some explosive plinian eruptions occurred in ...

Lahars in Java: Initiations, Dynamics, Hazard Assessment And Deposition Processes

open access: yesForum Geografi, 2016
Lahar has been applied as a general term for rapidly flowing, high-concentration, poorly sorted sediment-laden mixtures of rock debris and water (other than normal streamflow) from a volcano.
