The critical role of volcano monitoring in risk reduction [PDF]

open access: yes, 2008
International audienceData from volcano-monitoring studies constitute the only scientifically valid basis for short-term forecasts of a future eruption, or of possible changes during an ongoing eruption. Thus, in any effective hazards-mitigation program,

Evaluation of Pelletized Artificial Geopolymer Aggregate Manufactured From Volcano Ash [PDF]

open access: yes, 2013
This paper introduced the new pelletized artificial geopolymer aggregate made from volcano ash. This is one of the effort to diminish the high quantity of volcano mud from East Java, Indonesia, that become a major issue since May 29, 2006 when it ...

Study on Radioactivity Components, Water Quality and Microstructure Characteristic of Volcano Ash as Geopolymer Artificial Aggregate [PDF]

open access: yes, 2013
The assessments of radioactivity, water quality testing and microstructure characteristic of volcano ash have been examined. The measurement of the 226Ra, 232Th, 40K, and 238U were carried out using radioactive concentration value.

Calcareous Skarn-like Mineral Paragenesis from Unaltered Basalt of the Alaid Volcano (Kuril–Kamchatka Island Arc)

open access: yes
Conditions of high-temperature volcano-related mineral formation are a source of the new and rare minerals and their associations; they are rather fragmentarily described for volcanic systems as a whole, except for several objects characterized in this ...

Magma-Carbonate Interaction at Merapi Volcano, Indonesia

open access: yes, 2023
Merapi volcano, Indonesia, is a highly active arc volcano built upon a crustal succession that includes thick carbonate sequences. Calc-silicate (skarn) xenoliths are frequently found in Merapi’s erupted products and constitute direct evidence for magma ...

Use of a portable topographic mapping millimetre wave radar at an active lava flow. [PDF]

open access: yes, 2006
A ground-based millimetre wave radar, AVTIS (All-weather Volcano Topography Imaging Sensor), has been developed for topographic monitoring. The instrument is portable and capable of measurements over ranges up to ∼7 km through cloud and at night.

The 1723 AD violent Strombolian and phreatomagatic eruption at Irazu volcano (Costa Rica) [PDF]

open access: yes, 2013
The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú. Our reconstruction of the eruption is
