December 30, 2019 arXiv:1705.09884v2 [physics.geo-ph] 27 Dec 2019 1Corresponding author Abstract By using a very detailed simulation scheme, we have calculated the cosmic ray background flux at 13 active Colombian volcanoes and developed a methodology to identify the most convenient places for a muon telescope to study their inner structure. Our simulation scheme considers three critical factors with different spatial and time scales: the geo- magnetic effects, the development of extensive air showers in the atmosphere, and the detector response at ground level. The muon energy dissipation along the path crossing the geological structure is mod- eled considering the losses due to ionization, and also contributions from radiative Bremßtrahlung, nuclear interactions, and pair production.

  • Magmatic Evolution of the Nevado Del Ruiz Volcano, Central Cordillera, Colombia Minera1 Chemistry and Geochemistry
    Magmatic evolution of the Nevado del Ruiz volcano, Central Cordillera, Colombia Minera1 chemistry and geochemistry N. VATIN-PÉRIGNON “‘, P. GOEMANS “‘, R.A. OLIVER ‘*’ L. BRIQUEU 13),J.C. THOURET 14J,R. SALINAS E. 151,A. MURCIA L. ” Abstract : The Nevado del RU~‘, located 120 km west of Bogota. is one of the currently active andesitic volcanoes that lies north of the Central Cordillera of Colombia at the intersection of two dominant fault systems originating in the Palaeozoïc basement. The pre-volcanic basement is formed by Palaeozoïc gneisses intruded by pre-Cretaceous and Tertiarygranitic batholiths. They are covered by lavas and volcaniclastic rocks from an eroded volcanic chain dissected during the late Pliocene. The geologic history of the Nevado del Ruiz records two periods of building of the compound volcano. The stratigraphie relations and the K-Ar dating indicate that effusive and explosive volcanism began approximately 1 Ma ago with eruption of differentiated andesitic lava andpyroclastic flows and andesitic domes along a regional structural trend. Cataclysmic eruptions opened the second phase of activity. The Upper sequences consist of block-lavas and lava domes ranging from two pyroxene-andesites to rhyodacites. Holocene to recent volcanic eruptions, controled by the intense tectonic activity at the intersection of the Palestina fawlt with the regional fault system, are similar in eruptive style and magma composition to eruptions of the earlier stages of building of the volcano. The youngest volcanic activity is marked by lateral phreatomagmatic eruptions, voluminous debris avalanches. ash flow tuffs and pumice falls related to catastrophic collapse during the historic eruptions including the disastrous eruption of 1985.

Understanding these processes, cataloging their spatio-temporal occurrence, and detecting, tracking, and characterizing these events would advance the science of volcano monitoring and help mitigate hazards. Seismic and acoustic methods show promise for achieving these objectives: many surficial mass movements generate observable seismic and acoustic signals, and many volcanoes are already monitored. Significant progress has been made toward understanding, modeling, and extracting quantitative information from seismic and infrasonic signals generated by surficial mass movements. However, much work remains. In this paper, we review the state of the art of the topic, covering a range of scales and event types from individual rock falls to sector collapses.

Krippner, PhD University of Pittsburgh, 2017 Pyroclastic density currents are volcanic granular flows that include dome collapse-derived block-and-ash flows, and column collapse-derived pyroclastic flows. Volcanic dome-building cycles can last for years and can produce numerous collapse events that deposit block-and-ash flows up to 19 km from the dome. These impact surrounding communities and too-often result in fatalities, and populations have to be evacuated. Shiveluch in Kamchatka, Russia, is one of the world’s most active dome-building volcanoes and has produced some of the largest historical block-and-ash flows, globally.

  • Tracing a Major Crustal Domain Boundary Based on the Geochemistry of Minor Volcanic Centres in Southern Peru
    7th International Symposium on Andean Geodynamics (ISAG 2008, Nice), Extended Abstracts: 298-301 Tracing a major crustal domain boundary based on the geochemistry of minor volcanic centres in southern Peru Mirian Mamani1, Gerhard Wörner2, & Jean-Claude Thouret3 1 Georg-August University, Goldschmidstr. 1, 37077 Göttingen, Germany ([email protected], [email protected]) 2 Université Blaise Pascal, Clermont Ferrand, France ([email protected]) KEYWORDS : minor volcanic centres, crust, tectonic erosion, Central Andes, isotopes Introduction Geochemical studies of Tertiary to Recent magmatism in the Central Volcanic Zone have mainly focused on large stratovolcanoes. This is because mafic minor volcanic centres and related flows that formed during a single eruption are relatively rare and occur in locally clusters (e.g. Andagua/Humbo fields in S. Peru, Delacour et al., 2007; Negrillar field in N. Chile, Deruelle 1982) or in the back arc region (Davidson and de Silva, 1992). These studies showed that the "monogenetic" lavas are high-K calc-alkaline and their major, trace, and rare elements, as well as Sr-, Nd- and Pb- isotopes data display a range comparable to those of the Central Volcanic Zone composite volcanoes (Delacour et al., 2007). It has been argued that the eruptive products of these minor centers bypass the large magma chamber systems below Andean stratovolcanoes and thus may represent magmas that were derived from a deeper level in the crust (Davidson and de Silva, 1992; Ruprecht and Wörner, 2007). This study represents a continuation of our work to understand the regional variation in erupted magma composition in the Central Andes (Mamani et al., 2008; Wörner et al., 1992).
