Skilling, Assistant Professor, University of Pittsburgh ii Copyright © by Adam Joseph Carter 2008 iii QUANTITATIVE THERMAL INFRARED ANALYSES OF VOLCANIC PROCESSES AND PRODUCTS: APPLICATION TO BEZYMIANNY VOLCANO, RUSSIA Adam Joseph Carter, BSc, DEA University of Pittsburgh, 2008 Bezymianny (55.98°N, 160.59°E) is a Holocene andesitic composite volcano with a summit elevation of approximately 2,900 m and is located on the Kamchatka Peninsula, eastern Russia. Previously inactive for about 1,000 years, Bezymianny reactivated in 1955, culminating in a cataclysmic eruption on 30 March 1956. This directed blast generated a 1.3 km (north–south) by 2.8 km (east–west) horseshoe shaped crater opening to the east, similar in morphology and activity to Mt. St. Helens (USA). During the last 30 years Bezymianny has been regularly active, erupting one to two times per year on average. This work focuses on field-based and remote sensing observations of explosive eruptions and their products at Bezymianny, concentrating on the pyroclastic flow (PF) deposits on the southeast flank. The events of March 2000, January 2005, December 2006, May 2007 and October 2007 were focused on to elucidate information on the pyroclastic flow (PF) deposits that were emplaced. Two principal themes were addressed: (1) A thermal infrared (TIR) investigation of the eruptive events and products. This encompassed ground-based field work, Forward Looking Infrared Radiometer (FLIR) image data, and spaceborne data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). (2) A micrometer-scale textural investigation of vesicular block and ash samples collected in the field on the pyroclastic flow deposits. Scanning Electron Microscope (SEM) iv images were used to generate micron-scale digital elevation models (DEM) for the surfaces of each volcanic sample collected. These were compared to TIR emission spectra that were deconvolved to estimate surface vesicularity. This work demonstrates the utility of TIR observations from satellite, aerial, and ground-based data that, in combination with standard geological mapping, provide timely, accurate, and quantitative remote sensing data to assist in the prediction and monitoring of explosive volcanoes. v TABLE OF CONTENTS PREFACE.................................................................................................................................

  • Weathering of Volcanic Ash in the Cryogenic Zone of Kamchatka, Eastern Russia
    Clay Minerals, (2014) 49, 195–212 OPEN ACCESS Weathering of volcanic ash in the cryogenic zone of Kamchatka, eastern Russia 1, 2 E. KUZNETSOVA * AND R. MOTENKO 1 SINTEF Building and Infrastructure, Trondheim, NO-7465, Norway, and 2 Lomonosov Moscow State University, Moscow, 119991, Russia (Received 8 August 2012; revised 28 August 2013; Editor: Harry Shaw) ABSTRACT: The nature of the alteration of basaltic, andesitic and rhyolitic glass of Holocene and Pleistocene age and their physical and chemical environments have been investigated in the ash layers within the cryogenic soils associated with the volcanoes in the central depression of Kamchatka. One of the main factors controlling the alteration of the volcanic glass is their initial chemistry with those of andesitic (SiO2 =53À65 wt.%) and basaltic (SiO2 < 53 wt.%) compositions being characterized by the presence of allophane, whereas volcanic glass of rhyolitic composition (SiO2>65 wt.%) are characterized by opal. Variations in the age of eruption of individual ashes, the amount and nature of the soil water, the depth of the active annual freeze-thawing layer, the thermal conductivity of the weathering soils, do not play a controlling role in the type of weathering products of the ashes but may affect their rates of alteration. KEYWORDS: volcanic ash, allophane, opal, unfrozen water, thermal conductivity, permafrost, Kamchatka. The highly active volcanic area of Kamchatka in local and remote eruptions and from the secondary eastern Russia is part of the circum-Pacific belt of re-deposition of ash (Bazanova et al., 2005). andesitic volcanism. It is situated north of the 49th Considerable research has been carried out on the parallel of latitude and is characterized by a weathering of volcanic glass.

  • Thermal Remote Sensing Reveals Communication Between
    www.nature.com/scientificreports OPEN Thermal remote sensing reveals communication between volcanoes of the Klyuchevskoy Volcanic Group Diego Coppola1,2*, Marco Laiolo1,2, Francesco Massimetti1,3, Sebastian Hainzl3, Alina V. Shevchenko3,4, René Mania3, Nikolai M. Shapiro5,6 & Thomas R. Walter3 Volcanoes are traditionally considered isolated with an activity that is mostly independent of the surrounding, with few eruptions only (< 2%) associated with a tectonic earthquake trigger. Evidence is now increasing that volcanoes forming clusters of eruptive centers may simultaneously erupt, show unrest, or even shut-down activity. Using infrared satellite data, we detail 20 years of eruptive activity (2000–2020) at Klyuchevskoy, Bezymianny, and Tolbachik, the three active volcanoes of the Klyuchevskoy Volcanic Group (KVG), Kamchatka. We show that the neighboring volcanoes exhibit multiple and reciprocal interactions on diferent timescales that unravel the magmatic system’s complexity below the KVG. Klyuchevskoy and Bezymianny volcanoes show correlated activity with time-predictable and quasiperiodic behaviors, respectively. This is consistent with magma accumulation and discharge dynamics at both volcanoes, typical of steady-state volcanism. However, Tolbachik volcano can interrupt this steady-state regime and modify the magma output rate of its neighbors for several years. We suggest that below the KVG the transfer of magma at crustal level is modulated by the presence of three distinct but hydraulically connected plumbing systems. Similar complex interactions may occur at other volcanic groups and must be considered to evaluate the hazard of grouped volcanoes. Closely located or clustered volcanoes may become conjointly active and are hence considered especially haz- ardous, yet robust evidence for their connectivity remains sparse.

Tephra layers produced by volcanic eruptions are widely used for correlation and dating of various deposits and landforms, for synchronization of disparate paleoenvironmental archives, and for reconstruction of magma origin. Here we present our original database TephraKam, which includes chemical compositions of volcanic glass in tephra and welded tuffs from the Kamchatka volcanic arc. The database contains 7049 single-shard major element analyses obtained by electron microprobe and 738 trace element analyses obtained by laser ablation inductively coupled plasma mass spectrometry on 487 samples collected in close proximity to their volcanic sources in all volcanic zones in Kamchatka. The samples characterize about 300 explosive eruptions, which occurred in Kamchatka from the Miocene up to recent times.
