Dipartimento di Scienze Ambiente e Territorio e Scienze della Terra Università degli studi di Milano-Bicocca Dottorato di Ricerca in Scienze della Terra XXVI ciclo Earthquake-induced static stress change in promoting eruptions Tutore: Prof. Alessandro TIBALDI Co-tutore: Dott.ssa Claudia CORAZZATO Fabio Luca BONALI Matr. Nr. 040546 This work is dedicated to my uncle Eugenio Marcora who led my interest in Earth Sciences and Astronomy during my childhood Abstract The aim of this PhD work is to study how earthquakes could favour new eruptions, focusing the attention on earthquake-induced static effects in three different case sites. As a first case site, I studied how earthquake-induced crustal dilatation could trigger new eruptions at mud volcanoes in Azerbaijan. Particular attention was then devoted to contribute to the understanding of how earthquake-induced magma pathway unclamping could favour new volcanic activity along the Alaska-Aleutian and Chilean volcanic arcs, where 9 seismic events with Mw ≥ 8 occurred in the last century. Regarding mud volcanoes, I studied the effects of two earthquakes of Mw 6.18 and 6.08 occurred in the Caspian Sea on November 25, 2000 close to Baku city, Azerbaijan. A total of 33 eruptions occurred at 24 mud volcanoes within a maximum distance of 108 km from the epicentres in the five years following the earthquakes. Results show that crustal dilatation might have triggered only 7 eruptions at a maximum distance of about 60 km from the epicentres and within 3 years. Dynamic rather than static strain is thus likely to have been the dominating “promoting” factor because it affected all the studied unrested volcanoes and its magnitude was much larger. -

Field Excursion Report 2010
Presented at “Short Course on Geothermal Drilling, Resource Development and Power Plants”, organized by UNU-GTP and LaGeo, in Santa Tecla, El Salvador, January 16-22, 2011. GEOTHERMAL TRAINING PROGRAMME LaGeo S.A. de C.V. GEOTHERMAL ACTIVITY AND DEVELOPMENT IN SOUTH AMERICA: SHORT OVERVIEW OF THE STATUS IN BOLIVIA, CHILE, ECUADOR AND PERU Ingimar G. Haraldsson United Nations University Geothermal Training Programme Orkustofnun, Grensasvegi 9, 108 Reykjavik ICELAND [email protected] ABSTRACT South America holds vast stores of geothermal energy that are largely unexploited. These resources are largely the product of the convergence of the South American tectonic plate and the Nazca plate that has given rise to the Andes mountain chain, with its countless volcanoes. High-temperature geothermal resources in Bolivia, Chile, Ecuador and Peru are mainly associated with the volcanically active regions, although low temperature resources are also found outside them. All of these countries have a history of geothermal exploration, which has been reinvigorated with recent changes in global energy prices and the increased emphasis on renewables to combat global warming. The paper gives an overview of their main regions of geothermal activity and the latest developments in the geothermal sector are reviewed. 1. INTRODUCTION South America has abundant geothermal energy resources. In 1999, the Geothermal Energy Association estimated the continent’s potential for electricity generation from geothermal resources to be in the range of 3,970-8,610 MW, based on available information and assuming the use of technology available at that time (Gawell et al., 1999). Subsequent studies have put the potential much higher, as a preliminary analysis of Chile alone assumes a generation potential of 16,000 MW for at least 50 years from geothermal fluids with temperatures exceeding 150°C, extracted from within a depth of 3,000 m (Lahsen et al., 2010). -
Appendix A. Supplementary Material to the Manuscript
Appendix A. Supplementary material to the manuscript: The role of crustal and eruptive processes versus source variations in controlling the oxidation state of iron in Central Andean magmas 1. Continental crust beneath the CVZ Country Rock The basement beneath the sampled portion of the CVZ belongs to the Paleozoic Arequipa- Antofalla terrain – a high temperature metamorphic terrain with abundant granitoid intrusions that formed in response to Paleozoic subduction (Lucassen et al., 2000; Ramos et al., 1986). In Northern Chile and Northwestern Argentina this Paleozoic metamorphic-magmatic basement is largely homogeneous and felsic in composition, consistent with the thick, weak, and felsic properties of the crust beneath the CVZ (Beck et al., 1996; Fig. A.1). Neodymium model ages of exposed Paleozoic metamorphic-magmatic basement and sediments suggest a uniform Proterozoic protolith, itself derived from intrusions and sedimentary rock (Lucassen et al., 2001). AFC Model Parameters Pervasive assimilation of continental crust in the Central Andean ignimbrite magmas is well established (Hildreth and Moorbath, 1988; Klerkx et al., 1977; Fig. A.1) and has been verified by detailed analysis of radiogenic isotopes (e.g. 87Sr/86Sr and 143Nd/144Nd) on specific systems within the CVZ (Kay et al., 2011; Lindsay et al., 2001; Schmitt et al., 2001; Soler et al., 2007). Isotopic results indicate that the CVZ magmas are the result of mixing between a crustal endmember, mainly gneisses and plutonics that have a characteristic crustal signature of high 87Sr/86Sr and low 145Nd/144Nd, and the asthenospheric mantle (low 87Sr/86Sr and high 145Nd/144Nd; Fig. 2). In Figure 2, we model the amount of crustal assimilation required to produce the CVZ magmas that are targeted in this study. -
Remobilization of Crustal Carbon May Dominate Volcanic Arc Emissions

Abstract: The flux of carbon into and out of Earth’s surface environment has implications for Earth’s climate and habitability. We compiled a global dataset for carbon and helium isotopes from volcanic arcs and demonstrated that the carbon isotope composition of mean global volcanic gas is considerably heavier, at -3.8 to -4.6 ‰, than the canonical Mid-Ocean-Ridge Basalt value of -6.0 ‰. The largest volcanic emitters outgas carbon with higher δ13C and are located in mature continental arcs that have accreted carbonate platforms, indicating that reworking of crustal limestone is an important source of volcanic carbon. The fractional burial of organic carbon is lower than traditionally determined from a global carbon isotope mass balance and may have varied over geological time, modulated by supercontinent formation and breakup. One Sentence Summary: Reworking of crustal carbon dominates volcanic arc outgassing, decreasing the estimate of fractional organic carbon burial. Main Text: The core, mantle and crust contain 90% of the carbon on Earth (1), with the remaining 10% partitioned between the ocean, atmosphere and biosphere. Due to the relatively short residence time of carbon in Earth’s surface reservoirs (~200,000 years), the ocean, atmosphere and biosphere may be considered a single carbon reservoir on million-year timescales. -

The data compiled from the Cascades and Aleutians are compared to geologic, geochemical and geophysical information from productive volcanic arc centers in the other parts of the world. Seven other volcanic arc segments from around the globe are used in this comparative study. Preliminary findings from data evaluation indicate that there are systematic changes in structural setting, from an extensional influ- ence south of Mt. Hood (in part due to encroachment of the back arc in the southern half) to more compressional north of Mt. Hood. Comparison with productive geothermal fields around the world shows that large fumarolic areas are associated with most >240°C power-producing geothermal systems outside the US arcs (e.g., Kamojang, Indonesia, among others), whereas there is a general absence of large fumarolic areas in the Cascades and Aleutian arcs, aside from of the Lassen volcano area. -
