“Triggered Seismic Activity in Geothermal Regions and Along Strike-Slip Faults of the Western Hemisphere”
Abstract:
Dynamic stresses caused by large earthquakes are capable of triggering a wide range of seismic/aseismic responses at remote distances. These responses include instantaneously triggered microearthquakes, deep tectonic tremor, earthquake swarms, slow-slip events, and near-surface icequakes. Systematic studies of these triggered phenomena not only help us to understand how large earthquakes affect seismic/aseismic processes at remote distances but also help improve our understanding of the necessary physical conditions responsible for the generation of seismic activity. In this talk I present two recent studies: (1) a comparison of triggered microearthquakes in three geothermal regions of California and (2) a comparison of triggered tremor on four strike-slip faults in the Western Hemisphere. Triggered seismic activity is characterized as being triggered by the surface waves of large, distant earthquakes. Triggered earthquakes in geothermal regions are generally small magnitude (M<4) and have distinct P and S waves, whereas triggered tremor is a low-amplitude, emergent signal with no distinct P wave. After identifying the large earthquakes that trigger seismic activity, we analyze and compare the peak ground velocities, seismic wave incidence angles, amplitude spectra of all distant earthquakes we examined, as well as the background activity in each region to determine the factors that promote triggering in geothermal regions and on strike-slip faults.
DeFord Lecture | Dr. Richard TaylorApril, 25 2024Time: 4:00 PM - 5:00 PMLocation: Boyd Auditorium (JGB 2.324) Adapting to the Amplification of Climate Extremes Through Freshwater Capture: Evidence from the Tropics by Dr. Richard Taylor, Department of Geography, University College London Abstract: In low-income countries of the tropics undergoing rapid growth, global warming presents challenges to the expansion and sustainability of water supplies required to advance progress toward the United Nations’ Sustainable Development Goals. Substantial uncertainty persists in projections of precipitation under climate change. A widely observed impact, pronounced in the tropics, is the intensification of precipitation comprising a transition towards fewer but heavier rainfalls. How does this transition impact terrestrial water balances? How might these changes influence freshwater demand? I will interrogate these questions and review mounting empirical evidence from the tropics of the resilience to climate change of groundwater resources, which act as a natural inter-annual store of freshwater supporting adaptation to the amplification climate extremes. Presented evidence includes case studies and local-to-regional scale analyses from tropical Africa and the Bengal Basin of South Asia. Outcomes emphasize the interconnected nature of surface water and groundwater as well as the value of groundwater as a natural, distributed store of freshwater. This insight provides a platform to explore more equitable and sustainable water development pathways resilient to climate change. |
UTIG Seminar Series: Cornelia Rasmussen, UTIGApril, 26 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Cornelia Rasmussen, Research Associate, University of Texas Institute for Geophysics Host: Krista Soderlund Title: The Emerging Field Of Position-Specific Isotope Analysis: Applications in chemical forensics, exobiology, geo- and environmental sciences Abstract: Complex organics can be found all over our solar system and within each living thing on our planet, be it as part of its physiology or as a contaminant. However, different processes can lead to the formation of chemical identical molecules. This makes answering a number of scientific questions challenging. One example is distinguishing between biotic and abiotic molecules, hence hindering life detection on early Earth but especially on other planetary bodies, such as on Mars, Titan, Enceladus and on meteorites where organics have been detected. Moreover, tracing molecules as they move through the environment can be demanding, yet is essential in studying the flow of organic molecules as well as correlating pollutants with their source. Novel tools to address these challenges are currently being developed. Especially, the emerging field of position-specific isotope analysis is beginning to grant access to the unique intramolecular carbon (13C/12C) isotope fingerprint preserved in complex molecules. This fingerprint can be applied in various scientific disciplines, ranging from forensics to exobiology, geo- and environmental sciences, including geo health. Nuclear magnetic resonance spectroscopy (NMR) has the potential to become a key player in this research area, as it allows the analysis of organics within complex mixtures, all without the need to fragment the molecule into single carbon units or the combustion of the molecule of interest. We have been developing several NMR tools that allow us to investigate the intramolecular carbon isotope distribution within various molecule classes and to test the central hypothesis that the position-specific carbon isotope distribution within complex organics depends on a molecule’s source and formation history. |
