Webinars: „Advancing Frontiers of Geosciences“
International Webinar Series
The KIT international webinar series was established at the beginning of 2021 as an online program with the aim to provide individuals from the KIT Earth and space science community the opportunity to gain comprehensive knowledge on the latest advancements in geoscientific developments without the need of travelling in these uncertain times.
The webinar series will be dedicated to presentations and following discussions on new scientific ideas, exciting research projects, overviews of a geoscientific discipline, and new perspective in geosciences. Internationally acclaimed speakers will share their insights and latest research results. Speakers will be selected to present either disciplinary geoscientific topics or multi- and interdisciplinary topics across many geoscientific disciplines or even transdisciplinary topics across natural and social sciences, engineering, and policymaking. Webinars will also concern scientific challenges related to urgent problems of society, such as alternative sources of energy, environmental changes, and disaster risk reduction.
The webinars will be held monthly during semesters to attract attention KIT faculties, scientists, and students. Normally they will be scheduled on Thursday at 12:00 to 13:30, but the time may be adjusted to allow for speakers from Americas and Asia/Pacific.
The moderator of the webinar series is Dr. Alik Ismail-Zadeh.

Compound and Cascading Hazards:
Typology, Modeling and Risk Assessment
Speaker: Amir AghaKouchak (USA)
Date: 24 June 2021
Time: 9:00–10:30 (note the time!)
Ground-based observations and model simulations show substantial increases in extreme events including rainfall events, droughts, wildfires, hot spells and heatwaves. The first step toward improving our societal resilience is to identify the new patterns of climate extremes and natural hazards. This requires a better understanding of tempo-spatial characteristics of natural hazards and also the interactions between different hazards in a changing climate. A combination of climate events (e.g. high temperatures and high humidity, or low precipitation and high temperatures) may cause a significant impact on the ecosystem and society, although individual events involved may not be severe extremes themselves – a notion known as compound event (e.g. extreme rain over burned areas, combined ocean and terrestrial flooding). Numerous studies have focused on how different types of extremes have changed or might change in the future. However, very few studies have investigated the changing risk of compound and cascading events. This presentation focuses on three different types of compound and cascading events including drought-heatwaves, sea level rise-terrestrial flooding and meteorological-anthropogenic drought. We present different methodological frameworks and perspectives for detecting, modeling and risk assessment of compound and cascading events.
Amir AghaKouchak, Professor of Civil Engineering, Environmental Engineering, and Earth System Science at University of California, Irvine, USA, is among the most creative and productive mid-career geoscientists, and his scholarship, international standing, outreach and service to the community are widely acknowledged. Amir AghaKouchak has published over 170 research papers focusing on hydrology, remote sensing, civil and environmental engineering, water resources, natural hazards, climate change, climate extremes, droughts, floods and compound hazards. He is known for his contributions to analysis and understanding of natural hazards and their societal impacts, including droughts, floods, heat waves and the interactions between inter-related compounds. Amir AghaKouchak is a Fellow of the American Geophysical Union and received several awards and medals including the 2012 Frontiers of Engineering Education Award of the U.S. National Academy of Engineering; the Hydrologic Sciences Early Career Award of the American Geophysical Union (AGU); Early Career Scientist Award of the International Union of Geodesy and Geophysics; AGU James B. Macelwane Medal (for his fundamental and innovative contributions to the study of hydrologic extremes and compound natural hazards) and Walter L. Huber Civil Engineering Research Prize of the American Society of Civil Engineers (for his notable contributions to the science of compound and inter-connected extreme weather events). Currently, Amir AghaKouchak is the Editor-in-Chief of the AGU Earth’s Future journal. Website: http://amir.eng.uci.edu/

Artificial Water Reservoir Triggered Seismicity
Speaker: Harsh Gupta (India)
Date: 20 May 2021
Abstract - Several anthropogenic activities such as gold and coal mining, filling of artificial water reservoirs, geothermal and oil/gas production, high-pressure fluid injection, etc. are known to have triggered earthquakes. Artificial water reservoir-triggered seismicity (RTS) is one of the most prominent among anthropogenic seismicity, with several hundred cases known globally. At least at 5 locations RTS events have exceeded magnitude M 6, causing much damage and claiming human lives. Koyna, India is a very prominent RTS site where earthquakes started soon after the impoundment of the reservoir in 1962, the largest RTS event of M 6.3 occurred on 10 December 1967, and RTS has continued till now (2021). Detailed investigation of RTS sequences has led to the identification of certain characteristics that are common to RTS earthquake sequences and differentiate them from normal (not associated with artificial water reservoirs) earthquakes. In the absence of near field studies, the mechanism of RTS is not well understood. Koyna is found to be a suitable site for such investigations. In collaboration with the International Continental Drilling Program, a 3 km deep Pilot Borehole has been drilled as a precursor to establishing a deep (6 to 7 km) borehole laboratory for the near field study of earthquakes. Salient features of these works are presented in this talk.
Harsh Gupta, Director Emeritus of the National Geophysical Research Institute in Hyderabad, India, is internationally known for his pioneering work devoted to characterizing earthquakes triggered by filling of artificial water reservoirs, discriminating them from normal earthquakes, and developing innovative mitigation procedures. Harsh Gupta has several major contributions on seismic and geodynamic processes at work in the Tibetan Plateau and Himalayan regions, the Bay of Bengal, and the Arabian Sea, as well as on characterization of seismic rupture zones of the Koyna and Latur stable continental regions. Harsh Gupta published over 200 scientific papers and several authored and edited books. Harsh Gupta received several awards, prizes and medals including Waldo E. Smith Medal of the American Geophysical Union and Shanti Swarup Bhatnagar Prize for Science and Technology (India). He is a Fellow of the National Academy of Sciences of India and the Indian National Science Academy. He is currently a Member of the Indian Atomic Energy Regulatory Board, President of the Geological Society of India, and the Editor-in-Chief of the Encyclopedia of Solid Earth Geophysics (Springer). He was a Member of the Indian National Disaster Management Authority chaired by the Indian Prime Minister; Secretary to Government of India, Department of Ocean Development; Vice-Chancellor, Cochin University of Science & Technology; and Professor of the University of Texas at Dallas (USA). He served the International Union of Geodesy and Geophysics as President for 2011–2015.
