🌍 The World Stress Map (WSM) is a global compilation of information on the crustal present-day stress field maintained since 2009 at the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences within Section 2.6 Seismic Hazard and Risk Dynamics. 🤝 It is a collaborative project between academia and industry that aims to characterize the crustal stress pattern and to understand the stress sources. 🚀 The WSM commenced in 1986 as a project of the International Lithosphere Program (ILP) under the leadership of Mary-Lou Zoback. 🎓 From 1995-2008 it was a project of the Heidelberg Academy of Sciences and Humanities headed by Karl Fuchs and Friedemann Wenzel. Since 2012 the WSM is a member of the ICSU World Data System. 📊 All stress information is analysed and compiled in a standardized format and quality-ranked for reliability and comparability on a global scale. 📈 The latest WSM database release 2016 contains 42,870 data records within the upper 40 km of the Earth’s crust. The WSM is an open-access public database and is used by various academic and industrial institutions working in a wide range of Earth science disciplines such as geodynamics, hazard assessment, hydrocarbon exploitations and engineering. 🔧 The main operational areas are Reservoir characterization and management. Source from Helmholtz-Centre Potsdam - German Research Centre GFZ : https://lnkd.in/dGTFAJSE Picture: World Stress Map 2016 | The stress map shows the orientation of maximum horizontal stress SHmax in the Earth's crust (Heidbach et al. 2016). Symbols denote the SHmax orientation from various stress indicators. Colours denote the stress regime: normal faulting (NF), strike-slip (SS), thrust faulting (TF) and unknown (U).

Im Rahmen unseres Forschungsseminars "Economic History, Growth and Development" stellen wir euch den folgenden Gastvortrag vor: Herr Prof. Jörg Baten spricht zum Thema: "So many insights- New archaeological and big data strategies for long-term economic studies of the past 12,000 years" Termin: Mittwoch, 08. Mai 2024, 18:00 - 19:30 Uhr Ort: Wirtschaftswissenschaftliche Fakultät, Seminarraum 1, Große Steinstraße 73, 06108 Halle (Saale) This lecture's topic will be the emergence and evolution of corporate governance. It focuses on the Toulouse Mills which are early exemplars of joint-stock corporations that thrived for approximately six centuries, starting from the Middle Ages onward. Based on extensive archival sources, notably a comprehensive Renaissance corporate statute, the studies uncover a governance structure that, despite its medieval origins, exhibits striking similarities with current shareholder-oriented governance including tradable shares, limited liability, governing boards, external audits, and shareholder meetings. They also describe some unique governance features including a unique board functioning and a “no-free cash flow” policy. These findings offer insights into ongoing debates surrounding financial history, comparative corporate governance, and institutional economics (Prof. Dr. Lars Börner).

Here are some great examples showing basic seismic velocity concepts. The examples are from Wakeel Ur Rehman; see below. Assume no anisotropy. The top/left shows a synthetic representation of layered geology. There are 5 formations; seismic velocity increases with each deeper layer. You can see source/receiver pairings at the top, from near offset to far offset. Direct raypaths are shown, but in actuality they would bend across the boundaries (look up Snell’s Law). The top/right shows the 4 seismic reflection events as they would appear in a gather of individual source/receiver pairs. Source-to-receiver offsets increase to the right and 2-way time increases to the bottom. The 4 reflections are shown curving down at farther offsets because it takes more time for far offset reflections to be recorded than near offset reflections (increased travel distance). The bottom/left image is the top/right image repeated. The bottom/middle shows the velocity semblances for this gather. Velocity increases to the right and the vertical time scale is unchanged. The yellow dots show optimal stacking velocities for each reflector. Note how deeper events show faster velocities than shallower events. The bottom/right shows what happens to the gather’s events after applying the correct velocities (applying nmo or normal moveout). The events are now flat for all offsets. The amplitudes would be added horizontally across this gather (i.e. stacked), then placed at one geographic location. There are many such gathers in modern seismic surveys. https://lnkd.in/ggRZjxGV * Interested in a seismic training class for your organization?

#GEOPHYSICS: 𝗣𝗶𝗼𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗘𝗮𝗿𝘁𝗵𝗾𝘂𝗮𝗸𝗲 𝗮𝗻𝗱 𝗧𝘀𝘂𝗻𝗮𝗺𝗶 𝗙𝗼𝗿𝗲𝗰𝗮𝘀𝘁𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗙𝗶𝗯𝗿𝗲-𝗢𝗽𝘁𝗶𝗰 𝗡𝗲𝘁𝘄𝗼𝗿𝗸𝘀 𝗮𝘁 𝗟𝗼𝘄 𝗖𝗼𝘀𝘁 A revolutionary method for earthquake and tsunami forecasting has been developed by Dr. Andreas Fichtner at ETH Zürich and a team of experts from the Swiss Federal Institute of Metrology (METAS). This groundbreaking approach harnesses the power of existing fibre-optic infrastructure to measure minimal pressure changes at monumental depths, significantly improving the accuracy of seismic event forecasting. Their technique has demonstrated the ability to precisely pinpoint an earthquake's location, depth, and magnitude, facilitating comprehensive tsunami warnings and enhancing earthquake detection in less developed regions. This innovative initiative, which originated in a conversation between ETH and METAS specialists, was made possible by ETH's funding for independent research and is set to redefine our understanding of seismology. 👉 Learn more >> https://lnkd.in/eeSz-H7K #EarthquakeDetection #ETHZurich #SwissFederalInstituteOfMetrology #METAS #FibreOptic #Seismology Science-Switzerland Follow the Consulate of Switzerland, Swissnex in Japan🇨🇭🇯🇵 #AddingValue | #Education | #Research | #Innovation | #Startups🚀 | #VitalitySwiss

Tomorrow (June 18th) is the deadline for submitting abstracts to present research at GSA this fall in Anaheim! If you are working on faults and looking for a place to discuss geological and geophysical constraints on fault zone characteristics and processes, consider submitting an abstract to our session, T61 (full details below); it is tied to the Woollard Award (G&G division), but there is no need to have a direct tie to the awardee, as it is a general session. We are hoping that given the meeting location in Anaheim that there will be a good crowd interested in faults. Hope to see you in Anaheim this fall! Full session details: Session T61. Woollard Session: Interdisciplinary Insights into Fault Zone Properties and Faulting Processes Discipline Endorsers: GSA Geophysics and Geodynamics Division Session Chairs: Anjana Shah, Shannon Dulin, Amanda Hughes, and Ting Chen Session Description: In the spirit of 2023 Woollard Awardee Mian Liu's research, we invite contributions centered on the theme of interdisciplinary observational, theoretical, and numerical modeling studies of faults and fault zones.
