    Archaeoseismology – Earthquake damage in Machu Picchu

    A recent study presented at the GSA meeting concludes that the UNESCO World Heritage site of Machu Picchu in Peru was intentionally built on faulted bedrock in order to ease the quarrying of the huge blocks used as construction material (Menegat, 2019). But has Machu Picchu seen big earthquakes in its lifetime? And if so, can it tell us something about their magnitude? After all, there are plenty of earthquakes in Peru, not only at the subduction zone but also in the Andes (e.g., Wimpenny et al., 2018). Some strong instrumental events occurred less than 100 km away from the Inca site. However, in the area of Machu Picchu we knew little about strong earthquakes. That’s why in 2016 a group of researchers from Peru, France, and the UK including myself started to investigate the active faults around Cusco and archaeoseismological damage to Machu Picchu and other famous Inca sites nearby in the CUSCO-PATA project.

    New papers on paleoseismology, earthquakes, and active tectonics (Dec 2019)

    Shopping is stressful, reading new papers is exciting. Why not lean back in your favourite comfy chair, enjoy a hot tea and see what’s new in paleoseismology and related fields? These are the latest papers on paleoseismology, earthquakes, and active tectonics.

  • When the fault rings twice: repeated ruptures on the same fault stretch

    The recent publication of a paper on the Weitin Thrust (Papua New Guinea) by Chen, Milliner and Avouac (Fig. 1) gave me the opportunity to dig out and look back to some notes I wrote few months ago. Chen et al. use optical image correlation to document coseismic surface ruptures along the Weitin Thrust occurred in a Mw 8.0 event in 2000 and in a Mw 7.7 event in 2019. The ruptures overlap along a 20-km long portion, with 3-4 m of slip (Fig. 2).

    Quaternary sea-level change along the coastline of Oman

    Text: Gösta Hoffmann with contributions by Michaela Falkenroth, Valeska Decker, Bastian Schneider and Christoph Grützner

    The beaches in Oman are pristine.” What sounds like an introductory sentence to a tourist brochure has scientific significance. Natural conditions without anthropogenic overprint are characteristic for vast stretches along the 1700 km coastline of Oman from the Strait of Hormuz in the north to the border of Yemen in the south. This situation allows geological research addressing Quaternary sea-level change on various timescales spanning from minutes to millennia. Over the last couple of years, we carried out research funded by the Omani Government and the German Research Foundation (DFG). Our findings are currently published in a series of papers (Schneider et al. 2018; Ermertz et al. 2019; Falkenroth et al. 2019, subm.; Hoffmann et al. 2020a, b) and are briefly summarised here.

    New papers on paleoseismology, earthquakes, and active tectonics (Nov 2019)

    Today we have a number of studies on “classic” paleoseismology, but also a fair share of tsunami and historical seismicity/archaeoseismology research. Plus, some very interesting papers on methods and concepts. Not to forget the first one in the list that presents an extremely useful surface rupture database. I may write a long blog post on this one, soon. Enjoy reading!

    This was the INQUA Summer School on Active Tectonics and Tectonic Geomorphology in Prague

    The INQUA Summer School on Active Tectonics and Tectonic Geomorphology was held in Prague from 24-27 September, 2019. This summer school was run by INQUA‘s IFG EGSHaz as part of the TERPRO commission. The event was hosted by the Institute of Rock Structure and Mechanics, Academy of Sciences of the Czech Republic, Dpt. Neotectonics and Thermochronology. Main organizer was IFG co-leader Petra Štěpančíková. We would also like to thank MSc. Jakub Stemberk, Monika Hladká, Jana Šreinová, the deputy director Dr. Filip Hartvich, and all the staff involved for their professionalism and warm hospitality. Overall, 50 participants and 14 lecturers from 25 countries participated in the summer school.

  • We mourn the passing of Prof. Dr. Victor Hugo Garduño Monroy

    Dear colleagues,

    It is with great sadness that we received note from the passing of our dear colleague Victor Hugo Gorduño Monroy.

    Victor was a close friend to many of us and an outstanding person in the Mexican scientific community. He authored a great number of publications on the geology of Mexico, on tectonics, volcanism, and hazards. His work did not only advance geosciences, but also had huge impact on society. He was tireless in helping to raise the awareness for disasters and to promote geoscience in the public. We will never forget his enthusiasm and his dedication in the field.

    He had the leading role in geosciences at the Michoacan University of San Nicolás de Hidalgo and taught hundreds of students during his career.

    Victor organized the first PATA days outside Europe in November 2012 in Morelia in commemoration of the 1912 Acambay Earthquake, which was an absolute pleasure and a great success.

    Our thoughts are with his family and with everyone who worked closely with him.

    The Michoacan University of San Nicolás de Hidalgo released the following letter of condolence:

    El día de hoy sufrimos la pérdida de una de nuestras más sólidas columnas institucionales. Informamos con profunda tristeza que el Dr. Víctor Hugo Garduño Monroy falleció esta mañana y con él perdimos a nuestro Líder Académico y Fundador de la Maestría en Geociencias y Planificación del Territorio y del Instituto de Investigaciones en Ciencias de la Tierra. El Dr. Garduño fue un incansable investigador de la Geología de nuestro Estado y del Occidente de México. Formador profesional de centenares de estudiantes a nivel profesional y posgrado. Ganador de la Presea José María Morelos y Pavón y Primer Investigador en Obtener la Presea Vasco de Quiroga en nuestra querida Universidad Michoacana de San Nicolás de Hidalgo. Hoy se fue uno de los mejores investigadores de nuestra Universidad, de nuestro Estado y de nuestro País. Siempre será recordado por el cariño a su profesión, a sus estudiantes y compañeros. Descanse en Paz.
