A primer for interdisciplinary research on time and future concepts

Thomas Widlok
This document is a "primer". This means that it is meant to prepare projects in the CRC "Future Rural Africa" for discussions on the degree of universality and cultural relativity of future concepts. As a primer it does not provide a conclusion or closure of scholarly debates in the field but its function is to open up and to facilitate these debates. The document consists of two parts. The first, shorter, part is based on...

Gelatin-based analog models simulating dike propagation in the upper crust

Lorenzo Mantiloni, Tim Davis, Ayleen Barbara Gaete Rojas & Eleonora Rivalta
This dataset collects the results of a series of experiments carried out on air-filled cracks injected into pigskin gelatin blocks between September 2019 and May 2020 at GFZ German Research Centre for Geosciences in Potsdam (Germany). Such experiments were intended to simulate dike propagation in the upper crust, in settings where tectonic and surface unloading stress are dominant in determining the stress field within the medium. The gelatin blocks were laterally strained and rift-like excavations...

Laptev Sea Rift Seismological Network (SIOLA) Part I

Wolfram Geissler, Sergey Shibaev, Frank Krüger, Boris Baranov, Christian Haberland, Nikolai Tsukanov, Aline Ploetz, Daniel Vollmer & Sergey Pravkin
The Laptev Sea region is one of the very few places on Earth where mid-ocean spreading centres continue into continental rift zones. The Gakkel Ridge, the active spreading centre in the Eurasia Basin of the Arctic Ocean, is characterized by well-defined seismicity close to its axial graben. In contrast below the Laptev Sea Shelf, which consists of a series of sediment filled grabens (500 km wide, 700 km long), only more diffuse seismic activity is...

Magnetotelluric Study of the Hangai Dome, Mongolia: Phase II

Michael Becken, Alexey V. Kuvshinov, Matthew J. Comeau & Johannes Käufl
Surface deformation in the continental interior, away from active tectonic margins, is enigmatic, with the underlying mechanisms responsible not fully understood. Therefore, it is considered an open and important question in continental dynamics. The Hangai Dome, central Mongolia, is an ideal location to explore this because it is a high-elevation, low-relief, intra-continental region within the Mongolian plateau, between the Siberian and North China cratons, and within the Central Asian Orogenic Belt. The tectonic history of...

Deep electromagnetic sounding for mineral exploration: LOTEM Validation Study 2016

Wiebke Mörbe, Pritam Yogeshwar & Bülent Tezkan
Although the exploitation of strategic important mineral deposits is currently feasible down to a depth of ~ 1000 m, the extension of ore deposits in Germany is poorly known. The BMBF funded DESMEX (Deep Electromagnetic Sounding for Mineral Exploration) project focuses on the development of an electromagnetic exploration system which can be used for the exploration of mineral resources for depths down to 1000 m. The main focus lies in the exploration of potential mineral...

The GNSS co-location experiment at Potsdam

Chaiyaporn Kitpracha, Robert Heinkelmann, Markus Ramatschi, Kyriakos Balidakis, Benjamin Männel & Harald Schuh
The differences of atmospheric delays (Atmospheric ties) are theoretically affected by the height differences between antennas at the same site and the meteorological conditions. However, there is often a discrepancy between the expected zenith delay differences and those estimated from geodetic analysis. The purpose of this experiment is to investigate the possibility effects that could caused biases on GNSS atmospheric delays at co-location site.

Here we present a photogrammetric dataset on the 2018-2019 eruption episode at Shiveluch Volcano, one of the most active volcanoes in Kamchatka Peninsula. The data were acquired by optical sensors and complemented by thermal sensors. The optical satellite images were tri-stereo panchromatic 1-m resolution imagery acquired on 18 July 2018 with Pléiades satellite PHR1B sensor. We processed the data in Erdas Imagine 2015 v15.1. For the relative orientation of the images, 37 tie points were...

HART-La Palma volcanic eruption

Thomas Walter, Torsten Dahm, Simone Cesca, Carla Valenzuela-Malebran, Claus Milkereit, Nicole Richter, Alina Shevshenko, Daniel Vollmer & Marius Kriegerowski
Following a sequence of seismic events detected by the National Geographic Institute (IGN Spain), on 13.09.2021 the new volcano Cumbre Vieja initiated an eruption, located on the mid-western flank at a location just to the north of the 1949 eruption site. The eruption fed a lava flow that buried already some hundreds of houses, with a high economic estimated loss. Previous studies have shown that La Palma was the source of 3 or 4 large...
