    Description: Abstract
    Description: KivuSNet represents the first dense broadband seismic network installed in the Kivu Rift region, which is located in the bordering region of the Democratic Republic of Congo and Rwanda. Here the active volcanoes Nyamulagira (the most active in Africa) and Nyiragongo (host to the largest persistent lava lake on Earth) threaten the city of Goma and neighbouring agglomerations, and destructive earthquakes can also affect the region. The deployement started with the first stations in 2012/2013 and since October 2015, 13 stations are operated with real-time data transmission. The development of KivuSNet has been carried out in the framework of several research projects and is in particular associated with the project REmote Sensing and In Situ detection and Tracking of geohazards (RESIST), funded by the Belgian Science Policy and the National Research Fund of Luxembourg. KivuSNet aims at opening a new window for the seismological knowledge in this highly active rifting region, allowing for unprecedented insights into tectonic and volcanic seismicity, tremor patterns and Earth structure as well as for sustainable real-time monitoring of the volcanoes in the area. Together with the often co-located KivuGNet geodetic stations, KivuSNet closes a dramatic observational gap in this region. Waveform data is available from the GEOFON data centre, under network code KV. Embargo policy: - All data before 1 August 2019 remain under embargo until 1 August 2024; - Data acquired from 1 August 2019 onwards are opened 3 years after their acquisition, progressively in 1-months batches (e.g. Data from August 2019 would be opened on 1 September 2022, data from September 2019 would be opened on 1 October 2022 etc.) - For any access request to data that are still under embargo, written permission of the RESIST project partners is needed.

    Description: Abstract
    Description: SEG-Y data of small-scale high-resolution controlled-source seismic experiment to investigate the mesoscopic fault structure of the Wadi Arava fault, Dead Sea Transform. The Dead Sea Transform (DST) is a major shear zone running for more than 1000km from the Red Sea in the South to the Zagros mountain chain in the North. It accommodates the lateral movement of the Sinai microplate and the Arabian shield; the total displacement along this shear zone is 〉100km. As part of the DESERT 2000 research project, several geophysical studies on a wide range of scales aimed to reveal the structure and evolution of the DST (Weber et al., 2009, 2010, and references therein). In October/November 2010 we conducted a high-resolution seismic experiment in the central part of the Arava/Araba segment of the shear zone. The analysis of the data (reflection seismics, tomography) revealed the shallow structure of the Wadi Arava fault (main strand of the DST) down to a depth of ~1km. The main findings are published in Maercklin (2004) and Haberland et al. (2007).

    Description: The Geophysical Instrument Pool Potsdam (GIPP) provides field instruments for (temporary) seismological studies (both controlled source and earthquake seismology) and for magnetotelluric (electromagnetic) experiments. The GIPP is operated by the GFZ German Research Centre for Geosciences. The instrument facility is open for academic use. Instrument applications are evaluated and ranked by an external steering board. See Haberland and Ritter (2016) and https://www.gfz-potsdam.de/gipp for more information.

    Description: Abstract
    Description: We carried out a passive seismic experiment formed by 50 broadband and short-period stations with an interstation distance of 3-4 km. These stations were in operation for 22 months, from 06/2013 to 05/2015. The seismic array (TRANSCORBE) was deployed in a linear configuration of 170 km length in a NW-SE direction. The southern edge of the prolife is located near the Mediterranean coast in Mazarrón (Murcia) crossing the Alhama de Murcia fault and the Cazorla Mountain range in the north. The main goal of this project is to study the crustal and upper mantle structures under the Eastern Betics mountain ranges and their variations along the different geological domains. It probes, from southeast to northwest, the Alboran domain (metamorphic rocks), the External zones (sedimentary rocks) and the Variscan terrains of the Iberian Massif. The proposed scientific work includes the analysis of the data using mainly P and S receiver functions, and velocity and attenuation tomographic techniques. The study area has undergone a complex tectonic evolution where slow WNW-ESE oblique convergence of Iberian and African plates coexists with a rapid westward rollback of a subducting slab. The inter-station distance allows us obtaining high-resolution images of the crustal structure essential to understand the tectonic evolution of the area and how the deformation produced by these processes is distributed among the involved geologic domains. This experiment was the results of a joint effort between the Instituto Andaluz de Geofísica (IAG), Granada University, and GFZ Potsdam. Waveform data are available from the GEOFON data centre, under network code 9H and are embargoed until Jan 2021.

    Description: We carried out a passive experiment operated with 10 broadband and short period seismic stations which were installed between July 2013 and May 2015 by a joint effort between the Instituto Andaluz de Geofísica, Granada University and the German Research Centre for Geosciences GFZ. The goal of this project is to study the crustal and upper mantle structures under the Central Betic mountain ranges and the variations of these structures between the different geological domains as a prolongation towards the north of the HIRE profile (Heit, Yuan and Mancilla; 2010). Waveform data is available from the GEOFON data centre, under network code 3J.

    Description: Abstract
    Description: The TIPTIMON seismic deployment in Afghanistan aimed to study the seismotectonics of the Hindu Kush and the Tajik-Afghan basin. Within this network 8 seismic stations were deployed between 2013 to 2014 to study shallow and intermediate depth seismicity. TIPTIMON (Tien Shan-Pamir Monitoring) is a research programme funded by the German Federal Ministry of Education and Research (BMBF) within the CAME Programme (Central Asia - Monsoon dynamics and Geo-ecosystems). All stations were equipped with MARK L-4C-3D geophones and DSS CUBE recorders, continuously recording with 100 samples per second. Waveform data is available from the GEOFON data centre, under network code 6C, and is embargoed until Oct 2018.
