    Description: Abstract
    Description: The ScanArray experiment is a major collaborative effort of institutions in Scandinavia and Germany to map crustal and mantle structure below Scandinavia using a dense temporary deployment of broadband seismometers. Scientific questions to be addressed include (among others): 1. What supports the topographic high of the Scandes? 2. How does lithospheric thickness vary within Fennoscandia? 3. What is the internal fabric of the mantle lithosphere? 4. Are there differences in the crustal structure between the different blocks of Fennoscandia? This data set, termed ScanArray core, comprises the temporary stations deployed by the University of Copenhagen, the University of Aarhus, and the University of Oslo, the Karlsruhe Institute of Technology (KIT) and the GeoForschungsZentrum Potsdam (GFZ) as part of the ScanArray experiment. Stations within this dataset are deployed for periods between 2 and 4 years. Data are available from the GFZ seismological data archive with network code 1G. Waveform data will be fully opened in early 2020. The wider ScanArray dataset additionally includes the multi-use temporary deployments Neonor2 (FDSN-code 2D, University of Bergen, NORSAR) and ScanLips3D (University of Leicester; archived at IRIS DMC), and the permanent networks of Sweden (UP, SNSN), Norway (NS, NNSN), Denmark (DK, DNSN) and Finland (HE, FNSN) as well as a subset of NORSAR stations (NO). The SNSN rearranged the distribution of broadband seismometers and deployed additional temporary stations to meet the objectives of the ScanArray experiment. ScanArray core and these other networks (except ScanLips3D) jointly form the virtual network _SCANARRAY. Partners of the ScanArray consortium are: University of Aarhus, Uppsala University, University of Oslo, University of Bergen, Karlsruhe Institute of Technology, NORSAR, University of Copenhagen, Deutsches GeoForschungsZentrum (GFZ) and Istanbul Technical University.

    Description: Abstract
    Description: A seismological experiment was started in July 2014 in and around the East Eifel Volcanic Field, Germany. Following two unusually deep micro-earthquakes in September 2013 (about 40 km depth) a seismic network was installed to record more local seismic events in order to better understand the seismicity and dynamics of this region. Ten recording stations of the GFZ GIPP (Geophysical Instrument Pool Potsdam at Helmholtz Centre Potsdam, GFZ German Research Centre for Geosciences) and three recording stations of the KIT KABBA (Karlsruhe BroadBand Array at Karlsruhe Institute of Technology) were placed between the permanent stations of the state earthquake survey (Landeserdbebendienst). Altogether about 18-20 short-period and broadband stations could be used to study the seismicity up to August 2016. This dataset is unique concerning the station density in this region and allows determination of hypocenter parameters with high precision and accuracy, estimation of the local crustal and upper mantle structure as well as using array techniques for wavelengths of about 10-50 km. After August 2016 the network was reconfigured and continuously updated by KIT-GPI and LGB. Waveform data is available from the GEOFON data centre, under network code 1P, and is fully open.

    Description: Abstract
    Description: From June 2012 to November 2013, the Chinese Academy of Geological Sciences (CAGS) together with the Deutsches GeoForschungsZentrum Potsdam (GFZ) operated an array of 80 broadband seismic stations in a 300 km by 150 km area straddling the Longmenshan fault zone around the epicentre of the Wenchuan earthquake. Since the occurrence of the Ms 8.0 Wenchuan earthquake which ruptured about 300 km of the Longmenshan fault zone in May 2008, this region has attracted the attention of many Earth scientists. Since the earthquake the Wenchuan Earthquake Fault Scientific Drilling (WFSD) Project has drilled several holes up to 3 km depth. The main purpose of the present array of seismological stations is to investigate the deep structure of the region surrounding the epicentre of the Wenchuan earthquake. While the array was operating the Ms 6.6 Lushan earthquake occurred in April 2013 at the SW edge of the array. Waveform data is available from the GEOFON data centre, under network code 2F, and is embargoed until DEC 2017.

    Description: Abstract
    Description: On 1st April, 23:46:50 UTC, an Mw 8.1 earthquake ruptured offshore northern Chile, near the town of Pisagua northwest of Iquique, followed one day later by a Mw7.6 event, both events in the centre of the Integrated Plate boundary Observatory Chile (IPOC). These earthquakes occurred within a seismic gap left behind by two great earthquakes devastating the northern Chilean and southern Peruvian coast about 140 years ago in 1868 and 1877. The segment inbetween, about 500 km long, was the only one along the Chilean subduction zone that has not ruptured within the last century. The earthquakes were recorded by the IPOC multi-parameter stations plus several additional off-line strong- and weak-motion instruments. A network of GPS monuments covering the onshore region deformed by the earthquake was measured just weeks before the event by GFZ scientists. Taking advantage of the long history of preceding work, presence of the permanent multi-parameter network and excellent knowledge of GFZ scientists of the region, a 20 short-period seismograph network was installed to complement the existing pre- and co-seismic data sets. This campaign was the first case for the „HAzard-Risk-Team (HART)“ initiative of GFZ. Stations operated from mid April 2014, i.e. shortly after the mainshock, to January 2016.

    Description: Abstract
    Description: The temporary Pollino Seismic Experiment, FDSN network code 4A, monitored the earthquake swarm in the Pollino Range region, Italy, between November 2012 and September 2014. The region is located at the transition from the Southern Apennines chain to the Calabrian arc. Striking a volume of about 20x20x15 km, the swarm started in October 2010, culminated in an Mw=5.2 event on 25 October 2012, and has continued since with a variable rate of activity. The area represents a seismic gap as there are no documented historical M〉6 earthquakes during the last thousand years. The tectonic structures of the area are poorly known. The experiment was part of a collaborative effort made by the German Research Centre for Geosciences (GFZ) and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) within the framework of the NERA and CCMP-Pompei projects. The 4A network consisted of 9 stations including 6 short-period and 3 broadband instruments, provided by GFZ. The permanent seismic network was complemented by the 9 GFZ stations and 5 IV stations temporarily installed by INGV. The short-period stations had Mark L-4C3D sensors with EDL digitizers. The broadband stations were equipped with STS2.5 seismometers and RefTek RT130S digitizers. Five short period and one broadband (CSA0 to CSA5) were installed in a small-aperture array in the west of the range. The other three stations (broadband: CSB, CSC and short period: CSD) were installed around the swarm area. The array and the network stations recorded in continuous mode at 200 Hz and at 100 Hz, respectively. The sensors were buried in the ground at 0.5 m depth except for CSB and CSD which were installed on the surface. High-precision station coordinates were obtained by using differential GPS measurements. The data have been used to analyze the earthquakes and seismogenetic structures and to discern the characteristics of the swarm sequence.

    Description: Abstract
    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 Tajikistan aimed to study the seismotectonics of the western Pamir and Tajik-Afghan basin. Within this network 25 seismic stations were deployed between 2012 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 recorded continuously with 100 samples per second and were equipped with EDL (EarthData PR6-24) recorders and broadband seismometers. Waveform data is available from the GEOFON data centre, under network code 5C, and is embargoed until April 2018.

    Description: Abstract
    Description: The integrated plate boundary in Chile (IPOC) combines 15 broadband stations with strong-motion sensors, GPS, strain sensors and magneto-telluric stations. The Chilean subduction zone setting provides a high background rate of seismicity (crustal, intermediate depth, and plate interface) in a region with exceptionally low ambient noise, particularly at higher frequencies. We have deployed seismic mini-arrays in the vicinity of IPOC stations PB02 and PB07, and installed a third array to the east of these stations near the village of Quillagua, such that all three arrays form a triangle. Each array has 10 elements and an aperture in the km range. The study area lies just to the north of the northern boundary of the rupture area of the Tocopilla earthquake of 2007 (Mw=7.7) and just above or slightly to the east of the downdip limit of plate interface seismicity. Installing the mini-arrays in the area of the existing IPOC has the following advantages: * Independent knowledge of background structure and seismicity from existing and ongoing studies. * Should any transients or other unusual signals be found in the array data, we can look for anomalous signals in geodetic and MT recordings, which will help to narrow down possible underlying mechanisms.

    Description: Abstract
    Description: The Etendeka continental flood-basalt province in northern Namibia, linked by the Walvis Ridge to the Tristan da Cunha hotspot, has great importance in global plate tectonic concepts, and is an ideal place to understand the role of the plume-lithosphere interaction during the break-up of the Southern Atlantic Ocean. Within this frame we operated an amphibian passive-source seismic network (WALPASS for Walvis Ridge Passive Source Experiment) in the region where the Walvis Ridge intersects with the continental margin of northern Namibia. The land network operated for over two years while the OBS stations were in operation for one year. The broadband seismic network is composed of 28 three-component land stations and 12 ocean-bottom stations. This configuration of stations will allow us to map the lithospheric and upper mantle structure in the ocean-continent transition beneath the passive continental margin of northern Namibia and to examine possible seismic anomalies related to the postulated hotspot track from the continent to the ocean along the Walvis Ridge. The acquired data should help clarify the velocity anomaly in the lowermost mantle caused by the Africa super plume and to improve the distribution of seismicity in this geophysically little studied region.
