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...

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...

Myanmar subduction to collision imaging array (MySCOLAR)

Frederik Tilmann, Bernd Schurr, Xiaohui Yuan & Oo Than
The temporary seismic array of MySCOLAR in northern Myanmar consists of 30 broadband stations. The overall scientific goals are to understand the transition from continental collision to oceanic subduction, to quantify the partitioning of deformation in the accretionary prism, in the Burma Plate and along the strike-slip Sagaing fault system and to image the subducting Indian Plate beneath Myanmar and southwest China. The seismological analysis methods applied to this dataset will include location of local...

The GEYER seismic network

Christian Haberland, Trond Ryber & Moritz Kirsch
A network of 400 continuously running, digital, short-period seismic stations was deployed for a time period of approximately 2 weeks in an area of ~1 x 1.7 km in the Geyer region (Saxony, Germany). The network is part of a feasibility study to check whether and to which extent passive seismic methods, i.e. ambient noise techniques with a large number of stations (LARGE-N) can be used in a mineral exploration context. The project is attached...

Seismological profile across Longmenshan Fault - LONGMEN-P (2018-2020)

Changqing Yu & James Mechie
The main aim of this project is to investigate the crustal and mantle structure beneath the Longmenshan fault zone in China, based on a very dense passive seismology profile. The Longmenshan fault zone hosted the Wenchuan earthquake of May 2008 with a magnitude (Mw) of 7.9 and the Lushan earthquake of June 2013 with a magnitude (Mw) of 6.6. It is planned to mainly use the receiver-function method, to investigate the crustal and mantle structure...

The Irpinia seismic Array

Dino Bindi, Fabrice Cotton, Matteo Picozzi & Aldo Zollo
Irpinia seismic Array is part of the DEnse mulTi-paramEtriC observations and 4D high resoluTion imaging (DETECT) project focused on the acquisition of a unique multiparametric dataset and fosters collaboration among various institutions. The University of Naples Federico II (UniNa) and the German Research Centre for Geosciences (GFZ) are leading this effort carried out in collaboration with various local institutions and supported by the local municipalities. The DETECT project aims at exploiting very dense seismic networks...

DARE: Dense ARray for seismic site effect Estimation

Marco Pilz, Fabrice Cotton, Matthias Ohrnberger & Berenice Froment
The project DARE proposes an integrated study of seismic site effects on the deep and elongated Messinian Rhône Canyon (French Rhône Valley). Lithological information from boreholes reaching the bedrock and preliminary geophysical campaigns indicate that the canyon can reach locally >500 m and may be deeply incised. The strong material contrast between the sedimentary filling and the substratum, as well as its expected confined geometry make this canyon a good candidate for generating various kinds...

The COBO/CV-PLUME temporary seismic network

Michael Weber, Graça Silveira & Albrecht Schulze
There is a growing debate on the conventional plume model and no consensus about their deep origin. Davaille et al. (2005) showed, using fluid mechanics experiments, the existence of different class of plumes, depending on mantle thermo-chemical properties. Cape Verde is located in the interior of a slow-moving oceanic plate, away from the Mid-Atlantic Ridge, and is associated with one of the world’s largest swell. Some swells are believed to be caused by mantle plumes...

1 week seismological huddle test using 5 rotational sensors and 3 seismometers in August 2019

Eva P.S. Eibl, Stefanie Donner, Felix Bernauer, Gizem Izgi, Daniel Vollmer, Matthias Ohrnberger, Klaus Stammler, Mathias Hoffmann, Joachim Wassermann & Heiner Igel
We provide seismological data from a huddle test in Fürstenfeldbruck in August 2019 that was realized by University of Potsdam (PI: Eva Eibl) in collaboration with BGR (PI: Stefanie Donner) and LMU (PI: Felix Bernauer). 5 rotational sensors (blueSeis-3A) and 3 seismometers (Trillium Horizon 120s Nanometrics) were installed on a decoupled basement in a building of the Geophysical Observatory Fürstenfeldbruck. The seismometers were isolated with black foam rubber and white cotton. We recorded passive seismological...

GFZ contribution to the COSEISMIQ seismic network

Torsten Dahm, Simone Cesca, Sebastian Heimann, Stefan Mikulla & Claus Milkereit
In the frame of the EU-project COSEISMIQ (COntrol SEISmicity and Manage Induced earthQuakes) natural and induced seismic events were monitored in Iceland. A temporary seismic network has been deployed in the Hengill geothermal region in Iceland, where the two largest geothermal power plants of the country are currently in operation. The GFZ contribution was the installation and operation of a small-scale seismic array in 2019-2021 in the vicinity of the broadband station MEI05 (ETH), in...

Anillo

Frederik Tilmann, Ben Heit, Marcos Moreno & Diego González-Vidal
The Anillo is a dense temporary seismic and geodetic network extending approximately 200 km along the strike of the subduction zone in North Chile in order to investigate how earthquakes and aseismic slip scale over a broader spectrum of source sizes, to understand the complex relationships between seismic and aseismic deformation, and to identify possible structural controls. This experiment is embedded into a larger scale experimental effort carried out by institutions in Germany and Chile....

Dataset of the 3P seismic network at the Theistareykir geothermal area, Iceland, 2017-2021

Kemal Erbaş, Tania Toledo, David Naranjo, Malte Metz, Felix Rietz, Florian Forster & Philippe Jousset
Continuous passive seismic monitoring is carried out between September 2017 and December 2021 around the Theistareykir geothermal area located at the intersection between the active Northern Rift Zone and the active Tjörnes Fracture Zone in NE Iceland. This experiment, in addition to an extensive gravimetric monitoring survey, was conducted in the framework of the MicroGraviMoTiS project for a better understanding of the structures and behavior of the local geothermal system under exploitation and for further...
