10 Years Indonesian Tsunami Early Warning System. Experiences, Lessons Learned and Outlook

J. Lauterjung & Horst Letz
The German-Indonesian Tsunami Early Warning System (GITEWS) has been established after the devastating Tsunami in the Indian Ocean on December 26, 2004. It became an integral part of the Indonesian Tsunami Early Warning System (InaTEWS) providing sensor networks and core computational components. GITEWS follows an “end-to-end” approach to cover the complete warning chain from rapid hazard detection over decision support to capacity development of communities at risk and the implementation of disaster reduction measures.

GITW-SSP-FMT-GFZ-003: Remotely Operated Multi-Parameter Stations; System Software Output Format Specification; METEOD

Tilo Schöne, Cornelia Zech & Julia Illigner
In recent years, an extensive network of Remotely Operated Multi-Parameter Stations (ROMPS) has been installed in different countries and climatic zones. The stations were developed by GFZ for various applications and set up together with the corresponding partners in the particular regions. In this sense, the general station with its core functionality (querying and storing of sensor data, transmission of data to a central storage unit, providing sufficient energy for the station) is referred as...

Wie lassen sich Vulkane unterscheiden?

Oliver Jorzik, Jana Kandarr, Pia Klinghammer & Dierk Spreen
Für die Erforschung und die Bewertung des Gefährdungspotenzials von Vulkanen muss man ihre Eigenschaften kennen. Wissenschaftliche Kriterien helfen, Vulkane voneinander zu unterscheiden und differenziert zu beschreiben.

Wo finden Reisende aktuelle Informationen zu Vulkanaktivitäten?

Oliver Jorzik, Jana Kandarr, Pia Klinghammer & Dierk Spreen
Die nächste Reise soll in ein Land gehen, in dem es Vulkane gibt. Möglicherweise sind diese Vulkane jedoch gerade aktiv. Nicht alle Urlauber haben Vulkane als Naturgefahr im Blick, wenn sie eine Reise planen. Ob es in der Nähe des Urlaubsziels Vulkanaktivitäten gibt, sollte jeweils aktuell in Erfahrung gebracht werden. Dafür haben wir als ESKP-Redaktion eine Linkliste der lokalen Vulkanüberwachungsdienste zusammengestellt, die aktuelle Vulkan-Informationen für ausgewählte Urlaubsländer und Regionen bereitstellt.

Lassen sich vulkanische Risiken und eventuelle Katastrophen managen?

Oliver Jorzik
Bei der Beobachtung von Vulkanen und der Einschätzung von Risiken hat die Wissenschaft in den vergangenen Jahrzehnten große Fortschritte gemacht. Aber greifen diese Erkenntnisse auch, wenn es um vulkanische Großereignisse geht wie zum Beispiel Supereruptionen? Der britische Vulkanologe Clive Oppenheimer hat sich in seinem Standardwerk „Eruptions that Shook the World“ dieser Frage gewidmet.

Risikoanalysen in Zentralasien

Massimiliano Pittore, Marc Wieland, Dino Bindi, Shahid Ullah, Marco Pilz, Kevin Fleming & Stefano Parolai
The threat to human society arising from earthquakes should never be underestimated, especially in those regions of the world more exposed to this natural hazard. The complex geodynamics of Central Asia make it a natural research laboratory for the geoscience community, but also present a source of serious concern for local populations and their administrations who have already dealt with the devastating consequence of earthquakes in the past. Evaluating expected seismic risk for the exposed...

Konzepte für die Überwachung vulkanischer Seen. Interview

Egbert Jolie
Nicht nur aktive Vulkane sollten kontinuierlich überwacht werden, auch von vulkanischen Seen können Gefahren ausgehen, die ein Monitoring notwendig machen. Wichtig zur Bewertung des Gefährdungspotentials und dem daraus resultierenden Risiko ist ein interdisziplinärer Monitoring-Ansatz. Hierzu gehören beispielsweise Verfahren zur Bestimmung von chemischen Parametern, Gasemissionen, der Wasser- wie auch Seebodentemperatur oder auch der Hangstabilität von Kraterflanken. Welche Parameter letztendlich entscheidend sind, hängt von den geologischen Gegebenheiten ab. Im Interview erläutert Dr. Egbert Jolie vom Deutschen GeoForschungsZentrum,...

Retrieval of earthquake source parameters in inhomogeneous anisotropic media with application to swarm events in West Bohemia in 2000

Dirk Rößler
In der vorliegenden Arbeit werden der Einfluss seismischer Anisotropie auf wahre oder scheinbar auftretende tensile Quellanteile untersucht und Erdbebenmechanismen unter Berücksichtigung seismischer Anisotropie bestimmt. Es wird gezeigt, dass derMomententensor und die Abstrahlmuster eines Scherbruches im anisotropen Mediumdenen eines tensilen Bruches im isotropen Medium ähneln können. Umgekehrt tretenÄhnlichkeiten tensiler Beben in anisotropen Gesteinen mit Scherbrüchen in isotropenMedien auf. Damit existieren Mehrdeutigkeiten beobachteter tensiler Quellanteile. DieEffekte von Anisotropie hängen von der Orientierung des Bruches und vom Grad...

Adopting and reflecting current developments in the research data landscape, the update of the service architecture in COREF is based on a bottom-up approach that addresses the results from a stakeholder survey and a stakeholder...

Neogene seismotectonics of the south-central Chile margin : subduction-related processes over various temporal and spatial scales

Daniel Melnick
This study focuses on tectonics at the Neogene and late Quaternary time scales in the Main Cordillera and coastal forearc of the south-central Andes. For both domains I document the existence of previously unrecognized active faults and present estimates of deformation rates and fault kinematics. Furthermore these data are correlated to address fundamental mountain building processes like strain partitioning and largescale segmentation.

A long-term model for non-tidal atmospheric and oceanic mass redistributions and its implications on LAGEOS-derived solutions of Earth's oblateness

Frank Flechtner, Maik Thomas & Rolf König
The dynamic oblateness of the Earth, in terms of the J2 or C20 coefficient of theEarth´s geo-potential has been derived by analysis of LAGEOS Satellite LaserRanging (SLR) data. Although recent analyses of GRACE (Gravity Recovery andClimate Experiment) mission data of monthly C20 values since 2002 have shown hightemporal correlations with LAGEOS results, significant differences still remain. As it iscommon practice in GRACE data processing to remove a priori the short-term nontidalatmospheric and oceanic induced variations...

Global modeling of the effect of strong lateral viscosity variations on dynamic geoid and mantle flow velocities

Irina Rogozhina
This study is aimed at a development of numerical method to model the dynamic geoid and the surface plate velocities induced by global mantle flow with the effect of strong lateral viscosity variations (LVV) in conjunction with the effects of selfgravitationand mantle compressibility. I employ the technique, which comprises the combination of the spherical harmonic method, the direct Godunov method used for solving the Stokes and Poisson equations in spherical harmonics with arbitrary boundary conditions,...
