Segment‐Scale Seismicity of the Ultraslow Spreading Knipovich Ridge
(Geochemistry, Geophysics, Geosystems, 2021-02-23)Ultraslow spreading ridges form the slowest divergent plate boundaries and exhibit distinct spreading processes in volcanically active magmatic sections and intervening amagmatic sections. Local seismicity studies of ... -
Seiscloud, a tool for density-based seismicity clustering and visualization
(Journal of Seismology, 2020-05-07)Clustering algorithms can be applied to seismic catalogs to automatically classify earthquakes upon the similarity of their attributes, in order to extract information on seismicity processes and faulting patterns out of ... -
Seismic and Aseismic Preparatory Processes Before Large Stick–Slip Failure
(Pure and Applied Geophysics, 2020-10-26)Natural earthquakes often have very few observable foreshocks which significantly complicates tracking potential preparatory processes. To better characterize expected preparatory processes before failures, we study ... -
Seismic and hydroacoustic studies of surficial sediment tectonics along the northern Red Sea Rift and the Dead Sea Transform fault
(Univ. Hamburg, 2005)This work presents multichannel seismic and hydroacoustic data of four survey areas along the Red Sea Rift and the Dead Sea Transform Fault. Sedimentary Basins that developed due to the rifting of the Red Sea and the ... -
Seismic and Tsunamigenic Characteristics of a Multimodal Rupture of Rapid and Slow Stages: The Example of the Complex 12 August 2021 South Sandwich Earthquake
(Journal of Geophysical Research: Solid Earth, 2022-11-07)On 12 August 2021, a >220 s lasting complex earthquake with Mw > 8.2 hit the South Sandwich Trench. Due to its remote location and short interevent times, reported earthquake parameters varied significantly ... -
Seismic constraints on rock damaging related to a failing mountain peak: the Hochvogel, Allgäu
(Earth Surface Processes and Landforms, 2020-11-29)Large rock slope failures play a pivotal role in long‐term landscape evolution and are a major concern in land use planning and hazard aspects. While the failure phase and the time immediately prior to failure are increasingly ... -
Seismic Full‐Waveform Inversion of the Crust‐Mantle Structure Beneath China and Adjacent Regions
(Journal of Geophysical Research: Solid Earth, 2022-09-19)We present the first‐generation full‐waveform tomographic model (SinoScope 1.0) for the crust‐mantle structure beneath China and adjacent regions. The three‐component seismograms from 410 earthquakes recorded at 2,427 ... -
Seismic imaging in complex media with the common reflection surface stack
(Univ. Hamburg, 2009)Reflection seismic is one of the most commonly used geophysical method for the oil and gas exploration. In this thesis I show the application of the Common Reflection Surface (CRS) stack technique to improve the quality ... -

Seismic P Wave Velocity Model From 3-D Surface and Borehole Seismic Data at the Alpine Fault DFDP-2 Drill Site (Whataroa, New Zealand)
(Journal of Geophysical Research: Solid Earth, 2020)The New Zealand Alpine Fault is a major plate boundary that is expected to be close to rupture, allowing a unique study of fault properties prior to a future earthquake. Here we present 3-D seismic data from the DFDP-2 ... -
Seismic Velocity Recovery in the Subsurface: Transient Damage and Groundwater Drainage Following the 2015 Gorkha Earthquake, Nepal
(Journal of Geophysical Research: Solid Earth, 2022-02-01)Shallow earthquakes frequently disturb the hydrological and mechanical state of the subsurface, with consequences for hazard and water management. Transient post‐seismic hydrological behavior has been widely reported, ... -
Seismic Velocity Variations in a 3D Martian Mantle: Implications for the InSight Measurements
(Journal of Geophysical Research: Planets, 2021-06-17)We use a large data set of 3D thermal evolution models to predict the distribution of present‐day seismic velocities in the Martian interior. Our models show a difference between maximum and minimum S wave velocity of up ... -
Seismicity in the Northern Rhine Area (1995–2018)
