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)
(Journal of Seismology, 2020-12-16)Since the mid-1990s, the local seismic network of the University of Cologne has produced digital seismograms. The data all underwent a daily routine processing. For this study, we re-processed data of almost a quarter ... -
Seismische Methoden in der Lagerstättenforschung
(Urania-Magazin, 1953)Der Beitrag gibt eine Einführung zur Entwicklungsgeschichte der Explorationsseismik. -
Seismisches Monitoring an lehmigen Modelldeichen
(Univ. Freiberg (Sachsen), 2008)An lehmigen Modelldeichen mit beliebig variierbaren Hochwasserbelastungen wurde ein Monitoring mit einer hochauflösenden Seismik durchgeführt. Mit den in dieser Arbeit vorgestellten Messungen des seismischen Messsystems ... -
Seismological and Geophysical Signatures of the Deep Crustal Magma Systems of the Cenozoic Volcanic Fields Beneath the Eifel, Germany
(Geochemistry, Geophysics, Geosystems, 2020)The Quaternary volcanic fields of the Eifel (Rhineland-Palatinate, Germany) had their last eruptions less than 13,000 years ago. Recently, deep low-frequency (DLF) earthquakes were detected beneath one of the volcanic ... -
Seismotectonics of the Blanco Transform Fault System, Northeast Pacific: Evidence for an Immature Plate Boundary
(Journal of Geophysical Research: Solid Earth, 2023-03-09)At the Blanco transform fault system (BTFS) off Oregon, 138 local earthquakes and 84 double‐couple focal mechanisms from ocean‐bottom‐seismometer recordings jointly discussed with bathymetric features reveal a highly ... -
Self-tuning robust adjustment within multivariate regression time series models with vector-autoregressive random errors
(Journal of Geodesy, 2020-05-10)The iteratively reweighted least-squares approach to self-tuning robust adjustment of parameters in linear regression models with autoregressive (AR) and t-distributed random errors, previously established in Kargoll et ... -
Self‐Validating Deep Learning for Recovering Terrestrial Water Storage From Gravity and Altimetry Measurements
(Geophysical Research Letters, 2020-08-28)Quantifying and monitoring terrestrial water storage (TWS) is an essential task for understanding the Earth's hydrosphere cycle, its susceptibility to climate change, and concurrent impacts for ecosystems, agriculture, and ... -
Sensitivity and depth of investigation from Monte Carlo ensemble statistics
(Geophysical Prospecting, 2021-01-26)For many geophysical measurements, such as direct current or electromagnetic induction methods, information fades away with depth. This has to be taken into account when interpreting models estimated from such measurements. ... -
Sensitivity of Convection Permitting Simulations to Lateral Boundary Conditions in Idealized Experiments
(Journal of Advances in Modeling Earth Systems, 2021-12-23)Limited‐area convection‐permitting climate models (CPMs) with horizontal grid‐spacing less than 4 km and not relying on deep convection parameterisations (CPs) are being used more and more frequently. CPMs represent ... -
Sensitivity of Sea Ice Growth to Snow Properties in Opposing Regions of the Weddell Sea in Late Summer
(Geophysical Research Letters, 2022-09-30)The sensitivity of sea ice to the contrasting seasonal and perennial snow properties in the southeastern and northwestern Weddell Sea is not yet considered in sea ice model and satellite remote sensing applications. However, ... -
Sensitivity study of the planetary boundary layer and microphysical schemes to the initialization of convection over the Arabian Peninsula
(Quarterly Journal of the Royal Meteorological Society, 2019)In this study, we present a five-member Weather Research and Forecasting (WRF) physics ensemble over the Arabian Peninsula on the convection-permitting (CP) scale and investigate the ability to simulate convection and ... -
Sensitivity to changes in the surface‐layer turbulence parameterization for stable conditions in winter: A case study with a regional climate model over the Arctic
(Atmospheric Science Letters, 2021-08-24)The modeling of the atmospheric boundary layer over sea ice is still challenging because of the complex interaction between clouds, radiation and turbulence over the often inhomogeneous sea ice cover. There is still much ... -
