Low-Frequency Seismicity at Villarrica Volcano: Source Location and Seismic Velocities
(Journal of Geophysical Research: Solid Earth, 2019)Villarrica Volcano (Chile) is one of the most active volcanoes in South America. Its low-frequency (≤5 Hz) seismicity consists of a continuous tremor, overlain by impulsive transient events of higher amplitude in 60-s ... -
Low-temperature thermochronology - methodological studies and application in collisional orogens$nElektronische Ressource
(Univ. Freiberg, 2008)Die Spaltspuren-Datierung als wesentliche Methode aus dem Bereich der Niedrigtemperatur-Thermochronologie basiert auf der Zählung und Messung geätzter Spuren unter dem Mikroskop. Für eine akkurate Altersbestimmung ist daher ... -
Lösung der Grenzflächenproblematik bei der gemeinsamen Inversion geoelektrischer und seismischer Daten von oberflächennahen, porösen Schichten
(Univ. Bochum, 2001)Bisherige Ansätze Daten aus Seismik und Geoelektrik durch einen Joint Inversionsalgorithmus zu interpretieren schlagen oftmals fehl, da sowohl die Tiefen und Formen der Grenzflächen als auch die Grenzflächenanzahl für die ... -
Lumineszenzdatierung glazifluvialer Sedimente im nördlichen Alpenvorland
(Univ. Köln, 2008)Das nördliche Alpenvorland gilt als klassische Region der Quartärforschung. Hier wurde das System der quartären Eiszeiten anhand der Terrassenstratigraphie entwickelt (PENCK & BRÜCKNER 1901/1909). Die drei letzten Eiszeiten ... -
L‐Band Synthetic Aperture Radar Observation of Ionospheric Density Irregularities at Equatorial Plasma Depletion Region
(Geophysical Research Letters, 2021-08-23)Plasma density irregularities in the equatorial ionosphere are thought to cause the distortions of L‐band Synthetic Aperture Radar (SAR) images, which have been observed in recent years, but the origin of the image distortion ... -
Machine Learning‐Based Prediction of Spatiotemporal Uncertainties in Global Wind Velocity Reanalyses
(Journal of Advances in Modeling Earth Systems, 2020-05-13)The characterization of uncertainties in geophysical quantities is an important task with widespread applications for time series prediction, numerical modeling, and data assimilation. In this context, machine learning is ... -
Macroporosity and Grain Density of Rubble Pile Asteroid (162173) Ryugu
(Journal of Geophysical Research: Planets, 2020-12-04)Rubble pile asteroids such as (162173) Ryugu have large bulk porosities, which are believed to result from void spaces in between the constituent boulders (macroporosity) as well as void spaces within the boulders themselves ... -
Magmatic Activity and Dynamics of Melt Supply of Volcanic Centers of Ultraslow Spreading Ridges: Hints From Local Earthquake Tomography at the Knipovich Ridge
(Geochemistry, Geophysics, Geosystems, 2022-10-07)Along ultraslow spreading ridges melt is distributed unequally, but melt focusing guides melt away from amagmatic segments toward volcanic centers. An interplay of tectonism and magmatism is thought to control melt ascent, ... -
Magmatic and Sedimentary Structure beneath the Klyuchevskoy Volcanic Group, Kamchatka, From Ambient Noise Tomography
(Journal of Geophysical Research: Solid Earth, 2020-03-14)The Klyuchevskoy Volcanic Group is a cluster of the world's most active subduction volcanoes, situated on the Kamchatka Peninsula, Russia. The volcanoes lie in an unusual off‐arc position within the Central Kamchatka ... -
Magnetic coupling of the solar photosphere and chromosphere
(Univ. Freiburg (Breisgau), 2008)The solar surface outside sunspots and active regions, i.e., the quiet Sun, shows the ubiquitous pattern of granulation in the photosphere. The quiet solar photosphere harbors small-scale magnetic structures inside and ... -
Magnetic Fields and Plasma Motions in a Hybrid Martian Magnetosphere
(Journal of Geophysical Research: Space Physics, 2023-01-04)The Martian magnetosphere contains elements of induced and intrinsic origin. To display them one must use different coordinate systems. Although the solar‐electric coordinate system (Mars Solar Electric [MSE]) adequately ... -
