Combining historical and process perspectives to infer ranges of geomorphic variability and inform river restoration in a wandering gravel-bed river
submitted by jabylyn 1 day ago
Restoration approaches such as dam removal and channel reconstruction have moved beyond the realm of small streams and are being applied to larger rivers. This development has substantial economic ...
 


On the application of Particle Swarm Optimization strategies on Scholte-wave inversion
submitted by drrlawry 1 day ago
We investigate different aspects concerning the application of swarm intelligence optimization to the inversion of Scholte-wave phase-slowness frequency (p–f) spectra with respect to shear wave v...
 
High-resolution surface wave tomography beneath the Aegean-Anatolia region: constraints on upper-mantle structure
submitted by RoberZach 1 day ago
This study provides new constraints on the upper-mantle structure from western Greece to central Anatolia using seismic data of permanent broad-band networks recently installed in Greece and Turkey...
 
Imaging mantle plumes with instantaneous phase measurements of diffracted waves
submitted by oshliik16 1 day ago
In a synthetic tomographic experiment, we succeeded to recover an idealized narrow mantle plume reaching deep into the lower mantle by using a misfit based on the instantaneous phase difference. A ...
 


Seismic anisotropy and heterogeneity in the Alaska subduction zone
submitted by ovemohlir 1 day ago
We determined P- and S-wave tomography and P-wave anisotropic structure of the Alaska subduction zone using 259 283 P- and 73 817 S-wave arrival times from 7268 local shallow and intermediate-depth...
 
Timing of Xunhua and Guide basin development and growth of the northeastern Tibetan Plateau, China
submitted by KonnoFel 1 day ago
The Xunhua, Guide and Tongren intermontane basin system in the NE Tibetan Plateau, situated near the Xining basin to the N and the Linxia basin to the E, is bounded by thrust fault-controlled range...
 
Miocene sedimentation, volcanism and deformation in the Eastern Cordillera (24°30′ S, NW Argentina): tracking the evolution of the foreland basin of the Central Andes
submitted by rom 1 day ago
Understanding the relationships between sedimentation, tectonics and magmatism is crucial to defining the evolution of orogens and convergent plate boundaries. Here, we consider the lithostratigrap...
 
Late Cenozoic tectono-stratigraphic sequences of the Crotone Basin: insights on the geodynamic history of the Calabrian arc and Tyrrhenian Sea
submitted by BraAeda 1 day ago
The Crotone Basin was generated in the late Cenozoic as a forearc basin of the Ionian arc-trench system. New data are gained through detailed field mapping, high-resolution stratigraphic analysis o...
 
Soft and Hard Clustering Methods for Delineation of Hydrological Homogeneous Regions in the Southern Strip of the Caspian Sea Watershed
submitted by lalelu 2 days ago
Regionalization is a fundamental task for transferring hydrological information from gaged to ungaged catchments. This study employs several soft and hard clustering approaches for regionalization ...
 
An Improved Analytic Signal Technique for the Depth and Structural Index form 2D Magnetic Anomaly Data
submitted by DarTerre 2 days ago
This paper presents a new inversion method for the interpretation of 2D magnetic anomaly data, which uses the combination of the analytic signal and its total gradient to estimate the depth and the...
 
Solar-Terrestrial Signal Record in Tree Ring Width Time Series from Brazil
submitted by gargtosh 2 days ago
This work investigates the behavior of the sunspot number and Southern Oscillation Index (SOI) signal recorded in the tree ring time series for three different locations in Brazil: Humaitá in Amaz...
 
Coastal Sedimentation Associated with the Tohoku Tsunami of 11 March 2011 in South Kuril Islands, NW Pacific Ocean
submitted by mofotlolmkhir 2 days ago
Sediment deposited by the Tohoku tsunami of March 11, 2011 in the Southern Kurils (Kunashir, Shikotan, Zeleniy, Yuri, Tanfiliev islands) was radically different from sedimentation during local stro...
 
Multifractality in Seismicity Spatial Distributions: Significance and Possible Precursory Applications as Found for Two Cases in Different Tectonic Environments
submitted by snawyjion 2 days ago
We explore fractal properties of two observed seismicity distributions prior to the 2003 Mw 7.4 Colima, Mexico and 1992 Mw 7.3 Landers, USA earthquakes, together with several mathematical fractal d...
 
A Revised Evaluation of Tsunami Hazards along the Chinese Coast in View of the Tohoku-Oki Earthquake
submitted by sason227 2 days ago
Japan’s 2011 Tohoku-Oki earthquake and the accompanying tsunami have reminded us of the potential tsunami hazards from the Manila and Ryukyu trenches to the South China and East China Seas. Stati...
 
Location Performance and Detection Magnitude Threshold of the Romanian National Seismic Network
submitted by ortwretis 2 days ago
Romania is an earthquake prone area with a few destructive earthquakes per century. The National Institute for Earth Physics carries out the seismic survey of Romania through the Romanian National ...
