The role of instrumental versus macroseismic locations for earthquakes of the last century: a discussion based on the seismicity of the North-Western Apennines (Italy)
historical seismicity velocity propagation model Joint Hypocentral Determination
2015/9/10
Many seismological observatories began to record and store seismic events in the early years of the twentieth century,
contributing to the compilation of very valued databases of both phase pickings ...
Polymerisation, basicity, oxidation state and their role in ionic modelling of silicate melts
polymerisation basicity oxidationstate water speciation Temkin model
2015/9/10
In order to describe and quantify the reactivity of silicate melts, the ionic notation provided by the Temkin formalism
has been historically accepted, giving rise to the study of melt chemical equil...
Glacio and hydro-isostasy in the Mediterranean Sea:Clarks zones and role of remote ice sheets
sea-level variations glacial isostasy Mediterranean Sea
2015/9/2
Solving the sea-level equation for a spherically symmetric Earth we study the relative sea-level curves in the Mediterranean Sea in terms of Clarks zones and we explore their sensitivity to the time-h...
Geoethics and philosophy of Earth sciences: the role of geophysical factors in human evolution
Philosophy of Earth Sciences Scientific Prediction Nature Probability
2015/8/26
This article explores the role of philosophy of the Earth sciences in the foundation of the principles of ‘geoethics’. In particular, the focus is on two different examples of philosophical analysis i...
The role of radiation damping in the modeling of repeated earthquake events
Seismic cycle Earthquake recurrence Radiation damping Spring-slider model Fault rheology Computational seismology
2015/8/18
We have investigated the role of the radiation damping term (RDT) on repeated earthquake ruptures by modeling the faulting process through a single one-dimensional analog fault system governed by diff...
Background electromagnetic noise characterization: the role of external and internal Earth sources
Radio noise characterization Ionosphere-magnetosphere Background EM noise Crustal/lithospheric EM sources
2015/8/14
The Earth is surrounded by the ionosphere and magnetosphere that can roughly be seen schematically as two concentric shells. These two composed and inhomogeneous structured shells around the Earth sel...
Orographic role in anomalous VHF propagation on the background of impending earthquakes (EQ)
Orography EQ and VHF anomalous propagation Earthquake RRI Terrain features
2015/8/14
The role of orographic factors in modifying atmospheric dynamics on the background of an impending earthquake (EQ) that might lead to propagation of a signal beyond the Line Of Sight (LOS) is examined...
Velocity structure and the role of fluids in the West Bohemia Seismic Zone
Double difference fault three-dimensional structure seismic belt regional earthquakes earthquake focal mechanism
2015/1/6
In this study, we apply the double-difference tomography to investigate the detailed 3-D structure within and around the Novy Kostel Seismic Zone, an area in the Czech Republic known for frequent occu...
The role of karst in engineering and environmental geosciences

2014/12/31
Karst is a unique landform developed by soluble rock. It usually relates to the groundwater drainage system, and provides important water resources. Current researches indicate that karst is closely r...
Geomagnetic polar observatories: the role of Concordia station at Dome C,Antarctica
Geomagnetic observatory GNSS Azimuth Mark Determination Dome C Concordia Antarctica
2015/8/18
A geomagnetic observatory is a permanent facility where magnetic declination and inclination are recorded in conjunction with the temporal evolution of the magnetic field components. Polar regions are...
Generation of talc in the mantle wedge and its role in subduction dynamics in central Mexico
Subduction talc serpentine receiver function mantle wedge P-to-S velocity ratio
2014/4/10
Geophysical evidence shows the presence of low-seismic velocity material at the surface of slabs in subduction zones. In the central Mexican subduction zone this appears as a thin (～4 km) low-velocity...
The role of velocity-neutral creep on the modulation of tectonic tremor activity by periodic loading
velocity-neutral creep on the modulation tectonic tremor activity periodic loading
2014/4/15
Slow slip events and associated non-volcanic tremors are sensitive to oscillatory stress perturbations, such as those induced by tides or seismic surface waves. Slow slip events and tremors are though...
Petrogenesis of Early Cretaceous silicic volcanism in SE Uruguay: The role of mantle and crustal sources
