Patterns permafrost soils climate change models
2020/6/12
The Arctic covers about 20% of the planet. But almost everything hydrologists know about the carbon-rich soils blanketing its permafrost comes from very few measurements taken just feet from Alaska's ...
Magnetic anomaly patterns over crustal blocks of the King Edward VII Peninsula, Marie Byrd Land, West Antarctica
Edward VII Peninsula Aeromagnetic anomalies tectonic block west antarctic rift system Marie Byrd Land antartica
2015/9/28
Within the framework of the GITARA II project an aeromagnetic survey was performed during the GANOVEXVII expedition (1992/1993) over the King Edward VII Peninsula in northwestern Marie Byrd Land (West...
The analysis of the Standardized Precipitation Index in the Mediterranean area:large-scale patterns
Climate variability drought monitoring
2015/9/28
Problems related to the identification and monitoring of drought are investigated. In particular, drought conditions in Italy are examined using the Standardized Precipitation Index (SPI) on different...
The analysis of the Standardized Precipitation Index in the Mediterranean area:regional patterns
Rainfall observatory drought climate variability
2015/9/28
In the present paper we propose a method to assess regional drought by using rain-gauge observations. In particular, we analyse the rainfall on the Marche region. We diagnose drought by means of the S...
Mediterranean precipitation and its relationship with sea level pressure patterns
Mediterranean precipitation principal component canonical correlation trajectory
2015/9/15
The relationship between Mediterranean precipitation and North Atlantic and European sea level pressure fields has been studied using statistical techniques to investigate the variability within the d...
Earthquake fault-plane solutions and patterns of seismicity within the Umbria Region,Italy
fault-plane solution seismicity seismotectonic Italy
2015/9/8
In this paper we present a review of the seismotectonic features (an analysis of earthquake focal mechanisms and the distribution of seismicity) of the Northern Apennines, Umbria Region (Italy) in the...
Historical earthquakes and damage patterns in Potenza (Basilicata, Southern Italy)
Basilicata Potenza historical earthquake damage pattern seismic microzonation
2015/9/2
This paper analyzes three historical seismic damage patterns in Potenza, the main town of the Basilicata Region,
in Southern Italy. We refer to the 1826, 1857 and 1930 earthquakes, which hit the town...
Shear-wave velocity structure at Mt. Etna from inversion of Rayleigh-wave dispersion patterns (2 s < T < 20 s)
Mount Etna Rayleigh-wave dispersion S-wave velocity modeL Non-linear inversion Triangle method
2015/8/28
In the present study, we investigated the dispersion characteristics of medium-to-long period Rayleigh waves (2 s < T < 20 s) using both single-station techniques (multiple-filter analysis, and phase-...
Strain patterns along the Kaparelli–Asopos rift (central Greece) from campaign GPS data
GPS Strain Kaparelli Central Greece
2015/8/14
We present results from four GPS campaigns in the broader Kaparelli–Asopos area in central Greece. This area is undergoing extension as demonstrated by seismological, geodetic and geological data. The...
Eruption patterns of parasitic volcanoes
Parasitic vents Parasitic eruptions Shear fracture model Twin parasitic vents Various patterns of parasitic eruptions
2015/8/14
Eruption patterns of parasitic volcanoes are discussed in order to study their correlation to the activities of their parental polygenetic volcanoes. The distribution density of parasitic vents on pol...
Finite lattice distortion patterns in plastically deformed zircon grains
Limit deformation mode the grains high temperature and natural shear zone the Alps MaYan
2015/1/6
This study examines finite deformation patterns of zircon grains from high-temperature natural shear zones. Various zircon-bearing rocks were collected in the Western Tauern Window, eastern Alps, wher...
Towards inferring earthquake patterns from geodetic observations of interseismic coupling
earthquake patterns geodetic observations interseismic coupling
2010/5/8
Ultimately, seismotectonic studies seek to provide ways of assessing the timing, magnitude and spatial extent of future earthquakes. Ample observations document the spatial variability in interseismic...
Dynamical segmentation and rupture patterns in a toy slider-block model for earthquakes
Dynamical segmentation rupture patterns toy slider-block model for earthquakes
2009/11/16
Lattice models for earthquakes have been shown to capture some of the dynamical properties possessed by natural fault systems. These properties include: 1) a scaling (power low) region in the curve re...
The work considers three-dimensional crescent-shaped patterns often seen on water surface in natural basins and observed in wave tank experiments. The most common of these 'horse-shoe-like' patterns a...

2009/11/12
The instability patterns in the flow between counter-rotating disks (radius to height ratio R/h from 3.8 to 20.9) are investigated experimentally by means of visualization and Particle Image Velocimet...
