Formation processes of the 1909 Tarumai and the 1944 Usu lava domesin Hokkaido,Japan
lava domes Tarumai volcano Usu volcano squeeze of magma growth rate of domes Hagen-Poiseuille's Law
2015/9/11
The formation of the two particular lava domes in Hokkaido, Japan is described and interpreted mainly from geophysical viewpoints. The 1909 eruption of Tarumai volcano was not violent but produced a l...
Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes
noble gases solubility degassing silicate melts
2015/9/10
Noble gas solubility in silicate melts and glasses has gained a crucial role in Earth Sciences investigations and
in the studies of non-crystalline materials on a micro to a macro-scale. Due to their...
Chronostratigraphic study of the Grottaperfetta alluvial valley in the city of Rome (Italy): investigating possible interaction between sedimentary and tectonic processes
Holocene stratigraphy recent tectonics Tiber valley
2015/9/1
We carried out geomorphologic and geological investigations in a south-eastern tributary valley of the Tiber River in Rome, the Grottaperfetta valley, aimed to reconstruct its buried geometry. Since r...
Source Processes for the Probabilistic Assessment of Tsunami Hazards
Tsunami Hazards Source Processes
2015/7/17
The importance of tsunami hazard assessment has increased in recent years as a result of catastrophic consequences from events such as the 2004 Indian Ocean and 2011 Japan tsunamis. In particular, pro...
A new WRF-Chem treatment for studying regional-scale impacts of cloud processes on aerosol and trace gases in parameterized cumuli
regional-scale impacts new WRF-Chem treatment
2015/3/5
A new treatment of cloud effects on aerosol and
trace gases within parameterized shallow and deep convection, and aerosol effects on cloud droplet number, has been
implemented in the Weather Researc...

Transport processes at quartz–water interfaces: constraints from hydrothermal grooving experiments
Hydrothermal annealing experiment quartzite fluid pressure the topological structure
2015/1/6
We performed hydrothermal annealing experiments on quartzite samples at temperatures of 392 to 568 °C and fluid pressures of 63 to 399 MPa for up to 120 h, during which hydrothermal grooves developed ...
Focal mechanisms in the southern Aegean from temporary seismic networks – implications for the regional stress field and ongoing deformation processes
Focal mechanisms the southern Aegean temporary seismic networks the regional stress field ongoing deformation processes
2015/1/6
The lateral variation of the stress field in the southern Aegean plate and the subducting Hellenic slab is determined from recordings of seismicity obtained with the CYCNET and EGELADOS networks in th...
Morphology and surface features of olivine in kimberlite: implications for ascent processes
Morphology surface features olivine kimberlite ascent processes
2015/1/6
Most kimberlite rocks contain large proportions of ellipsoidal-shaped xenocrystic olivine grains that are derived mainly from disaggregation of peridotite. Here, we describe the shapes, sizes and surf...
Experimental deformation and recrystallization of olivine – processes and timescales of damage healing during postseismic relaxation at mantle depths
Experimental deformation recrystallization of olivine
2015/1/5
. Experiments comprising sequences of deformation (at 300 or 600◦C) and annealing at varying temperature (700 to 1100◦C), time (up to 144 h) and stress (up
to 1.5 GPa) were carried out in...
Observations of surface radiation and stratospheric processes at Thule Air Base, Greenland, during the IPY
Polar atmosphere NDACC Radiative budget Stratospheric ozone

Ground-based measurements of atmospheric parameters have been carried out for more than 20 years at the Network for the Detection of Atmospheric Composition Change (NDACC) station at Thule Air Base (7...
Evidence of upper-mantle processes related to continental rifting versus oceanic crust in the Gulf of California
Mantle processes Phase transitions North America
2014/4/10
Receiver functions from teleseismic events, recorded by stations around the Gulf of California, are used to map the upper-mantle seismic discontinuities. We observe a mean transition zone thickness co...
