Volcanic ash plumes are formed during explosive volcanic eruptions. After advection over several thousands of kilometers, volcanic ash particles are highly fragmented, dispersed and aged with micron- ...
Volcanic Ash Cloud Observation using Ground-based Ka-band Radar and Near-Infrared Lidar Ceilometer during the Eyjafjallajökull eruption
Volcanic eruptions radar lidar
2015/8/18
Active remote sensing techniques can probe volcanic ash plumes, but their sensitivity at a given distance depends upon the sensor transmitted power, wavelength and polarization capability. Building on...
About the Mechanism of Geyser Eruption
Mechanism of Geyser Eruption Geophysics Fluid Dynamics
2012/4/20
Essentially new physical mechanism of geyser eruption based on instability in "water-vapor" system is proposed. Necessary and sufficient conditions of eruptions are received. For group of Kamchatka ge...
Multi-Wavelength Observations of a Flux Rope Failed in the Eruption and Associated M-Class Flare from NOAA AR 11045
coronal loops magnetic eld ux rope magnetic reconnection
2011/9/27
We present the multi-wavelength observations of a flux rope that was trying to erupt from NOAA AR 11045 and the associated M-class solar flare on 12 February 2010 using space and ground based observat...
The impact of the Kasatochi eruption on the Moon's illumination during the August 2008 lunar eclipse
Kasatochi Moon's illumination lunar eclipse
2011/9/14
The Moon抯 changeable aspect during a lunar eclipse is largely attributableto variations in the refracted unscattered sunlight absorbed by the terres trial atmosphere that occur as the satellite crosse...
A simple semi-empirical approach to model thickness of ash-deposits for different eruption scenarios
semi-empirical approach model thickness ash-deposits different eruption scenarios
2011/1/19
The impact of ash-fall on people, buildings, crops, water resources, and infrastructure depends on several factors such as the thickness of the deposits, grain size distribution and others. Preparedne...
Photospheric flux cancellation and associated flux rope formation and eruption
Sun photosphere – Sun coronal mass ejections – Sun magnetic fields
2010/11/11
Aims. We study an evolving bipolar active region that exhibits flux cancellation at the internal polarity inversion line, the formation of a soft X-ray sigmoid along the inversion line and a coronal m...
Source Mechanism of Long Period events recorded by a high density seismic network during the 2008 eruption on Mt Etna
Source Mechanism high density seismic network the 2008 eruption on Mt Etna
2010/11/16
129 Long Period (LP) events, divided into two families of similar events, were recorded by the 50 stations deployed on Mount Etna in the second half of June 2008. During this period lava was flowing ...

Statistical eruption forecast for the Chilean Southern Volcanic Zone: typical probabilities of volcanic eruptions as baseline for possibly enhanced activity following the large 2010 Concepción earthquake
Chilean Southern Volcanic Zone typical probabilities volcanic eruptions as baseline possibly enhanced activity
2010/10/21
A probabilistic eruption forecast is provided for ten volcanoes of the Chilean Southern Volcanic Zone (SVZ). Since 70% of the Chilean population lives in this area, the estimation of future eruption l...
