The ash-fall hazard from a Plinian eruption at Colima Volcano,Mexico
Ash-fall hazard Colima Volcano Mexico
2015/8/28
The historical eruptive activity at Colima Volcano has been characterized by Strombolian and Merapi type eruptions and Vulcanian explosions associated with dome growth, which have ended in a Plinian e...
Annex to:Volcanic Ash Cloud Observation using Ground-based Ka-band Radar and Near-Infrared Lidar Ceilometer during the Eyjafjallajökull eruption

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- ...
Improvements on Near Real Time Detection of Volcanic Ash Emissions for Emergency Monitoring with Limited Satellite Bands
Volcanic ash disperion monitoring satellite dispersion model
2015/8/18
Quantifying volcanic ash emissions syneruptively is an important task for the global aviation community. However, due to the near real time nature of volcano monitoring, many parameters important for ...
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...
Volcanic Ash and SO2 retrievals using synthetic MODIS TIR data:comparison between inversion procedures and sensitivity analysis
Volcanic Ash SO2 retrievals synthetic MODIS TIR data
2015/8/18
In this work the volcanic ash and SO2 retrievals obtained by applying three different procedures (LUT - Look Up Table, NN - Neural Network and VPR - Volcanic Plume Removal) on MODIS Thermal InfraRed (...
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...
