Volcanic ash layer depth: Processes and mechanisms
The long duration of the 2010 Eyjajallajökull eruption provided a unique opportunity to measure a widely dispersed volcanic ash cloud. Layers of volcanic ash were observed by the European Aerosol Research Lidar Network with a mean depth of 1.2 km and standard deviation of 0.9 km. In this paper we evaluate the ability of the Met Office’s Numerical Atmospheric-dispersion Modelling Environment (NA...
متن کاملEnvironmental hazards of £uoride in volcanic ash: a case study from Ruapehu volcano, New Zealand
The vent-hosted hydrothermal system of Ruapehu volcano is normally covered by a c. 10 million m3 acidic crater lake where volcanic gases accumulate. Through analysis of eruption observations, granulometry, mineralogy and chemistry of volcanic ash from the 1995^1996 Ruapehu eruptions we report on the varying influences on environmental hazards associated with the deposits. All measured parameter...
متن کاملDevelopment of a Prediction Scheme for Volcanic Ash Fall from Redoubt Volcano, Alaska
The purpose of this project is to develop a volcanic plume prediction model for volcanoes located in the Cook Inlet area, Alaska. Knowing where the ash plume is and predicting where it will go are important for public health and safety, as well as for flight operations and mitigating economic damage. For near-real-time plume prediction, acquisition of upper-air wind data is the essential part o...
متن کاملVolcanic Ash Observation in Active Volcano Areas using Teleoperated Mobile Robots
Observation of an active volcano is very important to determine a strategy for estimating its eruptive activity and providing residents with an evacuation warning. However, it is too dangerous for humans to install cameras during eruptive activity to determine the status of a volcano. Furthermore, permanently installed cameras might be damaged by eruptions, and craters can emerge in unanticipat...
متن کاملVolcanic Ash and Daily Mortality in Sweden after the Icelandic Volcano Eruption of May 2011
In the aftermath of the Icelandic volcano Grimsvötn's eruption on 21 May 2011, volcanic ash reached Northern Europe. Elevated levels of ambient particles (PM) were registered in mid Sweden. The aim of the present study was to investigate if the Grimsvötn eruption had an effect on mortality in Sweden. Based on PM measurements at 16 sites across Sweden, data were classified into an ash exposed da...
