A summary of last week's report can be read and the comment or warning of IMO's hydrologist when appropriate. Some of the web-site's litterature has been relocated, e.g. articles on pollution, radiation, ozone and lightnings. Over the next few weeks /about-imo/news/nr/1538

  not during the first 24 hours. The figure on the right (above) shows an image of the eruption cloud at 22:00 UTC. The image is from the Icelandic Met Office weather radar located at Keflavik International Airport, at 220 km distance from the volcano. The cloud extends above a large part of Vatnajökull ice cap. The line marks the approximate location of Grímsvötn volcano. The last eruption /about-imo/news/nr/2174

  An eruption in Grímsvötn in May 2011. It is assumed that as much ash was released into the air during the first 24 hours of this eruption as in total during the 40 days of the Eyjafjallajökull eruption a year earlier. Measurements and simulation of volcanic ash /about-imo/news/nr/2421

  high). A strong reflection may be observed although the precipitation does not reach the ground, i.e. when water droplets evaporate while falling. Combined images are also presented on IMO's web. There, the radar images are combined with a thermal image from the weather satellite Meteosat-9, which belongs to EUMETSAT.
