Doomsday volcanoes

Gr 9 Up-The threats and possible devastating effects posed by three Icelandic volcanoes-Katla, Hekla, and Laki-after the April 2010 eruption of neighboring volcano Eyjafjallajokull are analyzed in this documentary. Subsequent disruption of transatlantic flights sparked concerns among volcanologists that Iceland's seismic activity could have disastrous consequences for the rest of the northern hemisphere. Geologists and historians look to past eruptions to predict the level of danger from the other three volcanoes. Pointing to lava flow, piles of ash, and clouds of poisonous sulfur dioxide, scientists present doomsday scenarios that may affect Europe in the near future. The visuals capture the exotic landscapes well, and computer animation is used to good demonstrative effect. Scientists are shown in the field using their equipment to try to predict the upcoming danger, but there is little explanation of what can be accomplished. An exception is the inventor who has created a sensor to detect ash clouds on commercial aircraft in hopes that pilots can avoid flying through it and damaging their engines. Overall, this is a high-interest piece for those with a special interest in volcanoes, but its focus on sensationalism over using science to solve a problem keeps it from being immediately useful in many classrooms.-Ryan Henry, Daviess County Public Library, Owensboro, KY (c) Copyright 2013.
