Rocket rumbles give volcanic insights

Science
What do volcanoes and rockets have in common? "Volcanoes have a nozzle aimed at the sky, and rockets have a nozzle aimed at the ground," explains Steve McNutt, a geosciences professor at the University of South Florida in Tampa. It explains why he and colleague Dr Glenn Thompson have installed the tools normally used to study eruptions at the famous Kennedy Space Center. Comparing the different types of rumblings could yield new insights. In the case of rockets, the team thinks their seismometers and infrasound (low-frequency acoustic waves) detectors might potentially be used by the space companies as a different type of diagnostic tool, to better understand the performance of their vehicles; or perhaps as a way to identify missiles in flight. In the case of volcanoes, the idea is to take...

Volcanic eruption in Japan spreads ash in 4 cities, towns

Technology
A volcano in southwestern Japan is erupting for the first time in six years, spewing ash over nearby farms, cities and towns. Japanese broadcaster TBS showed elementary school students wearing helmets and masks Thursday on the way to their school at the foot of the Shinmoedake volcano. Residents also described hearing rumbles from the volcano and ash fell in at least four cities and towns in Miyazaki prefecture. Street cleaners swept ash from city streets, and farmers used leaf blowers to clear the growing piles of ash from the tops of their plastic greenhouses. The volcano on the border of Kagoshima and Miyazaki prefectures started erupting Wednesday for the first time in six years. On Thursday, an ash plume rose 2,000 meters (6,560 feet) from the crater, the Japan Meteorological Agency ...
