On Saturday, Japan's Mount Ontake volcano erupted without warning, surprising several hundred nearby hikers. Plumes of volcanic gas and ash overtook the fleeing hikers and buried nearby lodges and outbuildings. Though most of the people on Mount Ontake that day were able to escape.
When these earthquakes occur continuously the result is volcanic or harmonic tremor. Mount St. Helens exhibit these long period earthquakes months in advance of 1980's eruption. The volcanic tremor can be used to warn of an impending eruption allowing people living near the volcano can to be evacuated to safer areas.
