Which Philippines volcano may be about to erupt?
Mount Pinatubo, the volcano that devastated a wide swath of the northern Philippines last year and spread ash around the globe, erupted again today, spewing steam and volcanic sand in what scientists said was a “moderate” explosion. There were no immediate reports of damage or casualties from the eruption, which scattered ash up to 18 miles away. Villagers living within six miles of the volcano were told to be ready to evacuate. Although scientists say the latest volcanic activity shows no sign of approaching the awesome power of last year’s eruption, today’s blast served as a reminder that … Sources: http://www.encyclopedia.com/doc/1P2-1015376.
Prediction of volcanic activity (also: volcanic eruption forecasting) is an interdisciplinary scientific and engineering approach to natural catastrophic event forecasting. Volcanic activity prediction has not been perfected, but significant progress has been made in recent decades. Significant resources are spent to monitoring and prediction of volcanic activity by the Italian government through the Istituto Nazionale di Geofisica e Vulcanologia INGV, by the United States Geological Survey (USGS), and by the Geological Survey of Japan. These are the largest institutions that invest significant resources monitoring and researching volcanos (as well as other geological phenomena). Many countries operate volcano observatories at a lesser level of funding, all of which are members of the World Organization of Volcano Observatories (WOVO).

Philippines authorities Tuesday started evacuating about 50,000 people living around the island nation’s most active volcano after it oozed fiery lava and belched clouds of ash. A large-scale eruption was forecast as imminent. The Philippine Institute of Volcanology and Seismology raised the alert level up a notch on Monday night to level 3. Scientist Alex Baloloy told the Philippine News Agency (PNA) that under level 3, “a full-blown eruption is expected to take place within weeks to days.” Sources: http://edition.cnn.com/2009/WORLD/asiapcf/12/15/philippines.volcano.
