Mayon Volcano in the Philippines with Legazpi City in the foreground.

Mayon, one of the most active volcanoes in the Philippines, is causing concern due to increasing signs of activity. Renato Solidum, the director of PHIVOLCS (Philippine Institute of Volcanology and Seismology), said that there has been increasing seismic activity and "glow" at the summit of the volcano near (~20 miles / 45 km) Legazpi City. However, even after this sense of increasing activity, the alert level (1) has not changed, but local residents were altered to the new activity. This means that there is low-level unrest with slight increase in seismicity. The last notable eruption in 2006 at Mayon (oddly called a "silent eruption" in the linked article) produced a lava flow. There were also minor phreatic explosions in 2008.
