Active volcanoes / Aktive vulkaner:

Mayon, Philippines    

From the eruption February 24th, 2000

Mayon-volcano in the Philippines is a stratovolcano, and the most active
volcano in the islands. Mayon is situated about 330 km south of Manila, in the province
of Albay, and reaches 2.460 meter asl. Since 1616 it has erupted 47 times.
12 of these has forced damage to property and people.

Monday, September 13th, 2004
Volcanic material was emitted by Mayon volcano late yesterday, setting fire to grass on the
volcano's slopes. A crater glow was visible to the naked eye, indication the proximity of magma
to the surface. Mayon volcano remains on alert level two, which means that the volcano is
undergoing abnormal activity but an eruption is not yet imminent. There is a six kilometer
exclusion zone around the crater.

May 20th, 2004
Phivolcs Tuesday declared a six-kilometer radius from the top of Mayon Volcano as a
"permanent danger zone" due to instrument reading indicating signs of moderate volcanic
unrest in the world-famous perfect cone.

This alert condition signifies a volcano instability that may eventually lead to ash emissions
or eruption. Phivolcs reported that a total of three volcanic quakes were recorded the past
week suggesting a renewed period of unrest for Mayon volcano. A glow in the crater and
a moderate steaming activity were also noted.

Mayon's sulfur dioxide emission increased from the normal level of 500 tons per day
to 1,169 tons per day as of May 12

November 7th, 2002
According to news articles, the Alert Level at Mayon was raised from 0 to 1 (on a scale of 0-5) after increased seismicity and gas emission were recorded. The amount of SO2 emitted increased from ~950 tons/per day during the previous week, to ~2,670 tons on 29 October. Residents near the volcano were notified that they must not enter the 6-km radius Permanent Danger Zone, especially on the SE side of the volcano.

July 27th 2001
Following initial eruption at 7:56 AM yesterday, two more eruption episodes occurred.
The second explosive eruption commenced at 2:20 PM until 3:00 PM yesterday and the
third event was recorded from 5:49 PM to 6:10 PM yesterday. These eruptions produced
life-threatening pyroclastic flows, which swept mainly the Bonga Gully in the southeast and
the Basud Gully to the East. Smaller pyroclastic flows ran through the Miisi and Anoling
Gullies in the south, and other flows occurred in the southwest and western sectors.

All pyroclastic flows were contained within the six (6) kilometer-radius Permanent Danger
Zone (PDZ). Inclement weather precluded direct observation of the ash plume for the second
and third eruption episodes but based on ashfall in Legaspi City and neighboring towns, it is estimated that the ash columns were similar to the first eruption of 7:56 AM and reached 10 kilometers high and fanned through the south-southwest and southeast.

The Mayon volcano in the Philippines erupted today,panicking nearby residents less than
a month after aseries of eruptions. The volcano sent a huge cauliflower-shaped column of
ash and smoke into the air, with flows of lava down its slopes.

Late yesterday, the Philippine Institute of Volcanology and Seismology raised the fourth-level
of a five-step volcano alert around Mayon, calling for the evacuation of residents within a six kilometre danger zone around the volcano.
