The Taal-vvolcano is situated in one of the most beautiful nature-areas
in the Philippines.
The volcano lies in the middle of a big lake, The Taal lake, a former
crater of 30 kilometers
width. The volcano itself also have a lake in its crater, and in the
crater is another volcano.

The Taal seismic monitoring network recorded a series of volcanic earthquakes
on January 9.
Of the total nine (9) events recorded, two (2) of these earthquakes
were felt first at 07:45 PM
and then on 07:46 PM. The 07:45 PM earthquake was felt in Pira-piraso
at Intensity III while
the 07:46 PM event was felt in the same area at Intensity II.
Since 29 October 2004, the alert status of Taal Volcano has been raised
to Alert Level I due
to an increased level of earthquake activity, which is presently considered
as a low-level episode
of unrest. The two (2) earthquakes felt today are part of this on-going
seismic unrest in Taal
Volcano. So far, the Buco Volcano Observatory has not recorded any intensification
activity that may indicate an imminent eruption. However, PHIVOLCS reiterates
recommendation that the Main Crater area be off-limits because sudden
steam explosions may
occur or deadly concentrations of toxic gases may accumulate. There
are also several fissures
traversing the Daang Kastila Trail which, when reactivated with steam
emission, are also
potentially hazardous to the people.
Some 300 families left Barangay Pulo in Talisay Sunday night
and sought shelter at the public
market and Balas High School. PHIVOLCS advised the public to remain
calm, adding that
volcanic quakes do not usually result in tsunamis.

Two weeks after Taal Volcano started showing signs of activity, the
Philippine Institute of
Volcanology and Seismology (Phivolcs) has maintained the alert level
in a 10-km radius
around the picturesque volcano.
The Phivolcs report said its seismic network registered
a total of 31 high-frequency
earthquakes in a span of seven days. It noted that while there had been
no visible "steaming
activity of reactivated vent" at the volcano's main crater on Tuesday,
there had been "weak
steaming (about) 5 meters high" on Nov. 10. Last week, Phivolcs
noted the temperature and
acidity in the lake were at 27 degrees

From a report from PHIVOLCS on October 29, 2004, 08:00 HRS
The Taal seismic monitoring network began to record significant volcanic
September 23. In general, the number of these type of earthquakes occurring
since then and
up to the present has increased, with a maximum 13 earthquakes on October
Some of these earthquakes were instrumentally recorded with relatively
although none were felt by residents on Volcano Island. Initial earthquake
epicenters dispersed in the vicinity of Main Crater and to the North-Northwest
Binintiang Malaki and to the South-Southeast near Calauit.
Surface observations, however, did not indicate any significant change
in the thermal and
steam emission characteristics of the Main Crater Lake area.
The increased seismicity of Taal Volcano Island is an indication of
a low-level episode of unrest
although at this time, there is still no clear indication of an impending
The ongoing seismic unrest could intensify in the coming days and weeks
so that PHIVOLCS
is recommending appropriate vigilance by the public when visiting the
island. As one primary
safety measure, PHIVOLCS recommends as off-limits the Main Crater area
steam explosions may occur or high concentrations of noxious gases may
There are also several fissures traversing the Daang Kastila Trail which,
when reactivated with
steam emission, are also potentially hazardous to people.
The Taal-volcano has had 34 eruptions since 1572. The most powerfull
Since 1991 Taal has been restless, with several quakes, emissions of
gas, cracks in the
mountain and high temperatures in the lake.
The Taal-volcano is counted in between - for people - the most dangerous
volcanoes on earth.
The capital of the Philippines, Manila, is only 50 kilometers further
In an explosive eruption in 1911 as many as 1,335 people
were killed by gas and heat.
In 1965 more than 200 were killed by gas, heat and tsunamis. The last
big eruption was in 1977.
