Volcanoes
Volcanoes are cone shaped hills or mountains
that are formed near a vent that is connected
to a reservoir of molten rock, or magma.
The meaning of the word volcano
is the vent that molten rock, gases, and
solid objects are expelled from the earth.
When the pressure deep inside a volcano
is strong enough, then an eruption occurs.
During an eruption, magma, tephra, and other
materials are forced out of the volcano.
Some eruptions are mild, but others are violent
and dangerous. During a mild eruption only ash
and smoke might exit the volcano. Violent
eruptions send large boulders and rocks
crashing down the side of the volcano along
with extremely heated ash and gases.
Ash and other debris from the volcano can
extend high into the atmosphere and
spread over hundreds of miles away.
Mayon Volcano, also known as Mount Mayon, is an active
strato volcano in the province of Albay, in the Bicol Region,
on the island of Luzon, in the Philippines.Renowned as the "perfect cone"
because of its almost symmetrically conical shape, Mayon forms the
northern boundary of Legazpi City.Local folklore refers to the volcano
as Bulkang Magayon (Filipino: 'Magayon Volcano'),
after the legendary heroine Daragang Magayon (Bikol: 'Lady Beautiful').
On October 13, 2008 it was included in New 7 Wonders of Nature Top 10 list.
However, it did not make the cut to the Top 25 finalists, giving way to the
Puerto Princesa Subterranean River, another site in the Philippines.
Tagatay rises 700 mtr. high on a ridge overlooking Taal Volcano,
a volcano within a lake. Taal Volcano, in the Philippines,
was originally a huge volcano,that towered18,000 feet up into the sky.
It has been called the smallest active volcano,
because it seems small now, but many people
don't realize that it is one of the largest volcanos in the world.
It is located about 70-km south of Manila on an island
inside a lake called Taal Lake.
Kanlaon Volcano, or Mount Kanlaon (also spelled Canlaon),
is a strato volcano on Negros island in the Philippines.
It is found between the provinces of Negros Occidental
and Negros Oriental in the Visayas region (10°24.7'N, 123°7.9'E),
approximately 36 km southeast of Bacolod City.
Mt. Kanlaon is the highest point in Negros
Island and a base diameter of 30 km.
Kanlaon has an elevation of 2,435 meters and
a base diameter of30 km and is dotted with
pyroclastic cones and craters. The summit of Kanlaon
contains a broad elongated northern caldera with a
crater lake. A smaller but moreactive crater lies in the south.
The volcano has three hot springs on its slopes:
Mambucal Hot Springs on the northwest,
Bucalan Hot Spring, Bungol Hot Spring. It’s adjacent volcanic
edifices are Mt. Silay and Mt. Mandalagan, north of Kanlaon.
Canlaon City now stands beside the mountain.
Mt Bulusan is located in the inner district of Sorsogon
where a jeepney takes you to its town and a tricycle
to its entry site. Bulusan Lake- a lake often mistaken
as the volcano’s main crater. It is in fact a body of
emerald green water by the peripheral crater surrounded
by a dense gathering of trees and lush tropical plants.
If not planning to hike farther to the volcano’s summit,
a refreshing one hour walk around this lake is a
worth-trying activity.
And consider it as the beginning
of a more interesting adventure if moving farther ahead.
Expect challenging heights of thicker dense forest on the
way that surprisingly emerge to an open field of towering
grass carpeting the surroundings towards the old crater
valley called Agingay. This hike promises an extreme
jungle experience but without the threat of distressing incidents.
Mount Makaturing – Lanao del Sur
Not as popular as the Taal and Mayon volcanoes but Mount Makaturing,
one of the ‘top ten highest mountains in the Philippines,
is also one of the most active volcanoes in the country.
It has an elevation of 1,940 meters and had erupted 10 times since 1882.
With an elevation of 646 meters only, it is one of
the most active volcanoes in the Philippines and had
erupted 8 times in a span of 21 years from 1866 to 1887.
Its last threatening activity of strong seismic swarm
occurred in 1976 but has not erupted since then.
