Dormant Volcanoes in Honduras
Four Classic Volcanoes in Honduras
One of the most exotic countries in Central America is Honduras. It
consists of very high elevations and low valleys and green luscious tropical
rainforest. Another one of its interest attractions is the dormant volcanoes
that can be found there.
Itís estimated that Honduras is covered with 40,000 square
kilometers of trails, about 100 necks have been identified, 32 of these are
located around Tegucigalpa the capital, and most of them are unnamed. Most
volcanic cones are located in the central, southern, and eastern parts of
Honduras. This area include the ďclassicĒ volcanoes in Honduras and the most
volcanoes in Honduras are known as the classics such as Volcan el Tigre which is
a strato volcano, Isla Zacate Grande which is also a strato volcano, Lake Yojoa
which is a volcanic field, and Utila Island which is covered with pyroclastic
cones. These volcanic mountains have an altitude less than 1,400 meters,
they are extremely steep and have numerous isolated narrow valleys. They have
erupted in the last 10,000 years, but not in historical time.
Volcan El Tigre is considered one of the most impressive in
Honduras. It is located in the Southern Coast of Honduras in an Island called
Isla del Tigre, in the Gulf of Fonseca. It has an elevation of 783 meters. It
has beautiful scenery. It is near the equator and coast, thus the climate is
extremely hot and humid. You can reach the Island from Tegucigalpa. The land you
cross to reach the island is full of rainforest and the elevation increases as
you get nearer the Island.
Zacate Grande Volcano is located in Isla Zacate Grande. Itís a Holocene Strato volcano. Itís an Island 7X10 km wide across a narrow strait from the end of a peninsula surrounded on three sides by the Gulf of Fonseca and Chismuyo Bay. Itís located North of Isla El Tigre, however Zacate Grande is extremely eroded. It is covered with deep valleys from the top of the volcano to the base of the volcano.
The Lake Yojoa volcanic field is located in northern end of
north-central Honduras, which also contains magnificent scenes. Itís made up of
a group of Pleistocene-to-Holocene scoria cones and collapse pits. A variety of
rocks from tholeiitic basalts to trachybasalts, trachyandesites, and trachytes,
can be found there. Several of the pyroclastic cones contain well-preserved
craters. Most of the pyroclastic cones consisting of basaltic scoria and
agglutinate, are 100-200 M in height. There are indications of lava flows from
in all directions from the cone. A few Quaternary lava flows occure in the Sulu
graben along the Carretara del Norte north of Lake Yojoa.
Utila Island is the smallest of the Caribbean Bay Islands in
Honduras. It is covered with pyroclastic cones, and itís a Holocene volcano
Island. Basaltic lavas and tuffs were erupted onto a coral-capped erosional
surface. Stuert Hill, which is also pronounces as Stuart Hill, is a pyroclastic
cone that was constructed at the center of the volcanic terrain, and Pumpkin
Hill is a small littoral cone located along the NE coast of the island. This is
also the highest point of the island, which rises 74 M above sea level.
There are many places in Honduras to admire indications of volcanoes and enjoy nature, but these four volcanoes are considered to be one of the most exciting volcanoes in Honduras and worth it to go sightseeing.
