Blue Lagoon Galapagos Islands in Ecuador
The Galápagos Islands are an archipelago
of volcanic islands distributed on either side of the Equator in the
Pacific Ocean, around 906 kilometers (563 miles) west of continental
Ecuador, of which they are a part. The Galápagos Islands and their
surrounding waters form an Ecuadorian province, a national park, and a
biological marine reserve. The islands have a population of more over
25,000, and their main language is Spanish. These attractive islands are
so popular for their huge number of endemic species and were studied by
Charles Darwin during the voyage of the Beagle. His deep observations
and collections contributed to the inception of Darwin’s theory of
evolution by natural selection.
These impressively beautiful islands are
found at the coordinate’s 1°40’N – 1°36’S, 89°16′ – 92°01’W. Because
straddling the equator, islands in the chain are situated in both the
northern and southern hemispheres, with Volcán Wolf and Volcán Ecuador
on Isla Isabela being directly on the equator. Española Island, the
southernmost islet of the archipelago, and Darwin Island, the
northernmost one, are range more than a distance of 220 kilometers. The
IHO (International Hydrographic Organization) considers them wholly
within the South Pacific Ocean, however. The Galápagos Archipelago
consists of 7,880 kilometers of land spread over 45,000 kilometers of
ocean. Moreover the largest of the islands, Isabela, measures 2,250 sq
mi/5,827 kilometers and makes up close to three quarters of the total
land area of the Galápagos. Volcán Wolf on Isabela is the highest point,
with an elevation of 1,707 meters above sea level.
Moreover the group consists of 18 main
islands, 3 smaller islands, and 107 rocks and islets. And these islands
are located at the Galapagos Triple Junction. The archipelago is located
on the Nazca Plate, which is moving east/southeast, diving under the
South American Plate at a rate of about 2.5 inches per year. It is also
atop the Galapagos hotspot, a place where the Earth’s crust is being
melted from below by a mantle plume, making volcanoes. It is projected
that the first islands formed here at least 8 million and perhaps up to
90 million years ago. Though the older islands have disappeared below
the sea as they’ve moved away from the mantle plume, the youngest
islands, Isabela and Fernandina, are still being formed, with the most
recent volcanic eruption in April 2009 where lava from the volcanic
island Fernandina started flowing both towards the island’s shoreline
and into the center caldera.
The history tell us, that the first recorded visit to these islands
occurred by chance in 1535, when the Bishop of Panamá Fray Tomás de
Berlanga went to Peru to arbitrate in a dispute between Francisco
Pizarro and Diego de Almagro. De Berlanga was blown off course; however
he ultimately returned to the Spanish Empire and described the
conditions of the islands and the animals that inhabited them. Therefore
the group of lovely islands was shown and named in Abraham Ortelius’s
atlas published in 1570. The first crude map of the islands was made in
1684 by the buccaneer Ambrose Cowley, who named the individual islands
after some of his fellow pirates or after British royalty and noblemen.
Though these names were used in the authoritative navigation charts of
the islands organized during the Beagle survey under Captain Robert
Fitzroy, and in Darwin’s widespread book The Voyage of the Beagle. As
the time passes, the new Republic of Ecuador took the islands from
Spanish ownership in 1832, and afterward gave them official Spanish
names. The older names remained in use in English language publications,
including Herman Melville’s The Encantadas of 1854.
