Hi, pembaca. Hari ini saya akan memberikan artikel yang lain dari biasanya. hari ini saya akan mengirim artikel berbahasa inggris #ya iyalah, gue gitu loh, plak!
mengapa begitu??? pertama, karna pengunjung blog ini bukan hanya dari indonesia. Kedua, sekalian buat gaya, sekali" pake bahasa inggris hehehe...
ok, ini dia artikel tentang gunung krakatau
Illustration of the Krakatoa
eruption.
Mount
Krakatoa is a volcanic island found in Indonesia. Its most famous
eruption in 1883 is one of the biggest in recorded history. You guessed
it right; Krakatoa belongs to the Pacific Ring of
Fire, the volatile horseshoe-shaped area bordering the Pacific Ocean.
Better known as
Krakatau
in Indonesia, its eruption in 1883 produced a series of tsunamis that
smashed into 165 coastal villages in Java and Sumatra. 36,000 people
perished when those giant waves hit. Most of those who were killed
during the 1883 eruption, which lasted for two days (Aug 26 to 27), were
actually victims of the tsunamis.
Some of the giant waves from
that eruption, which rose up to 40 meters, managed to reach the
southern part of the Arabian Peninsula, some 7,000 km away. When the
2004 Indian Ocean
Tsunami
(a.k.a. the 2004 Indonesian Tsunami) struck, it reminded the scientific
community of the 1883 eruption because of the proximity of their points
of origin.
The eruption also had a large impact on the
global
climate. On the average, temperature dropped by as much as 1.2ÂșC in the
succeeding year. In the years that followed, global climates were very
erratic, stabilizing only 4 years after.
Mount Krakatoa’s lava was
known to be made of dacite or rhyolite. This explains the magnitude of
its eruption. Generally speaking, volcanic eruptions are more explosive
if their lava is composed of dacite or rhyolite. They are cooler and
stickier than basalt, allowing them to accumulate pressure before being
set free.
Although the 1883 eruption destroyed more than 60% of
the volcanic island, a submarine eruption in 1927 produced a new island
in its stead. This volcano is aptly called Anak Krakatau, which is
Indonesian for “Child of Krakatoa”. Anak Krakatau’s radius is estimated
to be 2 kilometers and rises up to a maximum height of 300 meters above
sea level. Studies have shown in to be growing at a rate of 5 meters per
year.
Before 1883, three volcanoes known as Rakata, Danan, and Perbuwatan combined to what then became Krakatoa island.
Mount
Krakatoa is an example of a stratovolcano, a tall, conical volcano with
multiple strata of solidified lava, tephra, as well as volcanic ash.
These type of volcanoes typically have steep sides and usually erupt
frequently & violently. Most of the popular eruptions have been made
by stratovolcanoes. Other known stratovolcanoes are Mount St. Helens
and Mount Pinatubo.
Indonesia
is the country that holds the biggest number of active volcanoes, at
130. Iceland, another volcano-dotted country, holds about the same
number (of volcanoes) but not all are as active as those in Indonesia.
