Anak Krakatau continues to attract tourist and researchers because it represents a Natural Laboratory in Geology, Conservation, Biology and, of course, Volcanic Activity.
"The History of Anak Krakatau..."
Brown and almost barren, Anak Krakatau rises out of the Sunda Strait, the narrow band of the Indian Ocean that separates the Indonesian islands of Sumatra and Java. This detailed image of the young volcano was taken by the Ikonos satellite on June 11, 2005. The volcano’s circular crater sits southwest of the center of the island and is surrounded by fresh lava flows and ash. The black shores of the island are scalloped where the flows have solidified in the ocean.
Anak Krakatau emerged from the sea less than 80 years ago, and is a natural laboratory to watch the development of an ecosystem. Since the soil is new, it was uncontaminated with seeds. All of the plants seen growing on the island came from seeds that drifted in on the sea or blew across the ocean on the wind. As a result, the plants are clumped on the shallowly sloped eastern shores of the volcano where loose ash and volcanic sand cover the ground. In contrast to the solid rock seen elsewhere on the island, these loose soils allow plants to take root easily.
Most of the plants seen here are grasses, ferns, and herbs that blew in on the wind or coastal trees like coconut, shrubs, and ground vines that floated ashore. Inland, clumps of plants are probably Australian Pine trees and a wild plant related to the sugar cane, both of which disperse seeds on the wind.

This strip of ocean was not empty before the island pushed its way up. Phoenix-like, Anak Krakatau rose from the crater left when its parent, Krakatau, disappeared in one of the most notorious volcanic eruptions in history. Over a two-day period, August 26-27, 1883, Krakatau erupted with such violence that two-thirds of the island, about 23 square kilometers, sank into the Sunda Strait. Prior to that date, the Krakatau volcano peaked 450 meters above sea level; after the eruption, the top of the volcano sat 250 meters below sea level. Anak Krakatau, which means “child of Kratatau,” replaced the craters destroyed in the 1883 eruption.
The explosions heard in the 1883 eruption remain the loudest noise on human record. The sound was heard across the Indian Ocean, as far away as Rodriguez Island, 4,653 kilometers to the west, and Australia, 3,450 kilometers to the east. The massive eruption also generated a series of tsunamis, which produced waves as much as 30 meters tall. In contrast, the December 26 tsunami that devastated the region in 2004 reached up to 20 meters in height in a few locations. The huge waves created when Krakatau erupted were responsible for most of the 36,000 deaths associated with the eruption.
Like most of the approximately 130 active volcanoes in Indonesia, Krakatau was formed along the Sunda Arc, a 3,000-kilometer-long curve where the Australia Plate sinks beneath the Eurasia Plate. Where these two sections of the Earth’s crust meet, earthquakes and volcanic eruptions are common. Krakatau and the Sunda Strait sit at the hinge of the curve between Sumatra and Java, making this a region particularly prone to geologic activity.

No risk-taking
Safety is paramount at Anak Krakatau. When we arrived at the shore of the volcanic island, the local guard stopped us going any further. "The baby (the volcano) has been coughing for the past few days," he warned.
A glimpse of volcanic dust and gas was all the convicing we needed. Consequently, we circumnavigated the volcano - which grow steadily by four meters per year - by boat.
Sunset at Anak Krakatau is magnificent and if you're lucky and the volcano is friendly, you can start your trip by setting up a tent on the fooththills and explore around the volcano.
To climb the volcano you need special permission from the Director General of Protection and Natural Preservation (PPA) of the Deprtment of Forestry and an experienced tour guide.
People who have walked up Anak Krakatau say it is not an easy walk, with the heat from the volcano burning your shoes as you walk and the sand shifting under youon the steep slopes near the summit.
The island is a wonderful place for swimming and diving with beautiful coral and colorful fish and if you're lucky you could meet a clownfish of Finding Nemo fame. Anak Krakatau continues to attarct tourist and researches because it represent a natural laboratory in geology, conservation, biology and, of course, volcanic activity.
How to get there?
Located in Sunda Strait in Lampung Province, it is not hard to get to the island of Anak Krakatau. Travel by jet-foil from Tanjung Priok harbour (Jakarta) or by a traditional Phinisi Nusantara ship, or you can rent a speed boat or a fishing boat which can carry up to 20 people at a number of points along the Banten coast, including Labuan and Lippo Carita Marina.
You can also go from Kalianda, south of Lampung in Sumatra. I stayed at Krakatau Nirwana Resort and rented a speedboat which can carry 15 people. The trip took two hours. If you prefer to go from coast of Java island, you can stayed at Lippo Carita Cottages or some resort and hotel at Labuan. You can also go from Marina Ancol or Tanjung Priok and stayed at Putri Duyung Cottages or in a hotel downtown Jakarta.
"It depends on the waves," explain Agung Widodo, a nautical javascript:void(0)researcher from Lampung University who accompanied us. "If the weather is good, we can get there in only 90 minutes," With a spectacular backdrop we were in no hurry and stopped at the nearby island of Setiga, Sibesi and Panjang.
Krakatoa Festival
August is the best time to visit Anak Krakatau. The Lampung government organizes an annual festival to celebrate the birth of the "child" in August 1927.
The festival aims to attract both local and foreign tourist to Lampung. The government hopes to attract 1.2 million local and 24,000 foreign visitors in 2009 - Visit Lampung Year.
Chief of Tourism House in Lampung, say s the festical is a-long term project. "We are not just focusing on Anak Krakatau. The government will also host an international kite festival, art exhibitions and promote beach activities," he says.
