Mount Kelud

Today, Mount kelud is very phenomenal with its new dome that exists from its lake. To reach Mount kelud, the visitors can use motorcycle and the direction come from Kediri to Wates continued to Margomulyo – Bambingan till Jurang Gelap or Mount Pedot. From Jurang Gelap till the new dome of Mount kelud is about 2 km and you can go on foot.

Mount kelud has change, it had green crater before explode, but today the beautiful crater is gone and turn up new crater that different from the previous.

The increase of Mount kelud activities from the beginning step to the next step is show phenomenal activities that never happen before. The water temperature in 1990 exploded is about 400 Celsius, and in this activity, the water temperature is increase till 77,50 Celsius, makes thermometer broken caused of high warming. The earthquake is also has increase level, both volcanic and tectonic earthquake. The earthquake is higher compare with exploded in 1990. The white and black smokes that come out from the crater is not happen in 1990.

The climax activity of Mount kelud is to turn up a dome from the lake crater in November 5, 2007 with diameter 100 meters and 20 meters height from crater water. Today, the Lava Dome still growing slowly till 200 meters height and widened to southwest side of the lake crater wide.
The first white and black smoke are detected in November 4, 2007. At that time is 200 meters height and today the wind has blow them to south side. The white smoke is come out from the dome and blow to the air till 1.000 meters height.

If this is really the end of Mount kelud and the status is normal, with Mount kelud condition at the present, then Mount kelud has a new face. With its Dome that comes from the crater, Mount kelud is more beautiful than before, add with the other phenomenal that never happen before.
Mount kelud changes with its new Dome are very interesting for visitors. The visitors can see and enjoy its new dome if the condition is really safe to be visited. The Dome is seems to be Mount kelud’s son. There is no crater-lake or green water in Mount kelud, but the new kelud presents its new dome. Fantastic and curious nature panorama.

SUBMARINE MONUMENT SURABAYA
(SS type whiskey class submarine built in Vladivostok Russia in 1952)

As you continue on your journey, visit the Monkasel, the original KRI Pasopati 410 submarine next to the Surabaya Plaza shopping center. It is 76.6 meters long and 6.3 meters wide. It was moved from Ujung to this location on July 1st, 1995, after the museum was officially opened by Arief Kushariadi, the Naval Commander of the Republic of Indonesia on June 27, 1998.

KRI. Pasopati with 410 side number belongs to SS type whiskey class built in Vladivostok Russia in 1952. It has been with Indonesia Navy since 29 January 1962 and carried out dutief to destroy enemy line, to be surveillance and acts as silent raids. KRI. Pasopati bought ctivelly for independence and national supremacy in the past. It was the front line during Trikora Operation, gave psicological presure so that west Irian could be gain back and other important operation.

The following month, on July 5, 1998, it was opened to the public as a marine tourist destination. Boats and a diorama also complete the monument, which also functions as a museum. The visitors who want to travel by boat along the Kalimas River to view the monument can launch from ‘”Prestasi Park” behind the Grahadi Governor Mansion.

Monkasel is equipped with a multimedia building which presents a program in recognition of the Indonesian Navy. Monkasel is open from Monday through Friday from 0830-2200 WIB. To receive more information please contact 031-5490410. The following facilities are provided: parking, a canteen, a stage, and an amusement area for children. It is easily reached by public transportation.

Lapindo Hot Mud

This is not one of East Java cultural heritage or even Tourism destination, Lapindo hot mud is such a tragedy for
Sidoarjo people as victims of this thing happened. By this natural disaster, we should have to be more concern about the Earth and the society within the world.

The Sidoarjo mud flow or Lapindo mud, also informally abbreviated, a contraction of Lumpur Sidoarjo (lumpur is the Indonesian word for mud), is a mud volcano[1] in the subdistrict of Porong, Sidoarjo in East Java, Indonesia that has been ongoing since May 2006. Approximately 2,500 m³ (88,000 cubic feet) of mud are expelled per day, which is equivalent to the contents of a dozen Olympic-size swimming pools.[2] It appears that the flow will continue indefinitely. As of November 2008, the Sidoarjo mud flow is contained by levees, but further breakouts are possible.

Mud volcano systems are fairly common on Earth, and particularly in East Java province. Beneath the island of Java is a half-graben lying in the east-west direction, filled with overpressured marine carbonates and marine muds.[4] It forms an inverted extensional basin which has been geologically active since the Paleogene epoch.[5] The basin started to become overpressured during the Oligo-Miocene period. Some of the overpressured mud escapes to the surface to form mud volcanoes, which have been observed at Sangiran Dome and near Purwodadi city, 200 km (124 miles) west of Lusi.

The East Java Basin contains a significant amount of oil and gas reserves and therefore the region is known as a major concession area for mineral exploration. The Porong subdistrict, 14 km south of Sidoarjo city, is known in the mineral industry as the Brantas Production Sharing Contract (PSC), an area of approximately 7,250 km² which consists of three oil and gas fields: Wunut, Carat and Tanggulangin. As of 2006, three companies — Santos (18%), MedcoEnergi (32%) and PT Lapindo Brantas (50%) — had concession rights for this area; PT Lapindo Brantas acted as an operator

On May 28, 2006, PT Lapindo Brantas targeted gas in the Kujung Formation carbonates in the Brantas PSC area by drilling a borehole named the ‘Banjar-Panji 1 exploration well’. In the first stage of drilling the drill string first went through a thick clay seam (500–1,300 m deep), then sands, shells, volcanic debris and finally into permeable carbonate rocks.[1] At this stage the borehole was surrounded by a steel casing to help stabilise it. At 5:00 a.m. local time (UTC+8) a second stage of drilling began and the drill string went deeper, to about 2,834 m (9,298 ft), this time without a protective casing, after which water, steam and a small amount of gas erupted at a location about 200 m southwest of the well.[7] Two further eruptions occurred on the second and the third of June about 800–1000 m northwest of the well, but these stopped on June 5, 2006.[7] During these eruptions, hydrogen sulphide gas was released and local villagers observed hot mud, thought to be at a temperature of around 60 °C (140 °F).[8]

From a model developed by geologists working in the UK,[7] the drilling pipe penetrated the overpressured limestone, causing entrainment of mud by water. The influx of water to the well bore caused a hydrofracture, but the steam and water did not enter the borehole; they penetrated the surrounding overburden and pressured strata. The extra pressure formed fractures around the borehole that propagated 1-2km to the surface and emerged 200 m away from the well. The most likely cause of these hydraulic fractures was the unprotected drill string in the second stage of drilling.[7] Borehole protection by steel casing is a common procedure in oil or gas exploration.
