INDONESIA The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the EURASIAN plate and the INDO-AUSTRALIAN plate.   Source: http://en.m.wikipedia.org/wiki/List_of_volcanoes_in_Indonesia

In 2012, Indonesia had 127 active volcanoes. Indonesia is the land of volcanoes located at the Pacific Ring of Fire. In 2012, Indonesia had 127 active volcanoes. The devastating earthquake and tsunami event of December 26, 2004 is thought to bring disruption to the volcanoes' eruption pattern.

Java Island

JAVA ISLAND Java is almost entirely of volcanic origin, and there are numerous volcanoes (45 of which are considered active volcanoes). Volcanoes have played a vital role in the geological and human history of Java. Land is created on Java as a result of lava flows, ash deposits, and mud flows (lahars). Volcanoes are a major contributor to the immense fertility of Java, as natural erosion transports volcanic material as to the island's plains, forming thick layers of fertile sediment.

JAVA ISLAND In 2014, the Indonesian population reached 253 million people. Java island is the most populated island in the world, and there are more 143 million people living in this island. Languages use in Java island are Javanese, Sundanese, Madurese, and the national language of Indonesian. Source http://en.m.wikipedia.org/wiki/List_of_volcanoes_in_Indonesia

The three major languages spoken on Java are Javanese, Sundanese and Madurese. 

WELCOME TO CENTRAL JAVA (THE LAND WITH A VERY RICH CULTURE) In this part of the island, the population consists of Javanese and Chinese. Most Javanese people are farmers, and the Chinese people are doing business/trade.

August 1883: More volcanic activities and volcanic eruption occurred August 1883: More volcanic activities and volcanic eruption occurred. November 13-14, 1887: volcanic explosion. May 1-25, 1902:small mudflow and pyroclastic flow.

October 1903: Eruption at Kembang crater and falling ashes October 1903: Eruption at Kembang crater and falling ashes. 1906: eruption, falling ashes that damaged crops and caused house fire. 1908: Increasing volcanic activity (buzzing sound coming from the inner mountain). 1910: The volcanic activity (buzzing sound can be heard from the city of Temanggung).

1970: Earthquake at Sigedang village followed by white smoke coming out from the summit. Then, smoke came out vertically above the crater followed by blast with thick smoke and buzzing sound. At night, smoke looked red.

November 2011: increasing volcanic activity November 2011: increasing volcanic activity. November 2011 – March 2012: smoke and volcanic gases came out from the crater and crater’s wall. December 5, 2011: volcanic activity raised from level 1 to level 2 followed by earthquakes coming from deep and shallow volcanic activities. March 2012: volcanic activity decreased and came back to level 1.

Hazardous eruption of 1982 The last major eruption on Galunggung was in 1982, which had a volcanic explosivity index (VEI) of 4. Volcanic hazards include pyroclastic flow, huge falling ash, lapilli, blast, landslide, lahar, earthquake, volcanic gases,and volcanic aerosol. The eruption lasted for 9 months. This eruption also brought the dangers of volcanic ash to aviation to worldwide attention. Source: http://en.wikipedia.org/wiki/Galunggung

The first historic eruption of Galunggung was in 1822 The first historic eruption of Galunggung was in 1822. Since then the volcano has erupted four times, most recently in 1984. This photo shows a column of ash rising above the summit during the large (VEI=4)Vulcanian-type eruption. Eruption columns at Galunggung reached heights as great as 15 miles (24 km).

ERUPTION HISTORY: Two eruptions at Galunggung have caused fatalities ERUPTION HISTORY: Two eruptions at Galunggung have caused fatalities. During the 1822 eruption (VEI=5), and mudflows killed 4,011 people and destroyed 114 villages. During the 1982 eruption (VEI=4) about 68 people died, mostly from indirect causes (traffic accidents, old age, cold, and lack of food). Estimated damage was $15 million and 22 villages were left uninhabitable. The 1984 eruption was phreatic and lasted about two weeks. Source: http://en.wikipedia.org/wiki/Galunggung

The April 1982-January 1983 eruption destroyed the 1918 lava dome and produced a new cinder cone in a new crater. The crater was about 2,000 feet (600m) across and about 1,000 feet (300 m) deep. The cone grew to 250 feet (75 m) and was 650 feet (200 m) in diameter. Photo by Jack Lockwood, U.S. Geological Survey, July 31, 1982. Source: http://en.wikipedia.org/wiki/Galunggung

View of new cinder cone. As the 1982-1983 eruption waned a crater lake began to form. The presence of the lake, high rainfall, and the large volume of exposed pyroclastic material on the volcano have made the hazard associated with secondary lahars very high.

During the 1982 eruption two jumbo jets entered the ash clouds at an altitude of about 6 miles (10 km). Their engines stalled and windshields were abraded. Fortunately, the pilots were able to restart the engines. Source: http://en.wikipedia.org/wiki/Galunggung

MT. MERAPI

Mt. Merapi Merapi means producing fire. ”Api” is “fire” in Indonesian Mt. Merapi Merapi means producing fire. ”Api” is “fire” in Indonesian. Historically, Mt. Merapi has shown the volcanic activities (smoke emitted from the summit in 300 days per year). I remember when I was young, Most of the time I saw smoke coming out from the peak of Mt. Merapi.
