We made a Shield Volcano, a Cinder Cone Volcano and a Stratovolcano (Composite Volcano). We used baking soda and vinegar in the shield volcano, ammonium nitrate and zinc dust in the cinder cone volcano and ammonium dichromate in the stratovolcano. The eruptions were great! These are the products that we used for the cinder cone volcano: http://www.hometrainingtools.com/zinc-oxide-powder-30-g/p/CH-ZNOXIDE/ and http://www.hometrainingtools.com/ammonium-nitrate-30-g/p/UN1942/

S/V Ohana Kai takes an up close look at Anak Krakatau and she delivers quite an eruption!!! 10/23/07 This was a day after the first eruptions and we were on our way out of the Caldera. We thought we would go a little closer to get some video in better light and no rain or lighting as there was the first morning. Just as we got within a mile or so she let lose with an eruption that shook the boat and you felt in your chest...Unfortunately our videoing ability is not so great and on a moving boat only makes it worse. It was quite amazing. Hope you all ejoy and check out our Web page of our family's Circumnavigation at Ohanakai.net... We are currently in Thailand gearing up for the Red Sea..

Mount Gunung Sinabung

Mount Sinabung (Indonesian: Gunung Sinabung) is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 25 miles from Lake Toba supervolcano, located at the coordinates 3°10'14.24"N 98°23'30.42"E (those listed to the right are incorrect, and instead link to the center of Gunung Leuser National Park). Many old lava flows are on its flanks and the last known eruption, before recent times, occurred in the year 1600. Solfataric activities (cracks where steam, gas, and lava are emitted) were last observed at the summit in 1912, other documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013.
The volcano erupted again on November 5, 2013, for the third time in as many months on the western Indonesian island of Sumatra, forcing hundreds of villagers to evacuate, officials said.
This volcano spewed a 7-km (4.3-mile) column of ash into the air, prompting authorities to impose a 3-km evacuation radius.
The military helped evacuate 1,293 people from four villages around the volcano, which is 88 km from the provincial capital, Medan. The number of evacuees was expected to rise.
No casualties were reported.
About 14,000 people were forced the evacuate when the volcano showed signs of activity in September. Sinabung is one of nearly 130 active volcanoes in the world's fourth-most populated country, which straddles the "Pacific Ring of Fire".
On November 11, 2013, a pyroclastic flow, a fast-moving avalanche of ash, lava fragments and air, was seen racing down the peak. Since then, the volcano has blasted out one to two ash explosions every day.Gunung Sinabung kuwi sawijining gunung ing dataran dhuwur Karo, Kabupatèn Karo, Sumatra Lor. Sinabung bebarengan karo Sibayak ing sacedhaké, minangka gunung geni aktif ing Sumatra Lor. Kanthi elevasi 2.460 meter, gunung iki dadi pucuk paling dhuwur ing Sumatra Lor. Koordinat pucuk gunung Sinabung yakuwi 3° 10 menit LU, 98° 23 menit BT.Gunung Sinabung (bahasa Karo: Deleng Sinabung) adalah gunung api di Dataran Tinggi Karo, Kabupaten Karo, Sumatera Utara, Indonesia. Sinabung bersama Gunung Sibayak di dekatnya adalah dua gunung berapi aktif di Sumatera Utara dan menjadi puncak tertinggi di provinsi itu. Ketinggian gunung ini adalah 2.460 meter.
Gunung ini tidak pernah tercatat meletus sejak tahun 1600[3] tetapi mendadak aktif kembali dengan meletus pada tahun 2010.
Most of Indonesian volcanism stems from the Sunda Arc, created by the subduction of the Indo-Australian Plate under the Eurasian Plate. This arc is bounded on the north-northwest by the Andaman Islands, a chain of basaltic volcanoes, and on the East by the Banda Arc, also created by subduction.[3]
Sinabung is an andesitic-dacitic stratovolcano with a total of four volcanic craters, only one being active.[4]
August 2010 eruption[edit]
Wikinews has related news: Mount Sinabung erupts in Sumatra, Indonesia
On 29 August 2010 (local time), the volcano experienced a minor eruption after several days of rumbling.[5] Ash spewed into the atmosphere up to 1.5 kilometres (0.93 mi) high and lava was seen overflowing the crater.[5] The volcano had been inactive for over four centuries, with the most recent eruption occurring in 1600.[5] 6,000 of the 30,000 villagers who had been evacuated returned to their homes on 31 August 2010.[6][7] The volcano was assigned to category "B" In Indonesia, as it was inactive for more than 400 years (volcanoes in category "A", must be monitored frequently).[8][9] The Indonesian Red Cross Society and the Health Ministry of Indonesia sent doctors and medicines to the region.[7] The National Disaster Management Agency provided face masks and food to assist the evacuees.El monte Sinabung (en indonesio: Gunung Sinabung) es un estratovolcán1 de 2.460 msnm formado en el Pleistoceno y situado al norte de la isla de Sumatra (Indonesia), en un área fundamentalmente agrícola. Se encuentra muy cerca de otro volcán, el Sibayak,2 y a 27 km de Brastaggi.3 Su última erupción fue en agosto de 2010, después de 400 años en calma.
El volcán se encuentra en el Arco de Sonda, una cadena volcánica que une el Cinturón Alpide con el Cinturón de Fuego del Pacífico. Tiene cuatro cráteres que se caracterizan por componerse de andesita y dacita, de los que sólo uno está activo.4

Convergent plate boundaries
Main article: Convergent boundary
Subduction zones are places where two plates, usually an oceanic plate and a continental plate, collide. In this case, the oceanic plate subducts, or submerges under the continental plate forming a deep ocean trench just offshore. In a process called flux melting, water released from the subducting plate lowers the melting temperature of the overlying mantle wedge, creating magma. This magma tends to be very viscous due to its high silica content, so often does not reach the surface and cools at depth. When it does reach the surface, a volcano is formed. Typical examples for this kind of volcano are Mount Etna and the volcanoes in the Pacific Ring of Fire.
"Hotspots"
Main article: Hotspot (geology)
"Hotspots" is the name given to volcanic provinces postulated to be formed by mantle plumes. These are postulated to comprise columns of hot material that rise from the core-mantle boundary. They are suggested to be hot, causing large-volume melting, and to be fixed in space. Because the tectonic plates move across them, each volcano becomes dormant after a while and a new volcano is then formed as the plate shifts over the postulated plume. The Hawaiian Islands have been suggested to have been formed in such a manner, as well as the Snake River Plain, with the Yellowstone Caldera being the part of the North American plate currently above the hot spot. This theory is currently under criticism, however.[1]
Volcanic features
Lakagigar fissure vent in Iceland, source of the major world climate alteration of 1783--84.
Skjaldbreiður, a shield volcano whose name means "broad shield"
The most common perception of a volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit. This describes just one of many types of volcano, and the features of volcanoes are much more complicated. The structure and behavior of volcanoes depends on a number of factors. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater, whereas others present landscape features such as massive plateaus. Vents that issue volcanic material (lava, which is what magma is called once it has esc\a vent of an igneous volcano.
Fissure vents
Main article: Fissure vent
Volcanic fissure vents are flat, linear cracks through which lava emerges.
Shield volcanoes
Main article: Shield volcano
Shield volcanoes, so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically. Since low-viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of uptions of mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. These can be relatively short-lived eruptions that produce a cone-shaped hill perhaps 30 to 400 meters high. Most cinder cones erupt only once. Cinder cones may form as flank vents on larger

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as 15 km (9.3 mi).
Stratovolcanoes are sometimes called "composite volcanoes" because of their composite layered structure built up from sequential outpourings of eruptive materials. They are among the most common types of volcanoes, in contrast to the less common shield volcanoes. Two famous stratovolcanoes are Krakatoa, best known for its catastrophic eruption in 1883 and Vesuvius, famous for its destruction of the towns Pompeii and Herculaneum in 79 CE. Both eruptions claimed thousands of lives. In modern times, Mount Saint Helens and Mount Pinatubo have erupted catastrophically.

Mount Sinabung (Indonesian: Gunung Sinabung) is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 25 miles from Lake Toba supervolcano, located at the coordinates 3°10'14.24"N 98°23'30.42"E (those listed to the right are incorrect, and instead link to the center of Gunung Leuser National Park). Many old lava flows are on its flanks and the last known eruption, before recent times, occurred in the year 1600. Solfataric activities (cracks where steam, gas, and lava are emitted) were last observed at the summit in 1912, other documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013.
The volcano erupted again on November 5, 2013, for the third time in as many months on the western Indonesian island of Sumatra, forcing hundreds of villagers to evacuate, officials said.
This volcano spewed a 7-km (4.3-mile) column of ash into the air, prompting authorities to impose a 3-km evacuation radius.
The military helped evacuate 1,293 people from four villages around the volcano, which is 88 km from the provincial capital, Medan. The number of evacuees was expected to rise.
No casualties were reported.
About 14,000 people were forced the evacuate when the volcano showed signs of activity in September. Sinabung is one of nearly 130 active volcanoes in the world's fourth-most populated country, which straddles the "Pacific Ring of Fire".
On November 11, 2013, a pyroclastic flow, a fast-moving avalanche of ash, lava fragments and air, was seen racing down the peak. Since then, the volcano has blasted out one to two ash explosions every day.Gunung Sinabung kuwi sawijining gunung ing dataran dhuwur Karo, Kabupatèn Karo, Sumatra Lor. Sinabung bebarengan karo Sibayak ing sacedhaké, minangka gunung geni aktif ing Sumatra Lor. Kanthi elevasi 2.460 meter, gunung iki dadi pucuk paling dhuwur ing Sumatra Lor. Koordinat pucuk gunung Sinabung yakuwi 3° 10 menit LU, 98° 23 menit BT.Gunung Sinabung (bahasa Karo: Deleng Sinabung) adalah gunung api di Dataran Tinggi Karo, Kabupaten Karo, Sumatera Utara, Indonesia. Sinabung bersama Gunung Sibayak di dekatnya adalah dua gunung berapi aktif di Sumatera Utara dan menjadi puncak tertinggi di provinsi itu. Ketinggian gunung ini adalah 2.460 meter.
Gunung ini tidak pernah tercatat meletus sejak tahun 1600[3] tetapi mendadak aktif kembali dengan meletus pada tahun 2010.
Most of Indonesian volcanism stems from the Sunda Arc, created by the subduction of the Indo-Australian Plate under the Eurasian Plate. This arc is bounded on the north-northwest by the Andaman Islands, a chain of basaltic volcanoes, and on the East by the Banda Arc, also created by subduction.[3]
Sinabung is an andesitic-dacitic stratovolcano with a total of four volcanic craters, only one being active.[4]
August 2010 eruption[edit]

On 29 August 2010 (local time), the volcano experienced a minor eruption after several days of rumbling.[5] Ash spewed into the atmosphere up to 1.5 kilometres (0.93 mi) high and lava was seen overflowing the crater.[5] The volcano had been inactive for over four centuries, with the most recent eruption occurring in 1600.[5] 6,000 of the 30,000 villagers who had been evacuated returned to their homes on 31 August 2010.[6][7] The volcano was assigned to category "B" In Indonesia, as it was inactive for more than 400 years (volcanoes in category "A", must be monitored frequently).[8][9] The Indonesian Red Cross Society and the Health Ministry of Indonesia sent doctors and medicines to the region.[7] The National Disaster Management Agency provided face masks and food to assist the evacuees.El monte Sinabung (en indonesio: Gunung Sinabung) es un estratovolcán1 de 2.460 msnm formado en el Pleistoceno y situado al norte de la isla de Sumatra (Indonesia), en un área fundamentalmente agrícola.

Convergent plate boundaries
Main article: Convergent boundary
Subduction zones are places where two plates, usually an oceanic plate and a continental plate, collide. In this case, the oceanic plate subducts, or submerges under the continental plate forming a deep ocean trench just offshore. In a process called flux melting, water released from the subducting plate lowers the melting temperature of the overlying mantle wedge, creating magma. This magma tends to be very viscous due to its high silica content, so often does not reach the surface and cools at depth. When it does reach the surface, a volcano is formed. Typical examples for this kind of volcano are Mount Etna and the volcanoes in the Pacific Ring of Fire.
"Hotspots"
Main article: Hotspot (geology)
"Hotspots" is the name given to volcanic provinces postulated to be formed by mantle plumes. These are postulated to comprise columns of hot material that rise from the core-mantle boundary. They are suggested to be hot, causing large-volume melting, and to be fixed in space. Because the tectonic plates move across them, each volcano becomes dormant after a while and a new volcano is then formed as the plate shifts over the postulated plume. The Hawaiian Islands have been suggested to have been formed in such a manner, as well as the Snake River Plain, with the Yellowstone Caldera being the part of the North American plate currently above the hot spot. This theory is currently under criticism, however.[1]
Volcanic features
Lakagigar fissure vent in Iceland, source of the major world climate alteration of 1783--84.
Skjaldbreiður, a shield volcano whose name means "broad shield"
The most common perception of a volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit. This describes just one of many types of volcano, and the features of volcanoes are much more complicated. The structure and behavior of volcanoes depends on a number of factors. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater, whereas others present landscape features such as massive plateaus. Vents that issue volcanic material (lava, which is what magma is called once it has esc\a vent of an igneous volcano.
Fissure vents
Main article: Fissure vent
Volcanic fissure vents are flat, linear cracks through which lava emerges.
Shield volcanoes
Main article: Shield volcano
Shield volcanoes, so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically. Since low-viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of uptions of mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. These can be relatively short-lived eruptions that produce a cone-shaped hill perhaps 30 to 400 meters high. Most cinder cones erupt only once. Cinder cones may form as flank vents on larger

This theory is currently under criticism, however.[1]

The most common perception of a volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit. This describes just one of many types of volcano, and the features of volcanoes are much more complicated. The structure and behavior of volcanoes depends on a number of factors. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater, whereas others present landscape features such as massive plateaus. Vents that issue volcanic material (lava, which is what magma is called once it has esc\a vent of an igneous volcano.
Fissure vents
Main article: Fissure vent
Volcanic fissure vents are flat, linear cracks through which lava emerges.
Shield volcanoes
Main article: Shield volcano
Shield volcanoes, so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically. Since low-viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of uptions of mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. These can be relatively short-lived eruptions that produce a cone-shaped hill perhaps 30 to 400 meters high. Most cinder cones erupt only once. Cinder cones may form as flank vents on larger
