Slide 11 Resources. Slide 12 What is a volcano? A volcano is a mountain that extends down to a pool of magma between the crust and mantle.It is basically a hole in the Earth from which magma can Erupt!!! How is a Volcano Formed? Volcanoes are formed when magma in the Earth's upper mantle works its way to a surface. At the surface it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt it will get bigger and bigger. Why Does a Volcano Erupt? The Earth’s crust is made up of huge slabs called plates. It fits together like a puzzle. These plates sometimes move.The friction causes earthquakes and volcanic damages near the edges of the plates.The theory that explains this process is called plate tectonics. What is the Ring of Fire? The Pacific ring of fire has a lot of volcanic eruptions and earthquakes too. The Pacific ring of fire is located in Hawaii. What is Magma and Lava? Magma is made up of molten rock and it is found in the Earth's crust. Lava is magma that reaches the surface of Earth through a volcano opening at the top. When magma erupts out of the volcano, it is called lava. It is made of rock and gases and it is between the Earth’s crust and the mantle. When lava comes out of the volcano and its cools off it turns into molten rock. What is the Largest Volcano? The world’s largest, active volcano is Mauna Loa in Hawaii. Mauna Loa is 13,677 feet above sea level. Mauna Loa is taller than Mount Everest!

Volcanic Eruption Impacts Student Worksheet
Volcanic Eruption Impacts Student Worksheet Explosive and Effusive Volcanoes The type of volcanic eruption is largely determined by magma composition. Flux-mediated melting at subduction zones creates a felsic magma with high levels of carbon dioxide and water. These dissolved gases explode during eruption. Effusive volcanoes have a hotter, more mafic magma with lower levels of dissolved gas, allowing them to erupt more calmly (effusive eruption). Sinabung (Indonesia) Mount Sinabung is a stratovolcano located 40 km from the Lake Toba supervolcano in North Sumatra. It lies along the Sunda Arc, where the Indo-Australian plate subducts beneath the Sunda and Burma plates. After 1200 years of dormancy, Sinabung began erupting intermittently in 2010. Major eruptions have occurred regularly since November 2013. In November and December 2015, ash plumes reached 6 – 11 km in height on multiple occasions. Pyroclastic flows and ashfall blanketed the region in January 2014 and lava flows travelled down the south flank, advancing 2.5 km by April 2014. Pyroclastic flows in February 2014 killed 17 people in a town 3 km from the vent. In June 2015, ash falls affected areas 10 – 15 km from the summit on many occasions. A lahar in May 2016, caused fatalities in a village 20 km from Sinabung. Pyroclastic flows occurred frequently throughout 2016 and 2017 Eruption of Sinabung 6 October 2016 Major eruptions occurred in 2018 and 2019. In (Y Ginsu, public domain) February 2018, an eruption destroyed a lava dome of 1.6 million cubic metres. At least 10 pyroclastic flows extended up to 4.9 km and an ash plume rose more than 16 km in altitude.

Unconventional Structures: Toroidal Plume
31 Architecture in an Expanded Field, from Interiors to Landscapes Unconventional_Structures: Toroidal Plume JORGE ADAN ITUARTE-ARREOLA RYAN LEE THOMAS Texas Tech University United States Army National Guard The ever-shifting surface of the earth creates a plethora of effects on territories, climate, and territorial ecosystems. Of these effects, no hemispheric region appears as catastrophi- cally consistent in terms of natural disasters, than that of the Asia-Pacific. Geographically speaking, the country of Indonesia happens to receive the blunt of Earth’s natural forces, given that it resides in the belt of shifting tectonic plates known as the Ring of Fire, whose proximal circumstances make it highly susceptible to seismic and volcanic activity. To fully understand the risk of these circumstances, and their scope in terms of the ecologies they affect, analysis was enacted through critical cartography. Part of this effort involved instructing local people on how to map their region using Open Source Data, as a means of progressive local agency. This locally-revised data served as a mechanism to understand how people react to natural disas- ters; how they travel, urbanize, operate, and evacuate. The area of study consisted of Mount Sinabung, a recently active stratovolcano, and its neighboring territories in North Sumatra, Indonesia. Through exploration and analysis based on the volcano’s risk and effects, we sought to resolve the most ailing issue this region is succumb to. Ash. Airborne ash proved to be the largest concern in regards to the volcano, causing respiratory damages, infections, and death to the people living there. Volcanic ash has proven beneficial for the surrounding agriculture, in the soil, and can also be utilized as a binding agent in concrete production.

Rokhis Khomarudin Remote Sensing Applications Center, Indonesian National Institute of Aeronautics and Space (LAPAN) e-mail: [email protected]/[email protected] Received: 26 February 2015; Revised: 7 April 2015; Approved: 11 May 2015 Abstract. The position of Indonesia as part of a "ring of fire" bringing the consequence that the life of the nation and the state will also be influenced by volcanism. Therefore, it is necessary to map rapidly the affected areas of a volcano eruption. Objective of the research is to detect the affected areas of Mount Sinabung eruption recently in North Sumatera by using optical images Landsat 8 Operational Land Imager (OLI). A pair of Landsat 8 images in 2013 and 2014, period before and after eruption, was used to analysis the reflectance change from that period. Affected areas of eruption was separated based on threshold value of reflectance change. The research showed that the affected areas of Mount Sinabung eruption can be detected and separated by using Landsat 8 OLI images based on the change of reflectance value band 4, 5 and NDVI. Band 5 showed the highest values of decreasing and band 4 showed the highest values of increasing. Compared with another uses of single band, the combination of both bands (NDVI) give the best result for detecting the affected areas of volcanic eruption.

International Journal of Architecture and Urbanism Vol. 03, No. 02, 2019 | 160 – 168 The Design Museum of Mount Sinabung with Neo- Vernacular Architecture Approach Wahyuni Zahrah 1*, Ade Syahputra Astono1 1Architecture Department, Faculty of Engineering, Universitas Sumatera Utara, Medan, Indonesia. Abstract. Mount Sinabung is a volcano on the plateau of Karo Regency, North Sumatra, Indonesia. Mount Sinabung suddenly erupted in 2010. The last eruption of the volcano occurred since February 19, 2018, and until now become an attraction to find out more about volcanic disasters. Museum Mount Sinabung is present to provide the means for education, dissemination of information in the aspect of the volcano and geological disaster with recreative and educative of nature. The problem raised was "How to design a volcano museum using the neo-vernacular architectural approach?". By applying one flow that develops in this post-modern era to revive memories of a semi-historical culture, representational, plural and eclectic cultural Agenda on to evoke the Design of Museum Mount SinabungIn the application of the neo-vernacular architectural approach to the building of the Museum, the principle of building the Siwaluh Jabu is restored, physically and non-physically.By using the qualitative method of designing the Museum, it was designed because it was rational and planned systematically with the selected location. So, the Museum is conceptualized with a flexible gallery that can be used as a shelter for refugees. Thus, it is expected that the Museum can be a recreational-educational facility and as a means of supporting disaster mitigation. Keyword: architecture, educational, museum, mount, recreational. 1.

After being dormant for about 400 years, Sinabung volcano erupted on the 29th of August, 2010 and most recently on the 1st of November, 2016. We measured the deformation of Sinabung volcano using Advanced Land Observing Satellite/Phased Array type L-band Synthetic Aperture Radar (ALOS/PALSAR) interferometric synthetic aperture radar (InSAR) images acquired from February 2007 to January 2011. Based on multi-temporal InSAR processing, we mapped the ground surface deformation before, during, and after the 2010 eruption with time-series InSAR technique. During the 3 years before the 2010 eruption, the volcano inflated at an average rate of ~1.7 cm/yr with a markedly higher rate of 6.6 cm/yr during the 6 months prior to the 2010 eruption. The inflation was constrained to the top of the volcano. From the 2010 eruption to January 2011, the volcano subsided by approximately 3 cm (~6 cm/yr). We interpreted that the inflation was due to magma accumulation in a shallow reservoir beneath Sinabung.

The August 2010 Phreatic Eruption of Mount Sinabung, North Sumatra
Indonesian Journal of Geology, Vol. 8 No. 1 March 2013: 55-61 The August 2010 Phreatic Eruption of Mount Sinabung, North Sumatra Letusan Freatik Gunungapi Sinabung Agustus 2010, Sumatra Utara I. S. Sutawidjaja, O. Prambada and D. A. Siregar Geological Agency Jln. Diponegoro No. 57, Bandung, 40122 Abstract Mount Sinabung, located in Karo Regency, North Sumatra Province, is a strato volcano having four active craters. Since its latest eruption about 1,200 year ago, a phreatic eruption occurred on August th27, 2010. The eruption took place in Crater-I, which was initiated by a greyish white plume and then followed by black plumes as high as 2000 m above the crater. Altered rock fragments and ash were erupted during this event. The altered rocks show a development of argillic alterations which was formed in the hydrothermal system in depth. The alteration zone is formed along the northeast-southwest and northwest-southeast trend across the three craters. All of the craters are actively discharging solfata ric gases, of which sulphur deposits are resulted, and they have been quarried by the local people. The age of the latest magmatic eruption was dated by 14C method from the charcoal sample found in the pyroclastic flow deposits near Bekerah Village. Keywords: Mount Sinabung, phreatic eruption, argillic alteration, 14C method Sari Sinabung adalah gunung api strato yang terletak di Kabupaten Karo, Sumatra Utara, dan mempu- nyai empat kawah aktif.
