**Summary:**
Suwanose-jima is a most frequently active volcano in Tokyo. The first erupt is in 1600, and scientist said that this is not the correct time. The largest historical eruption took place in 1813-14. At the end of the eruption the summit of On-take collapsed forming a large debris avalanche and creating the horseshoe-shaped Sakuchi caldera, which extends to the eastern coast, and make a shape like now.

__//1. Question: Is Suwanose-jima a shield volcano, a cinder cone, or a composite volcano?//__ - //Answer:// Suwanose-jima is a type of stratovolcano. In the other words, it is a composite volcano.

//__2. Question: What kind of lava is in a stratovolcano?__// //- Answer:// The type of lava in a stratovolcano is Felsic that means that it is very sticky and very explosive and fierce.

//__3. Question: What kind of lava dose Suwanose-jima have?__// //- Answer:// Aerosol, Cloud and Wind Lidars for atmospheric remote observations. Suwanose-jima is startovolcano, so the lava of it is sticky, and it has high viscosity.

//__4. Question: What type of eruptions does my volcano produce?__// - Answer: Strombolian-type eruption is the Suwanose-jima produced. Strombolian is a type of low level eruptions, which named from the volcano Italian Stromboli. This type of eruption ejects cinder, lapilli, and lava bombs to altitudes of tens to hundereds of meters. They are small to medium in volume, with sporadic violence.

//__5. Question: What the type of tectonic activity is making this volcano?__// //- Answer:// Japan has over 100 active volcanoes, more than almost any other country and accounts alone for about 10 % of all active volcanoes in the world. This is because Japan is located at the junction of 4 tectonic plates, which are the pacific, Philippine, Eurasian and North American plates. Also, the volcanoes are mainly located on 5 subduction zone related volcanic arcs where the Pacific Plate descends under the North American Plate along the Kuril Trench and the Japan Trench and underneath the Philippine Sea Plate along the lzu-Bonin Trench. The Philippine Plate subducts beneath the Eurasian Plate, anf forming the Ryukyu Trench, which is where Suwanose-jima located.// - Other Information for the tectonic activity of Japanese volcanoes:
 * Ryukyu Arc and Southwest Honshu Arcs in the south (Philippine plate subducting beneath between the Eurasian Plate)
 * Izu-Bonin-Mariana Arc (subduction of Pacific plate beneath Philippine plate)
 * Northeast Honshu and Kurile Arc in the north (subduction of Pacific plate beneath the N-American plate)

//__6. Question: Are there any of the following landforms nearby: calderas, lave plateaus, necks, sills, or dikes? Does Suwanose-jima has any significant geothermal activity near it?__// //- Answer:// I can;t find any special landforms and significant geothermal activity near Suwanose-jima.
