Hereof, is Mount Pinatubo a shield volcano?
Mt. Pinatubo is a composite volcano because of its broad base and because the slopes of the volcano get steeper the closer you get to the summit. Composite volcanoes are made with a combination of pyroclastic material and lava. Composite volcanoes are also referred to as stratovolcanoes.
Furthermore, why Mount Pinatubo is an active volcano? The Mt Pinatubo eruption of 1991 was the second largest eruption of the 20th century. Mount Pinatubo Volcano had been dormant for 400 years. Before 1991 Pinatubo was an inconspicuous volcano which was known to be active in the past 1000 years and was the site of a failed geothermal development.

What type of eruption was Pinatubo 1991?
The second-largest volcanic eruption of this century, and by far the largest eruption to affect a densely populated area, occurred at Mount Pinatubo in the Philippines on June 15, 1991. The eruption produced high-speed avalanches of hot ash and gas, giant mudflows, and a cloud of volcanic ash hundreds of miles across.
Which volcano is most dangerous?
In the wake of its recent fiery rampage, it's perhaps no surprise that Kīlauea in Hawaii tops the list as the most dangerous volcano in the U.S., according to newly released rankings from the U.S. Geological Survey. Washington's Mount St. Helens and Mount Rainier round out the top three slots.What type of volcano is most dangerous?
Not surprisingly, supervolcanoes are the most dangerous type of volcano. Supervolcanoes are a fairly new idea in volcanology. The exact cause of supervolcano eruptions is still debated, however, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion.What kind of lava builds steep cones?
Some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.Which volcano is most likely to erupt?

20 Years After Pinatubo: How Volcanoes Could Alter Climate. Then, on June 15, the volcano blew its top in the second largest volcanic eruption of this century. These volcanoes are not metronomes; they tend to vary on a theme. Though we don't expect to see one again in our lifetime, it's not impossible."Why is the stratovolcano the most dangerous?
This lava plugs up the plumbing in stratovolcanoes, allowing them to build up tremendous amounts of pressure. Of all the volcanoes on Earth, stratovolcanoes are the most dangerous. They can erupt with little warning, releasing enormous amounts of material. And they don't always erupt nicely from their tops.How many days does a volcano take to erupt?
Historic eruptions have lasted less than a day to thousands of years. In 1977, the lava lake at Nyiragongo drained in less than one hour. In contrast, Stromboli has had a low-level of activity since 450 BC (about 2,400 years). The median duration of historic eruptions is 7 weeks.How many died in Mount Pinatubo eruption?

Mauna LoaHow did Mount Pinatubo effect the environment?
The eruption of Mount Pinatubo caused significant damage to the economy and infrastructure of surrounding cities. Mount Pinatubo ejected roughly ten billion tons of magma onto the surrounding landscape and millions of tons of sulfur dioxide gas into the atmosphere, spreading an ash cloud over much of the earth.Can you swim in Mt Pinatubo crater lake?
Pinatubo crater not to swim in the lake despite its tempting clear-blue waters. Kayaking or aqua cycling is also not allowed on the lake. A tourism official cited an advisory from the Philippine Institute of Volcanology and Seismology which states that the water on the lake contains toxic substances such as sulfur.Is Mount Pinatubo convergent or divergent?
Mount Pinatubo is on a boundary between the Continental Eurasian and Oceanic Philippine plate. The Oceanic Philippine plate is being pushed under the lighter Continental Eurasian plate. The volcano isn't completely even with the two plates, so when the Oceanic plate is submerged it is melted and forced away as magma.Is Pinatubo still active?
Pinatubo has been relatively quiet since the 1991-1992 eruption, but it is still active. It remains to be determined whether or not more explosions at the volcano are likely during the current eruptive period.What kind of lava does a stratovolcano have?
A stratovolcano is a tall, conical volcano composed of one layer of hardened lava, tephra, and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions. The lava that flows from them is highly viscous, and cools and hardens before spreading very far.How many volcanoes are in Bicol Region?
