Q. What type of volcano has quiet and explosive eruptions?
Shield volcanoes
Q. What determines if a volcano is quiet or explosive?
The amount of water vapor and other gases present is one factor that determines whether a volcanic eruption will be quiet or explosive.

Q. What determines the type of volcano that forms?
When magma erupts at the surface, as lava, it can form different types of volcanoes depending on the viscosity, or stickiness, of the magma, the amount of gas in the magma, the composition of the magma and the way in which the magma reached the surface.
Q. Is a type of volcano that is formed from quiet eruptions?
A quiet eruption of low-viscosity lava produces a wide, flat volcano called a shield volcano. If an eruption is entirely ash and cinders, the result will be a small, steep-sided volcano called a cinder cone.
Q. Which type of volcano would be the least explosive?
Q. What would a non explosive eruption look like?
Non-explosive type eruptions mostly produce various types of lava, such as a’a, pāhoehoe and pillow lavas. Some signs that a volcano may soon erupt include earthquakes, surface bulging, gases emitted as well as other changes that can be monitored by scientists.
Q. What is phreatic or hydrothermal eruption?
Hydrothermal eruptions pulverise surrounding rocks and can produce ash, but do not include magma. These are typically very small eruptions. Phreatic eruption. An eruption driven by the heat from magma interacting with water. The water can be from groundwater, hydrothermal systems, surface runoff, a lake or the sea.
Q. What volcano is an example of phreatic eruption?
Krakatoa
Q. Is Taal Volcano Plinian?
Taal Volcano, Philippines, 1965. The most powerful eruptions are called “plinian” and involve the explosive ejection of relatively viscous lava. Large plinian eruptions–such as during 18 May 1980 at Mount St. Fast-moving deadly pyroclastic flows (“nuées ardentes”) are also commonly associated with plinian eruptions.
Q. Is Taal phreatic?
In January last year, Taal Volcano spewed ash in a phreatic eruption which forced thousands of residents to evacuate. The ash fall from the phreatic eruption also reached as far as Metro Manila and other nearby provinces.
Q. Is the whole Taal Volcano Island a PDZ?
PHIVOLCS raised the Alert Level to 2 (on a scale of 0-5) and reminded the public that the entire Volcano Island (the main cone of Taal) is in a Permanent Danger Zone (PDZ).
Q. Is Taal Volcano Active or inactive?
Taal volcano with its lake-filled 15×20 km wide Talisay (Taal) caldera is a beautiful caldera volcano, but also one of the most active and dangerous volcanoes of the Philippines.
Q. How long is Taal volcano inactive?
Although it is classified as an active volcano, it hasn’t erupted in 43 years or since 1977. The volcano consists of multiple stratovolcanoes and craters. Since 1572, it has recorded 34 eruptions. The eruptions were not all similar.
