What type of volcano is non-explosive and explosive?
Shield volcanoes
Shield volcanoes are built by many layers over time and the layers are usually of very similar composition. The low viscosity also means that shield eruptions are non-explosive. Eruptions tend to be mild in comparison to other volcanoes, but lava flows can destroy property and vegetation.
Where are non-explosive volcanoes?
B. Vast areas of the Earth’s surface, including much of the sea floor and the Northwestern United States, are covered with lava form nonexplosive eruptions. A. While explosive eruptions are much rarer than non-explosive eruptions, the effects can be incredibly destructive.

Is isarog volcano active or inactive?
Mt Isarog is a large, isolated peak in Camarines Sur Province, on the Camarines Peninsula in southeastern Luzon. The mountain is a dormant volcano that rises to 1,976 m.
Is Parker volcano active?
Mount Mélébingóy, formerly called by colonizers as Parker, is potentially active stratovolcano on Mindanao island in the Philippines (6°06.8′ N, 124°53.5′ E).
What volcanic eruption is more explosive than their strombolian?
Vulcanian eruptions
Vulcanian eruptions are far more explosive than Strombolian eruptions, and can blast tephra and gas to a height of 5 to 10 km. The explosiveness is related to a build-up of pressure as the higher viscosity of intermediate silica content lava restricts the escape of gas.
What is the Paricutin eruption?
Paricutin provided such an opportunity. The eruption that created Paricutin began in 1943 and continued to 1952. Most of the explosive activity was during the first year of the eruption when the cone grew to 1,100 feet (336 m). The cone continued to grow for another 8 years but added only another 290 feet (88 m).
Where is the closest city to the Parícutin volcano?
location of Parícutin in Mexico. Parícutin (or Volcán de Parícutin, also accented Paricutín) is a cinder cone volcano located in the Mexican state of Michoacán, near the city of Uruapan and about 322 kilometers (200 mi) west of Mexico City.
What is the difference between pyrotechnic and explosive?
A pyrotechnic substance is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas or smoke or a combination of these as the result of non-detonative self-sustaining exothermic chemical reactions. An explosive article is an article containing one or more explosive substances.
What are the characteristics of explosive materials?
EXPLOSIVES DEFINITIONS 1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.
