are cinder cone volcanoes dangerous?
316029
The primary danger from cinder cone volcanoes is lava flows. Once the bulk of the gasses have been released, the eruptions begin to produce large flows of runny lava. These flows typically emerge from either fissures at the base of the volcano or breaches of the crater wall.

Although known for quiet eruptions of lava that rarely endanger lives, Kilauea Volcano on the Island of Hawai'i has also produced devastating and deadly explosive eruptions in the past.

-The greatest danger of living near any type of volcano that erupts magma with high content of silica, are the infamous Piroplastic flows, scorching avalanches of red-hot material, pulverized rocks and gas that would advance in all directions from the respirator or that produces them, roasting and burying with ...

Composite volcanoes are tall, steep cones that produce explosive eruptions. Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Gaseous emissions from an erupting volcano can suffocate, poison, or induce health problems among humans and animals. ... Lastly, large amounts of volcanic ash repeatedly ejected into the atmosphere can disrupt the weather, reduce visibility, and cause harmful effects upon air travel.

Volcanoes are classified by the eruption type and by the volcanic cone shape. ... The three cone shapes are cinder cones, shield cones, and composite cones or stratovolcanoes. The six eruption types are in order from least explosive to the most explosive; Icelandic, Hawaiian, Strombolian , Vulcanian , Pelean, and Plinian.

Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.

But a caldera collapse can cause a sudden release of gas, which can explode up and outward, as seen in the big eruptions in recorded history. And the biggest danger is simply that the mountain is falling in on itself, which can trigger huge landslides or engulf entire regions.

Volcanic activity and volcanic eruption is usually triggered by alterations of tectonic plates, resulting in landslides or earthquakes. Volcanic eruptions can be extremely damaging to the environment, particularly because of a number of toxic gases possibly present in pyroclastic material.

When a volcano erupts it throws out a lot of ash. At short notice this ash can be very harmful to the environment, but on the long term the ash layer, which contains many useful minerals, will be converted to a very fertile soil. Nearly everywhere volcanoes are located people use the rich soil for farming.

Mount Vesuvius is considered to be one of the most dangerous volcanoes in the world because of its proximity to the city of Naples and the surrounding towns on the nearby slopes. The volcano is classed as a complex stratovolcano because its eruptions typically involve explosive eruptions as well as pyroclastic flows.

Eruptions at shield volcanoes are only explosive if water somehow gets into the vent , otherwise they are characterized by low-explosivity fountaining that forms cinder cones and spatter cones at the vent, however, 90% of the volcano is lava rather than pyroclastic material.

It's been 40 years since Mount St. Helens famously roared to life, sending ash and gas 15 miles high, flattening 135 square miles of forest, and killing 57 people in the country's deadliest eruption. Today, the volcano is still one of the most dangerous in the United States, and the most active of the Cascade Range.

Answer: No, volcanoes generally are found along the zone of collision of pales or along some fault line. Explanation: An estimated 6% of the earthquakes that active are those that are found on the active plate margins and thus are highly dangerous.

Cinder cones As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings.

The main parts of a volcano include the magma chamber, conduits, vents, craters and slopes. There are three types of volcanoes: cinder cones, stratovolcanoes and shield volcanoes.
