Volcano eruption

Some volcanic eruptions are explosive and others are not. The explosivity of an eruption depends on the composition of the magma. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano Kīlauea Volcano began erupting on December 20, 2020, at about 9:30 p.m. HST in Halema'uma'u crater Mayon volcano photos Mayon on Luzon Island, towering above Legazpi city is famous for being one of the most perfectly symmetrical stratovolcanoes in the world.

  2. Strombolian eruptions are a type of volcanic eruption named after the volcano Stromboli, which has been erupting nearly continuously for centuries. Strombolian eruptions are driven by the bursting of gas bubbles within the magma. These gas bubbles within the magma accumulate and coalesce into large bubbles, called gas slugs
  3. A volcano is an opening on the surface of a planet or moon that allows material warmer than its surroundings to escape from its interior. When this material escapes, it causes an eruption. An eruption can be explosive, sending material high into the sky. Or it can be calmer, with gentle flows of material. This photograph shows an eruption of.
  4. The Mount Pinatubo eruption was the second largest volcanic eruption of the 20 th century. On 15 June, the volcano erupted, creating an ash cloud that rose 35km into the air. The eruption created massive avalanches of pyroclastic flows and ejected nearly 20 million tons of SO 2 into the stratosphere, causing global temperatures to plummet.
  5. The eruption of Novarupta on June 6 - 8, 1912 was the largest volcanic eruption in recent history in the United States. Novarupta spewed 13 cubic kilometers (3.1 cubic miles) of magma, which turned into 30 cubic kilometers (7.2 cu mi) of ash that blanketed the nearby area. The ash from Novarupta was launched over 100,000 feet (32 kilometers.
