1. eruptions

   Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs, and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions: Magmatic eruptions are the most well-observed type of eruption. They involve the decompression of gas within magma that propels it forward. Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic eruptions, where no fresh magma reaches the surface.Within these wide-defining eruptive types are several subtypes. The weakest are Hawaiian and submarine, then Strombolian, followed by Vulcanian and Surtseyan. The stronger eruptive types are Pelean eruptions, followed by Plinian eruptions; the strongest eruptions are called Ultra-Plinian. Subglacial and phreatic eruptions are defined by their eruptive mechanism, and vary in strength. An important measure of eruptive strength is the Volcanic Explosivity Index an order-of-magnitude scale, ranging from 0 to 8, that often correlates to eruptive types As of December 2022, the Smithsonian Institution's Global Volcanism Program database of volcanic eruptions in the Holocene Epoch (the last 11,700 years) lists 9,901 confirmed eruptions from 859 volcanoes. The database also lists 1,113 uncertain eruptions and 168 discredited eruptions for the same time interval.

Examples of eruptions in a Sentence

1. John Foster:

   The constant activity on the surface of the Sun is punctuated by violent outbursts powered the Sun’s strong magnetic field. Solar flares emit bursts of X-rays that travel outward at the speed of light, coronal mass ejections( CMEs) are giant eruptions of hot gasses from the Sun’s outer atmosphere. As this blast wave of solar material( plasma) streams towards the planets at 1000 km/sec, it sweeps up the magnetic field in its path, creating a magnetized shockwave of the type that struck Earth’s magnetic field on October 8, 2013.

2. Justin Wang:

   It's hard to imagine something more hostile to life than an ultra-acidic volcanic lake with frequent eruptions, the low biodiversity coupled with numerous adaptations and metabolisms in our sample suggests the lake hosts highly specialized microbes for this kind of environment.

3. Justin Wang:

   When I went to Costa Rica Poás volcano, Costa Rica Poás volcano was after over a year of magmatic eruptions and only a month after the lake reformed and it was deemed safe enough to return to the crater lake's surface, the lake itself is roiling and dynamic. As you get even closer, you can smell the strong stench of sulfur, which has remained on the clothes I was wearing to this day. Even worse is the smell of hydrochloric acid, which tastes sour in the air and stings the eyes.

4. Paul Renne:

   We are suggesting that it is very likely that a lot of the gases that come from magma systems precede eruptions; they dont necessarily correlate with eruptions.

5. Steve Brusatte:

   As Pangea split there were huge volcanic eruptions, about 200 million years ago, and these plunged the world into chaos: environmental destruction and rapid climate swings, the big amphibians couldn't cope well and many species went extinct, but dinosaurs and mammals made it through.
