= Gas Slug = A gas slug is a conglomerate of high pressure gas bubbles that forms within certain volcanoes, the agitation of which is a driving factor in Strombolian eruptions. They start out as small bubbles of gas inside of volcanic magma. These accumulate into one large bubble, which starts to rise through the lava plume. Gas slugs also consist of many chemical properties that assist scientists in monitoring volcanic eruptions.

Chemistry
Volcanic eruptions consist of mostly water vapor gases, with sulfur dioxide and carbon dioxide playing a huge part in gas release as well. Volcanic gases also rely on the composition of magma in the chamber of the volcano and gas separation processes before the point of eruption.

Taylor bubbles, named after G. I. Taylor, refer to elongated gas bubbles in a liquid flow of a system. Taylor bubbles are distinctly "bullet shaped" and are involved in fluid dynamics. Within volcanic activity, magma rises in the volcanic chamber, slowing the movement of gas particles (H2O, SO2, CO2) and allowing for them to separate. As a result, this creates Taylor bubbles, which play a big part in Strombolian eruptions.

Formation
Once the accumulated slug reaches the top of the column and comes in contact with air, it bursts with a loud pop because of the lower air pressure, throwing magma into the air in the typical lava volcanic arc of a Strombolian eruption. This type of eruption is episodic, non-damaging to its source vent, and one of the slowest forms of activity, with the ability to sustain itself for thousands of years. Recent research also suggests that they can form as deep as 3 km under the surface.

Monitoring/Hazards and Impacts
Gas slugs help volcanologists monitor Strombolian eruptions with the help of overpressure stimulation, which occurs when too much pressure grows from the uprising of magmatic material. Seismic and infrasonic signals also contribute to the monitoring of these specific eruptions around the world with the help of gas slugs.

Volcanic activity can pose a threat to the environment and its surroundings, humans, and animals as well. Gas slugs lead to more outbursts of magma and lava from the volcano, leading to pyroclastic flows. These currents from the flows are very dense due to their solid and gaseous properties, allowing them to seep into the environment, harming agriculture and any other living aspects.

Notes:
Lead section with a concise and accurate single sentence:

-Defining the actual term.

-Everything in the intro paragraph encapsulates everything forward in the article; main ideas presented

^Wait on synopsis for later, once everything comes together

At least 2 paragraphs of new text:

-Organize w/ subheaders!

-Thoroughly cited and wiki linked

Draft text cites the two references provided:

-Second citation

Citations are relevant and appropriate to the statements where they are cited

-Conglomerate- rocks, general (change?)

-Clear subject, no "they", "it"

accumulates into one large bubble

Add more info from second citation - Can't be too specific, general view on topic

-Look at intro and conclusion paragraph - Review on vertical gas-liquid slug flow(Taylor bubbles!)

-Add info about pyroclastic flows?

-Physics section

-Chemistry section

Evaluating content:

The article starts off with a clear definition of gas slug and the content remains clear and concise throughout the entirety of the article yet it feels like the article needs more information. Some of the background knowledge does distract me as I did not know what it meant but it helped me by clicking on the links provided. Most of the information is up to date. The article could also include a real world example of a gas slug that occurred recently to give the audience more information.

Evaluating tone:

The article remains neutral and without bias which shows information is not leaning towards one side. Communicates effectively toward the audience, providing scientific knowledge.

Evaluating sources:

Article includes sources for each paragraph and are reliable and up to date. All of the links work, except some of the illustrations aren't shown for the first source regarding volcanoes. The sources support and back up the claims made in the article.

Evaluating talk page:

A talk page has not been started yet on the article. The article is rated as stub and is apart of the WikiProject volcanoes as well.
