Article 1: Aleutian Range edit
I started to look for plagiarism by going to the one reference that was already cited, but it linked me to a locked government website. I added a citation for the first few sentences, and revised it to address possible plagiarism.
My contribution
I worked on a stub article
Added links to wikipedia pages to "7.9 magnate," "earthquake," "volcanic eruptions," and tsunamis."
- Mount Okmok (1,073 m), Fox Islands
Volcanic Eruptions edit
Two volcanoes in the Eastern Aleutian Islands erupted during the summer of 2008. On July 12, 2008, Mount Okmok erupted, and it continued to erupt for a month. A giant, rapidly moving ash and gas cloud shot up to a height of 15,240 m as a result of this eruption. [1] Mount Kasatochi was home to the other eruption, which occurred on August 7th and 8th. This eruption also sent up a gas cloud about 15,000 high. Together, these two power volcanic eruptions deposited emissions of trace gases an aerosols into the atmosphere. These emissions formed a sulfate aerosol layer that totaled a transfer of 1.6 Tg SO2 into the stratosphere and disturbed flights over this area for a short period following the eruptions. [2]
Earthquakes edit
In June of 2014, a 7.9 magnitude earthquake struck the Aleutian Islands. The epicenter was below the earth's surface at a depth of 107 km.[3] The quake was caused by oblique normal faulting, and it occurred at a subduction zone. Here, the convergent boundary consists of the Pacific plate subducting underneath the North American plate, and this occurs at the speed of about 59 mm/year.[4] Although it was a powerful earthquake, no volcanic eruptions or tsunamis resulted, which is an unusual outcome since the area is seismically active.

Article 2: Volcanology of Indonesia edit
I started off by reading through the article and correcting grammatical errors and fixing sentence structures. Then, I began to look for plagiarism by google searching sentences in the article that were not directly followed by citations, and for the most everything seemed okay. Next, I saw that there were two sentences that said citation needed at the end, and I found a citation for one of them and added more details to the sentence. The other sentence seemed very opinionated, so I deleted the second part, and then found a source that I used to add information on the original topic.
I added information to the introduction such as the number of eruptions within historical times, details about the Sunda Arc, and details about the plate boundary that causes most indonesian volcanoes.
I then made the "volcanic eruptions" headline for the second part and added information about Mount Tambora, Krakatoa, and Mount Merapi.
I also made the "preparation" headline and added info about the Volcanological Survey of Indonesia and some examples of how they've aided in preparation.
I added links to wikipedia pages for "Sunda Arc," "Volcanic Explosivity Index," "Galunggung," "Makian," "Volcanological Survey of Indonesia," and "Lampung."
Article 3: 2011 Lake Champlain and Richelieu River floods edit
I started off by looking for plagiarism. I copy and paste different sentences into google to see if any of them were directly copied from other places, but that was not the case of any of the sentences in this article. I also opened up the reference articles to search for plagiarism and found nothing suspicious. A couple of the reference articles were in French so I don't really know if or how much might have been copied from those articles. I then read through the article and corrected grammatical errors.
I added information to the introduction about the causes of the flooding, the length of time that the lake was at flood stage, the record flood level, the state of emergency declaration in Vermont, and the contaminated water supplies in Quebec. My information came from the three sources that I cited which included two government websites and a review from the Lake Champlain Basin Program.
I added added links to wikipedia pages for "snowfall," "snowmelt," "flood stage," and "state of emergency."
Maggieelize Feedback: 2011 Lake Champlain and Richelieu River Floods edit
It would help if you would quote the exact phrases you added to the article so it would be easier to identify what was changed. Also why was there record snowfall during that winter? Did any sources have theories on why there might have been so much snow (climate change, etc.)? Overall, it seems like you made a good contribution though!
