This was a good article that I really enjoyed reading. The first thought that I had was that it must be so stressful for the scientists to find out when the volcano will erupt because so many people are relying on them to live or to die. Also, I find all the tools that they use really cool. For example, the Seismometers, that track the rise of magma and its movement along fissures. Next, it is also interesting that all volcanos are different. They are kind of like people and animals. In conclusion, I found this article really interesting and fun to read because of the detailed descriptions and good writing.

This was a great article. It was really interesting to think about how we can find out when volcanoes are going to erupt. This is very useful because volcanoes are destructive and has caused up to 71,000 deaths at a time. I liked the thought of tracking the volcano by using the carbon dioxide emitted from it beforehand. It seems like a reliable way to track it. I wasn't quite clear on the meaning of seismic, so I looked it up, and it actually means the vibration of the earth and the crust of the earth. However, we still have a lot of work to do in this aspect. This article says that the best way to judge a volcano's eruption is to combine all the methods, but that is a waste of time, energy, and money. I think that we should observe every eruption and either come up with or choose a method that works consistently. I really enjoyed learning about all the tools scientists use to predict eruptions and how they do it. When reading the article, they mentioned Pinatubo. The eruption of Pinatubo in the Phillipines was the second largest one of the century and thousands of lives were saved because of the scientists' warnings and the warning of a huge cloud of ash. I do agree with the scientists that we are getting pretty far along in the study of =volcanoes, and zi can't wait to learn more.

I think predicting volcanic eruptions is a really important. In many place in the world people have built right next to active volcanoes. I visited Pompeii and I could could see the what happens when a volcano erupts with almost no notice. When we visited, we were told that volcanologists felt it was not a matter of if Vesuvius would erupt, but when it would erupt. We were also told the magma layer under Vesuvius is much larger that the one under, for example, Kīlauea in Hawaii so there would seem to be a very large chance of another eruption of any size from Mount Vesuvius. No matter how good the evacuation plans may be a city the size of Naples would take a long time to evacuate. Only proper monitoring of a volcano and an accurate warning system would give people enough time to leave the area. This is why we really need a better warning system to tell us when volcanoes will erupt.
