1 2 3 4 5 Predicting weather is not easy. After all nobody can really tell the future. They are built on things we have learned and on our knowledge about how things work. Monitor, means to keep a record, like a journal, of all the changes that go on around a volcano day after day, year after year. A volcano may erupt and then sit quietly for hundreds or thousands of years. When they erupt, some volcanoes create enormous amounts of noise and can damage everything around them. They have learned that before an eruption, three things usually happen. By monitoring these events, scientists hope to predict when a volcano eruption is coming. It is common for small earthquakes to occur beneath active volcanoes. Some volcanoes send out weak vibrations all the time. While scientists are working on top of a volcano, they are exposed to many dangers, including poisonous fumes and the risk of a sudden eruption. The ride to Philadelphia didn’t take long and soon we were standing outside the mint. We just answered question number one, and it only took us a few minutes! Maggie crossed her arms and smiled when I finally caught up and finished filling in the answers. Maggie and I decided right then to be partners. He, too, was the president, and helped write the Declaration of Independence. The world has about eighteen major earthquakes each year. These plates are not like the ones you eat dinner from! Instead, they contain mile after mile of solid rock. As with volcanic eruptions, scientists know a lot about where earthquakes are likely to happen. But earthquakes are not like volcanoes. They do not seem to give off warning signals. Earthquakes seem to be even more difficult to predict than volcanic eruptions. There are now volcano observations in the United States. Scientists are not able to predict the exact time and place of an eruption. Volcanologists sometimes set up a network of seismometers around a volcano. A tiltmeter is an instrument that measures tiny changes in the slant of the ground. When hot magma rises up inside a volcano, the sides of the volcano may bulge, tilt, or crack.
