Reаding 2 Vоlcаnоes Jаpan's Mоunt Fuji and Mexico's Popocatepetl are two of the world's best known volcanoes and are considered special by many people in those countries. However, there are thousands more volcanoes in the world, and at least 1,500 are currently active. One of them, Italy's Stromboli, has been erupting for at least 2,400 years. Careful studying of volcanoes has given us detailed information about various aspects of these powerful forces of nature. Although Stromboli has been almost constantly erupting for over 2,400 years, most eruptions do not last nearly that long. Currently, there are about 15 volcanoes in the world that have been actively erupting for the last 30 years. On the other end of the scale, about ten percent of volcanoes have eruptions which last for just a single day. The majority of the eruptions last three months or less. This means the average time from beginning to end is usually about seven weeks. Looking today at the number of volcanic eruptions in the past few hundred years, it would appear that they are becoming much more frequent over time. However, when researchers tracked the growth in reported eruptions along with the growth of the human population, they realized that volcanic activity wasn't actually becoming more frequent. Instead, as people spread over more areas of the earth's surface, the monitoring and reporting of volcanic activity increased with the growing population.
