Mount Vesuvius

Mt. Vesuvius is one of a series of volcanoes which are located along a line or "trend" that parallels with the west coast of Italy extending north from Naples through Rome to Sierra. This is probably the best know volcano in the world. It is located in one of the most densely populated areas of Europe and is also where the Greek settlements were made more than 800 years before the Christian era. Therefore, the necads for this volcano are far more complete than any other. Vesuvius follows a arctic pattern which makes it possible to predict to a certain extent.

Pavlof Volcano

Pavlof is a composite cone volcano located in the southwestern region of Alaska. Pavlof is located about 600 southwest of Anchorage. At its summit Pavlof reaches an elevation of 8,262 ft (2518). The volcano consists of andestic magma, that contains an intermediate content of gases. Emission of lava and ash has occurred during the volcanoes eruptive stage. Other geologic events are also related to the volcanic activity at Pavlof. Seismic activity, mudflows, and flooding have also occurred due to Pavlof's eruptive process. Pavlof has been in a period of eruptive pause during the previous six weeks. Even during these pauses the threat of violent volcanic activity is always present. Fortunately the volcano is located in a fairly remote region and does not pose a great threat to many people.

POPACATEPETL

Popacatepetl is a strato-volcano located in Central Mexico about 27 mile (45km) west of the city of Puebla, and 39 miles (65km) east of the capital Mexico City. Over 30 million people live within view of Popacatepetl and hundreds of thousand of people would face serious danger if a major explosion took place. About 17 measurable, yet not extremely dangerous, eruptions have taken place over the last 500 years. Two of these eruptions have taken place in the last three years. These events occurred on December 21, 1994 and on March 5, 1996. The eruption on December 21, 1994 marked the beginning of a new stage of eruptive activity. On December 24, approximately 8,200 tons of ash had fallen on the Valley of Puebla, leaving a blanket of white ash. Volcanic bombs as large as 40cm were also thrown from the crater. Popacatepetl remained quiet for the next fifteen months, only to be reawakened early on the morning of March 5, 1996. At this stage, monitoring is kept at the maximum level. Unless people are willing to move, monitoring Popacatepetl is all that can be done.
