can also be seen as an economic impact. In 2002 a huge column of ash was thrown up from the biggest eruption in recent years and was deposited as far away as Libya. Seismic activity associated with these eruptions caused the eastern flanks of the volcano to slip by 2m‚ causing structural damage to many houses. Lava flows completely destroyed the tourist station at piano Provenzana and part of the tourist station at Rifugio Sapienza. The airport at Catania was forced to close as the runways were covered

Nevado del Ruiz is a volcano in Colombia‚ the northenmost and highest Colombian volcano‚ located at the in the northern most tip of the Andes in South America. Nevado Del Ruiz is a broad‚ glacier-covered volcano that covers more than 200 square kilometers. Has the volcano erupted before? In 1595 and 1845 summit eruptions melted snow and ice and produced mudflows that traveled tens of miles from the volcano‚ these mudflows were confined to the valleys that drain the volcano. The 1595 eruption sent

range‚ and certainly is the most active volcano in the area today. In fact‚ it has probably been the most active of the Cascade volcanoes for over 4000 years. If the eruption of 18th May 1980 follows the pattern of previous eruptions the mountain will remain very active for perhaps ten or twenty years before beginning to quieten down again. The 1980 eruption was the first time that it was possible to use modern technology to carefully monitor a volcano as it built up towards a violent eruption

an island volcano that lies in the Sunda Strait. The scientists of the time struggled to comprehend the destruction that resulted from this great explosion. The results from the examination of the destruction established a landmark in learning about volcanoes. But let us back up a bit and learn exactly what happened before the Great Explosion happened. In 416 A.D. Ancient Krakatoa destroyed itself in a massive eruption. Over the next 1200 years‚ minor eruptions rebuilt the volcano. These small

Abstract— This paper describes our experiences using a wireless sensor network to monitor volcanic eruptions with low-frequency acoustic sensors. We developed a wireless sensor array and deployed it in July 2004 at Volc´ n a Tungurahua‚ an active volcano in central Ecuador. The network collected infrasonic (low-frequency acoustic) signals at 102 Hz‚ transmitting data over a 9 km wireless link to a remote base station. During the deployment‚ we collected over 54 hours of continuous data which included

This is one of the most interesting questions scientist ask why does this chemical reaction happen when you mix this stuff together . Why do baking soda and vinegar react with each other? This happens because of an acid base reaction and also because baking soda is a bicarbonate and vinegar is an acid and when you mix them together fiss start to show up . What does this have to do with my science fair project? This has to do with my science fair project because it shows how the volcanic

Using the technology‚ they can also predict when a volcano is probably going to erupt. In a MEDC‚ the people are more educated and know what to do in a situation like a volcanic eruption. They are aware of how they are supposed to deal with it and protect themselves and others. They are also able to evacuate

in class‚ we have learned many things about the earth and its elements that are within it. One thing about the earth that we have learned about is volcanoes. The text describes a volcano as a hill or a mountain that is constructed by the extrusion of lava or rock fragments from a vent (Plummer‚ 2007). A volcano consists of a volcanic cone‚ craters‚ vents‚ necks and fissures within its physical form. But volcanoes have more to them that isn’t seen so easy from a distance‚ volcanoes also

A supervolcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1000 km cubed. This is about 1000 times bigger than a normal volcanic eruption. super volcanos don’t tend to be visible from the ground as they are so big. This is because the caldera‚ a large volcanic crater‚ are so big‚ in the case of Yellowstone it is over 40 miles across‚ so people do not recognize it as a volcano. Super volcanos occur when magma in the mantle rises into the crust from a
