Transcript of Mt. Stromboli
Mt. Stromboli By Anna DiGiacomo Mt. Stromboli is located in the Aeolian Islands of Italy. Mt. Stromboli is a part of the Calabrian volcanic arc. The volcanoes of the Calabrian arc are formed by the subduction of the African tectonic plate under the Eurasian plate. Where is Mount Stromboli? What type of volcano is Stromboli? Mt Stromboli is a composite volcano, also known as a stratovolcano. Composite volcanoes are tall and conical. They are formed by many layers of hardened lava and rock fragments. What type of lava? The island of Stromboli was built by a series of eruptions of basalt and basaltic andesite lavas. When Mt. Stromboli erupts, it throws chunks of lava into the air. The lava sometimes falls as bombs (larger than 3 inches in size) and scoria (smaller fragments). This builds up and forms the steep sides of the volcano. Eruptions Mt. Stromboli is one of the most active volcanoes on Earth. It is famous for its spectacular eruptions which launch fountains of lava from its crater. Because these eruptions are so famous and well known, geologists use the word "Strombolian" to describe similar eruptions. These eruptions are mildly explosive and occur every 5-20 minutes. How much has Stromboli cost? Mt. Stromboli has been almost constantly erupting for 2,000 years. Because of this, it is impossible to determine how much damage the volcano has cost. However on January 3, 2003, the flank of Mt. Stromboli collapsed and crashed into the sea. Around 10 million cuic meters of volcanic rock and lava poured into the Mediterranean Sea. The eruption caused a tsunami that rocked ships 100 miles away. Thankfully, the eruption only put 3 people in the hospital though it cost over £600,000 worth of damage. Hazards of Mt. Stromboli The most serious hazard on Mt. Stromboli is the Sciara del Fuoco (Stream of Fire). If this sector was to completely collapse, it would displace huge volumes of material and possibly expose dike systems. It could also create a tsunami which would cause much damage if it reached any of the other Aeolian Islands or the Sicilian Coast. Environmental Impact There have been many studies to see if Mt. Stromboli's constant eruptions have any effect on the environment. These studies have shown that around particularly active volcanoes, traces of fluorine have been found in rainwater. This has a limited effect on the surrounding vegetation. It seems only annual crops are effected by the dangerous chemical, plants native to the island having long ago developed a resistance. Did you know? Because it has been erupting almost constantly for the last 2,000 years, Mt. Stromboli is commonly known as the "Lighthouse of the Mediterranean"Full transcript
In Jules Verne's novel Journey to the Center of the Earth, Axel and Otto Lidenbrock emerge from their journey through Mt. Stromboli
Mt. Stromboli has been baffling both vulcanologist and geologist for years. There are many theories, but no one knows for sure why the volcano has been so active for so many years. Bibliography http://geology.com/volcanoes/stromboli/
