Great facts they helped me with my history, art and English work. The ash cloud could be seen from space and the volcano increased in size greatly due to lava deposition. Unfortunately volcanic eruptions and earthquakes cannot be prevented. My daughter has found this a really good site and I see her using all the time. It has helped loads with the science projects and geography topics.
This is helping me on my science project on examples of volcanoes. The government accepted help from the USA to help monitor the volcano as it erupted. The first sign of activity began in the spring of with a series of small earthquakes began. Learn how your comment data is processed. Both towns were coated in ash, as were local farms.
Impacts The towns of Chaiten and Futaleufu were evacuated. It is tectonically active with earthquakes and occasional volcanic eruptions. This was great very helpful. Predicting and preparing for volcanoes Unfortunately volcanic eruptions and earthquakes cannot be prevented. National 5 Subjects National 5 Subjects up.
Responses The national government brought in the army, air force and navy to evacuate the 5, locals and give them food and fresh water. The higher the sulfur content of these gases, the closer the volcano is to erupting.
The ash cloud could be seen from space and the volcano increased in size greatly due to lava deposition. The underlying causes Mount St. Chaiten is a small volcano in studt Chile in the Andes fold mountains.
Studyy, even before the eruption of Mount St Helens, scientists thought that the it might still be a few weeks away. Hundreds of small earthquakes are caused as magma rises up through cracks in the Earth’s crust. Predicting volcanic eruptions As a volcano becomes active, it gives off a number of warning bihesize.
Great facts they helped me with my history, art and English work. Ash clouds resulted in airline flights being cancelled. My teacher gave me a prize for that! When a volcano is close to erupting it starts to release gases.
Scientists can also check for gas emissions sulphur dioxide and increased thermal activity at the crater.

The authorities were able to evacuate people from the areas surrounding Mount St Helens, after the areas affected by the previous eruption and they set up an exclusion zone around the volcano.
Mount Etna Facts
All plant and animal life within a 25km radius of the volcano was killed, including fully grown trees. Friction and heat cause the plate to melt and, as it melts, molten rocks are formed.
It even helps my older girl who is 14 do her homework for secondary school. In May the volcano erupted cqse being dormant for 9, years. It has helped loads with the science projects and geography topics. Population Sixty one people died due to mudflows, being crushed to death and poisonous gaseswhile had to be rescued. The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate.
Thermal imaging techniques and satellite cameras can be used to detect heat around a volcano. However, as well as prediction, people need to be prepared for an eruption.
Mudflows poured down the valleys choking rivers with rock debris, killing fish and ripping trees from their roots. The greater the fase, the nearer the eruption and measuring the size of the volcanic cone shows the build-up of magma in the vent. Volcanoes are difficult to predict but, although they were unable to give a precise date scientists tried to predict the eruption of Bitesjze St Helens by measuring the frequency of earthquakes on the mountain.
