    different kinds of material that can erupt from a volcano. Products of eruption come in three forms; lave flow‚ which can be Basaltic‚ Andesitic or Rhyolitic lava. A volcano also erupts pyroclastic debris (when lava flies into the air and freezes) and gases. 2. Contrast a pyroclastic flow with a lahar. Pyroglastic debris are blasting clots of lava‚ and the lahar are like mudslides that can reach up to 50km per hour. When the lahar stops moving it creates a layer of volcanic depris‚ (which can contribute

    15 IV. Bibliography …………………………… 17 Introduction The term volcano can either mean the vent from which magma erupts to the surface‚ or it can refer to the landform created by the solidified lava and fragmental volcanic debris that accumulate near the vent. One could say‚ for example‚ that large lava flows are erupted from Kilauea volcano in Hawaii‚ the world volcano here signifies a vent. Volcanoes are not the realm of any single scientific discipline. Rather they require study from many scientists

    travel down slope from a volcano. The Mount St. Helens pyroclastic flow spread as far as five miles north of the crater. The hot lava flows and suffocating ash falls destroying plant and animal life. The eruptions are over‚ but consequences go on. What happens to the surrounding environment after such an eruption? The Earth repairs itself from the destructive effects of the lava‚ gases and ash spewed by the eruption of Mount St. Helens. It is the short-term hazards posed by volcanoes that are balanced

    Tectonic Activity and Hazards Discuss the relationship between the nature of tectonic hazards and human responses to them. The Mount Pinatubo eruption in 1991 is an example of a tectonic hazard. The response to this hazard will be different to the response in Iceland to the Mount Pelee eruption. The human responses to tectonic hazards are affected by several different factors: the income level of the location‚ the frequency‚ the magnitude‚ the population density of the area the hazard takes place

    environment. The extent of volcanic hazards can vary due to two factors; physical factors such as the type of volcano and human factors such as the population density in the area. Volcanic hazards can also be placed into two phases: primary hazards such as lava flows and gas emissions; there are also secondary hazards such as lahars and landslides. The management of volcanic hazards are done through preparedness and planning where through prior risk assessments with monitoring the effects are mitigated.

    Grímsvötn volcano is located near the center of the Vatnajökull ice cap in central Iceland. At a height of 5658 feet‚ it has the highest eruption frequency of all the volcanoes in Iceland. Grímsvötn volcano has a complex of calderas‚ of about six by eight kilometers in area‚ and a subglacial caldera lake sustained by geothermal heat. A caldera‚ a large‚ circular depression at the summit of a volcano‚ is formed when magma is withdrawn or erupted from a shallow underground magma reservoir. The caldera

    ------------------------------------------------- Erupted material Pāhoehoe lava flow on Hawaii. The picture shows overflows of a main lava channel. The Stromboli stratovolcano off the coast of Sicily has erupted continuously for thousands of years‚ giving rise to the termstrombolian eruption. Lava composition Another way of classifying volcanoes is by the composition of material erupted (lava)‚ since this affects the shape of the volcano. Lava can be broadly classified into 4 different compositions (Cas &

    Undara Lava tubes consist of a lava field remaining from a massive volcanic eruption of Mt Undara which occurred 190‚000 years ago. During the Cenozoic‚ there was wide spread igneous activity in Eastern Australia. Volcanism commenced in the late Cretaceous (approximately 70 Ma) and continued through the Cenozoic. The cenozoic is the current geological era. It began 66 million years ago and continues today. About 23.3 km³ of lava flowed from the Mt Undara volcano at an estimated rate of 1000 m³ a
