Volcanoes affect people in many ways‚ some are good‚ some are not. Some of the bad ways are that houses‚ buildings‚ roads‚ and fields can get covered with ash. As long as you can get the ash off (especially if it is wet)‚ your house may not collapse‚ but often the people leave because of the ash and are not around to continually clean off their roofs. If the ashfall is really heavy it can make it impossible to breathe. Lava flows are almost always too slow to run over people‚ but they can certainly

Volcanoes and Earthquakes test Bew c. 1. Where do earthquakes occur? Earthquakes occur at breaks in the earth’s crust called the fault lines. 2. What causes Earthquakes? Tectonic plates pushing‚ pulling‚ slipping past each other increasing the stress and causes elastic rebound to happen. During elastic rebound‚ energy is released and some travel as seismic waves‚ which cause an earthquake. 3. How do earthquake waves travel and what are the various types of waves? Body waves

It will also discuss how the climate was affected by the eruption and also its influence on the hydrological cycle of the earth. Mount Pinatubo is one of a chain of composite volcanoes (see Figure 2) that constitute the Luzon volcanic arc (Wolfe‚ E. & Hoblitt‚ R.‚ 1999). Composite volcanoes‚ also called Strato-Volcanoes‚ are formed by alternating layers of lava and rock fragments (Oracle Thinkquest‚ 2011). The arc parallels the west coast of Luzon and reflects eastward-dipping subduction along

DO VOLCANOES HAVE A DESTRUCTIVE POWER AS WELL AS POTENTIAL BENEFIT Volcanoes are usually depicted as towering mountains missing a chunk out of the top from which steam‚ ash and lava spew forth. In reality‚ a volcano is any spot on the surface of the Earth where lava flows. Magma finds its way upwards along fissures or cracks in the planet ’s crust and bursts out onto the surface‚ resulting in a volcano. Magma that flows out of a volcano is called lava. If it comes out of the volcano in an explosive

The eruption of Mt. Vesuvius in Pompeii was in the year of 79 CE on August 24th. The volcano stood 6‚500 feet high and was 12 miles north of Pompeii‚ but the eruption had strong winds‚ causing tons of ash to rain on Pompeii and its neighbors.

Very quickly there was 9 feet of ash that covered the entire city‚ and

Hekla‚ Katla‚ and Laki are located in the south of Iceland. All of them have a distinct personality. Iceland has so many threating volcanoes as a result of its unique location. Iceland lies in the North Atlantic where two of the earth crustal plates are pulled apart. Below Iceland is a hot spot‚ where Molten material rises to Earth’s surface forming active volcanoes. Laki is well known to be a fissure volcano meaning that it erupts in a linear vent system. Laki does not erupt from a single crater
