Alfred Wegner used for his theory of "Continental Drift"? 10. What was Harry Hess’ major contribution to the understanding of Plate Tectonics? This a map showing the distribution of earthquakes from 1990 to 1996. A similar map is on page 54 in your text. 11. Are the earthquakes randomly distributed? 12. Are the volcanoes randomly distributed over the globe? 13. What is the age of the oldest sea floor? 14. In the Atlantic Ocean‚ where is the oldest sea floor? 15. Where is the youngest sea floor

is the normal relationship between number of occurrences of a particular type of event and the size of such events? * numerous small events‚ a few larger events‚ and only rarely a giant event [p. 6] 5. When is a large event such as a major earthquake not a disaster? * when it happens in a remote area and does not affect anyone [p.3] 6. When people incur a significant loss from a natural disaster‚ who is most commonly to blame‚ and why? * People themselves are to blame because they place

eastern island of Japan‚ is primarily mountainous‚ but most of Japan’s flat land is found here. There are several active volcanoes located here. Such as Mt. Fuji‚ Japan’s highest mountain. Summers are reasonably warm and wet‚ possibly humid. Winters are mildly cold and in some cases dry. The island of Kyushu‚ based on the southern areas of Japan has several active volcanoes. It also consists of crater lakes and hot springs. If you go to the warm seas near the coast‚ coral reefs can be found. The

Tsunamis are barely felt as a ripple on the ocean’s surface‚ but as the waves reach land‚ they increase in size as the water becomes shallower. Japan earthquake and tsunami At 2:46pm Japanese time‚ on March 11th 2011‚ an earthquake with the magnitude of 9.0 took place 100km of the coast of Japan‚ and was the 5th most powerful earthquake ever recorded.

large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40‚000 km (25‚000 mi) horseshoe shape‚ it is associated with a nearly continuous series of oceanic trenches‚ volcanic arcs‚ andvolcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.[1] It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. About 90%[2] of the world’s earthquakes and 81%[3] of

Pat I. Volcanoes and Volcanic Hazards (Chapter 4) 1. Between 2001 and 2012‚ 41 volcanic events occurred worldwide. 2. 11 eruptions with VEI>=3 erupted from 2001-2012 3. Some volcanoes that were erupted and associated with tsunamis are: * Name: Stramboli Eruption type: stratovolcano Location: Italy * Name: Soufriefe hills (2003) Eruption type: stratovolcano Location: W indies * Name: Soufriefe hills (2006) Eruption type: stratovolcano

or an extra hot plume of molten rock. This happens when heat rises as a thermal cloud from inside of the Earth. Heat and pressure at the bottom of the tectonic plate forces magma to form which then rises through cracks and erupts to form volcanoes. As volcanoes move away from a hotspot‚ they start to erode and become inactive. Maui is the third oldest volcano of the main Hawaiian islands and could still erupt one more time. Haleakalā or the East Maui Volcano is also a shield volcano or a broad‚ domed

“scientific study of the origin‚ history and structure of the earth”. It involves understanding earth’s processes‚ materials and its effects on all forms of life. From earth elements such as rocks and mountains to natural phenomenon such as volcanoes and earthquakes‚ the field of geology encompasses a wide range of concepts fundamental to many professions and to civilization in general. Scientific disciplines such as civil engineering and environmental sciences‚ for instance‚ rely on a deeper understanding

include floods‚ severe weather‚ volcanic eruptions‚ earthquakes‚ and other geologic processes. A natural calamity can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover. A natural calamity are the side effects or the after effects of natural issues or hazards like flood‚ volcanic erosion‚ land slide or earthquake which will lead to the human‚ monetary and environmental

forces are largely outside the control of the people whom it effect. Some of the natural disasters include earthquakes which occur in seconds‚ cyclones and landslides in minutes‚ flash floods and tsunamis in hours‚ and volcanoes in weeks. Some of these disasters can be predicted well in advance‚ these include cyclones‚ tsunamis‚ volcanoes etc. Some cannot be predicted like earthquakes‚ flashfloods‚ and landslides.
