(b) The Japan Trench subduction zone has hosted nine events of magnitude 7 or greater since 1973. The largest of these is a M 7.8 earthquake approximately 260 km to the north of the March 11 epicenter, caused 3 fatalities and almost 700 injuries in December 1994. In June of 1978, a M 7.7 earthquake 35 km to the southwest of the March 11 epicenter caused 22 fatalities and over 400 injuries. Large offshore earthquakes have occurred in the same subduction zone in 1611, 1896 and 1933 that each produced devastating tsunami waves on the Sanriku coast of Pacific NE Japan.
(c) The coastline here is particularly vulnerable to tsunami waves because it has many deep coastal embayments that amplify tsunami waves and cause great wave inundations. The M 7.6 subduction earthquake of 1896 created tsunami waves as high 38 m and a reported death toll of 22,000. The M 8.6 earthquake of March 2, 1933 produced tsunami waves as high as 29 m on the Sanriku coast and caused more than 3000 fatalities. The March 11, 2011 earthquake far surpassed other earthquakes in the southern Japan Trench of the 20th century, none of which attained M8. A predecessor may have occurred on July 13, 869, when the Sendai area was swept by a large tsunami that Japanese scientists have identified from written records and a sand sheet.
Ans. Eyjafjallajökull, also known as Eyjafjöll, lies south of the intersect between Icelands East Volcanic Zone (EVZ), a NE-SW trending rift system, and the E-W trending South Iceland Seismic Zone (SISZ). The EVZ is currently the main zone of divergence between the North American and Eurasian plates on the Icelandic landmass, with slightly less divergence currently occurring at the parallel Western Volcanic Zone. Eyjafjallajökull is an elongated structure somewhat resembling a shield volcano, which is ...Download file to see next pagesRead More

Geology in Hawaii
...How does geology influence humans in the project area? Geology is the study of the earth, the materials of which it consists of, the configuration of those materials, and the processes acting on them. It includes the living and non living organisms which have inhabited the planet. An essential part of geology is the study of how materials of the earth, organisms, processes and structures have modified over time. Geology in Hawaii imposes on the human beings vastly more than most individuals realize or acknowledge. Some areas are good for farming, while others are not, and some places have important resources, and others are. Individuals also acknowledge that mountains in...

...of 250 homes and the region’s infrastructure. Additionally, the mountain also comprises of crater glacier that has an ice thickness raging amid 1 to 2 meters, thus making it young geologically. The mountain besides having glaciated valleys during eruption incidences, it comprises of three rivers namely Toutle, Kalama and Lewis where their purposes entail recreational and power generation (Samson 17). For illustration, lewis, which feeds three dams mainly for hydropower production, is helpful to the park itself and society. The park has its contribution regarding environmental degradation setbacks that have affected the area besides humanity and wildlife. The frequent eruption incidences witnessed on the mountain...

The pattern made are referred as “scoria cone” and “spatter cones” cinndercones ara loosely packed leaving gaps to exist between rocks where water penetrates thus causing erosion after minerals have been leached. This weakens the rocks therefore forming such shape pattern. Question 20 The width is 1.06 miles. We do not have access to folder 3d required to answer these questions.

...The history and arguments about the origin of the earth and evolution have given many scientists sleepless nights trying to unearth what might have actually happened long before we came into being. Scientist hope that one day the matter will be put to rest by providing evidence and be able to prove to the world beyond any reasonable doubt that certain specific activities took place. Their progress is mainly centered on the rocks which are the source of their evidence. The discovery of rocks which will provide the evidence and chronological evidence was a great milestone. Religious divide on the other hand seem to disagree with idea of millions of years and squeeze it to before six days of creation (Dawkins. 2012). Having gone... history and...

Give three examples of metal sulfide minerals that have commercial value (provide names and chemical formulae). Give example locations where these sulfide minerals have been extracted. Sulphide and Sulphate minerals both consist of the element Sulfur. The Sulphate/sulfate minerals are the salts of sulfuric acid.

Geology Volcanoes&Earthquake Assignment8
... Magma, lava and volcanic eruption Magma, Lava and Volcanic Eruption Magma refers a molten rock found deep beneath the earth’s surface. During a volcanic eruption, magma is expelled onto the surface of the earth to form lava. After eruption, the lava cools and solidifies to form volcanic rocks called volcanoes. The chemical composition, viscosity and gas content of the magma controls the volcanic behavior. Red-hot lava is extremely dangerous to human being, property and environment. It can cause a wide destruction if it does not cool very fast and continues to flow. In February 1973, the town of Iceland experienced an aggressive volcanic eruption that threatened the town and its outskirts. An inevitable tide was moving red-hot... Magma, lava...

... Earthquakes affiliation: Earthquakes The prediction of the event of an earthquake in the future is impossible. The scientists or the USGS have never predicted one in the past. However, the scientific data can be used to calculate probabilities for potential earthquakes in the future. For instance, the probability of occurrence of a major earthquake in the next 30 years within the areas of San Francisco Bay and southern California is estimated to be 67% and 600% respectively. To improve the structures’ safety, the USGS concentrates their energy into finding ways to mitigate the hazards of these earthquakes. Animals are extremely useful especially in predicting an impending earthquake. Before destructive earthquake strikes animals... Earthquake...
