The Dawn at Isawa in Kai Province is a painting in a collection of works titled Thirty-Six Views of Mt. Fuji, by artist Katsushika Hokusai between 1830-1833. However, even though the series is named thirty-six views, Dawn at Isawa in Kai Province is the fifth of an additional ten paintings added onto the original set of thirty-six due to the overall popularity of Katsushika Hokusai’s work. The series, as the title states, contains thirty-six various views of Mt.Fuji and the areas surrounding the…

The Great Wave Off Kanagawa and The Inlet of Nobuto are visually very different, contrasting drastically in the conveyed emotional expressiveness. Both paintings clearly portray a great interconnection between men and nature, as to point out an important theme fundamental to Japanese art. However, in The Great Wave the nature seems to rebel against men, while in The Inlet of Nobuto it embraces them inserenity and harmony. Perhaps, this change in dynamics reveals various life circumstances the…

Marine seismic looking over applies the investigation of sound vitality and seismology to delineate structures under the seabed. Towed gadgets produce blasts of acoustic (sound) waves that go through the water and afterward skip back to recipients that measure the quality and return time of every wave. Listening to a voice reverberation in a void room takes a shot at a comparative guideline. The distinction, obviously, is that a human voice does not have the ability to infiltrate layers of rock.…

or can amplify the seismic waves and cause considered damages. The selected sites in Nile Delta area are the same sites where H/V spectral ratios were measured (chapter 3). 2-D seismic refraction modeling technique is applied to calculate the number of layers, their thickness, and VP – and SH wave velocities for each layer. The dynamic (elastic) characteristics are calculated to know the physical nature of each layer. Shallow seismic refraction technique. Seismic refraction…

This happens when the rock underground breaks suddenly. When the stress finally builds up, it releases, sending seismic waves which are also known as vibrations. The vibrations are responsible for making the ground shake. When the rocks break, the earthquake occurs. Earthquakes are all normal geographical behaviors of the earth. Earthquakes produce three types of seismic waves: primary waves,…

A tsunami is a seismic sea wave. Displacement of water forms a sequence of waves and this generally happens in an ocean or a large lake.Tsunamis are different because normal waves are caused by wind or tides, which is actually generated by the gravitational pull of the Moon and Sun. According to Source 1, the first recorded tsunami was back in 7000-6000 BCE and this was in Portugal but the primary cause is unknown. Since then there have been many tsunamis that have caused damage, two of the…

1. The Tasman Orogeny is represented in the basement rocks or eastern Australia. The rocks make up one third of Australia’s landmass. The orogeny extends along the eastern seaboard from the Tasmania in the south to Queensland in the north. In the early Paleozoic to early Mesozoic Australia was located on the eastern side of the Gondwana super continent. It was situated above Antarctica to the northeast of India. The tectonic processes that increased in the size of the…

These buildings withstand intense seismic waves by isolating the base of the building, and placing it on a rocking frame made of springs and boards. This technique is known as a seismic invisibility cloak, allowing the building to rock with the earthquake instead of swaying against it. This structure can be reinforced with materials such as structural steel with…

volcanoes, and other seismic disturbances of the sea floor. In the deep open ocean, tsunami waves are usually less than 1 meter and are hardly noticeable. However, they are much longer and travel much faster than ordinary wind waves. They can have wavelengths of 240 kilometers and travel at over 700 kilometers per hour. As tsunami waves approach the shore, shoaling occurs and the waves become dangerous. Shoaling occurs as the tsunami hits shallow coastal waters, and the trough of the wave slows…

years in a pie chart. The Great Chilean Earthquake accounts for nearly 20% of the total global seismic moment release. At a moment magnitude of 9.5, the earthquake caused astronomical amounts of damage to the Chilean coast, not only from the initial shockwaves, but also from the subsequent aftermath of tsunamis and volcanic eruption2. The earthquake came at a time when instruments used to measure seismic activity and warn of imminent hazards were…
