![]() ![]() The crust near the continental margins (blue) is about 200 million years old. Landslides and damaged dams were another major consequence of the earthquake.Age of the Atlantic oceanic crust. Roads, railways, airports and so on were damaged or destroyed. Apart from the major destruction of houses, the region’s infrastructure was damaged significantly or destroyed completely in some places. ![]() In 2007, it was estimated that a major earthquake was going to take place within 30 years.Īs has been mentioned above, thousands of lives were lost, and thousands of people were displaced. It is also necessary to note that a historical approach was also applied. Numerous seismometers were used to measure and predict the earthquake. The agency also sent warnings concerning the upcoming tsunami around 10 to 30 minutes before it reached the coast. The Japan Meteorological Agency sent warnings concerning the earthquake seconds after it occurred and around a minute before it reached cities (Smits, 2014). This earthquake feature involved almost 20,000 human losses, almost 367,000 people affected, and the economic damage of $210 billion (Alcantara-Ayala, 2014). The Tohoku earthquake caused the tsunami, landslides, floods, fires, and accidents in the nuclear power plant mentioned above. ![]() The earthquake was a result of another massive earthquake that took place in 869. The earthquake occurred due to the subduction of the Pacific Plate under the Honshu plate (Smits, 2014). The earthquake of such magnitude caused another natural disaster, a tsunami, which in its turn, led to a number of nuclear accidents in the Fukushima Nuclear Power Plant. This was an earthquake with the magnitude of 9.0 M w and five aftershocks with the magnitude of 7 as well as hundreds of aftershocks of M5 (Alcantara-Ayala, 2014). The Tohoku earthquake of 2011 is one of the deadliest natural disasters that took place in the world. Other types of deposits created by divergent plate boundaries are salt and gypsum that are found on the surface of evaporated lakes. Clearly, this process is very slow as it requires millions of years, but people now use the results of the activity of divergent plate boundaries. Importantly, some minerals ‘travel’ towards the surface, and when they interact with ground water, such important resource as copper is created (Searle, 2013). These mineral resources are still widely used in various industries. These geologic features form such valuable minerals as iron sulfide and lead sulfide (Searle, 2013). It is necessary to note that one of the most important economic activities associated with a divergent plate boundary is the extraction of natural resources. The formation of deposits is also a ‘product’ of divergent plate boundaries’ activity. Furthermore, shallow earthquake activity is another feature of the divergent plate boundary. For instance, submarine mountain ranges are created, or the ocean basin can be widening (Searle, 2013). As to geologic activities associated with the divergent plate boundary, it is possible to mention the creation of new seafloor. ![]()
