The existence of earthquakes in a specific place is a mystery to some people. Some wonder why certain natural disasters like earthquakes are happening in certain areas in the world. Others associate it to the curse of God among people. Superstitious belief by others is clearly refuted by the scientific reason which science and technology emphasize the reason of the earthquake event.
The seismic waves coming from the earth's crust which travels in the surface results to an earthquake. Many countries in the world belong to the pacific ring of fire experience the earthquake. This pacific ring of fire is a zone where large numbers of quake tremor and volcanic activities are active. Earthquakes like volcanic eruptions usually happen in the part within and near the Pacific Ocean. The movement of plate tectonic plates which is 40, 000 kilometers large in the Pacific Ocean also affects the series of volcanic belts, trenches and volcanic arcs. It is for this reason that countries within the circum-pacific seismic belt are always subject to an earthquake disaster. Almost 90% of the earthquake events happen in the ring of fire. The largest and the strongest earthquakes are about 80% occur on the same area. Alpide belt extending from Java going to Sumatra within Himalayas, out of the Atlantic and including Mediterranean is the seismic region of about 5% to 6% of earthquakes on which 17% of this is the world's largest earthquakes. Another important fact that you need to know is the Mid-Atlantic Ridge which must be observed keenly by many seismologists because this is the third greatest prominent earth quake belt. This is a fact indicated in the ring of fire which is the direct outcome of the plate tectonics. This is where the real movement and crashes of lithospheric plates truly happening, making the earth's land layers move and smashed. The eastern part of the pacific ring of fire resulted to Cocos and Nazca Plate. Other plates like the South American Plate, Caribbean Plate, Pacific Juan de Fuca Plate and Northern American Plate are active plates that usually creating the earthquake in some countries within its bound of area. Some places which usually affected by the movement of these plates and suffer from earthquakes are South America, Central America, North America, Philippines, Japan, New Zealand, Tonga, Bougainville, Australia New Guinea, Sumatra, Mexico, Hawaii, Canada and other areas under the ring of fire.
Recently, the greatest earthquake in history with a magnitude of over 9 was in Japan, and which killed 15,805 people, with 4,040 missing, left 5,927 injured and more than 125, 000 buildings were destroyed. The Japanese government has for the first time experience a great crisis through this earthquake and tsunami that the Japan Bank has offered ¥15 trillion equivalent to US$183 billion for the purpose of stabilizing the market situations. This is the step undertaken by the Japanese after the overall cost of damage exceed to US$300 billion which was the biggest expense as per record of natural disaster.
