Nepal earthquake occurred on 25 April 2015 with a strength of 7.9 magnitude and re-experiencing an earthquake of magnitude 7.3 on May 12, 2015. Thousands of people are reported dead, many still undiscovered, injury, physical damage, and lead to a crisis on Nepalis. Judging from the history of natural disasters that occurred in Nepal, major earthquakes have occurred in Nepal in 1934, 1966, 1980, and 1988.
Each earthquake caused hundreds of thousands of deaths. Nepal itself is a country with levels of hazards (threats) earthquake is high based on the location of Nepal that are in the Indian and Eurasian continental plates that collide resulting in earthquakes.
Based on some of the analysis of the number of fatalities, injuries or physical damage is caused in Nepal itself has a vulnerability ( vulnerability ) associated with the threat of earthquakes, earthquake kit list some vulnerabilities was less unprepared citizens in the face of the possibility of an earthquake, because of the earthquake last in history occurred in 1988.
Many buildings are not designed or reduce the likelihood of anti-earthquake badly damaged by the earthquake, and the building that was the old age so easily collapsed in the quake. With the hazards and vulnerability is high, the fair finally many fatalities, injuries and physical damage caused by the earthquake.
WHO mentions three components of the disaster, the hazards , vulnerability and risk . Hazards (hazard / threat) is experiencing potential disasters that can impact on the loss of life, injury, or loss / damage to the material. Characterized catastrophic potential location, intensity, frequency, and the possibilities that can happen. Vulnerability is a condition of vulnerability caused by physical factors, social, economic, and environmental effects associated with hazards . Risk is the possibility of experiencing the negative impact of disaster damage or a combination of hazards and vulnerability .
In connection with the earthquake disaster Nepal, Indonesia can learn from such disasters as Indonesia also have hazards and vulnerability are high that has a risk of high as well. Indonesia prone to earthquakes and has proved one of the natural disasters that frequently hit Indonesia is an earthquake. Why is that, because Indonesia Indonesia covered by the Pacific ring of fire arc ( Pacific ring of fire ) as indicated by the chain of mountains of Sumatra, Java, Sulawesi, East Nusa Tenggara and Maluku.
In Indonesia, there are as many as approximately 129 volcanoes are still active and the number of volcanoes in Indonesia as much as 14 percent of the active volcano on earth. If the track circuit made volcanoes in Indonesia, length 7,000-7,500 kilometers and a width of 50-200 kilometers.
Indonesia is also located at the confluence of three major tectonic plates of the earth, namely the Indian Ocean and Australia in the south, the Pacific Ocean to the East and Eurasia. The third relative movement of tectonic plates and two other plates, the Philippine Sea and the Carolina cause earthquakes in the border area between the plates meeting and also lead to a fault-regional fault which then became the regional center of the earthquake source.
Referring to the history of the earthquake in Indonesia has resulted in the number of casualties could not be said a little, injuries, and damage to infrastructure. This is a proof of risk which is owned by Indonesia regarding the earthquake disaster is high. In addition to the hazards , Indonesia also has been questioned about its readiness in the face of the earthquake. Readiness in the face of the threat of earthquakes that can occur at any time can include how to save themselves when it is inside the building, while inside the building, and while traveling by car.
What if a big earthquake densely populated places and buildings like most areas in major cities of Indonesia ?. Not many of us are aware of the importance of disaster preparedness. How many of us who became aware after the earthquake Nepal? Do we have to wait after a new incident reacted to prepare? We should be able to learn from Nepal earthquake, that our country also has great potential to experience a similar incident and have plenty of evidence of the history of the earthquake that occurred in Indonesia to prepare for disasters that may occur at any time.
