Introduction Danger can pose a danger for everyone. Accepting risk related risks determines where and how you live. As a human being, when we choose to send our daily life, we accept certain risks. Danger is occasionally in an emergency situation. A tornado in the Midwest, a hurricane on the Gulf, and an earthquake in California are the dangers of residents living in these areas to live. In this article, we will examine the risk of causing disasters and requiring emergency administrator response.
In 1964, Anchorage, Alaska, 1971, San Fernando in California, and the Northridge, California earthquake in 1994, vulnerability of reinforced concrete framework was discovered and the development of modern seismic technology was promoted . . Ductility of the building is the most desirable feature of earthquake resistance. This requirement is defined as the ability of the material to deform significantly before it breaks down. In many cases, the low performance of the building is due to insufficient strength and rigidity of the earthquake proofing system as a whole. In addition, poor distribution of strength and stiffness in continuous stories results in soft story formation. In addition, the lack of proper loading path through the structure results in partial or complete failure of the structure.
When I was 5 years old, a Beiling earthquake occurred. When my family lived in Northridge, I was in kindergarten. If you are not from Los Angeles, I do not know where Northridge is, but anyone living in Southern California in 1994 knows Northridge is "Oh, it's an earthquake." . In my dreams, the trailer is breaking my house. Then my mother will pick me up from my bed; detaching the room from my parents means I was being brought back for the first time This knowledge has been comfortable and inner happiness for years It is the secret source of.
On June 28, 1992, an earthquake of magnitude 7.3 occurred in most of Southern California at 4:57 am local time (UTC time 11: 57). As many people think that it is not a so-called "big thing", it is still a very strong earthquake. Shaking lasted 2-3 minutes. Although the earthquake was much stronger than the Northridge earthquake in 1994, the position in the Mojave desert with low population density minimized the damage and loss of human life. The earthquake was a right-lateral deviation earthquake containing several different faults of 75 to 85 km (47 to 53 mile) in length. The names of the people involved are Johnson Valley, Kickup (aka Randes), Homestead Valley, Homestead / Emerson, Emerson Valley and the Campolol Fault.
