- Earthquakes
● California is an area where are many earthquakes. Every day there are up to 14 little earthquakes, but most of them are so slight that they aren't even noticed. Since the beginning of this century there have been 3600 quakes which have registed over 4.0 on the Richter scale. (Only Earthquakes with the magnitude over ~4 are noticeably) In 1906, there was an earthquake measuring 8.3 near San Francisco. Because of the terrible destruction this earthquake caused, new laws were passed for building construction. This was useful in 1989, when a quake measuring 7.1 arose in San Francisco.
● It is estimated that within the next 30 years there will be another quake of the 8.3 magnitude. This will be called the “Big Bang”. So the Californians live under the constant threat of earthquakes. Residents are told to avoid putting heavy objects on shelves, to fasten cupboards to walls and in the case of a quake to get under a bed or table.
