Journal 9: Earthquake

Hi Mr Lau, besides exploring the link you have provided, I have found out other information on earthquakes from other links. An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Here are some things we should do during an earthquake
-If you're indoors, stay there. Get under -- and hold onto --a desk or table, or stand against an interior wall. Stay clear of exterior walls, glass, heavy furniture, fireplaces and appliances. The kitchen is a particularly dangerous spot. If you're in an office building, stay away from windows and outside walls and do not use the elevator.
-If you're outside, get into the open. Stay clear of buildings, power lines or anything else that could fall on you.
-If you're driving, move the car out of traffic and stop. Avoid parking under or on bridges or overpasses. Try to get clear of trees, light posts, signs and power lines. When you resume driving, watch out for road hazards.
-If you're in a mountainous area, beware of the potential for landslides. Likewise, if you're near the ocean, be aware that tsunamis are associated with large earthquakes. Get to high ground.
-If you're in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.
I think it is possible for scientists to detect earthquakes, one example is using a laptop. Many laptops have an accelerometer, a sensor that detects motion and free fall, and that can be used to detect the intensity of earthquakes when a laptop shakes. One place where an earthquake has occured is in Sichuan, China. I think there are earthquakes in those countries because there are plates under the countries which might have fall and cause a fault line. From there, an earthquake occurs.I am not too certain that an earthquake would occur in Singapore as I feel that we are protected by GOD.
