Personal Response 5 : Earthquakes part 2

How often do they happen?

Did you know there are over a million earthquakes each year in all parts of the world?
But we don't notice most of them because they are so small.
Britain doesn't have a history of devastating earthquakes, but there are 200 to 250 on average a year, and about 30 of those can be felt.

Why is it dangerous after a quake?

Earthquakes are often followed by aftershocks.
These are smaller quakes which bring more damage to already weakened buildings and roads.
Land, especially hills, can also be damaged by earthquakes and can result devastating landslides and mudslides.
After the El Salvador earthquake in 2001, a landslide hit the small town of Las Colinas.
It buried 500 houses and killed 315 people. Many more were never found.

Why do Earthquakes happen?

Although the ground we walk on seems solid, the earth is actually made up of huge pieces of flat rock called tectonic plates.
These move very slowly, and where they meet is called a fault.
When the plates rub together, the movement forces waves of energy to come to the earth's surface. This causes tremors and shakes - and this is what causes earthquakes.

Are they dangerous?

Earthquakes can be very dangerous, if you are in the wrong place. They can make buildings fall down and set off landslides, as well as having many other deadly effects.
An earthquake which occurs on the seafloor can push water upwards and create massive waves called tsunamis.
These waves can reach speeds of up to 500 kilometres per hour and cause massive devastation to anything in their path.
Earthquakes are measured on the Richter Scale.
The higher the number on the scale, the more powerful the quake. The more powerful a quake is, the more damage it can cause.
Earthquakes have killed hundreds of thousands of people even though scientists are able to make buildings much safer than in the past.
Unfortunately many quakes happen in parts of the world where people can't afford to spend lots of money on safety measures.

Personal Response 4 : Child Safety Belt in School Bus

I take the school bus to school.My school bus number is bus 1.I think the children behave well in the school bus.I agree with Ms Karen Koh that safety belts should be installed in school buses.It is better to be safe than sorry. I do not agree with Mr Leow Beng Kiong's view that installing seat belts not only costly but also unnecessary as the children are on the bus for only about 15 minutes.Children, bus attendants and school do to make sure that children are safe when travelling in school bus and school do to make sure that children are safe when travelling in school bus.Children sould not run around the bus and put on seat belt.Bus attendants sould check on the children on the bus.School sould install seat belts on their school buses.
