To help you in your personal response, I have prepared some questions below:

6. Do you think there will be an earthquake in Singapore? Why?




Do explore the link given. I hope you have learned more about earthquakes.I am eagerly waiting to read your personal response.Mr Ong

The cause is when there is a sudden release of the Earth's crust that creates seismic waves.Seismic is something that is caused in earthquakes.They can actually follow this when there is an earthquake going on , "Drop,Cover and Hold on".This may reduce injuries and death during earthquakes.Scientists can detect only when there is a mainshock . Mainshock are big earthquakes , foreshock are smaller earthquakes.Earthquakes was occurred in Sichuan,China(May 12 2008) ,Honshu, Japan(June 13 2008) ,Kepulauan Mentawai Region, Indonesia(February 25 2008) and many more.Earthquakes are usually caused when rock underground suddenly breaks along a fault.There might be an earthquake in Singapore. Maybe yes , maybe no.It depends if the Earth's crust creates seismic waves and it might move to our country.
