Personal Response 5: Earthquakes

Oh My, The earthquake in china (sichuan) makes me worried about singapore.Will it get quakes to? It just makes me wonder.Well its just the earths core.What is wrong with it? is it just something that happens randomly or supposingly. If there was a device that scientist had invented to detect earthquakes, we would be evacuated to a safe place i guess. but i wish that there would not have been any earthquakes in the pastfew years.
