8.2 Richter scale earthquake off the western coast of Sumatra

CNN -- An earthquake measuring a preliminary magnitude of 8.2 struck off the coast of Indonesia Monday -- on the same fault line that originated a December 26 earthquake that launched a deadly tsunami.

The quake occurred at 11:09 a.m. ET (1609 GMT), and is considered a "great" earthquake, the largest of seven grades.

The grades are very minor, minor, light, moderate, strong, major and great.

For the second time in just a couple of days after 3 months since the boxing day tsunami, an even stronger earthquake has occurred. The warning center reported the quake has even been measured up to 8.5 Richter scale. Authorities in the different regions affected have issued statements regarding the possibility of tsunami occurring.

Many survivors have not even recovered from the trauma they suffered, and another one struck. Blimey, if this doesn't wake us up on the importance of an tsunami warning system in place in the region, what will?

Let us hope this time it's just the earthquake.
