What's going on in Indonesia?

I felt weakened by the news yesterday afternoon when I heard on the news that an earthquake shook Indonesia once again, and a possible tsunami could occur. They've had more than their share of natural disasters this past few months and it seems like more is on the way. This morning when I woke up, it's all over the news, a tsunami just hit them, again. There's nothing I can do, I could cry for them but it won't help. I feel so helpless.
