What can we do when something bad going on our homeland?

I was chatting with my mom the last 3 days, when she told me that they having a heavy rain. We are still talking about the recent flood near at my aunt's place where some of my cousin help to rescue some kids. I can hear the heavy rain from outside our house in Philippines, I can tell how heavy it is by only hearing it. My dad called my mom don't have any idea why, then all of the sudden my little brother pop up on the cam and said " Ate (means elder sister) water is coming inside our house, oh no Ate" I was like is this kids telling the truth on me? or he just making fun only? Then my mom came and told me that the water is already in our kitchen, and the water on our garage is like a pool already, the water got inside our car too. I can't believed what mom telling me now, since I never experienced those kind of disaster in Cagayan de Oro ever since, I was worried and I feel bad, cuz i wasn't there to help and know what going on. The power shut off, and it makes me worried a lot, i cannot see what's going already. So I texted mom and she said there trying to do everything to stop the water from coming inside the house, but yet it did come. Being here far away from them feel me totally helpless, the only power I have are my prayers, and thank GOD they safe. Then only things we can do when things happen this way is to pray for them, is more powerful than some other things.
