I just have read somewhere that Android has launched a system in which people can detect an earthquake before its prevalence, and I guess it is the best thing a technical forum can do. I dont have much clue on that, so if anyone has anything to share, I will be thankful.

Hello all. I just have joined the forum because I have a question regarding drought management. If, for example, a government gets to know about the upcoming drought, what are the prerequisites to judging the extent of its prevalence, like how long will it last? Let me know Kindly I will be every thankful.
