Wow thats really cool. I'm very interested in geology as a whole with earthquakes and Volcanoes. There is a volcano erupting in the Philippines right now. So I can see how this have can save lives especially in volcanic and earthquake prone regions.
More time given to individuals to prepare for imminent danger the better. I just hope some knucklehead doesn't hack it and shoot off false alarms... (Hawaii's oops.) :)
Great info & I'll be sure to follow you!
Thanks for sharing! Cheers!
