So I'm Adrian Bursa I'm at the Scripts Institution of Oceanography, and I'm proud to say I'm a double alum two areas which could probably not be further apart one of scripts and one is the school of international relations of Pacific studies so very different careers, but I'm here to talk to you about the second one I'm actually here to talk about the drought not to harangue you about over watering your lawns but to provide you sort of perspective from a geophysicist whose job is to research crustal deformation from plate tectonics and earthquakes so seemingly as far away from drought and water as you can get I want to motivate this with sort of starting with these two images which are really iconic ones from the drought on the left is Folsom Lake in the summer of 2011 the lake is almost full this was after a fairly wet year and on the right two and a half years later sort of in the throes of this spectacular drought that we're having here in California this is january2014 you can see that the reservoir is almost empty now to put this in context Folsom Lake is actually a very important component of California's water storage and distribution system this system is designed to capture water from the rainy north and distribute it down to the park south which includes us here in Los Angeles and also to store water for four times of need and in fact the system has worked exactly as it was meant to and as it was designed to the problem is we're reaching the end of three years of drought we may have another and a system is stressed to capacity so if you saw my title it was when the rains failed that the mountains rise so what does all this has to do with mountains rising and in order to sort of steer you in that direction I want to introduce a bit of technology this is the Global Positioning System and essentially this station right here which is right next to Folsom Lake shown by that star is pretty much what you have in your phones sort of research grade, but it's the same type of thing and these stations are designed to measure millimeter scale motions of Earth's trust which is stupendous in terms of sort of knowing what's going around going on this wasn't available even a decade ago really the way that it is now and what you see with a station like this and this is the only time series I'll present today it's a little cut off here but what you have on the horizontal axis is years from time from 2005 to 2015 so about a decade and in gray are the actual station positions of this antenna here next to Folsom Lake and what you see in primarily is a seasonal signal and that's shown in black which when you remove that resolve to this red time series and this is showing us sort of long-term crustal changes the vertical scale is the vertical motion and millimeters so minus 22 plus 20 and what we're seeing here back in July 2011 this station was that about minus five millimeters relative to its long-term average and then here with the lake mostly empty is up...
