the only one this is significant is calaveras. ive you an idea of the incredible amount of work being done in the field, i want to show you these photos. this tunnel that stands between us, located between the faults, that construction project started last summer, and is making great progress, the we have encountered some difficult situations in the field of geology. we have encountered methane gas in, which modifies the construction on this project, expanding to the middle of 2014. the work taking place in the water treatment plant is making great progress as well. it is one of the three main treatment facilities here, a massive amount of work is taking place in this reservoir. we are about what have we done with construction on this project -- we are about halfway done with construction on this project. as i mentioned, construction on the calendar is them -- calaveras a damn project, this will control the overall completion of the program, july of 2016. the bay tunnel is by far one of our most technically challenging projects. 5

this is nice to see -- degrading work taking place at the calaveras dam. the biggest challenges there will be to deal with the restriction associated unnaturally occurring asbestos as well as with a new storm water regulations. you should be where the dam is only one of two projects in all of california that received a risk level 3 project classification under the storm water prevention regulation. that will certainly make our work even more challenging. the other thing we need to deal with very carefully is working closely with enterprise to have them lower the reservoir level to accommodate our work as much as possible while not compromising the operation of our system. it is going to be a fine-tuning to try to meet both objectives there. the progress being made at the water plant continues to be very impressive. it has -- as shown the construction of the new chlorine contact basin. we have just completed the tunneling of the new pipeline under the creek. that was done without any problems. we are 50% complete in construction on that project. the excavati

the r locked. there are a couple of zones where we see small- moderate earthquakes like we saw yesterday. creeping calaveras fault does release stress because it produces moderate-large earthquakes on a regular basis. >>reporter: thursday's earthquake does not tell us when the next big one is going to hit. this is an animation of what a 6.8 earthquake would look like on the hayward fault. seismologists say, get prepared because the big one is coming eventually. >>louisa: in world news, turkey has experienced at least seven aftershocks cents a deadly 7.2 magnitude earthquake struck yesterday. more than two of the people have been killed. that number is expected to rise. >>reporter: it is the most powerful earthquake that turkey has experience in more than a decade. a 7.2 magnitude earthquake shook the eastern part of the country. emergency crews and citizens dug through debris and rubble from dozens of collapsed buildings, looking for survivors. racks of the glove of of the bus shocked residents filled the streets crying while some of the injured were carried out of dormitories and apartment buildings. victi
