vegetationle changes, the lesson here, i think in general and this applies to,usgs, and national weather, we need to make sure the networks are in good enough shape to make these decisions. they don't cost a lot of money but you need to know the data out there is quite flawed and we need to take care of it and make sure in the future it's doing what it needs to for us. let me expand this. there's a very nasty fight going on on the future of some satellites right now. the fight involved climate centers on these centers and certain governments want to toss them in favor of weather sensors. weather is important but climate also is. it effects all of us. no data means no good research fundamentally. so i encourage you not to lose site of some of these bigger issues. >> very good. >> on that issue, we're right in the process of adding 17 rain gauges, 17 instant rain gauges. i looked at how much it is to install it and it's relative to a five million dollar a year budget is nothing. you ought to go back and look at what data you wish you had and start putting that in place for whoever will fol

the usgs says the tumbler was sense yensed nine miles southwest of san francisco city hall. it hit just before 2:30 in a depth of more than four miles. >> and here is an senseless crime. san francisco authorities looking for someone killing trees in golden gate park. 44 trees have been vandalized and five attacks. they were cut by a hand saw. others uprooted or stripped of bark. the latest took place on wednesday, when 14 young were sawed into two, about eight inches off the ground. officials admit catching those responsible will be difficult. >> for many kids, school is a save haven away from violence on the streets. during summer one school decided to promote peace through art. and the hope put on paper. >> students of lake view elementary in oakland attended a summer program to stimulate their brains and hearts. because of the outbreaks of violence in different parts of oakland, the school thought it would be a good idea to reflect on the need for peace. >> this is a story that is just unimaginable f probably i had to deal with as a child, i'm not sure what kinld of perso

. >> reporter: 15 usgs is have been killed in apps this week with 50 americans dead according to the military times online. >> this is a hard struggle. and general petraeus said very cleanly that it's likely to get worse before it gets better. >> reporter: a massive manhunt continues in afghanistan for two missing u.s. navy men. cbs news reports the taliban claims one is dead and they want to exchange his body for insurgent prisoners. >> [ inaudible ] >> reporter: the two servicemen were believed to be heading back to their base when they apparently ran into taliban fighters. there was a gun fight and a taliban representative said one was killed and the other was captured. u.s. military forces are searching earn afghanistan where they disappeared south of kabul. >> serves to remind of the challenges that we have and also the service and sacrifices that so many make. >> there is more evidence of the difficulties ahead. classified documents say while the u.s. spent $300 billion so far, the taliban is stronger than at any time since 2001 and the war is hamstrung by the loyalty of the af

the usgs just revised their probability. it's this. it's a virtual certainty we'll have an significant earthquake in next few years. it's going to happen and it's like to happen in the next 20 years. >> you should count on it. >> you should count on it. we're not talking about a possibility. we're talking likelihood or ineffability. as we move on -- >> can i point out one thing, one of the reasons they believe this is a certainty, not a probability, is there is a theory that the 1906 earthquake released so much energy, we had a period of quiet. that's over. before 1906, we had big earth quaiks on a regular cycle here. we had big earth quaiks over here. '06 released the earthquake energy. if you start traifg the fault, every 150 years there's a big earthquake on the hayward fault the last big earthquake was in the 1850s, so we're on that 150 year return cycle. on the san an drees, we had an earthquake down here. there's a belief what is happening is the earth quaiks are moving. two earth quaiks from now we'll have an ep center up here.

i will outline that in 2002, the usgs, the united states geological survey presented our earthquake prediction and that is there's a 99.7% likelihood of a 6.7 or greater earthquake hitting california but the key statistic is that 63% chance of that earthquake hitting northern california. that means that we are in the zone of the 30-year time frame for the earthquake to be hitting northern california. and again, a specific piece of data that i would like you to keep in mind is there's a 30% probability on the highward fault. what does that mean? we've not had an earthquake on the hayward fault for years and we hit our rupture interval in 2008. we should expect an earthquake on the hayward fault any day now. so all the work we do on seismic safety is very important. i will say that both haiti and chile had similar predictions and they were generally ignored. so we have our prediction. it is time to act urgently. any work that we do with the community actioplan for seismic safety and all of the seismic safety legislation that comes forward, i would just encourage you to act with urgency and move

the usgs says the quake was centered about three miles north-northwest of daily city. and it hit just before 2:30. service stopped to check track that's is standard. and no damage or injuries reported. and those things get our attention, of course. >> coming up next, several oakland schoolteachers accused of keating on tests. >> plus, a new challenge to san francisco law requiring warnings on cell phone autos and oscar grant's mother prepares for a first one on one interview since the verdict. we get insight into what jurors were thinking. >> i'm spencer christian. what affect will this low have on the weekend weather? i'll answer that in the accu-weather forecast coming up. >> and mystery whof is killing dozens of trees in golden gate park? stay with us. abc 7 news at 6:00 continues. >> closed captioning brought to you by mancini sleepworld. >>> a wireless industry trade group is suing sab san frn tonight. the pipers were filed today. it wants to stop the city from forcing store that's sell cell phones to post how much radiation each model emits. and it says they're e

. >> reporter: the usgs is sharing 38 years' worth of satellite photos from around the world, comparing for better or for worse how things have changed. this is shanghai in 1973, mostly forest and farmland. here it is in 2005, the cities colored in blue have exploded in population. here's a patch of rain forest in brazil back in 1975. here's that same 80-mile stretch 28 years later mostly farmland. to outsiders all this development is alarming. >> you could say it's alarming or you could say it's a wonderful thing if you are a farmer in that area and suddenly you have 20,000 hectars of wheat that you can plant and cattle. >> reporter: this is the gulf oil spill in may the white portion oil. the same view taken wednesday, the oil sheen spread dramatically. remember the devastating floods in north dakota last year? this is what fargo normally looks like. and here's fargo last year. the black area is the flooding. four miles wide and 20 miles long. >> we have before and after so we can compare conditions before and after. that's a useful tool to resource managers. >> reporter: perhaps the

in fact, congressman brady, i see here on the usgs website when you look how much recoverable oil is available in north dakota and montana, the u.s. geological survey estimates that the bacan formation has an estimated three billion to four billion barrels of -- quoting -- technically recovered oil in an area known as the bacan formation. yet, if the majority has its way, congressman brady, they would prohibit fracturing thousands of feet deep, far below any fresh drinking water, fracturing those formations and allowing us to get access to that recoverable oil and gas. this moratorium on offshore drilling is devastating to the gulf, damaging to the nation, but part of, i see, congressman brady, a larger pattern of behavior by this administration by this congress -- by this administration, by this congress until we can replace them come november is shutting down oil and gas exploration. is this what you're seeing? mr. brady: the cost of the drilling moratorium and human lives and jobs is an impact on people's lives and families. it's devastating. we face other threats, hear immediate

there has been a steep rise in consumption which means trends of going back to usg debt to fuel economic activity. that delays reconciling in dealing with these problems for another day. host: to paraphrase an old song, everything old is new again. if the behavior's do not change, where will this ultimately lead us? gue: it cannot go on forever. an analogy i will use is you are a customer in a store and you can spend more than you make in the store can extend your store credit. you can consume more than your income would allo but eventually the store will say, "i am not sure you'll be able to pay off that that." there is a line from herbert stein, what cannot go on forever will not. the question now is how these trends that go on forever, how they get resolved and whether this happens in an orderly way ward in a way that is more disasters. host: you write that obama renewed his call for a doubling of u.s. exports. that has been made more difficult given the value of the dollar has driven 7.5% against the other major currencies this year making american exports more expensive. explain how

usgs and the world's largest energy resources. is their energy and economic security and i thank the committee for the caucuses, are opening up a dialogue on hopefully stopping the war in years. this is a little less than an hour. >> good afternoon everyone. we are so pleased to have you here at the whitehouse at the launch of the national hiv/aids strate. this is such an important day, and it is important that we put this day in context. it has been 30 years since the hiv/aids epidemic first hit our country, and it has been 20 years since passage of their ryan white care act, and at this important marker in our history, we think it is imperative that we refocus our attention on the issue of hiv/aids and what we have to do in the united states to address this issue appropriately. it is also important to keep in mind wht this means for individuals, and for all of the statistics there is a human face behind them. we know that 1.1 million people are living with hiv in the united states. we know that 56,000 people are infected every y

i really have no problem usg article three courts in the war on terror. in manyases they can be a better venue. i think military commissions can be a good venue to prosecute war crimes, but the hybrid, the third bucket as we all talk about are tose enemy combatants that the court has deemed to be an enemy combatant but the evidence for whatever reason is not subject to criminal scrutiny whether it be a military commission trial or an article three trial or the evidence may be such that you under the rules of discoveryof both proceedings you couldn't divulge it without hurting national security. it's in those cases the 48 that thobama administration has identified that the congress needs to weigh in with the executive branch to understand that the law of attention is e only valid theory that you can hold someone in that third category. and when it comes to quite frankly the treatment of prisoners, it becomes about us, not them. %%love the geneva convention a a military lawyer. it is not an individual right. i want my country to abide by it to the fullest e
