why nuclear weapons experts call those north korean pictures alarming. couple that with the underground test of what north korea called a hydrogen bomb and what a u.s. intelligence official said was certainly a test of an advanced nuclear device. under secretary general jeffrey feldman described the blast to an emergency session of the u.n. security council. >> experts have estimated a yield of between 50 and 100 killo tons or on average more than five times more powerful than the weapon detonated over hiroshima and at the low end of the yield of a modern thermo nuclear weapon. >> reporter: it is not known if the device detonated underground would fit in the warhead north korean scientists showed off to kim jong-un. it is also not known if the warhead is a model or the real thing, but it is clear north korea is closing in on its goal of developing a thermo nuclear warhead that could fit on a long-range missile capable of reaching the united states.

warhead could be detonated at high altitudes for a superpowerful electromagnetic pulse attack. >> an electromagnetic pulse, which triggered by a nuclear weapon would aim for widespread damage and destruction for electricity grids and sensitive electronic, including satellites. >> reporter: north korea will need new tests to know if the warhead can stand the stress of reentering the atmosphere after an intercontinental flight, but right now it seems like only matter of time. elaine? david martin, thanks. president trump had his representative at the united nations deliver the latest warning to kim jong un today. here's chief white house correspondent major garrett. >> reporter: at the second security council session on north korea in a week, u.s. ambassador nikki haley said enough is enough. >> the time for half measures in the security council is over. the time has come to exhaust all of our diplomatic means before it is too late.

korea's reported test of a hydrogen bomb in defiance of new u.n. sanctions shows dictator kim jong-un is spoiling for a conflict. >> he is begging for war. war is never something the united states wants. we don't want it now. but our country's patience is not unlimited. >> reporter: that followed an ominous warning from defense secretary james mattis after a sunday national security meeting at the white house. any threat to the united states and its territories, including guam or our ally, will be met with massive military response, a response both effective and overwhelming. >> reporter: on twitter over the weekend, president trump accused south korea of toying with talk of appeasement, and he said north korea's leader had become a threat and embarrassment to china, the country's closest ally and trading partner. south carolina republican lindsey graham outlined the scenario where economic and

>> there will be an attack by the united states against his weapons systems. i'm assuming the worst. i'm assuming we drop one bomb, he fires at south korea and maybe japan. >> reporter: on cbs this morning, former deputy c.i.a. director mike morrell outlined another option. >> his acceptance with where they are and where they're going with detainment and deterrence, i think that's where we'll end up. >> reporter: the president spoke by phone today with south korean president moon jae-in and the two leaders agreed to amend the joint treaty between the united states and south korea, allowing south korea to expand, increase, if you will, the size and payload of its warheads on its missiles, and for the south to buy billions more in u.s.-made weapons. elaine? >> quijano: major, this appears to be a very scary situation. a lot of americans might be asking: are we closer to war? >> reporter: the two nations are quite clearly on a collision course.

so are the two nations closer to war than they were say a month ago? yes, they russia but closer does not mean close. diplomacy and economic pressure still have a long way to go. the treasury department is writing a new round of sanctions as we speak, and if there is a curtailing or ending of u.s. trade with nations that deal with north korea on a regular basis, like china, that could also change the calculus. >> quijano: major garrett at the white house. major, thanks. fear of war is greatest in south korea. asia correspondent ben tracy is there. >> reporter: south korea put on a dramatic show of force monday, flying fighter jets and launching ballistic missiles. this military drill was designed to simulate an attack on north korea. seoul and its ten million people face the most immediate danger from north korea's growing arsenal of weapons. south korea is now allowing the united states to install four more thad rocket launchers, part of a controversial missile defense system.

trump has accused south korean president moon jae-in of trying to appease kim jong-un by favoring negotiations. this man in seoul said, "both kim jong-un and trump are unpredictable leaders. to be honest, it would not be strange if a war broke out." kim jong-un has rapidly accelerated his weapons program, conducting 18 missile tests so far this year, and what he would actually do with a nuclear-tipped missile is still not clear. >> the good news is that north korea is rational, they want to survive. >> reporter: daniel pinkston teaching international relations in seoul and is an expert on north korea's weapons program. is getting north korea to abandon these weapons a realistic goal, or is that a fantasy? >> it would be analogous to the pope coming out tomorrow and abandoning jesus christ. it's something so embedded in their belief system and their identity that it would be that

>> reporter: the south korean defense ministry says it is seeing signs that north korea might be preparing to launch another intercontinental ballistic missile that could coincide with a major holiday that takes place in north korea this coming weekend. elaine? >> quijano: ben tracy in seoul. ben, thanks. late today florida governor rick scott declared a state of emergency ahead of irma. the category four hurricane, with winds of 10mph, -- 130mph, is expected to strengthen tomorrow night as it approaches the eastern caribbean, including antigua and st. martin. hurricane watches are up in puerto rico and the virgin islands. irma may take aim at south florida as early as sunday. more than 50,000 texans who were displaced by hurricane harvey are staying in government-funded hotel rooms. harvey is now blamed for at least 59 deaths. texas governor greg abbott says the total damage could reach

it's important the clean up fast because of what contaminated water leaves behind. floodwater can also harbor dangerous bacteria, which can enter the body through cuts and scrapes. >> we went to a couple spots where you saw nails. you just don't know if you're going to public yourself and, bam, there you are, now you're at risk for tetanus. >> reporter: despite the hazard, residents have no choice but to clean up. >> some of this might be sewage waste, you don't know. >> reporter: but still you're out here? >> we have to get it cleaned up to get back in. >> reporter: on top of all of that, many of the estimated 100,000 homes that were flooded now have mountains of debris in front of them, still soaked with dirty water, they're sure to attract all kinds of critters that carry their own diseases. elaine? >> quijano: incredible challenges ahead. michelle, thanks. president trump will announce tomorrow that he is keeping a campaign promise and ending daca. that is the obama-era program
