and view of camelot. a new film taken the last night of president kennedy's life. good evening. americans have long thought of new zealand as a quiet little nation of postcards. stunning beauty. but today, we saw what happens a force the size of an atomic bomb starts to explode under the earth. in historic christchurch, rescue teams from all over the world are joining the frantic search for survivors. they can still hear tapping and moans from under the rumble. at least 75 people have died. more than 100 are missing. both numbers are climbing in a quake that measured 6.3. and abc's bob woodruff takes us into this day of chaos and fear. >> reporter: the quake struck just before 1:00 p.m. thousands raced into the streets.

some broke through office windows to escape. the damage, staggering. buildings flattened. sidewalks buckled. cars destroyed. people still trapped in the rubble. reports of some phoning out to rescuers from crushed office buildings. one woman pulled out alive. >> i was buried under part of the ceiling. when i looked out, i saw that we were on the road and people were looking at us. >> reporter: at this school, rescue workers searched for young survivors. across the city, bloodied survivors collapsed into the arms of loved ones. >> about two meters over, we would have been squashed. >> reporter: even the landmarks of this city were shattered. this 19th century christchurch cathedral before the quake and now. its steeple, a pile of rubble in the square and inside -- >> unbelievable.

>> the outside has completely caved in. >> we have been just hit by a devastating earthquake. >> reporter: this journalist captured these moments. >> the whole building was just rocking. and i looked across to another reporter who was just also hiding. he was just yelling back. just saying, the building's coming down, they're going down, they're going down. >> reporter: the earthquake is actually an aftershock of a massive, deeper 7.1 quake that struck new zealand last fall. that quake caused less damage and no fatalities, partly because it was nearly 30 miles away from christchurch. but the one yesterday was only three miles away. a also impacts, the tasmin glacier, the largest in new zealand. the force of the quake broke the glacier. knocking off a size of 35 empire state buildings, tumbling into the water.

the city continues to be rocked by aftershocks. at least 20 in the hours following the 6.3 quake. some caught on live television. tonight, the rescue efforts continue with help from teams from australia and the u.s., arriving soon. bob woodruff, abc news. and among the americans in christchurch when the quake hit, former u.s. senator evan bayh of indiana and his wife susan. he left the senate just last month. they joined me this afternoon from new zealand. senator and mrs. bayh, are you both all right? >> we're both fine. susan is a little shaken. she was down in the middle of the worst of it. but thank god, thank god, we're fine. >> mrs. bayh, where were you and what did you feel? >> well, i was at cathedral square, buying a souvenir, i was talking to a very nice man when the earth started shaking. this nice german man just took me by my coat, which i'm still

wearing, he threw me out into the street. there was a lady next to me probably, who had maybe a yard away had a piece of concrete the size of maybe half of a twin-sized bed on her upper half. you could see her feet coming out. she was in the middle of the street where she was supposed to be safe but the buildings and the narrowness of the street caused the building to come down on top of her. >> where were you, senator? >> i was at canterbury university, diane, about three miles or so from the center of the city. we were in the middle of a lunch when the quake hit. things started falling down. windows started shattering. finally, the president said, everyone under the table. so we literally dove under this table. about 15 minutes later, the first aftershock hit, and it was like, if you picked up a napkin and were shaking with your hand, it was this historic older brick and mortar building just being tossed all about. it was remarkable. what you realize is the randomness of life. there are dozens of families out there who would give up everything to have their loved ones back. and it's -- >> it's hard to -- >> keeping life in perspective.

>> again, we thank you so much, both of you. and it's wonderful to know that you are safe. and the descriptions are heartbreaking and we're so grateful to you. >> let's pray for the people in new zealand. and try to help them. >> let's say a prayer for these families. and now, we turn next to another showdown in the middle east. this time, a violent battle in libya. the bizarre ruthless 68-year-old leader, mo mar gadhafi, taking to the air waves and delivering a battle cry. alex marquardt is at the libya board tonight. >> reporter: tonight, dressed in brown robes, gadhafi took to the air waves to show his defiance. in a rambling and often incoherent address, he repeatedly called the protesters rats, saying they're young people who take drugs and who have been encouraged by foreigners. i'm a revolutionary, he said, i will die here. damn those who try to stir

unrest across libya. but it's too late. in the east, the country's second biggest city, benghazi, is now in the hands of the protesters. the bbc's john line is in eastern libya. >> there's still a fear that go gadhafi's forces could mount attacks here in the eastern part of the country. though, all the regular army and all the police here have all defected en masse to the opposition. >> reporter: in the west, the capital of tripoli is a war zone. forces loyal to gadhafi are firing on anyone and everyone. >> it's a massacre. there are bodies laying on the street. and none of us dare to go near those because there's a mosque very near us. and we have seen the snipers get on there today. >> reporter: today, a river of humanity flowed out from libya into egypt. carrying whatever they could on their backs. ? a border crossing. right over there, libya. all of these people are

egyptians who have been working in libya, now coming home to escape the violent. "the army was shooting at the people with live bullets," this man told us. blanlss rushed to the border to collect the wounded, as tents were set up to accommodate those fleeing. many were emotional as they took stock of where they just came from and tried to figure out where they were going. there's evidence tonight that support for gadhafi continues to erode. the interior minister has resigned, saying that he supports the revolution. and there are reports that say two warships have defied orders to bomb protesters defecting to nearby malta. diane? >> these are warships now heading away, into malta. thank you, alex. for everyone keeping track, a scoreboard of this fever of unrest in the middle east, here's the state of play. the force of revolution has now toppled regimes first in tunisia, then egypt. three more countries, libya,

bahrain and yemen, the long-time leaders are hanging on but not by much. and protesters are simmering in seven other countries. from morocco to iran. but of course, the most dangerous tonight is libya. and moammar gadhafi, the man now ordering troops to fire on his own people, has long tried to cast himself as a glamorous star in his own eccentric movie. as we saw, when he first appeared before the cameras yesterday, holding an umbrella, saying he would go to the protesters, but it was raining. he was born the son of a nomad and is considered one of the strangest men on the world's stage. here's martha raddatz on that. >> reporter: he was once a young and dashing army captain. today, he has bottled black hair. a penchant for outlandish apparel and much ridiculed phobias. from the mouths of diplomats, he has a intense dislike, or a fear of upper floors. a fear of flying over water.

and he is obsessively dependent on a small core of trusted personnel, especially his long-time ukrainian nurse, glyna. then, his legendary crew of all female bodyguards. a pistol-packing posse of 40, that the tabloids claim are also required to be virgins. in 1989, gadhafi's antics prompted abc's barbara walters to ask straight away -- >> we read that you are mad. does it make you angry? >> translator: of course, it irritates me. nevertheless, i consider or do believe that the majority of the ordinary people in the four corners of the globe, do love me, because they have different vision from that of the official governments. >> reporter: but gadhafi's outlandish antics should not mask his brutal reputation.

libya was implicated in a bombing of a berlin disco, which killed and injured u.s. soldiers. in the 1988 bombing of pan am 103 which killed nearly 300 people. for years after that, gadhafi worked to improve his reputation. paying millions to the families of the pan am victims. but now gadhafi's browal side has emerged once again. this time, flying in cargo planes full of african mercenaries who don't even speak the language to do his dirty work. trained killers gunning down residents and protesters in cold blood. martha raddatz, abc news, washington. >> and we are feeling the effects of what is happening in libya here at home. libya is the 17th largest producer of oil in the world. and there are shockwaves in the oil pricing. the price of oil jumped 8.5%. the biggest one-day jump in nearly three years. and gas line here at home hit the highest price ever posted in

the month of february, $3.19 a gallon. and now, we turn to that high seas hostage drama we have been tracking since friday. it came to a tragic end today. four american missionaries handing out bibles as they traveled are all died. somali pirates had stormed their yacht and jim sciutto has traveled through somalia and he brings us the details on this sad ending. >> reporter: the u.s. had been negotiating face to face with two of the pirates when, without warning, pirates on board the captured yacht, fired a protect-propelled grenade. they missed. but hearing the sound of small-arms fire on the yacht, the navy quickly launched 15 navy s.e.a.l.s. as they approached, some pirates raised their hands, appearing to

surrender. u.s. forces boarded without firing a shot. only to find two american hostages dead and two mortally wounded by the pirates. >> despite immediate steps to provide life-saving care, all four of the american hostages died of their wounds. >> reporter: but danger still lurks. s.e.a.l.s encountered more pirates. in all, they captured 15 pirates. >> may they rest in peace. >> reporter: back home in santa monica, california, fellow church-goers of jean and scott adams spoke of their mission, along with phyllis mackay and bob riggle, sailing the world to spread the bible. >> they wanted to do a tiny bit for this world. to make some difference. >> reporter: their worldwide tour took them through treacherous waters. more and more somalian pirates subjecting their hostages to torture, starvation and murder. pirates used to hover near the coastline of somalia.

now they're striking as much as 1,700 miles away. creating a danger zone the size of the continental u.s. and trapping more and more ships. when we visited somalia, we found hundreds of miles of unpatrolled coastlines and remote hideouts. and a supply of young somali men like this one, volunteering for a $200 million a year business, and now a deadly one for four americans. jim sciutto, abc news, washington. and still ahead here on "world news," what does talking on your cell phone do to your brain? a brand-new study. the fever of rebellion in wisconsin, traveling state after state. and a last look at camelot. president and mrs. kennedy, the night before the nation changed forever.

more than two-thirds of americans have cell phones. but one question, does heavy cell phone use hurt human health? linsey davis reports on a major new study, which, for the first time, shows cell phones do seem to have some mysterious effects on the brain. >> reporter: some are calling the study a landmark event in our understanding on how cell phones affect the human body. 47 participants had cell phones placed on their left and right ears. one cell phone was activated but muted. the other was turned off. after 50 minutes the researchers
