>> John: THIS IS SUCH AN. UNBELIEVABLE NATURAL EVENT HERE. WATCH THIS. NEARLY 100 PEOPLE DEAD AFTER. MASSIVE FLASH FLOODS SWEPT. THROUGH THE HIMALAYAN REGION. HUNDREDS REMAIN MISSING. INCLUDING VISITORS FROM ALL. AROUND THE WORLD. OUR FOREIGN CORRESPONDENT. JEFF PAUL IN LONDON. THE DEVASTATION WAS STUNNING. >> TOUGH IMAGES. AUTHORITIES FEAR WITH SO MANY.

MISSING THE NUMBER KILLED WILL. INCREASE LIKELY. WE WANT TO WARN OUR VIEWERS SOME. OF THE IMAGES OF THE LANDSLIDE. ARE VERY DISTURBING FOR YOU THIS. IS SECURITY FOOTAGE FRED YOU CAN. SEE PEOPLE RUNNING TO FIND. SAFETY AND THEN A MASSIVE WALL. OF WATER, MUD AND DEBRIS SWEEP. THROUGH THE VILLAGE. THE FORCE WAS SO STRONG IT QUITE. LITERALLY RIPPED AWAY CARS AND. TORE APART BUILDINGS. THE EXACT CAUSE IS UNCLEAR BUT. SOME ARE POINTING TO A MAGNITUDE.

4.4 EARTHQUAKE THAT STRUCK THE. REGION. THERE ARE SUSPICIONS THAT. EARTHQUAKE COULD HAVE POSSIBLY. TRIGGERED AN AVALANCHE OF ICE. AND ROCKS THAT THEN LED TO THOSE. MASSIVE FLASH FLOODS. CREWS ARE ON SCENE AS THEY TRY. TO FIND ANY SURVIVORS BUT. CONDITIONS COULD NOT BE MORE. DIFFICULT PREPARED A LITTLE. WHILE AGO WE SPOKE WITH A. HELICOPTER PILOT OVER THE PHONE. WHO WAS FLYING OVER THAT AREA AT. THE TIME OF THE FLASH FLOOD. HE SAYS WITNESSING THIS DISASTER. UNFOLD WAS TOUGH TO WATCH. >> THIS IS THE MOST HORRENDOUS.

THING I'VE EVER SEEN. EVEN THE GUY FLYING WITH ME 20. YEARS OF EXPERIENCE, IT WAS. DEVASTATING. IT'S HUGE. IT WAS EXACTLY -- YOU CAN SEE. EVERYTHING BEING SWEPT AWAY. >> THE REGION IMPACTED BY THIS. DISASTER HAS EXPERIENCED. FLASH FLOODS IN THE PAST. INCLUDING ONE THAT HAPPENED IN. AUGUST OF LAST YEAR A. WARMING TEMPERATURES OFTEN MELT. THOSE GLACIERS IN THE HIMALAYAS. SENDING WATER AND ROCKS FLOWING. DOWN TO NEARBY VILLAGES. U.S. EMBASSY IN NEPAL SAYS THEY. ARE DEEPLY SADDENED BY THE.

TRAGIC LOSS OF LIFE. THEY ARE WORKING TO ACCOUNT FOR. ANY U.S. CITIZENS IMPACTED BY. THE FLOODING AND REMAIN IN CLOSE. CONTACT WITH AUTHORITIES IN. NEPAL. >> John: JEFF PAUL WITH THE. UPDATE. THANKS.

ONE STANDS A CHANCE LOOKING HOW. QUICKLY THAT COMES OVER AND IT. DEMOLISHES EVERYTHING.

>> John: THE BUSSES IN THE. PARKING LOT. WATCH WHAT HAPPENS. ALL THOSE BUSSES IN THE. PARKING LOT TOSSED AROUND LIKE. THEY WERE MATCHBOX TOYS. IT'S UNBELIEVABLE. >> Jacqui: I WOULD IMAGINE THE. SEARCH IS GOING TO BE VERY. DIFFICULT WITH HOW MUCH. COMPOUNDED RUBBLE THERE IS. THIS IS THE IMAGE THAT TOOK ME. THE MOST. THE HEIGHT OF THAT CLOUD OF. FOREST JUST COMING ACROSS. HOW DO YOU FIND SOMEONE IN THAT? >> John: I SAW AN AERIAL VIEW.

OF THAT SCENE AND THAT BORDER. POST IN CHINA IS SORT OF AT THE. CONFLUENCE OF TWO TRIBUTARIES. IT'S LITERALLY GOT NOTHING ON. THE OTHER SIDE EXCEPT FOR A. RIVER AND THEN IT COMES DOWN. THOSE CANYONS, THOSE VALLE.
