0:00:02 > 0:00:04My name's Steve Backshall...
0:00:06 > 0:00:09..and this is Deadly Pole To Pole.
0:00:09 > 0:00:11Ohh!
0:00:11 > 0:00:13From the top of the world to the bottom...
0:00:13 > 0:00:15Whoa! Ha-ha!
0:00:15 > 0:00:17..deadly places,
0:00:17 > 0:00:18deadly adventures
0:00:18 > 0:00:20and deadly animals.
0:00:21 > 0:00:24And you're coming with me, every step of the way!
0:00:25 > 0:00:27Aaaargh!
0:00:29 > 0:00:34This is Hawaii, the most isolated island chain on Earth.
0:00:34 > 0:00:39It's a place of big waves, big animals and mighty forces of nature.
0:00:39 > 0:00:42It really is a lethal version of paradise.
0:00:43 > 0:00:47Hawaii is a series of volcanic islands in the middle
0:00:47 > 0:00:51of the Pacific Ocean, over 2,000 miles from the United States.
0:00:54 > 0:00:58'The tropical waters around Hawaii are home to marine monsters.'
0:00:59 > 0:01:00Whoa!
0:01:00 > 0:01:03'And I'm here on the hunt for a hot-blooded heavyweight.'
0:01:03 > 0:01:05Wow!
0:01:05 > 0:01:08'Tracking down devils in the moonlight...'
0:01:08 > 0:01:09Look at that!
0:01:09 > 0:01:11Ohhh!
0:01:11 > 0:01:15'..and getting toasted on a giant volcano.'
0:01:15 > 0:01:16Aghhhhh!
0:01:16 > 0:01:20It's on fire, and I'M on fire! Ow!
0:01:26 > 0:01:29Hawaii may be known for its gnarly surfers,
0:01:29 > 0:01:34but we're off in search of a beast that's a master of the open ocean.
0:01:36 > 0:01:38The humpback whale,
0:01:38 > 0:01:40one of the largest creatures on the planet,
0:01:40 > 0:01:43and they're here for a reason.
0:01:43 > 0:01:46The first thing we need to do is to find a whale.
0:01:46 > 0:01:48And that really shouldn't be too hard.
0:01:48 > 0:01:50There are literally hundreds of them here.
0:01:50 > 0:01:53What we'd really like to see is when the males come together
0:01:53 > 0:01:56and start competing for the attention of a female.
0:01:56 > 0:01:59It's known as the heat run, and it's pretty explosive.
0:01:59 > 0:02:01WHALE CALLS
0:02:01 > 0:02:05Humpbacks are normally thought of as gentle giants.
0:02:05 > 0:02:09But at this time of year, around Hawaii, they show their savage side.
0:02:12 > 0:02:16It's the one chance for males and females to partner up.
0:02:19 > 0:02:21Thousands of whales have travelled
0:02:21 > 0:02:25halfway across the globe to find a mate here.
0:02:25 > 0:02:28But the males have to do battle to see who gets the girl.
0:02:30 > 0:02:32And this is the heat run.
0:02:41 > 0:02:45'Our aim is to film a group of gladiatorial whales both above
0:02:45 > 0:02:47'and below the surface.
0:02:47 > 0:02:49'And not get squished in the process.
0:02:51 > 0:02:55'It's going to take a lot of searching to find the right group,
0:02:55 > 0:02:58'and luck to get into the water at the right place at the right time.'
0:03:00 > 0:03:02Ohh! Oh, wow!
0:03:06 > 0:03:09These mega beasts are warming up for action.
0:03:12 > 0:03:15This magnificent behaviour is known as tail slapping,
0:03:15 > 0:03:20for very obvious reasons. The sheer size of the flukes
0:03:20 > 0:03:23on the tail of this animal mean that this sound is going to be
0:03:23 > 0:03:25carried over enormous distances.
0:03:25 > 0:03:27You can hear it now even above the water,
0:03:27 > 0:03:31but underneath the water, it's going to travel further and faster.
0:03:31 > 0:03:34This is almost certainly a way of males communicating with each other.
0:03:34 > 0:03:37And it's probably a sign of aggression.
0:03:40 > 0:03:42'This whale could be issuing a challenge,
0:03:42 > 0:03:44'throwing down the gauntlet.
0:03:44 > 0:03:48'But we need to film the battle that follows.' Whey!
0:03:48 > 0:03:50Oh, my goodness, there it is!
0:03:50 > 0:03:52'So we're working with two whale researchers.
0:03:52 > 0:03:55'Any footage we get will be good data for their studies.'
0:03:55 > 0:03:57CAMERA CLICKS
0:03:57 > 0:03:59It's going to be really important for us
0:03:59 > 0:04:03to listen to what we're hearing from Joe and from Jill.
0:04:03 > 0:04:05They're the real experts in these waters.
0:04:05 > 0:04:09These animals are so big and they're so intent on breeding
0:04:09 > 0:04:12that they could potentially be dangerous to us.
0:04:12 > 0:04:14So we really need to be very, very cautious and careful
0:04:14 > 0:04:16before we think about getting in the water.
0:04:16 > 0:04:19'Without Joe and Jill's knowledge of these whales,
0:04:19 > 0:04:22'we wouldn't see action like this.'
0:04:22 > 0:04:24Whoa!
0:04:24 > 0:04:26Wow!
0:04:26 > 0:04:28Yes!
0:04:28 > 0:04:31Almost completely leaving the water!
0:04:33 > 0:04:35Imagine the force and speed it must take
0:04:35 > 0:04:38to drive an animal like that out of the water.
0:04:40 > 0:04:43When these 40-tonne beasts fight it out,
0:04:43 > 0:04:46the heat run can get seriously dicey.
0:04:49 > 0:04:52We're into the middle of the afternoon on our first day.
0:04:52 > 0:04:55We've seen some incredible behaviour from humpback whales,
0:04:55 > 0:04:57but we haven't yet had our ideal opportunity to jump in
0:04:57 > 0:05:00with whales that are actually competing over a female.
0:05:00 > 0:05:02But we're not giving up on it yet.
0:05:08 > 0:05:12'I'd never seen so many humpbacks in one place, but it's still
0:05:12 > 0:05:15'going to be a challenge to find the right clashing group.'
0:05:17 > 0:05:18Oh!
0:05:22 > 0:05:25All of a sudden, we can see some activity which is definitely
0:05:25 > 0:05:28different from everything we've seen before.
0:05:28 > 0:05:32There are at least three males tailing one female.
0:05:32 > 0:05:34Could be even more than that.
0:05:34 > 0:05:37And this is exactly what we were hoping to find.
0:05:37 > 0:05:40It's a case of the males vying for position,
0:05:40 > 0:05:43battling for their right to be the one that gets to breed.
0:05:45 > 0:05:47Go, go, go!
0:05:47 > 0:05:49Ohh!
0:05:49 > 0:05:50Fabulous!
0:05:57 > 0:05:59It's all kicking off.
0:05:59 > 0:06:03We need to get close to film before they power off into the blue.
0:06:04 > 0:06:06But they're just too quick.
0:06:06 > 0:06:10With their mighty tail flukes, they can even outrun our motorboat,
0:06:10 > 0:06:11let alone me.
0:06:15 > 0:06:18Within seconds, all signs have gone.
0:06:18 > 0:06:20The mighty whales have vanished.
0:06:22 > 0:06:26But there were other speedy shapes zipping along behind them.
0:06:34 > 0:06:38Spinner dolphins - the most acrobatic of all dolphins.
0:06:38 > 0:06:40But not what we're looking for.
0:06:43 > 0:06:46I'm not sure how we managed to miss them.
0:06:46 > 0:06:50We did have a real unexpected surprise though,
0:06:50 > 0:06:52but no sign of humpbacks.
0:06:52 > 0:06:57How five animals of that size, 30-odd tonnes, can just disappear
0:06:57 > 0:07:02and then pop up again, like, 200m off in the distance, is beyond me.
0:07:05 > 0:07:07The same story plays out again
0:07:07 > 0:07:10and again over our two days of searching.
0:07:13 > 0:07:16- Go right! CREW MEMBERS:- Right!
0:07:16 > 0:07:17Go right, Steve!
0:07:19 > 0:07:23And they move so fast! You wouldn't believe that an animal of that
0:07:23 > 0:07:27size could put on such a surge of pace and keep it up as well.
0:07:37 > 0:07:39This is such hard work.
0:07:39 > 0:07:42They are going like the clappers.
0:07:43 > 0:07:45'It's all down to guesswork.
0:07:45 > 0:07:48'Trying to predict which way they'll go
0:07:48 > 0:07:50'and dropping in where we think they'll swim.'
0:07:50 > 0:07:52This is definitely the group we want.
0:07:53 > 0:07:57You can see all of the competitive behaviour from the males.
0:07:57 > 0:07:59Slapping each other with their tails,
0:07:59 > 0:08:02leaping practically on top of each other.
0:08:04 > 0:08:05This is the heat run.
0:08:08 > 0:08:10The action we've been searching for.
0:08:10 > 0:08:14One single female being pursued by scores of fiery suitors.
0:08:17 > 0:08:20Somehow, we have to drop in close enough to film but not
0:08:20 > 0:08:24so close that we get tossed out of the water like rag dolls.
0:08:26 > 0:08:30Once underwater, the scale of these mega beasts is revealed,
0:08:30 > 0:08:33like runaway nuclear submarines.
0:08:38 > 0:08:42From down here, it's clearer to see there are several determined males
0:08:42 > 0:08:45all in pursuit of just one female.
0:08:45 > 0:08:48This is an endurance race like no other.
0:09:01 > 0:09:04They have the largest fins of any animal and use them
0:09:04 > 0:09:06to batter their rivals.
0:09:06 > 0:09:09This is when humpbacks really show their brutal side.
0:09:11 > 0:09:13Whoa!
0:09:16 > 0:09:19Their tail, too, becomes a mighty weapon.
0:09:22 > 0:09:24It's been a titanic spectacle.
0:09:26 > 0:09:29The strongest or most persistent will eventually get the girl,
0:09:29 > 0:09:32but by then, they'll be miles away.
0:09:32 > 0:09:35'And we've been as close as we'd ever want to be
0:09:35 > 0:09:38'to these battling giants.'
0:09:38 > 0:09:40That was what we've been waiting for.
0:09:40 > 0:09:44I lost count of how many whales there were there.
0:09:44 > 0:09:46Maybe six?
0:09:46 > 0:09:51And the female just being gunned down by these outriders.
0:09:51 > 0:09:54Some of them right up close to her, some of them drifting behind,
0:09:54 > 0:09:56jostling for position.
0:09:56 > 0:10:02But they were knocking absolute bells out of each other. It's...
0:10:02 > 0:10:05It's mad. Crazy.
0:10:06 > 0:10:10There is no doubt in my mind that these animals are deadly.
0:10:12 > 0:10:15With drive and determination to find a mate...
0:10:17 > 0:10:19..deceptive speed...
0:10:19 > 0:10:22and surprising aggression,
0:10:22 > 0:10:25a runaway humpback will stop at nothing.
0:10:38 > 0:10:41'We're staying out at sea for our next mission.
0:10:41 > 0:10:44'But this time, for a moonlight dance
0:10:44 > 0:10:46'with one of nature's true devils.'
0:10:54 > 0:10:57It's a very sinister thing, getting into the water when it's dark
0:10:57 > 0:10:59and moody and spooky.
0:10:59 > 0:11:01It feels like something you shouldn't be doing,
0:11:01 > 0:11:03jumping into the sea at night.
0:11:25 > 0:11:30Well, I'm down in the darkness, and I can't see anything as yet.
0:11:43 > 0:11:46Though the water's quite clear,
0:11:46 > 0:11:51you can see that it's filled with what looks like snow.
0:11:51 > 0:11:56And most of this is actually tiny, tiny animals - plankton.
0:11:59 > 0:12:02'And the creature we're looking for feasts on hundreds
0:12:02 > 0:12:05'of thousands of these mini animals every day.'
0:12:13 > 0:12:17I can already make out some strange shapes in the darkness!
0:12:24 > 0:12:25Oh, my goodness!
0:12:31 > 0:12:33Look at THAT!
0:12:39 > 0:12:42I am utterly speechless!
0:12:47 > 0:12:49I didn't expect anything like this!
0:12:53 > 0:12:54Whoa!
0:12:56 > 0:12:58Ha-ha-ha-ha!
0:13:00 > 0:13:03These are manta rays.
0:13:03 > 0:13:08What a phenomenal beast. And they're everywhere!
0:13:10 > 0:13:11I thought we might see...
0:13:13 > 0:13:15..four or five.
0:13:16 > 0:13:18But there must be 30!
0:13:25 > 0:13:28'These sinister-looking animals have been known as sea devils.
0:13:31 > 0:13:34'They get this name from their horn-shaped head fins, which they
0:13:34 > 0:13:37'use to funnel plankton into their cavernous mouths.'
0:13:41 > 0:13:44And the mantas are feasting.
0:13:44 > 0:13:47Oh, my goodness, it nearly took my head off!
0:13:50 > 0:13:56And this isn't phytoplankton, it's not plants, it is zooplankton.
0:13:58 > 0:13:59Tiny baby animals.
0:14:01 > 0:14:03'Thousands of litres of sea water
0:14:03 > 0:14:06'are driven through each manta's mouth each day.
0:14:06 > 0:14:09'The plankton is then filtered through sponge-like tissues
0:14:09 > 0:14:11'called gill rakers.'
0:14:16 > 0:14:19And as they swim towards you,
0:14:19 > 0:14:23you're gazing down into this vast open mouth...
0:14:25 > 0:14:26..as it sucks up food.
0:14:31 > 0:14:34It's extraordinary to think that an animal of this size
0:14:34 > 0:14:37can feast on something this tiny.
0:14:37 > 0:14:41Is there anything that looks more like an alien spaceship
0:14:41 > 0:14:42on the planet?
0:14:45 > 0:14:47If there is, I can't think of it.
0:14:51 > 0:14:53They may be relatives of the sharks,
0:14:53 > 0:14:55but they're utterly harmless to humans.
0:14:58 > 0:15:02Mantas are social animals and have the largest brain of any fish.
0:15:04 > 0:15:06They use their extended pectoral fins to flap,
0:15:06 > 0:15:09fly and glide through the water.
0:15:11 > 0:15:15It's one of the most hypnotic ways of getting about in nature.
0:15:24 > 0:15:29It does seem to be a very easy, very energy-efficient way of moving.
0:15:33 > 0:15:36They just fly through the water.
0:15:36 > 0:15:39They're like an undersea version of Batman.
0:15:44 > 0:15:49Every once in a while, they swim into you and they hit you.
0:15:49 > 0:15:55And they have very much the same skin as their shark cousins.
0:15:57 > 0:16:00One direction, it's very smooth, the other direction,
0:16:00 > 0:16:02it's incredibly sandpaper rough.
0:16:02 > 0:16:05And it feels like it's going to take all your skin off!
0:16:07 > 0:16:10And I guess they're kind of like a flattened shark,
0:16:10 > 0:16:12almost like a pancake version of one.
0:16:16 > 0:16:18Ohhh! Ha-ha-ha-ha!
0:16:20 > 0:16:24They kind of...swim towards you and you can't tell if they're
0:16:24 > 0:16:26going to back out at the last second or not.
0:16:26 > 0:16:29I've been clouted a few times.
0:16:29 > 0:16:32But, I have to admit, I don't really mind.
0:16:32 > 0:16:34This is brilliant! Ha-ha-ha-ha!
0:16:43 > 0:16:47They are sucking up plankton in extraordinary amounts,
0:16:47 > 0:16:49maybe 30 kilos a day.
0:16:52 > 0:16:55If that isn't a display of predatory behaviour,
0:16:55 > 0:16:56then I don't know what is.
0:16:57 > 0:17:00And I think that makes them deadly.
0:17:03 > 0:17:05Deadly and very, very beautiful.
0:17:08 > 0:17:12Some mantas can reach 7m in wingspan.
0:17:12 > 0:17:15With beautiful and efficient underwater flight,
0:17:15 > 0:17:19hoovering up to 30kg of baby animals each day...
0:17:20 > 0:17:24..mantas are giant, gentle gymnasts of the ocean.
0:17:36 > 0:17:39But in Hawaii, it's not just animals that are deadly.
0:17:39 > 0:17:41The very landscape can be, too.
0:17:43 > 0:17:47Hawaii is a volcano hotspot, literally.
0:17:51 > 0:17:55It's home to the largest and most active volcanoes on Earth.
0:18:06 > 0:18:09This is nature's most powerful force.
0:18:09 > 0:18:12Molten rock exploding from the depths of the Earth,
0:18:12 > 0:18:17scalding, scorching, burning and vaporising everything in its path.
0:18:19 > 0:18:23In terms of wielding destruction on a mighty scale,
0:18:23 > 0:18:25volcanoes really have no equal.
0:18:25 > 0:18:28They're probably the deadliest thing we've ever featured.
0:18:28 > 0:18:30But to really appreciate how they work,
0:18:30 > 0:18:33you need to get close enough to really feel the burn.
0:18:33 > 0:18:36And there's a place up the coast where we can do just that.
0:18:50 > 0:18:52Ohhh, wow!
0:18:55 > 0:18:57That is unreal.
0:19:01 > 0:19:04I've been working with deadly animals for most of my life,
0:19:04 > 0:19:06and they don't really frighten me.
0:19:06 > 0:19:09But there's something about this that really puts the hackles up
0:19:09 > 0:19:11on the back of my neck.
0:19:13 > 0:19:16Wo-o-o-ow!
0:19:18 > 0:19:20There are very few places on the planet where you can see
0:19:20 > 0:19:22something like this.
0:19:22 > 0:19:26Lava pouring molten rock directly into the sea.
0:19:27 > 0:19:32I mean, can you imagine how hot it has to be to melt rock,
0:19:32 > 0:19:35to turn rock into liquid so it's like treacle?
0:19:38 > 0:19:42'When the lava hits the ocean, the water instantly boils
0:19:42 > 0:19:45'and sends up plumes of superheated steam into the air.'
0:19:46 > 0:19:50Wow. 'It's likely that this is what it would've looked like
0:19:50 > 0:19:52'at the birth of planet Earth.'
0:19:53 > 0:19:57What we're looking at here is Hawaii being born.
0:19:57 > 0:20:01This is new rock coming to life, forming the very island itself.
0:20:02 > 0:20:04It is a true inferno.
0:20:06 > 0:20:10It's one of the most exciting but possibly the most chilling
0:20:10 > 0:20:12and overpowering things I think I've ever seen.
0:20:12 > 0:20:16'All of Hawaii's islands were formed by volcanoes like this.'
0:20:18 > 0:20:23Over millions of years, layers of lava from beneath the Earth's crust
0:20:23 > 0:20:25have formed this island chain.
0:20:29 > 0:20:31And it's still happening now.
0:20:31 > 0:20:35Several miles inland is an active, erupting volcanic caldera.
0:20:36 > 0:20:39But the only way to approach is by air.
0:20:52 > 0:20:57On our way to the source, the lava's destructive power is clear.
0:20:57 > 0:20:59Wow!
0:21:00 > 0:21:05You can really see here where the trees meet this
0:21:05 > 0:21:08morass of black rock.
0:21:08 > 0:21:12There, it's alive. You can see the trees are singed and black.
0:21:12 > 0:21:13But here, beneath me,
0:21:13 > 0:21:18everything's been destroyed by this unstoppable river of lava.
0:21:21 > 0:21:25The blackness, the devastation, just goes on for miles,
0:21:25 > 0:21:27as far as the eye can see.
0:21:29 > 0:21:33It's like flying over the surface of some alien planet.
0:21:39 > 0:21:40That is stunning.
0:21:45 > 0:21:47Ohhh!
0:21:48 > 0:21:54You could see where all the molten rock is coming to the surface.
0:21:54 > 0:21:55Can you get a shot of that, Luke?
0:21:58 > 0:22:03You can see the perfect round crater where all of this molten rock
0:22:03 > 0:22:06has come up from the hotspot beneath the crust
0:22:06 > 0:22:08and has flown up to the surface.
0:22:08 > 0:22:12From here, the lava is flowing in lava tubes,
0:22:12 > 0:22:15almost like tunnels or caves, right down to the coast.
0:22:16 > 0:22:18And I can feel the heat.
0:22:18 > 0:22:21Even with the rotors above us blowing it away,
0:22:21 > 0:22:23it's still coming up like a furnace towards us.
0:22:26 > 0:22:30It's a magnificent sight, but really actually quite frightening.
0:22:31 > 0:22:33OK, the next thing we want to do
0:22:33 > 0:22:36is to land on some of this black pavement.
0:22:36 > 0:22:39I want to really feel it beneath my toes.
0:22:44 > 0:22:47We'll be taking great care where we walk,
0:22:47 > 0:22:51but I'm hoping to find out quite how hot this lava really is.
0:22:54 > 0:22:58It's kind of a strange sensation, walking along with the rock
0:22:58 > 0:23:01underneath your foot crackling and popping.
0:23:01 > 0:23:04It's almost like walking on rice crispies.
0:23:04 > 0:23:08'Below my feet are new rocks made from cooled lava.
0:23:08 > 0:23:12'It's hard, dark, moulded like cast-iron.
0:23:12 > 0:23:15'But what we really want is some fresh, still liquid lava.
0:23:18 > 0:23:23'This heat-sensitive camera will help us pinpoint where to head.
0:23:23 > 0:23:26'The camera shows a river of lava on the horizon flowing just
0:23:26 > 0:23:28'beneath the surface.
0:23:28 > 0:23:32'The rocks might look black and cold, but on this screen,
0:23:32 > 0:23:35'we can see that they're actually scorching.
0:23:35 > 0:23:39'So hot that it's maxed out our camera at 550 degrees Centigrade.
0:23:39 > 0:23:43'But I'm pretty sure the lava's hotter than that.'
0:23:45 > 0:23:49We're definitely getting closer to our hotspot.
0:23:50 > 0:23:56All of a sudden, I've just been hit by a wall of heat.
0:23:58 > 0:24:03And there is our first explosion of lava.
0:24:03 > 0:24:06Look at that, flooding out.
0:24:06 > 0:24:10Now, somehow, I've got to figure out a way to get close enough to that
0:24:10 > 0:24:12to measure out quite how hot it is.
0:24:14 > 0:24:16And I'm guessing it's pretty hot.
0:24:16 > 0:24:19I don't think I want to get any closer than this.
0:24:20 > 0:24:22So this is a unique opportunity
0:24:22 > 0:24:25to actually measure how hot this rock really is.
0:24:25 > 0:24:29I've got here what is essentially a very, very expensive,
0:24:29 > 0:24:31very, very tough thermometer.
0:24:31 > 0:24:34So I'm going to go in, whack a hole in this hot lava here,
0:24:34 > 0:24:36and just place the thermometer inside.
0:24:36 > 0:24:39And Simon the sound recordist here is going to be standing
0:24:39 > 0:24:42back at a safe distance to record how hot it is.
0:24:42 > 0:24:46The only safety equipment I've really got is a pair of oven gloves.
0:24:46 > 0:24:47And I have to be honest -
0:24:47 > 0:24:50at the moment, it really doesn't feel like enough.
0:24:57 > 0:24:59Pffft!
0:25:02 > 0:25:06Erm, I am totally out of my comfort zone here!
0:25:06 > 0:25:12I have to admit, I'm a bit scared! I've come over all completely wussy.
0:25:12 > 0:25:15Erm, but I guess I should give it a go.
0:25:15 > 0:25:17OK.
0:25:19 > 0:25:21- Oh...- Oh!
0:25:22 > 0:25:27- Yeah.- Right, that's really, really hot. Erm, right, come on, Backshall.
0:25:32 > 0:25:34Agh!
0:25:36 > 0:25:38Agh!
0:25:40 > 0:25:42Have you got a reading?
0:25:42 > 0:25:46Er, 29... Whoa! 106...
0:25:46 > 0:25:49Arghhhh!
0:25:49 > 0:25:50Did you see how hot that went?
0:25:50 > 0:25:54Yeah, just, I mean... It was, like, 29 and it jumped up to over 1,000.
0:25:54 > 0:25:57- Just went "boom".- Wow.
0:25:58 > 0:26:02So 1,136 degrees C is pretty intense,
0:26:02 > 0:26:06but it's very difficult to get your head around quite how hot that is.
0:26:06 > 0:26:10Luckily, I do have a way of putting it into real familiar human terms.
0:26:10 > 0:26:12We're going to make toast.
0:26:23 > 0:26:25Can anyone see? Is it going brown?
0:26:30 > 0:26:32Yeah, that's definitely the one side done.
0:26:32 > 0:26:34Aghhhh!
0:26:36 > 0:26:39Hey! It's on fire, and I'm on fire!
0:26:39 > 0:26:41Ow!
0:26:42 > 0:26:46Well...it's a little bit overdone.
0:26:47 > 0:26:52I don't usually have my toast quite that charred.
0:26:57 > 0:26:58Still tastes pretty good, though.
0:27:07 > 0:27:10Hawaii has one of the most active volcanoes on Earth,
0:27:10 > 0:27:14reaching temperatures of over 1,000 degrees Centigrade
0:27:14 > 0:27:17and lava flows that tear across the landscape.
0:27:18 > 0:27:22The volcanoes of Hawaii are a true destructive force.
0:27:27 > 0:27:31Join me next time as I continue my journey on Deadly Pole To Pole.
