alexandr fun humble our series on tomorrow today. we want to see what he saw to experience what drove him. but journeys through latin america following the footsteps of the great scientist. our next stop the avenues i'm ok no just in the ecuadorian and. to morrow to do it next on g.w. . good shape i don't have time for this now i have to work we never really have enough time stress is not good for you it's not good for you. sure balcony escaping hamster wheel.

and other time management help us lead healthier lives. in 60 minutes w. . the world is doing or soon. norm's could sastre views among the problems. of. the global $3000.00 talks would seem of british researchers to take a more optimistic view. the world is not always a good point but it's much much better than it was. is the world really getting better. a global $3000.00 special reports. starts august 19th sunday to.

if. you're watching tomorrow today the science show on t.w. coming up. stage 2 in the footsteps of alexander from home bites our reporter heads to ecuador's ave of the volcano. we visit the lens natural history museum where everything from dinosaurs to the mold spines on display. and finally we get under your skin to find out how your body reacts to tattoo ink come to the show. and we kick off with a dispatch from our reporter christiane home on. to mark the 250th birthday of alexander from home but christiane traveled to ecuador peru and colombia 3 countries that the great naturalist explored during his expedition to

the americas. part 2 of the trip takes us to the volcanoes of ecuador. the entire planet to work quito is a single hearth the subterranean fire breaks forth you know from one of these openings now from another. that is how alexander for recall use an expedition through the andes in his book the use of nature in it you know to the naturalistic explorer travelled to ecuador to study the honest active volcanoes on the planet and we are following in his footsteps. they were more afraid of the pork else.

surely they think this guy is crazy i'll try to go through to work with. him or what's fascinating about this site plan. it's a good thing that she decided to do that in this country because they don't have a description. that's key made or can count on this person's. gold hauled to dozens of measuring instruments with him up to the crater of the chincha he wanted to find him perigal evidence that volcano has were connected underground and that eruptions could create mountain ranges now basic knowledge for a vulcanologists like but we see a lot among scientists have determined that the kitchen counter complex is more than a 1000000 years old it's youngest crater was torn out of the mountain range by a gigantic eruption 1000 years ago as the researchers thermal imaging cameras shows

which in show is a very much alive today. i come to something like. 10 floors with a server camera telling us it's still an active volcano and that activity called from the cube but it's there and all the rain i just come inside is. able to work and then. explosives after because the pressure is increase and the crater inside the dome and then you could have structures as i would have kept me for. $73.00 volcanoes more than a dozen of them still active all crowded together in a stretch of less than 200 kilometers. called this unique mountain chain the avenue and. the volcano house no where else in the world other so many volcanoes in such

a small space millions of people in ecuador live under the constant threat of an eruption. it's a threat monitored by scientists at the geophysical institute in quito. for all the technical advances since one boat's day precise forecasts remain elusive but the team is able to closely observe activities inside the volcano. from temperature fluctuations to expanding magma chambers and increased gas emissions and he changes could be an indication of an imminent eruption. in the here is the status report from the refuge the volcano is completely submerged in the clouds not possible to observe any emissions of gas over.

the well scott rubio is the one man patrol team on cotopaxi one of the most active volcanoes in the ecuadorian andes the volcano is under permanent surveillance. bunkered also as he's known up here at the mountain refuge is not easily shaken minor tremors inside the crater are far from the course and often felt in his lodge . the. interruption would give us no more than 5 minutes to respond up here on cotopaxi if the volcano gives us enough time we follow a strict evacuation plan but if not i'll just take my place in the front row to watch this magnificent natural spectacle and then goodbye i'm not afraid. to hike across the barren landscape at the foot of counter boxing we're walking

over what were once deep gorges filled in by the countless tons of mud and debris that has swept through here over the course of millennia. 23456 different layers. and maybe the last one the one and close to the top is the one that was producing during the $877.00 are often the last to be corruption and could actually work in a much flow it's produced that when. they were. having an eruption and delay sure a lot more 6000 meters and then you can even imagine the potential energy when the water start to probe down and finally after descending 345 even more

kilometers from the top of the work i know we have these deposits but our lives from. the powerful volcanic mudflows can reach speeds of up to 60 kilometers per hour destroying everything in their path the last.
