The canyons of the Capitol and the seashores of Fernando de Noronha function a mannequin for the principles
Chapter: Geologists will create the primary tourism threat laws
“We go to the areas to sign the dangers, as a result of every location has a unique state of affairs and actuality, as within the case of the Capitólio canyons, that are totally different from the cliffs of Fernando de Noronha, for instance,” says president Febrageo. , who additionally led the primary group of geologists to go to and assess the Furnas canyons after the accident.
“With this set of conditions, we can have a step-by-step imaginative and prescient of what must be achieved in every space, we’ll attain a consensus and set up normal norms, which may change into state or federal laws,” provides the researcher and grasp in Geotechnics and Geology.Environmental Science on the State College of São Paulo (Unesp).

By the top of 2022, Reis expects the workforce’s evaluations of visited factors to debate with consultants and set requirements. Subsequent, areas of waterfalls, caves and mountains can be visited.
“The adoption of particular guidelines for the administration of geological dangers in vacationer areas is crucial, particularly as a result of development of nature and journey tourism in Brazil. I can say that the Capitólio accident helped velocity up the method”, explains the knowledgeable. .
One other geologist, Joana Sanchez, one of many few specialists working with structural geology and geotourism in Brazil, additionally shares Reis’ concept.

“The accident within the Capitólio canyons shone a light-weight all through Brazil on the connection between geological threat and tourism,” says Joana, professor on the Federal College of Goiás (UFG) and member of the workforce of geologists getting ready the requirements. “We all know that the reason for the autumn of the wall was pure, however as it’s, it can not proceed. It’s essential to create the regulation of nature-related tourism websites, which attain 90% on the nationwide territory. , to keep away from predatory tourism and different tragedies,” says the geologist, who additionally participated within the first technical assessments of the Furnas canyons after the accident in January.
Shortly after the autumn of the Capitólio wall, the Ministry of Tourism raised the variety of vacationer locations which can be liable to geological occasions in Brazil (see under). By means of the measure, the federal government intends to take motion to forestall accidents.
The variety of areas of imminent geological threat in Brazil, in keeping with a survey by the Ministry of Tourism. The areas embrace the Chapada dos Veadeiros Nationwide Park (Goiás) and the Xingó (Sergipe) and Poti (Piauí) canyons.
The one regulation in pressure on the matter (Legislation 12.608/2012), which establishes the Nationwide Civil Protection and Safety Coverage, requires municipalities and States to handle Dangers and Disasters, in addition to their accountability in any accidents. However the laws solely offers with threat zones in city areas, and never with vacationer landscapes, as Febrageo warned shortly after the tragedy within the Furnas canyons.
On the time, Febrageo additionally requested the federal authorities for funding in measures and management of pure dangers in Brazil, because the nationwide territory is wealthy in vacationer points of interest associated to geology, resembling parks, caves, mountains, waterfalls, canyons, cliffs and even seashores . The massive downside is that many of those areas do not need a administration plan or have one thing incomplete. Subsequently, the class defends the pressing updating of the regulation.
Geologists have already warned about this downside, particularly after the accidents in pure points of interest on the finish of 2021, such because the collapse of the collapse Altinópolis (SP), the place 9 instructors and civilian firefighters had been buried and just one particular person survived.
In keeping with Joana, the workforce of 9 geologists who labored in Capitólio has already carried out three evaluations of the Furnas canyons, mapping 5 hazard factors, two of which current an imminent threat of falling.
To hold out this work, the canyons had been closed on the day of the accident, being partially launched solely on the finish of March. From the visits and assessments, technical stories had been drawn up highlighting the speedy measures and enhancements to be carried out by the Metropolis Corridor of the Metropolis of Capitólio to permit the attraction to be visited safely.
Adopted since March, the principle measures included the day by day analysis of the canyons by a geologist, the banning of the realm liable to collapse and the set up of rock retention, that are already utilized in civil building, however not for tourism functions and on the partitions, as will do on the Capitol. The retaining parts are made from metal mesh and have to be put in on strong rocks inside one yr.
Furnas Canyons can have an unprecedented metal containment undertaking in 5 hazard factors detected within the geological evaluation (in enlarged element, see the containment mannequin that can be utilized within the Capitólio). The rock formation on this area in southern Minas Gerais dates again 600 million years, having been fashioned within the Proterozoic period, with a predominance of quartzite interspersed with shale.
The realm of canyons open to the general public is secure, the geologist says
After the accident, security grew to become one of many important considerations for anybody planning to go to the Furnas Canyons in Capitólio. Geologist Joana Sanchez says the positioning now has a excessive stage of security with measures already in place since late March.
“The protection index at this time is far larger than the vacationer imagines. I calculated how far individuals could possibly be hit with rock shards if a block fell. Our work necessitated the day by day geological analysis of the canyons, with the geologist having the ability. to shut them”, says Joana.
The workforce of geologists also needs to conduct new assessments at three different rock formation websites within the Capitólio area: Vale dos Tucanos, Cascatinha and Cabrito.
Regardless of realizing the Furnas Canyons since 2005, when she carried out geological mapping of the positioning, Joana nonetheless remembers what her go to to the attraction was like instantly after the accident.
“The sensation of being the primary workforce to enter the canyons after the tragedy was horrible. All of us remained silent and noticed the scar on the wall. years and in addition recognized that there was a misuse of the positioning, however there isn’t a strategy to say that this was the figuring out reason for the autumn.”
The knowledgeable warns that the tragedy may have been prevented if, on the time, there had been visits and technical and geological assessments on the spot. On the time of the accident, Febrageo defined that areas of weak spot within the wall facilitated rock detachment, noting that rains normally trigger the sort of motion. One other excessive level was the water stage variation skilled by many Brazilian reservoirs in recent times, which additionally accelerated erosive processes and block displacement.
