The August eclipse will be "the perfect storm" to collapse Catalan roads

TarragonaThe solar eclipse on August 12, which will last one minute, will be a spectacle of nature but will also entail great risks due to crowds of curious people. Both the public administration, which has already set to work, and citizens will have to organize themselves in advance to prevent the day from becoming a chaotic one. “It will be the perfect storm,” warned Josep Maria Arauzo this morning, a professor of economics at the Universitat Rovira i Virgili (URV) and a specialist in economic structure in Camp de Tarragona, who gave the example of mobile phone service potentially failing. The districts of Lleida and Tarragona, especially in Terres de l'Ebre, will be a privileged place from which to enjoy the spectacle, but the avalanche of visitors requires extreme security measures.

Large crowds are expected on the AP7, which could easily collapse that day, but what is most worrying are the secondary roads, less known to drivers and more difficult for emergency services to manage. The Government has already announced up to 20 observation points (such as El Vendrell, Lleida, Tarragona, or Amposta) that will be prepared to view the eclipse. These are municipalities where a considerable number of people can gather and where it will be easier to manage the massive arrival of tourists. Parking will be provided in these areas, approved glasses will be given to attendees, and emergency services can be deployed. However, many people who want to enjoy the eclipse will go to the chosen locations on their own, which complicates security. It is estimated that, this August, in the areas of Spain from which the eclipse can be seen, there will be a total of ten million more tourists than in a normal summer, and it is very likely that a large part of this crowd will focus on Tarragona, where the sky is usually clearer than in Galicia, which is another of the locations from which the phenomenon can be seen. “There is a risk of illegal camping and there will be bottlenecks, all with the risk of fire that occurs every summer,” explained Arauzo, who predicted that “difficult and unpopular decisions will have to be made,” such as closing access to roads or small towns. “It will be a very important task for the administration to determine where one can pass and where one cannot,” he said.

Faced with this situation, experts are asking to limit mobility as much as possible and recommend that if the astronomical phenomenon can be seen from home, it is best to stay there. Those who are not so lucky can go to the municipalities chosen by the Generalitat, and those who wish to go on their own must take into account that they may encounter blocked roads —the closed accesses will be made public later— or that perhaps the chosen location is not good enough because the eclipse will be around 8:30 PM, shortly before sunset, and it is possible that a mountain may block it. On May 1st, the sun will be in the same position as on August 12th, so it is a good day to check if the chosen location is suitable or not. The days following May 1st will also be valid for carrying out the test.

Losing vision

Another risk that the eclipse will entail is losing vision. “In all eclipses there are people who lose their vision”, warned Pere Romero, ophthalmologist and full professor at the URV. Romero has warned that the only glasses that are not dangerous are the approved ones that have ISO 12312-2. Any alternative will be a bad idea. No type of sunglasses will do, and the strategy of looking at intervals is counterproductive and can be even worse for your health. The risk of burning the central part of the retina is really high. Romero explained that “loss of vision occurs two hours after” looking at the sun and can cause vision problems in both eyes for six months. In some cases, sight can be lost directly, but it mostly returns, yes, after half a year. Romero has warned that young people are the ones at most risk and has asked the public administration to reinforce the ophthalmological emergency service during the days following the eclipse.
