It seemed very dangerous for a few moments, but no-one has been injured in the end. Supporters of FC Porto were asked to leave the north stand in Estoril after serious cracks were found.

Yesterday's football game between Praia Estoril and FC Porto only lasted 45 minuted. During the break supporters of FC Porto, occupying the north end, were asked to enter the field in an evacuation of this part of Estádio António Coimbra da Mota.

While no-one was injured during the evacuation, it may have been a dangerous 45 minutes indeed. Serious cracks in the floor, walls and primary support columns of the north end were noticed in the central part of the north end.

After talks between the clubs, league and safety personnel it was decided the game should be postponed as there was no telling what extent of damage could be expected.

The disturbing findings follow Monday's earthquake in southern Portugal. Its epicenter was located some 127 km east of the Estoril stadium. In Estoril and Lisbon the 4.6-point shakes were only slightly noticable, though some cracks in buildings were observed.

That said, Porto supporters from Dragao & Tripeiro website rightly notice that the pre-game evaluation of the stadium may have not been too thorough if such big issues were missed.

Ironically, the north stand is the most modern one at the Estoril stadium. It was built only in 2014 and is the latest addition, one which raised capacity from 5,000 to 8,000 seats.
