Terramoto

Ruínas da Sé de LisboaNo dia em que o DNA (DN) escreve sobre o terramoto de 1755, lembro a notícia da Reuters de alguns dias atrás:
"Exactly 250 years after one of the world's most devastating quakes transformed regal Lisbon into a ghost town, experts from around the world will gather to find a prologue for the future.

The earthquake that hit Lisbon on November 1, 1755, rang Paris' church bells and triggered a tsunami from Norway to North America. It sent shockwaves through Enlightenment Europe, changing forever the way earthquakes were perceived and handled.

"We have to call attention to the authorities and the population in general that this past event, this terrible event, may come again," said Carlos Sousa Oliveira, president of the Portuguese Society for Earthquake Engineering. "We don't know when. It might not be as strong. But we have to prepare to face it."
(...) "People living in Portugal have no idea of the risk. They are not aware of the risk because earthquakes have a long return period, meaning they can take hundreds of years to happen again," said Alfredo Campos Costa, an earthquake engineer working in seismic risk assessment research."
