A disturbing report by Algarve based eco-association ASMAA states that the Algarve is at an increased risk of earthquakes due to drilling activity in the search for offshore gas.
"The Algarve’s offshore areas are 'geologically fragile' and substantial gas extraction is now known to initiate earthquakes," according to eco-conservationist Laurinda Seabra.
"In an unstable area such as the sea around the SW coasts of Portugal, where much tension may have been built up since the earthquake of 1755, such earthquakes may trigger a much larger catastrophic earthquake. I suggest that more attention is given to these very important facts," according to expert Eng. Anthonie van den Brink.
