Gorringe Ridge

The Gorringe Bank is about 200 kilometers southwest of Cabo de São Vicente in Portugal in the Atlantic below the sea level lying volcanic mountain with two peaks. The Pico Gettysburg is at its peak about 20 feet below the water surface and is marked with a yellow light buoy as a shoal. The associated with a 40 -kilometer-long, up to 500 meters deep incised ridge summit of Ormonde is a few meters deep under water and is not marked. The two mountains directly attributable region has an area of ​​approximately 9500 square kilometers and is very rugged. The north-west side falls a distance of 38 kilometers around 5000 meters from the south-east side and at 31 kilometers to 4000 meters. Also in the other directions a water depth of about 3000 meters is reached quickly. Some experts, the area is considered to be the most vulnerable region of earthquakes in Europe. One theory here is the epicenter of the earthquake of Lisbon of 1755. In the area of ​​Gorringe Bank is a strong gravity anomaly before.

In 2013, as reported by scientists at Monash University in Melbourne, Australia, that the matter raised by the events in the Gorringe Bank is a subduction zone where the Atlantic seabed 'll swallowed by the Eurasian plate.
