How nature creates the big waves at Nazaré? There is a sleeping giant! When he wakes up, he shoots waves of 30 meters (almost a 100ft)! Right in front of Nazaré beach, often serene and inviting for a swim, The cause of this hazard zone is below the water. That was sunk in the depths of the Nazaré canyon - event reported by elderly people who saw. Since old times, the surrounding area of Nazaré has always been feared by fishermen due to the strong sea. Nazaré North Canyon generates giant wave for Garret McNamara in 2015, Nazaré North Canyon Geography - image from blog Mesozoico Nazaré North Canyon seen from Satellite - image from Google Maps It might be related with the Nazaré fault, a fracture zone with movements that can cause earthquakes. The origin of the Canyon is still shrouded in mystery, because it belongs to a complex geological area. It is 227km long and 5 Km maximum depth, with several steep slopes. The Nazaré North Canyon is one of the largest submarine canyons in the World, a giant hole in the bottom of the sea! Sometimes in a favorable way, like the big Atlantic Ocean swells, the collision of two waves directions, the wind, the tides, the sea currents and sea floor. The Nazaré North Canyon is a underwater canyon and the main responsible for the generation of the big waves at Praia do Norte - Nazaré - Portugal, in conjunction with other nature elements, The ebb and flow of waves and tides are the life force of our world ocean.Why are waves so big in Nazaré? Nazaré North Canyon with transparent sea - image from Instituto Hidrográfico Waves caused by the gravitational pull of the moon and the sun are called tides. Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. The cause of tsunamis are not related to tide information at all but can occur in any tidal state. It is a common misconception that a tidal wave is also a tsunami. These waves are tides or, in other words, tidal waves. The gravitational pull of the sun and moon on the earth also causes waves. These waves roll upon the shore like a massive sea level rise and can reach far distances inland. Storm surge and tsunamis are not the types of waves you imagine crashing down on the shore. ![]() These very long waves are called tsunamis. Other hazardous waves can be caused by underwater disturbances that displace large amounts of water quickly such as earthquakes, landslides, or volcanic eruptions. ![]() The strong winds and pressure from this type of severe storm causes storm surge, a series of long waves that are created far from shore in deeper water and intensify as they move closer to land. More potentially hazardous waves can be caused by severe weather, like a hurricane. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. These types of waves are found globally across the open ocean and along the coast. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are created by energy passing through water, causing it to move in a circular motion. Whether observing from the beach or a boat, we expect to see waves on the horizon.
