The San Andreas fault is about to crack – here's what will happen when it does
For each of these plate boundaries you are responsible for knowing: exists in California, where the Pacific Plate is sliding past the North American plate. Both plates are moving in an approximately northerly direction but the Pacific plate is moving faster than its North American counterpart. Take a tour of the San Andreas Fault in California and see where the In this case, it's where the Pacific Plate and the North American Plate come together. Most of them are located around the town of Desert Hot Springs.
How many tectonic plates are in the Ring of Fire? Professor Cummins said the distinction between a major and minor plate is determined by its size. A hot spot is something that can cause a plate to split in two.
For more than six years since a deadly earthquake struck Christchurch in Februarythe city's iconic cathedral sat in ruins in the city center.

New Zealand is one of the countries that sits within the Pacific Ring of Fire. What is a lahar? They occur typically when a landscape has been covered by loose volcanic material and they pick up material as they travel, causing destruction to whatever is in its path.
An Indonesian man looks at the huge river forged by the flow of lahar from Mount Merapi, in Java in The Aleutians are the most northern part of the pacific Ring of Fire. They are an island chain in Alaska that consists of more than small volcanic islands. These form an arc in the northern Pacific Ocean which stretches from the Alaskan Peninsula to far eastern Russia.
The East Pacific Rise Photo shows the eruption of Wolf volcano, at Isabela island, Galapagos, on 25 Mayhome to the only population of pink iguanas in the world. It stretches from the coast of Central America to South America and is home to submarine volcanoes, islands, trenches, and hydrothermal vents.Plate Tectonic Evolution of North America - Scotese Animation
One of the most famous locations is the Black Smokers near the Galapagos Islands off the South American west coast, considered the first hydrothermal vents discovered on Earth. This is the most famous transform boundary see above in the world, the San Andreas Fault is found along the south west coast of California in the United States.
It slices the area in two from Cape Mendocino to the Mexican border. Where fire meets ice at the most active volcano in Antarctica. Mount Erebus sits on Ross Island, a hot spot in Antarctica for volcanoes. The volcano sits on the Australian Plate, above the Pacific Plate that subducts beneath it. Every year Ruapehu experiences eruptions. Fortunately these are mostly minor but major eruptions do occur every 50 years or so. In an eruption of Krakatoa almost destroyed the original Krakatoa island entirely.
Fuji, Japan's tallest mountain, covered with a thin layer of snow on October 16, Major Ring of Fire catastrophes 08 10 Some major cataclysmic events have happened within the Pacific Ring of Fire since the s. More recently we saw the quakes in Japan and New Zealand and the devastating quake and tsunami in the Indian Ocean in Helens roars to life in this Oct.
The plume was estimated to be 50, feet. Are we crazy to live near volcanoes? Even though eruptions are difficult to predict, Professor Cummins said that many communities are able to manage the risks when it comes to residential proximity.
Residents on edge as Mexican volcano spews lava and ash after earthquake September Thee continent has many volcanoes, majority of which are not active. The only known active volcano on the Australian mainland is Mount Gambier in South Australia, which is said to have erupted as little as years ago, however the likelihood of another eruption any time soon is considered low.
What Happens Where Tectonic Plates Meet?
Australia also has a low earthquake risk, however Professor Cummins warned low risk also meant low tolerance and preparedness for an earthquake event. Both plates are moving in an approximately northerly direction but the Pacific plate is moving faster than its North American counterpart, meaning that stresses between the plates are constantly building up. Insome of these stresses were catastrophically released in the San Francisco Bay area in a 7.
So just how big could this potential earthquake be and is it possible that the destruction demonstrated in the film San Andreas could actually come to fruition?
Fiction … or fact? In short, Californians will be reasonably pleased with the answers to these questions.
Caribbean Plate - Wikipedia
In the film, the San Andreas fault produces an earthquake with a magnitude of 9. While not unheard of globally, earthquakes of this size are generally confined to regions of the earth where subduction — where one tectonic plate is being forced below another — is happening, for example in Chile and Japan.
The tectonic situation in California is different.
Here, two plates are sliding past each other. As such, recent predictions limit the possible maximum earthquake magnitude along the San Andreas fault system to 8. While magnitudes of 7. Obviously, however, be it a 7. For example, the San Andreas fault is not beneath the ocean and as such, any slippage along it could not displace water to the extent that a tsunami would be generated.

The opening up of a massive chasm is also from the land of fantasy, as the plates are sliding relative to each other, not away from each other. Map of the San Andreas Fault, showing relative motion.
