They are two major destructive generators: San Andreas Fault in California and Cascadia Subduction ZO Offshore of North Coast, Oregon, Washington, and British Columbia.
The community often reflects on these dangerous areas such as different agencies.
But what if they have been able to get back to the disasters?
That is a negative possibility described in a new molded research published recently in Journal Geephere.
The authors suggested that, thousands of years, a great earthquake in the Cascadia Subdation Zone immediately followed the great earthquake in northern SanReas Emaureas Faumps.
In 1700, the Cascadia Subduction Zonekukwquake is said to be measured in size 9 Earthquake was overwhelmed, all parts of the Pacific coast were thrown into 5 meters. In the Pacific Northwest, traditional American news were told that the sea and the “boats entered the trees.
This study shows that Cascadadian earthquakes were followed by Northern San andreas from Cape Town to San Francisco, 7.9 largest.

“What San rich earthquakes are most likely to occur after the Cascadian earthquake,” said Jason R. Patton, California Geological Serve and California Geological Serton and the author.
Evidence reflects San-rich error in 1700 for an earthquake within hours to Cascadian earthquakes. “It is possible to be minutes, but we can’t pour it down,” said the leading writer in ApoleOsLoging and Oregon State University and Professor of Marine Geology.
One PUNCH of one earthquake may not be “not only a black black-in-average,” Goldfinger said. “This is, the case, most of the time.
The great economic earthquake of Cascadia is followed by the San Andreas Empartics of the North and Nearly Errors also a period of time between 1425 and 1475; between 1175 and 1225; And about AD 825 years and 475 bc, according to Goldfinger.

The results of the authors’ conclusion is important. Emergency Management has long been afraid of the repetition of 1906 San Francisco earthquakes or 1700 earthquakes of cascadia and tsunami.
Repetition in 1906 earthquakes might be thousands of death, as well as billions of dollars in death, with one estimate.
The 9 earthquake of Cascadia Zover in Cascadadia can cause the Tsunami Wave long-term lengths, destroying 101 and has caused $ 70 billion with damage on top of pugran coast. More than 100 bridges will be lost, power lines are used and the cities of the coastal coast. Citizens could be 15 minutes notice to escape from high soil, and some 10,000 were to perish, according to the previous decade ago. The ports can face great damage.

Confidence, findings in the study are hypotheses. Scientists will not be aware that the great earthquake of the Cascadia causes a quake of the biggest mistakes in San Andreas after the future occurrence, Patton said.
But the results of the study suggest that the great earthquake of the Cascadia area may have northern San Andreas to speed up in larger earthquake minutes until after hours, or after years, some months said.
“Some of the biggest events will get you down the whole world resources trying to answer,” Goldfinger said. “Therefore if you have two of those, you double in that.”
Another important idea of the previous earthquake in northern San Andreas may have begun in Cape Mondocino and San Francisco. Such a situation would bring about the worst inspiration in San Francisco than 1906, when the Epicentter is near the gold gate but moved from town.
The key to the research were investigating earth’s pieces out of scientists from a ship with deeper samples under the sea. Earthquakes that cause underground landings, and leaves deposits called “turmeni” over time.
Usually, scientists can expect earthquakes and lead to a typical pattern – the storm sand caused great earthquakes, and beautiful, as easy, Goldfinger said.
But scientists put for decades.
Only one place on California on the California page – around Noyo Canyon, very closer to San andreas error, but marine samples seem to be down, and the sand samplers. Scientists had no way of explaining, the mystery that was very abusive, “Goldfinger said.
It may take more than 15 years before the potential response saw them.
Under this explanation, good deposits, the silties are first entered from a long way away from the references from Cascadia. Cascadia’s quake was about 50 miles[50 km]from Nobo Canyon, as well as that distance, “and … The first thing to go to calm down,” said Goldfinger.
That was immediately followed by the San Andreas Fault, which brought strong trembling and caused steal coarer sand over the Simpty layout set.
When researchers come up with this possible interpretation, “suddenly, everything understood,” Goldfinger said.
Scientists have received additional evidence in recent years to ensure the existence of Northern San andreas for 1700 errors – there and the time of the Cascadadia Earthquake.
In some cases, there is evidence of severe earthquakes in northern San Andreas after San Francisco in 1700, including indicators located near San Francisco Zoo, Goldfingers, as well as the northern city.
Automatically, another group of scientists use a completely different approach – ring patterns and other latest trees of the Redwood – recent research to eliminate the final earthquake in northern San Andreas before 1900.
That was “good preparation for what we propose,” Goldfinger said.
Earthquakes can cause some earthquakes to prioritize. Scientists believe that size 6.1 Joshua Tree Templor of April 22, 1992, led to the upgrading of the north. Eventually they began in June 28 7.3 Early 7.3 earthquakes for the Mojave quake – it is powerful enough to cause him to move Denver – again, after several earthquake.
Whenever the biggest earthquake happens, the fullness of land surrounding a cracked error is reduced and extended, Patton said. In some areas, the difficulty of earthquakes diminishes; For some, it is increasing – making earthquakes in the area more closely for failing and failing to come up with the other great earthquake.
Goldfinger and Patton were among the authors of the study article published in 2008 at the Bulletin of the Requirin of the Esmologic Society of the lowest San Andreas Faumpis.
