Major earthquake ‘certain’ to hit Southern California, study says

‘No getting out of this’: Major earthquake ‘certain’ to hit Southern California, study says

It is simply a matter of time before a major earthquake hits Southern California, according to a new study by the US Geological Survey (USGS), which examined patterns of historic quakes. The only question is how long it will be before the ‘Big One’ strikes.
The study – the most extensive of its kind – examined a section of the San Andreas fault that runs along Interstate 5, near Frazier Mountain in northeast Kern County.
“One of the reasons why this location is of importance is because in Southern California, the Big Bend, Carrizo, and Mojave sections of the San Andreas Fault accommodate 50-70% of plate motion. This means that the seismic hazard is high,” according to Temblor. 
To understand the size and likelihood of future earthquakes striking the area, the researchers looked into the past, by digging more than 30 trenches to trace ancient temblors.
“To get 1,200 years of records, we have to do lots of excavations and go quite deep,” said the study’s lead author, USGS research geologist Kate Scharer, as quoted by the Los Angeles Times.
Scharer and her team found 10 major earthquakes over a 1,000-year period. They were able to date the temblors by examining charcoal and plant remains found at each horizon.
The most common magnitude found at the site was 7.5.
A 7.9 earthquake in 1857 – the last major temblor to strike – was so powerful that it caused the soil to liquefy and trees to sink and uproot. The shaking lasted between one and three minutes.
Since then, land on either side of the fault has been pushing against the other at a rate of more than 1in per year, accumulating energy which will be suddenly released in a major earthquake that would move land along the fault line by many feet.
A repeat of the 1857 quake could move the land as much as 20ft, damage aqueducts that ferry water into Southern California from the north, disrupt transmission lines, and damage Interstate 5.
Although the researchers noted that a big earthquake is certain, they couldn’t predict when it will happen because they “don’t happen like clockwork.”
For instance, while there was once a gap of just 20 years between two temblors, another pair saw a gap of 200 years between them.
The average interval between quakes was found to be approximately 100 years, meaning the gap separating today from the 1857 earthquake is already 60 years more than the average.
“Longer gaps have happened in the past, but we know they always do culminate in a large earthquake. There’s no getting out of this,” Scharer said.
She went on to urge similar studies to take place so that scientists can gain a greater understanding of the San Andreas Fault, in order to “properly design infrastructure, like highways, water, and power lines, so that it can survive the next earthquake.”
The San Andreas Fault extends roughly 1,300km (800 miles) through California. It has three segments, each with a varying degree of earthquake risk. The most significant is the southern segment, which passes within about 56km (35 miles) of Los Angeles.

A series of small quakes have occurred at Mount Hood, Oregon, USA

Mount Hood is a potentially active stratovolcano in the Cascade Volcanic Arc of northern Oregon. It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States. It is located about 50 miles (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties. In addition to being Oregon’s highest mountain, it is one of the loftiest mountains in the nation based on its prominence.
The height assigned to Mount Hood’s snow-covered peak has varied over its history. Modern sources point to three different heights: 11,249 feet (3,429 m), a 1991 adjustment of a 1986 measurement by the U.S. National Geodetic Survey (NGS),[1] 11,240 feet (3,426 m) based on a 1993 scientific expedition,[6] and 11,239 feet (3,426 m)[7] of slightly older origin. The peak is home to 12 named glaciers and snowfields. It is the highest point in Oregon and the fourth highest in the Cascade Range.[8] Mount Hood is considered the Oregon volcano most likely to erupt,[9] though based on its history, an explosive eruption is unlikely. Still, the odds of an eruption in the next 30 years are estimated at between 3 and 7 percent, so the U.S. Geological Survey (USGS) characterizes it as “potentially active”, but the mountain is informally considered dormant.

I have tweeted USGS & EMSC the importance of the sudden quakes in the Mount Hood area and must take this seriously as a precaution
