MOVEMENT - RISING & SINKING on the San Andreas Fault

'Seismic strain': Land around the San Andreas fault is rising and sinking.
Rong-Gong Lin II
For the first time, scientists have produced a computer image showing huge sections of California rising and sinking around the San Andreas fault. 
The vertical movement is the result of seismic strain that will be ultimately released in a large earthquake.

The San Andreas fault is California’s longest earthquake fault, and one of the state’s most dangerous. Scientists have long expected that parts of California are rising — and other parts sinking — around the fault in a way that is ongoing, very subtle and extremely slow.
Such vertical movement makes a lot of sense. California sits on the border of two gigantic tectonic plates — the Pacific and North American — that are constantly grinding past each other. 
Once there is a major event, all of that energy gets released.— Sam Howell
But actually observing how California’s landscape is rising and falling from seismic strain has been an elusive goal, until now.
In a study published in the journal Nature Geoscience on Monday, scientists found that much of the Los Angeles Basin, Orange County, San Diego County and the Bakersfield area are sinking 2 to 3 millimeters a year — a couple of penny-widths annually. By contrast, Santa Barbara and San Luis Obispo counties, and a large portion of San Bernardino County, are rising at the same rate. 
Take a look at the image below. The areas in red are rising, while the areas in blue are sinking.

In this image of Southern California, red areas are rising at a rate of a couple of penny-widths a year, while blue areas are sinking. The area closest to the San Andreas fault — seen in white — is not rising or sinking, and will remain locked until a large earthquake hits.

The areas closest to the San Andreas fault, however, remain locked in place. When the next big earthquake strikes, the different parts of Southern California will lurch back to the same level.

“Once there is a major event, all of that energy gets released,” said Sam Howell, a doctoral candidate in geophysics at the University of Hawaii at Manoa and the lead author of the report.


San Andreas movement called significant
Using new techniques, scientists have confirmed there is significant movement along parts of the San Andreas fault.

The region of the San Andreas fault between Monterey County and Imperial County hasn’t moved in a significant way in more than 150 years, and other parts of the fault have been accumulating stress for more than 300 years.

The last big earthquake on the southern San Andreas fault, a magnitude 7.9 temblor, ruptured from Monterey County through Los Angeles County in 1857. Further south, the section of the San Andreas between San Bernardino County and Imperial County hasn’t ruptured in a major way since about 1690.
It’s pretty much impossible to say when the next one will happen.— Sam Howell
Howell said the time span for a large rupture on the southern San Andreas is, on average, once every 150 years or so. But the actual interval can vary over the centuries, and that’s why it’s hard to say exactly when the next big one will hit.
Howell said a better understanding of how California is being warped as a result of this accumulating seismic strain is helping scientists “understand more about how the fault is behaving and the effect it’s going to have in the surrounding region.”
The study, however, isn’t expected to help scientists suddenly predict the precise time and location of the next devastating quake. “It’s pretty much impossible to say when the next one will happen,” Howell said.
GPS data provided the raw information of how the earth is moving subtly from seismic pressure. 
Howell said it has been easy for scientists to see how California was moving in north, south, east and west directions, but it was much harder to show how the state was moving vertically due to seismic forces.

The big problem was that there are other factors that can influence whether land is rising and falling, such as changing groundwater levels. Some parts of California are sinking as groundwater is pumped out for irrigation.
The breakthrough accomplished by Howell and his team involved writing a computer code that filtered out how the land was rising or falling from non-seismic factors. 
“We wrote a computer code that could try and find the broad, large-scale signal,” Howell said. “It’s trying to find the smooth trend.”
Besides Howell, the other coauthors of the study were Bridget Smith-Konter and Neil Frazer, also at the University of Hawaii; Xiaopeng Tong of the University of Washington; and David Sandwell, of the Scripps Institute of Oceanography at UC San Diego.
The study received funding from the National Science Foundation.

Simple question...!?

WHAT IS WRONG with Tommy Monk, that he is clearly :

1.  Deliberately trying to derail a thread that he apparently has no other genuine interest in;

2. Attempting to link this report with totally unconnected situations in the South Pacific -- and where on that previous thread, he had been equally guilty of derailing and his usual obfuscations;

3.  Keeps on proving more and more just how stupid, dense and uncomprehending a grub he is..

NOW I shall await the usual suspects (a.k.a. 'The Newsfix Twittering Hens' Knitting Circle and InAFlop Fan Club..') to attack me and tell us how and why Tommy is so much smarter than any of his detractors on here, and then claim that Tommy's (well hidden) IQ is actually greater than that of veya, Quill and Victor combined..

Annnnnd how exactly did you tie/connect your crib notes {since you've now proven you LIED} and your lame attempt to skim the article and link it to "SEA LEVELS" ...  

SWEET JESUS ...you do enjoy   trenches DEEP.

Land height is measured by the vertical distance it is above sea level....
Your article is saying seismic activity is causing rise and falls in land height in California... I said the same was happening in the solomon islands area...
Do you agree with the claim in article you posted...!?
Or not...?

Sea level
Sea level is generally used to refer to mean sea level (MSL), an average level for the surface of one or more of Earth's oceans from which heights such as elevations may be measured.

Sometimes he reads the words in his colouring book. Which has no blacks or browns.

Seems, Tommykins has spent a goodly amount of time trolling my every topics; so either he's craving the attention or he's just doing so to goad me with his asinine/redundant/petulant little boy demanding answers that have already been provided but he's proven unable to grasp!   

Yet, his flock of admirers parachute in to attack me for losing patience with him ...and they've not participated {due to their inability to think} but will criticize my frustration with the Village Idiot!

And I have shown others 'evidence' to be inaccurate at best, and at worst to be outright lies!!!



If you think you are so well informed... answer these 3 simple questions... (I have posted the answers on one of the threads already)...


1. What is the estimated global temp rise in Celsius over the last 100 years?

2. What is the temp rise over last 20 years?

3. How does this correlate with solar activity over the last 100 years and last 20 years respectively?
