The powerful earthquake that struck Baja California and the southwestern United States in April actually moved an entire California border city, NASA radar images show.
A NASA aircraft flying above the fault system responsible for the April 4 earthquake in Baja California recorded how the quake deformed Earth's surface using radar. The resulting map, overlaid atop a Google Earth image of the region shows major fault systems (red lines), while recent aftershocks are denoted by yellow, orange and red dots.
Calexico, Calif., near the U.S.-Mexico border, moved as much as 2 1/2 feet (80 cm) south and down into the ground due to the magnitude-7.2 earthquake on April 4.
Called the El Mayor-Cucapah earthquake, the temblor was centered 32 miles (52 km) south-southeast of Calexico and was the strongest quake to strike the region in nearly 120 years. Two people were killed and hundreds more were injured.
Shaking and moving
It's not the first time a town has moved. The massive 8.8-magnitude earthquake that struck Chile earlier this year moved the city of Concepción at least 10 feet (3 meters) to the west. That quake was the fifth most powerful temblor in recorded history.
Another example of how quakes move as well as shake: In the 6.9-magnitude 1989 Loma Prieta earthquake, which occurred along the San Andreas Fault in southern California, the Pacific plate moved 6.2 feet (about 2 m) to the northwest and 4.3 feet (1.3 m) upward over the North American plate.
Over the long run, earthquakes and shifting fault lines remake the planet. The slip-sliding motion of the San Andreas fault causes San Francisco

Nothing needs to be redefined. The monuments hold in every state.
No crapshoot. Nobody wants to be in southern California, so the definition has always been Ventura county, and all other counties that are north of the Tehachapi are northern California.

Uh, no.
San Andreas runs all the way to the Southern edge of California, and beyond into the Gulf of California. Heading from the southern border, it turns and cuts across much of southern California, before heading along towards the Santa Cruz mountains. It finally heads offshore immediately south of San Francisco, although I admit I didn’t realize it skirts back onshore for brief segments north of San Francisco. Nonetheless, the whopping majority of the onshore portion of San Andreas is in the southern half of California.
Loma Prieta is just under 30 miles from where the San Andreas first heads out so sea, just south of San Francisco. Out of 800+ miles, that’s what I refer to as “near the northern edge.”
The San Andreas heads out to sea at the northern end of Tomales bay.
And I repeat, more of the fault that is in California is in what the state itself defines as northern California.
Not far enough, needs to move California about another 1,000 miles west.

THis is what many in Calif say about the people who live in other states and have weather disasters that the tax payers have to pickup.
What taxpayers in which states? Taxpayers pickup weather disasters? Are you saying taxpayers do cleanup? I don’t understand your sentence structure. Did you go to school in California?
You know exactly what I said.
Repeat it all you want.
Once was enough for everyone but you.
