Earthquake rattles Alaska
Aftershocks are expected after this morning’s Alaska quake, according to Dr. Lucy Jones, a seismologist with the California Institute of Technology.
She says the average sequence of aftershocks for a quake this size is a 5.8, but that it could be larger than that average figure. She advises to expect many more aftershocks from today’s event.
”We think the number dies off with time, but the relative distribution from large to small is constant,” and weeks to months later, aftershocks will follow, she explains.
For example, the last 5-magnitude aftershock that followed the 1994 Northridge, California, quake was three years after the original event.
There have been at least 30 aftershocks so far for this quake.
Dr. Elizabeth Cochran of the United States Geological Survey says the Anchorage quake was a “normal faulting event” among plates under Alaska.
CNN meteorologist Allison Chinchar just walked viewers through a map that shows where Alaskans felt the shaking — yellow in the video below represents "strong" and orange "very strong" or "severe."
A big concern for the area near the epicenter is what's called liquefaction, a process where the soil becomes saturated with water, which can cause it to erupt into torrents and topple buildings and destroy roads.
Even in downtown Anchorage, a lot of the coastal regions are at significant risk for the potential for that liquefaction to take place, according to Chinchar.

Eric Nelius's home camera caught the earthquake on film as it hit his home in Fairbanks, Alaska — almost 350 miles from the earthquake's epicenter in Anchorage.
In the video, Nelius' wife rushes to grab her children and dogs as the walls begin shaking and a loud rumbling fills the air.
The family is now safe, though their possessions sustained some damage.
Watch it here:
President Trump has been briefed on the Alaska earthquake and is monitoring damage reports, White House press secretary Sarah Sanders said on Twitter Friday afternoon.
"We are praying for the safety of all Alaskans!" she added.
Alaska Gov. Bill Walker has issued a declaration of disaster after Friday morning’s earthquake, according to a post on his Facebook page.
Gov. Walker also said he is in "direct contact" with the White House, and is coordinating with emergency responders.
"From the incident command center established at Joint Base Elmendorf and Richardson we are closely monitoring reports of aftershocks and assessing damage to roads, bridges and buildings," he wrote.
"My family is praying for yours. God bless Alaska."
Two of Anchorage's main hospitals sustained damage following the 7.0 earthquake near the city.
Kjerstin Lastufka, a spokeswoman at Alaska Regional hospital, says the hospital is assessing the main building and offices on campus. “We’re seeing some cracks in the walls and some cracks in the floors, and a little bit of water leaks.”
The hospital emergency room is open, but all elective surgeries and appointments have been canceled. They're not seeing an influx of patients yet, but they are prepared to handle additional patients.
She was in her office at the time of the quake; pictures fell off the wall and plants toppled over on window sills. "It went on for quite some time," Lastufka said.
Providence Alaska Medical Center also announced that though there was some building damage, their ER remains open.
Anchorage Assembly Member Pete Peterson tells CNN the 7.0 earthquake hit just after he had gotten his kids onto the bus at 8:29 a.m.
"Everything shook off the walls. The prints fell off the walls. Glass broke," Peterson says.
Peterson says they lost power at his condo, but he has not seen any damage to the building, and has heard from friends in downtown Anchorage who have not lost power.
