LOS ANGELES (KABC) – Even amid warnings from health experts of a COVID-19 outbreak, airports across the country were busy this holiday: around 1 million passengers traveled by air on Saturday alone, federal officials estimate . The numbers could be similar if not higher on Sunday. This makes it the busiest travel week since the start of the pandemic. Los Angeles International Airport was less busy than it was last year around this time – but still much busier than this year. throughout the pandemic. nervous about traveling – but decided to see family members for Thanksgiving anyway. Stephanie Ruiz and her sister Tangie wanted to see their 93-year-old grandmother because they didn’t know when they would have another chance to see her. “A little worried,” said Stephanie. “A little regret. But I was happy to see some of my family. “Those who got on the plane said they tried to follow protocols to protect themselves.” It was very scary, “said Shelby Riss, traveler “Everyone is at risk and it’s a very uncertain time. It was difficult but in the end I think we took precautions.” The State of California has asked out-of-state travelers to self-quarantine for two weeks after arrival. Passengers arriving at LAX are required to sign a form acknowledging that they are aware of the recommendation. Copyright © 2020 KABC-TV. All rights reserved.
An earthquake that occurs slowly and quietly deep beneath the North Island can be the key to predicting future earthquakes and tsunamis generated by our biggest fault.
A million dollar, three-year project will increase scientists’ understanding of
Earthquakes “slow” along the Hikurangi Subduction Zone.
Scientists believe the subduction zone, which runs along the east coast of the North Island, could produce “megathrust” earthquakes larger than the scale of 8, such as the one that created the tsunamis that devastated Indonesia in 2004 and Japan in 2011.
The worst case scenario of a major Hikurangi event could include thousands of deaths and injuries, and billions of dollars worth of property losses.
But slow-slip earthquakes – where plate boundary faults release slowly buried tension over days to months instead of seconds in a typical earthquake – can help us better gauge threats.
Their discovery 20 years ago has revolutionized seismology and our understanding of fault mechanics.
Even though it happens off the east coast every few years, no one feels it when it happens – and the driving force remains unclear.
The new project, led by GNS Science, is designed to detect subtle physical changes in a fault before a slow-slip earthquake occurs, to uncover the mechanisms that regulate its timing.
“It will clarify if there is an observable physical change in the fault that could allow the development of a more accurate estimate of when the fault might fail, either in a slow earthquake or, possibly, a fast earthquake,” said project leader Dr Laura Wallace.
Tantalizing evidence has emerged in recent years that increased water pressure near the fault exerts great control over New Zealand’s slow-slip earthquakes.
GNS seismologist Dr Emily Warren-Smith said if this build-up affects slip times, then monitoring water accumulation in the fault could allow better forecasts for slow and possibly fast earthquakes in the future.
But it is possible that the change in fluid pressure within the fault may be a symptom of a slow earthquake rather than a direct cause, said Wallace.
Alternatively, there may be other processes such as a steady increase in stress from tectonic plate motion that controls the tempo of a slow slip earthquake.
The project aims to resolve this dichotomy by installing large-scale submarine and land monitoring instruments in the southern Hawke’s Bay and Wairarapa.
It will monitor changes before, during and after the regularly expected recurring slow slip events offshore in this region in the next two years.
Wallace said the project would establish new ground in seabed geodesy and help put New Zealand at the forefront of global efforts to monitor offshore faults that can produce large earthquakes and tsunamis.
The team departed this weekend aboard the Niwa research vessel Tangaroa to carry out the first set of seabed sensor deployments.
“This project will generate new evidence-based information that will aid significantly in planning and preparedness and make New Zealand safer and more capable of recovering from a major earthquake.”
A separate voyage to the Hikurangi subduction zone – where the Pacific Plate is plunging downward, or “plunging” below the North Island’s east coast – has just finished.
US scientists recently dropped their own specialized equipment onto the ocean floor to visualize subsurface structures, and investigated how fluid is distributed within the sediments.
Program leader Dr Jess Hillman, from GNS Science, said this will allow scientists to better understand how fluid movement is related to activity in our largest offshore faults and the generation of gases beneath the ocean floor.
Shipping specialist Dr Peter Kannberg, from the Scripps Institution of Oceanography in the US, said earthquakes, the stability of the seabed slopes and the release of seabed gases were all regulated in part by the presence of fluids.
“Our instrumentation can detect where this fluid is on Earth, enabling us to better understand the role of fluids in regulating these natural hazards.”
The new three-year project is supported by a $ 960,000 grant from the Marsden Fund.

PM Imran himself created a constitutional crisis in the country, said Mustafa Kamal.
KARACHI (Berita Dunya) – Pak Sarzameen (PSP) Party chairman Syed Mustafa Kamal Tuesday said Prime Minister Imran Khan announced a Rs11 billion package for Karachi but the metropolitan city did not even receive Rs11.
The PSP head said Imran Khan was still not convinced he was the country’s prime minister. Pakistani Tehreek-e-Isaf (PTI) leaders behaved as if they were handling an election campaign, said Mustafa Kamal.
“PM Imran himself created a constitutional crisis in the country because he said he would not have a dialogue with the opposition.
“Dogs bite people from Karachi to Kashmore but there is no vaccine. Karachi has become the dirtiest city in the world with unemployment and the worst transportation system.
“People have lost their trust in all other parties. People from all over the country were brought in for the October 18 rallies but no public interest agenda was discussed at the meeting convened by eleven parties.
“The Karachi people are being treated not seriously and the drama cannot happen anywhere other than Pakistan.”
KARACHI: The Anti-Terrorism Court on Thursday acquitted a hit man who allegedly killed journalist Wali Babar, of a case related to the possession of illegal weapons and explosives. Kamran alias Zeeshan Shani was arrested in June by police from hiding in the Gulshan-e-Maymar area, nine years after he was sentenced to death in absentia by ATC in Kandhkot for murdering a Geo News reporter. Following his arrest, police have charged him in another case of possession of weapons and explosives without a permit, which were allegedly found from him during the raids. The prosecution, however, could not prove this claim in court therefore the ATC-XV judge acquitted the defendant of the indictment, observing that he was given the advantage of the doubt. Geo News reporter Wali Babar was shot dead in the Liaquatabad area of Karachi on January 13, 2011, when he was returning from office.
