Strongest earthquake in 20 years rattles Southern California

Published

8 minute read

LOS ANGELES — The strongest earthquake in 20 years shook a large swath of Southern California and parts of Nevada on the July 4th holiday, rattling nerves and causing injuries and damage in a town near the epicenter, followed by a swarm of ongoing aftershocks.

The 6.4 magnitude quake struck at 10:33 a.m. Thursday in the Mojave Desert, about 150 miles (240 kilometres) northeast of Los Angeles, near the town of Ridgecrest, California.

Multiple injuries and two house fires were reported in the town of 28,000. Emergency crews were also dealing with small vegetation fires, gas leaks and reports of cracked roads, said Kern County Fire Chief David Witt.

He said 15 patients were evacuated from the Ridgecrest Regional Hospital as a precaution and out of concern for aftershocks.

Kern County District Supervisor Mick Gleason told CNN there were some structural issues with the hospital and some patients had to be moved from one ward to another and that others were taken to a neighbouring building.

Gleason did not say what the structural issues were.

Ridgecrest Mayor Peggy Breeden said that utility workers were assessing broken gas lines and turning off gas where necessary.

The local senior centre was holding a July 4th event when the quake hit and everyone made it out shaken up but without injuries, she said.

“Oh, my goodness, there’s another one (quake) right now,” Breeden said on live television as an aftershock struck.

Gov. Gavin Newsom declared a state of emergency for Kern County. The declaration means that the state will help the county and municipalities in it with emergency aid and recovery efforts.

Ridgecrest Mayor Peggy Breeden praised Newsom for declaring the emergency. She also noted at a news conference that other nearby governments have offered to help the recovery effort.

President Donald Trump said he was fully briefed on the earthquake and that it “all seems to be very much under control!”

Police and fire officials said at a news conference Thursday afternoon that they have enough resources so far to meet needs in the wake of the earthquake. Ridgecrest Police Chief Jed McLaughlin said at a news conference that “we have plenty of resources.”

California Highway Patrol Lt. John Williams says officials have found cracks on several roads in the county, but overpasses and underpasses are in good shape.

A series of aftershocks included a 4.5 magnitude temblor, according to the United States Geological Survey.

“It almost gave me a heart attack,” said Cora Burke, a waitress at Midway Cafe in Ridgecrest, of the big jolt. “It’s just a rolling feeling inside the building, inside the cafe and all of a sudden everything started falling off the shelf, glasses, the refrigerator and everything in the small refrigerator fell over.”

Video posted online of a liquor store in Ridgecrest showed the aisles filled with broken wine and liquor bottles, knocked down boxes and other groceries strewn on the floor. Flames were seen shooting out of one home in the community.

Lucy Jones, a seismologist with the California Institute of Technology’s seismology lab, said the earthquake was the strongest since a 7.1 quake struck in the area on October 16, 1999.

“This has been an extremely quiet abnormal time,” Jones said. “This type of earthquake is much more normal … The long term average is probably once every five or 10 years somewhere in Southern California.”

Jones said that the 6.4 quake centred near the town of Ridgecrest was preceded by a magnitude 4.2 temblor about a half hour earlier.

She said vigorous aftershocks were occurring and that she wouldn’t be surprised if a magnitude 5 quake hit but that they were striking in a remote area, sparsely populated area. “This is an isolated enough location that that’s going to greatly reduce the damage,” she said.

People from Las Vegas to the Pacific Coast reported feeling a rolling motion and took to social media to report it.

Local emergency agencies also took to social media to ask people to only call 911 for emergencies.

“We are very much aware of the significant earthquake that just occurred in Southern California. Please DO NOT call 9-1-1 unless there are injuries or other dangerous conditions. Don’t call for questions please,” the LAPD said in a statement published on Twitter.

There were no reports of serious damage or injuries in Los Angeles, the department said.

The quake was detected by California’s new ShakeAlert system and it provided 48 seconds of warning to the seismology lab well before the shaking arrived at Caltech in the Los Angeles suburb of Pasadena but it did not trigger a public warning through an app recently made available in Los Angeles County.

USGS seismologist Robert Graves said the ShakeAlert system worked properly.

Graves said it calculated an intensity level for the Los Angeles area that was below the threshold for a public alert. The limits are intended to avoid false alarms.

Ashleigh Chandler, a helicopter rescue EMT at Fort Irwin, California, said the quake happened as she was getting ready for a July 4th party.

“I was just in the living room getting everything ready, we start to feel the shaking, so then I look up and then the wine bottles start rattling and I thought, ‘They’re going to fall.’

“My stepson was in the house and my dog, so we just got everyone outside and then it ended. It was like 15, 20 seconds, maybe. It was pretty good shaking, so I’m out of breath.”

“Everyone’s OK.”

Glenn Pomeroy, the head of California’s Earthquake Authority, said the earthquake is “an important reminder that all of California is earthquake country.”

Pomeroy urged the estimated 2,000 people in the region hit by the quake who have California Earthquake Authority insurance policies to contact their residential insurance agencies as soon as possible. Information on how to file a policy claim is on the agency’s website: EarthquakeAuthority.com, he said.

On Extreme Weather, the More We Learn, the More We Know How Little We Knew Before (and Still Don’t Know)

Published on

Fr0m Heartland Daily News

No EF5 tornado, “one of the most catastrophic weather events on Earth … [which can] grow to be more than a mile wide and pack winds over 200 mph—stronger than any Category 5 hurricane on record across the Atlantic basin,” has struck the United States in more than 11 years—the longest such EF5 drought since consistent records have been maintained.

In contrast to many climate scientists and writers with the mainstream media covering climate change, who in their hubris claim the science is settled, Albert Einstein expressed modesty with regard to his knowledge, reportedly saying, “The more I learn, the more I realize how much I don’t know.”

Eistein, a genius by any measure, was not the first to express such wisdom. Socrates, nearly 2,400 years ago, reputedly stated, “The only true wisdom is in knowing you know nothing,” and Aristotle expressed a similar sentiment, saying, “The only true wisdom is in knowing you know nothing.” Would that contemporary climate researchers displayed such a cautious, honest assessment of the state of knowledge in their field about the causes and consequences of contemporary climate change—but they rarely do.

Still, research comes out daily suggesting that far more remains unknown about climate change and the extent to which it drives extreme weather than is known by climate scientists and their journalist sycophants, and is assumed, and built into, climate models. Two recent studies provide examples showing this.

One recent study, published in the peer-reviewed journal Geophysical Research Letters, examines the correlations of tropical cyclone (TC) activity in the Atlantic and Pacific hurricane basins  to multi-decadal variations in sea-surface temperatures tied to shifts in Atlantic Multidecadal Variability (AMV). In analyzing two sets of climate model simulations, adding and subtracting AMV anomalies, researchers found the Atlantic and Pacific respond differently to warm AMV phases, which produce warmer temperatures:

Relative to cold or negative AMV anomalies, a warm AMV:

produces much more frequent TCs (including those making landfalls) over the North Atlantic. This is because AMV+ offers favorable conditions for TC development, including warmer SSTs, higher relative humidity, increased relative vorticity, and weaker vertical wind shear. By contrast, AMV+ causes less frequent TCs across the western North Pacific and South Pacific due to unfavorable conditions for TC occurrence (stronger vertical wind shear and less moist air). The contrasts in TC environment are due to increased zonal flow between the Atlantic and Pacific basins with AMV+.

What they didn’t find to be a factor in hurricane strength or formation was long-term global climate change. Rather, climate models suggest shifts in the Atlantic Ocean current oscillations are the forcing factor for tropical cyclones, or their absence. This study lends credence to the Intergovernmental Panel on Climate Change’s (IPCC) most recent AR6 physical science report, which confirms that there is no detection or attribution of any trend for either the number or strength of tropical cyclones tied to climate change. The IPCC’s assessment suggested that even under the most extreme emission scenarios, it could find no evidence climate change had or would affect tropical cyclones through 2100. (See chart below.)

Despite the IPCC’s clear statements and the findings in this new research, I’d bet money that this year when tropical storms and hurricanes form, especially when one or the other makes landfall and causes damage, mainstream media outlets will publish stories claiming climate change is to blame, citing “studies” from bogus climate science outfits like World Weather Attribution as evidence supporting their claim.

And, of course, hurricanes are only one type of extreme weather event we are only beginning to understand, and, as a result, show how little we know about their formation and cause. Tornados are another such type of event.

Every year, some scientists and reporters in the mainstream media try to tie climate change to the frequency or strength of tornados. Climate Realism has debunked such claims on dozens of occasions, citing research demonstrating there is no trend in increasing numbers or strength of hurricanes. Now the UPI is reporting the same fact.

One recent article published by UPI noted that no EF5 tornado, “one of the most catastrophic weather events on Earth … [which can] grow to be more than a mile wide and pack winds over 200 mph—stronger than any Category 5 hurricane on record across the Atlantic basin,” has struck the United States in more than 11 years—the longest such EF5 drought since consistent records have been maintained. And this is despite billions of additional tons of carbon dioxide being emitted into the atmosphere over that 13-year period. Commenting on this blessed severe tornado drought, UPI writes:

On May 20, 2013, an extremely powerful tornado destroyed a huge part of Moore, Okla. Eleven years later, it remains the most recent tornado to be rated EF5, the strongest possible rating on the Enhanced Fujita Scale. The 11-year gap is the longest since official U.S. records began in 1950.

Before the Moore tornado, the blockbuster tornado season in 2011 led to the confirmation of five EF5 twisters, including the Joplin, Missouri, EF5 that killed 161 people. A total of 50 tornadoes have been rated F5/EF5 since records began in the United States in 1950.

Meteorologist Bob Henson said in 2023 that the current EF5 “drought” is hard to explain since damage estimates can be subjective. Damage to a “well-constructed building” is the most common factor that helps the National Weather Service (NWS) confirm an EF5, yet many homes in the U.S. do not meet that criteria.

During this busy tornado season, think back to how many stories you’ve already seen that mentioned climate change as a factor—modifying their timing, number, behavior, and power. Then, remember  mainstream media column inches and broadcast air-time to the contrary, there is no evidence whatsoever that climate change has, will, or can, even in climate models, impact tornados.

Heartland Institute Research Fellow Linnea Lueken answers the question: “Is climate change making tropical cyclones, meaning hurricanes and tropical storms, worse around the world?” The answer is, “No.”

Moisture situation in Alberta following warm and dry first half of winter

Published on

Agricultural Moisture Situation Update – January 3, 2024

Synopsis

This year’s El Niño has developed into a strong El Niño and currently has a 54% chance of developing into a “historically strong” event, according to NOAA. Current forecasts are projecting El Niño to diminish in April 2024. In the past for Alberta, not all El Niño’s have resulted in warmer and drier weather; however, this unusually warm and dry winter will forever be tied to the 2023-2024 El Niño and will serve as an important data point in the future.

In the 90-days since October 6, 2023, temperatures have remained well above average, with many parts of the northern-half of the province seeing temperatures this warm less than once in 50 years (Map 1). This coupled with low precipitation accumulations has resulted in virtually snow free
conditions across parts of all four of our agricultural regions
(Map 2).

Winter Precipitation Accumulations

November 1, 2023 to January 3, 2024

Since November 1st, the unofficial start to winter in Alberta, precipitation has been well below average across much of Alberta’s agricultural areas (Map 3).

Most of the lands south of Grande Prairie and north of Ponoka are estimated to have a winter thus far, this dry on average, less than once in 50-years. Dry conditions have also persisted across the Central and Southern Regions, ranging from a few widely scattered pockets of near normal to at least once in 25 year lows, centered around the Jenner area (approx. 200 km east of Calgary). Total accumulations currently range from less than 3 mm through parts of the North West and North East Regions up to only 20-30 mm along the foothills and through the western and northern portions of the Peace Region (Map 4).

For the dryer parts of the North West and North East Regions this translates to less than 10% of the 1991-2020 average (Map 5).

Elsewhere, most other lands have received precipitation accumulations that have generally been less
than 50% of the 1991-2020 average.

Perspective

From an annual moisture budget perspective, October through to March generally mark the dry season across the agricultural areas (Map 6), accounting for only about 20% of average annual accumulations across most of the Southern Region, to upwards of 30-35% across the Peace Region.

These significant moisture deficits thus far (50% of the way through the dry season), while discouraging to many, make up only a small portion of the annual moisture budget for an area. Winter is not over yet and if the current forecast is correct, a significant cold snap is on its way over the next few days and it is expected to persist well into next week, perhaps even longer. Along with the cold snap, there is also a forecast for moisture and the promise of at least some snow cover across many areas.

Spring is yet many weeks away and anything can happen between now and then. Furthermore, February on average, is the driest month of the year with most agricultural lands normally receiving less than 15 mm of moisture during this month (Map 6). Let’s hope, for the sake of our producers,
that we descend into at least near “normal” winter conditions and that we see one of Alberta’s famous weather reversals, with respect to moisture. Above average snow fall is very much needed now. Much of the land is extremely dry and has been held tenaciously in the grip of a long-lasting dry
cycle that needs to end soon!
