At least 2 dead and 11 injured after earthquake, sheriff’s office says
At least two people are dead after a 6.4-magnitude earthquake struck northern California on Tuesday, according to the Humboldt County Sheriff’s Office.
Officials are expected to make an announcement later Tuesday.
Chances for strong aftershocks in Northern California continue into next week, official says
Scientists are warning people in Northern California to prepare for the possibility of a strong earthquake next week, said Cynthia Pridmore of the California Geological Survey’s Department of Conservation.
It came after state officials said there were about 80 aftershocks already reported after a 6.4-magnitude earthquake struck Northern California early Tuesday.
The U.S. Geological Survey’s latest earthquake forecast adds that in addition to the chance of a magnitude 5 earthquake, “there is a greater than 99% chance of a magnitude 3 and greater earthquake next week, and most likely 5 to 24 of those.” and will happen.”
Aftershocks of magnitude 3 and above are large enough to be felt up close, the USGA said, adding that a magnitude 5 is enough to cause damage.
Pridmore suggested that those living in the area make sure their emergency equipment is ready and a plan is in place in case of another earthquake.
While officials are assessing the damage already done, Pridmore said the California Department of Geological Survey is sending scientists and engineers to document the earthquake and its characteristics.
Up to 80 aftershocks felt in Northern California, including a 4.6 magnitude quake
About 80 aftershocks shook parts of Northern California after a 6.4-magnitude earthquake struck the area early Tuesday, according to California Office of Emergency Services Director Mark Ghilarducci.
The largest earthquake in Rio Dell was 4.6 magnitude, which he described as one of the “most severe areas.”
The director said that the evaluation is still going on. He said that in particular, the dam was broken and other damages were reported in the city of Fortuna.
The state’s operations center will remain open until at least tonight to help people navigate the damage from the earthquake and aftershocks, Ghilarducci said.
No fatalities reported so far following earthquake, authorities say
There were some injuries reported following the 6.4 magnitude earthquake in Humboldt County, California, according to California Office of Emergency Services Commissioner Mark Ghilarducci.
“We have received some injuries related to this particular incident. We are still assessing the total number,” he said, adding that the injuries ranged from light to moderate.
“There is still no confirmed number of deaths,” he noted.
California’s early warning system worked as expected, emergency services director says
California Governor’s Office of Emergency Services (Cal OES) Director Mark Ghilarducci said the state’s new earthquake early warning system worked as expected when a 6.4 magnitude earthquake struck the northern part of the state.
Ghilarducci said the system sent warnings 10 seconds before an earthquake was felt. The warning reached nearly 3 million people in the region, he said in a press conference held on Tuesday.
That 10-second warning gave people a chance to get to a safe place, he said.
“The system worked as we hoped and as we worked to design it,” the director added, saying the earthquake was “greatly felt.”
Some background: The California Earthquake Warning System uses ground motion sensors to detect earthquakes before people feel them, according to its website.
When those sensors receive data, an alert is then pushed to people’s phones via the app, as well as the Government’s Wireless Emergency Alert (WEA).
Today’s earthquake rattled Northern California. Here’s how intense it was.
Take a look at how Tuesday’s 6.4-magnitude earthquake affected different parts of Northern California — and its different levels of intensity.
Smaller quakes are being reported in Northern California. Here’s what to know about aftershocks
More than three dozen small earthquakes were reported around northern California where a magnitude 6.4 earthquake struck early Tuesday, according to the US Geological Survey.
These tiny movements are called tremors. Here’s what to know about them as the area continues to assess the damage.
What is aftershock? An aftershock is a smaller earthquake that occurs in the same general area as the larger movement, according to the US Geological Survey (UGS). These small earthquakes are caused by the faulting of large earthquakes, the USGS said on its website.
UC Berkley’s seismology lab puts it this way:
The USGS says the frequency of aftershocks is decreasing over time.
What is the difference between an aftershock and a “fleet?” What happened in Northern California on Tuesday was described as an earthquake and an aftershock because there was a “mainshock”, or a larger, larger, recognizable earthquake.
“On the other hand, a swarm is a sequence of mostly small earthquakes that cannot be identified as a major shock. A swarm is usually short-lived, but can continue for days, weeks, or sometimes even months. They often recur in the same locations. one. Most of the currents are related to the Earth’s heating activity,” the USGS said.
About 72% of Humboldt County is without power
More than 72% of customers are without power in Humboldt County, California, following a 6.4 magnitude earthquake last Tuesday.
According to poweroutage.us, 71,763 customers were without power as of 8:39 a.m. PT. This is a significant increase from the 55,176 customers who lost power at 3:15 am PT.
More than 3 dozen smaller quakes struck the area after Tuesday’s main temblor, USGS says
From CNN’s Jason Hanna, Carol Alvarado and Stella Chan
After a 6.4-magnitude earthquake struck Northern California’s Eureka region early Tuesday, more than three dozen smaller earthquakes hit the ground afterward, the U.S. Geological Survey reported.
Some were as strong as a 4.6 magnitude earthquake.
The main quake also produced at least some tremors from the Oregon coast to south of San Jose, California, public reports compiled by the survey show. There is no tsunami threat, the National Oceanic and Atmospheric Administration said.
Tuesday’s temblor comes a year after a 6.2-magnitude earthquake struck near Humboldt County in Cape Mendocino on Dec. 20, 2021, and caused minor damage to buildings in the area.
Can there be a 12.0 earthquake?
The size range is open, meaning that scientists do not have a limit on the size of an earthquake, but there is a limit to the size of the earth. A magnitude 12 earthquake requires a fault larger than the Earth itself.
What is the maximum possible earthquake? According to the USGS, earthquakes of magnitude 10 or greater cannot occur. The largest earthquake ever recorded has a magnitude of 9.5. It happened in 1960 near Valdivia, Chile, where the Nazca plate subducts the South American plate.
Is it possible for a 12.0 earthquake?
No, earthquakes of magnitude 10 or greater cannot occur. The magnitude of an earthquake is related to the length of the fault it is on. That is, the longer the fault, the larger the earthquake.
What would happen if an earthquake was 12?
Throw a Cover
- Get down on your hands and knees before the earthquake hits. …
- Cover your head and neck (and your entire body if possible) under a sturdy table or desk. …
- Keep it on your head (or head and neck) until the shaking stops.
What is largest earthquake possible?
Earth Science FAQs – Geology and Tectonics According to the USGS, earthquakes of magnitude 10 or greater cannot occur. The largest earthquake ever recorded has a magnitude of 9.5. It happened in 1960 near Valdivia, Chile, where the Nazca plate subducts the South American plate.
Is a 13.0 earthquake possible?
So, let’s get back to the question: The magnitude of the earthquake is related to the length of the fault. The problem with dimension 13 is, that it is not possible according to this concept because of the physical limitations of the earth.
How long do 7.0 earthquakes last?
Generally, just seconds. A strong tremor during a moderate or large earthquake usually lasts about 10 to 30 seconds. Land reshaping causes multiple earthquakes (aftershocks) that can occur repeatedly for weeks or months.
Why is a 10.0 earthquake impossible?
That is, the longer the fault, the larger the earthquake. A fault is a fracture in the rocks that make up the Earth’s crust, along which the rocks on both sides pass one another. No fault large enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would spread over most of the planet.
What would happen if an earthquake was 12?

How strong is 12 magnitude earthquake?
It caused massive destruction and loss of life, and created a tsunami that reached Japan and the Philippines. A magnitude 12 earthquake would be unimaginable in its magnitude.
Will there ever be a 10.0 earthquake?
Scientists say the magnitude of the event is unlikely because earthquakes are related to the length of faults, or cracks in the ground. The great earthquake in China in 1960 was on a fault 1,000 miles long and there is no known fault large enough to trigger such an event.
Can an earthquake last 1 second?
How long are earthquakes? Generally, just seconds. A strong tremor during a moderate or large earthquake usually lasts about 10 to 30 seconds. Land reshaping causes multiple earthquakes (aftershocks) that can occur repeatedly for weeks or months.
Can an earthquake end in seconds? An earthquake is the shifting of the earth’s plates, which results from a sudden shaking of the ground that can last from a few seconds to a few minutes. Within seconds, the initial mild tremors can intensify and become violent.
Can you feel a 1.0 earthquake?
Intensity 1: Not noticed â Not noticed except in very few cases under certain favorable conditions.
What size earthquake can you feel?
The size, location, and depth of the earthquake, and the extreme soil conditions determine how large and powerful any particular event can be felt. Typically, people report feeling an earthquake greater than about 3.0.

Is a 10 0 earthquake possible?
No, earthquakes of magnitude 10 or greater cannot occur. The magnitude of an earthquake is related to the length of the fault it is on. That is, the longer the fault, the larger the earthquake.
How long does a small earthquake last?
An earthquake can last from seconds to minutes. While tremors from small earthquakes typically last only a few seconds, strong tremors during moderate to large earthquakes, such as the 2004 Sumatra earthquake, can last for several minutes. 4.
What does a 1 earthquake feel like?
A large, distant earthquake will feel like a slow bump that follows for a few seconds after a strong tremor and a sharp tremor may be felt for a short period of time. A nearby earthquake will feel like a small sharp tremor followed by several quick sharp tremors.
Do Little earthquakes mean big one coming?
Clusters of earthquakes before the main event act as earthquake precursors. When a major earthquake is in preparation, the area where the earthquake will occur will experience a sequence of smaller earthquakes before the event.
