Earthquake

The coronavirus pandemic has forced challenges and changes to almost every public-facing entity, including national parks. At Craters of the Moon National Park, tours of the lava caves were stopped in March. But another natural disaster may keep the caves closed even longer.

It’s been three months since a 6.5 magnitude earthquake struck northwest of Stanley on March 31. Since then, Stanley residents have felt many more rumbles and geologists have deployed to central Idaho, investigating what happened and what it can tell us about Idaho’s seismic nature.

Idaho experienced a 6.5 earthquake on March 31. That was pretty scary and unusual for Idaho. But, it was also really exciting for geologists in the state, country and world. In fact, this earthquake, and the subsequent aftershocks, were so unusual that they’re telling scientists quite a bit about the earth’s crust in Idaho and the Mountain West.

This week was packed (there was that earthquake, changes to how the May 19 primary will be run, and getting homeless Idahoans tested for COVID-19). 

Dozens of aftershocks have continued to rattle central Idaho after a six-point-five magnitude earthquake hit the region Tuesday night. There are still no reports of major damage or injuries.

The 6.5 magnitude quake was recorded about 6 p.m. Mountain Time Tuesday evening, shaking homes from Boise to as far north as the Canadian border.

The recent outbreak of earthquakes in eastern Idaho seems to be diminishing. Since a 5.3 quake jolted the region around Soda Springs at the beginning of the month, close to 2,000 aftershocks have been measured.

Eastern Idaho continues to be rattled by earthquakes. Since a magnitude 5.3 quake hit near Soda Springs on September 2, the ground has frequently been in flux.


Montana Hit With 5.8 Magnitude Earthquake

A 5.8 magnitude earthquake struck western Montana a little after midnight Thursday.

 

The early morning quake was felt across hundreds of miles from eastern Washington to western Montana to Idaho. According to the U. S. Geological Survey (USGS), the earthquake’s epicenter was around six miles southeast of Lincoln, Montana and about eight miles underground.

A new report from the U.S. Geological Survey says southeast Idaho is overdue for an earthquake. Sometime within the next 50 years, USGS says the so-called “big one” will start rattling southeast Idaho along the Bear Lake Fault.

They estimate the likelihood of a magnitude 6.0 quake coming in the next half-century at 63 percent.

Jonathan Katz talks more about his award-winning book, The Big Truck That Went By: How the World Came to Save Haiti and Left Behind a Disaster.  Mr Katz was the only full time U.S. news reporter in Haiti when the quake struck.  His on-the-ground reporting for the Associated Press helped inform the world about the scope of the disaster, and he stayed in Haiti in the months that followed to document how and why well-meaning world relief efforts fell short.

On a hot January afternoon in 2010, reporter Jonathan M. Katz heard a loud rumbling outside his home in the hills above Port-au-Prince, Haiti.  At first, he thought it was a water truck. Then the bed began to vibrate, bottles shimmied on a nearby table, and the floor started to move. The roar increased as the deadliest earthquake in the history of the Western Hemisphere unleashed its full force. Mr. Katz survived. Thousands upon thousands of others were not so lucky.

State emergency management agencies in Idaho, Oregon and Washington along with their federal counterparts at FEMA, are conducting a drill through the end of the week to prepare for a catastrophic disaster. The potential disaster the three states are role playing is a 9.0 earthquake on what’s called the Cascadia Subduction Zone. That would create huge tsunamis that would devastate the coasts of Oregon and Washington.

The Washington National Guard -- joined by officers from Oregon and Idaho -- are preparing for a massive military relief effort.

People standing above the epicenter of a large earthquake will feel the ground shaking before people on the periphery of the quake. The same can be said of their smartphones.

Researchers at the U.S. Geological Survey are trying to figure out whether smartphones might be used to give earthquake warnings.

Ben Brooks, with the USGS, says if a computer was checking for simultaneous movement of a large number of smartphones, it could give people on the periphery of a quake a 10-or-20-second warning.
He says that's enough time to stop a surgeon from starting an operation.

Shital Dhakal is a grad student at Boise State, and he's lived in Idaho for the last year-and-a-half. When he heard news of the earthquake in Nepal that has killed more than 4,000 people, he immediately tried to reach out to his family – but their cell service was down.

Three earthquakes up to magnitude-4.2 and nearly a half-dozen aftershocks have jolted northern Idaho, with residents from Washington state to Montana saying they felt the tremors.

A Bonner County emergency dispatcher in Sandpoint said Friday morning that no injuries or damage were reported.

The U.S. Geological Survey says a magnitude-4.1 quake hit first, around 7:32 p.m. Thursday. It was centered 30 miles northeast of Hayden.

The latest earthquake swarm in central Idaho could help scientists better understand quake belts extending from Yellowstone National Park.

The most recent swarm in the Challis area started this week and so far 20 quakes have been recorded, the largest a 3.7 magnitude on Monday.

No damage has been reported.

Scientist Mike Stickney of the Montana Bureau of Mines and Geology based in Butte, Montana, says a portable seismograph left in place after a swarm last summer has helped pinpoint the earthquakes.

Custer County officials in central Idaho say there's no damage from an earthquake that shook the area Monday morning.

The U.S. Geological Survey says the 3.7-magnitude temblor occurred about 10:20 a.m. and was located about a mile east of Challis and about a mile deep.

Linda Lumpkin of the Custer County Sheriff's Office says the quake was widely felt among residents in the sparsely populated area.

But she says residents are used to the ground shaking after a swarm of quakes up to 4.9 in magnitude last spring that peaked in mid-April.

Any parent of a rambunctious youngster can tell you trouble might be afoot when things go quiet in the playroom. Two independent research initiatives indicate there is a comparable situation with the Cascadia earthquake fault zone.

A new U.S. Geological Survey report indicates a slightly greater earthquake hazard in the Greater Yellowstone region of Wyoming, Montana and Idaho than previously thought.

And the USGS map of seismic hazards shows that the region is as seismically hazardous as anywhere in the United States. 

University of Utah geophysicist Bob Smith tells the Jackson Hole News & Guide that the nationwide USGS earthquake hazard maps and adjoining documents were last updated in 2006.

Research geologists have just finished a field trial to test a less invasive way to complete seismic hazard surveys.

Seismographs have picked up a swarm of earthquakes in the northwestern corner of Yellowstone National Park, including dozens early Tuesday.

The University of Utah Seismograph Station reported five small earthquakes including those with magnitudes of 3.4, 2.7 and 3.2 in a 20-minute period starting at 3:33 a.m. in an area 16 to 18 miles south of Gardiner.

A swarm of central Idaho earthquakes that rattled Challis residents for more than a month appears to be dying out.

But seismologists say five portable seismographs have provided new information about the area that saw a sequence of quakes up to 4.9 in magnitude, peaking in mid-April.

Mike Stickney with the Montana Bureau of Mines and Geology based in Butte, Montana, says the earthquakes are occurring on a northwest trending zone on the west side of the Salmon River.

Geologists plan to install three portable devices known as seismometers or seismographs in the Challis area in central Idaho to help experts better understand a recent flurry of earthquakes.

The U.S. Geological Survey has recorded a sequence of quakes rumbling the area, the largest of which was a 4.9-magnitude quake on Saturday which shook pictures off walls. Challis residents also felt earthquakes above 4.0-magnitude on Monday and April 10.
