(WYOMING) — Another hydrothermal explosion has occurred at Yellowstone National Park, highlighting the unstable nature of the reserve’s extensive volcanic network, the U.S. Geological Survey says.

On June 13, a small hydrothermal explosion occurred at Yellowstone’s Biscuit Basin — a popular thermal area located less than 2 miles northwest of Old Faithful, according to the USGS.

The explosion occurred at 5:09 a.m. local time and did not cause any injuries, according to the USGS. A new pool formed as a result of activity.

Monitoring equipment at Biscuit Basin registered anomalous activity, including seismic activity and infrasound — a low-signal acoustic signal — coming from the direction of the Black Diamond Pool, where a hydrothermal explosion occurred on July 23, 2024.

When park rangers went to investigate, they noticed that water in the Firehole River flowing downstream from Biscuit Basin included a light-gray to milky runoff, an “odd” observation, according to the USGS.

A camera installed at the Black Diamond Pool in 2025 recorded a dark-colored stream jetting out of the ground north of the pool. Geologists assessing the activity discovered that large volumes of hydrothermal water had surged into the Firehole River from three sets of newly formed vents in the Black Diamond Pool.

The vents allowed pathways to the surface for water measuring at or slightly above boiling temperatures. As the water converted to steam, it triggered a hydrothermal explosion, the USGS said.

One of the vents was found to be a crack to the north-northwest of the pool measured about 61 feet long and 5 feet wide in some places. The crack was surrounded by several rocks that had been ejected during the explosion. Another linear vent located to the northeast measured about 49 feet long.

The water measured between 185 degrees and 200 degrees Fahrenheit, the USGS said.

Days after, geologists found that a new pool containing “vigorously” boiling water — described as gray in color and full of silt — had formed near the middle of the vent group.

The pool likely formed as a result of collapse of the land beneath it.

Camera observations taken on June 18 showed intermittent episodes of spouting within the pool. Some of the water spouts reached between 20 feet and 30 feet, geologists said. When not displaying geyser-like activity, the pool was actively boiling.

The explosion emphasizes the unstable and hazardous nature of hydrothermal activity in the region, the USGS said.

No one was impacted by the latest incident because Biscuit Basin has been closed since the 2024 explosion.

Temporary seismic monitoring stations have been installed within the basin to record signals related to the evolution of the newly formed vents, the USGS said.

(LOS ANGELES) — Police arrested an 18-year-old suspect in a shooting Monday evening at a Northern California library, which left two dead and one injured, according to the Chico Police Department.

Shots were fired soon after 5 p.m. at the Chico branch of the Butte County Library in Chico, California. Law enforcement took the suspect into custody as he fled the library out the back, Chico Police Chief Billy Aldridge said in a news conference on Monday.

The suspect, identified as Bradley Scott Sayer, was arrested and is currently being held in the Butte County Jail on two counts of murder, according to Chico police.

Officers said the suspect wanted a Columbine massacre-style shooting and did not know the victims.

On April 20, 1999, two students opened fire at Columbine High School in Littleton, Colorado, gunning down 12 of their fellow students and a teacher before killing themselves.

According to law enforcement officials, Sayer was wearing clothing like that of Columbine killer Eric Harris. And Sayer, the officials tentatively believe, is associated with an online fandom group of mass killers that has been linked to previous shootings. The officials believe he acted alone over his Columbine obsession.

“The incident this evening was obviously very sad, traumatic for a lot of people,” Aldridge said in the news conference. “Very traumatic for our community.”

Police are waiting to notify the victims’ families before releasing their names. In addition to the two dead, a child was taken to the hospital with minor injuries, Aldridge said.

All branches of the Butte County Library are closed on Tuesday.

Law enforcement said they are continuing to investigate the shooting, and there is no current danger to the public. They believe the shooter acted alone. The Chico Police Department is collaborating with the Butte County Sheriff’s Office and the FBI in the investigation, which remains ongoing.

(LOS ANGELES) — Firefighters continue to battle a massive blaze at a Los Angeles warehouse that has been burning for nearly a week, which has spread heavy smoke for miles.

As of Tuesday morning, the fire at the Boyle Heights Storage Facility, which stores frozen food, is still ongoing, according to the Los Angeles Fire Department.

Due to the facility’s architecture and cold storage shelving, crews have to battle the blaze from the outside as they cannot ventilate the insulated roof, Los Angeles Fire Department Chief Jaime Moore told reporters Monday.

“The entire roof has been compromised, and it is sitting on top of those 65-foot towers,” he said. “Imagine going to Costco, or any other large convenience store, [like] Home Depot, any of those that have the large racks. Imagine the ceiling sitting down on top of those racks. It’s extremely dangerous, and I don’t foresee ever putting our firefighters in that type of danger.”

The fire at the facility, which Moore said contains about 85 million pounds of frozen food, began June 17, and a shelter-in-place order was temporarily in place.

Lineage Logistics, which operates the warehouse, said in a statement Monday that the fire began “while testing was being conducted by contractors of the third-party owner of the solar array located on the facility’s roof.”

Lineage said that no hazardous materials are stored in the facility and that it pumped out the ammonia inside and transported it.

California Gov. Gavin Newsom declared a state of emergency on Saturday, and additional resources were sent to assist, including specialized aircraft with high-capacity water cannons.

While the fire has not spread to other buildings, residents and businesses near the area have been feeling the effects from miles away.

Heavy smoke from the blaze raised the Air Quality Index to unhealthy levels in East Los Angeles, Boyle Heights, and the San Gabriel Valley since last Wednesday, officials said.

In Boyle Heights, the air quality was at “very unhealthy” levels Sunday evening with an AQI of 298, prompting warnings for people to stay indoors, according to the South Coast Air Quality Management District.

AQI values at or below 100 are generally thought of as satisfactory, according to federal air regulators.

By Monday morning, many of the affected neighborhoods saw lower levels, with Boyle Heights recording an AQI of 79, but they were still high enough to affect some residents with respiratory issues, according to officials.

Although a shelter-in-place order was not issued, LA Mayor Karen Bass and other city officials offered over 1,000 air purifiers and face masks to residents who needed them.

Lines for those purifiers stretched outside locations on Monday.

The South Coast Air Quality Management District’s Particle Pollution Advisory remained until Tuesday afternoon.

(NEW YORK) — A wildfire burning in Utah tripled in size overnight, prompting mandatory evacuations of homes and campgrounds and completely closing a highway in the mountainous area.

Fueled by drought conditions and wind gusts up to 50 mph, the Cottonwood Fire in Beaver County started Monday afternoon and spread rapidly overnight, according to Utah Fire Info.

As of Tuesday morning, the blaze has burned more than 10,000 acres and was 0% contained, officials said.

The Cottonwood Fire ignited around 3:36 p.m. on Monday, threatening populated areas in Beaver County, according to officials.

Just after 9 p.m. local time on Monday, residents in the Eagle Point and Merchant Valley areas of Beaver County were ordered to evacuate immediately as flames bore down on the area, authorities said.

The cause of the blaze is under investigation.

The Cottonwood Fire is one of 342 wildfires currently burning across Utah, consuming more than 64,000 acres combined, according to Utah Fire Info.

The biggest active fire is the Iron Fire burning in Juab County, about 28 miles southwest of Provo. As of Tuesday morning, the Iron Fire had burned 31,304 acres and was 9% contained, said Al Nash, public information officer for the Great Basin Team 3, a federal agency in charge of the incident.

Nash told ABC News that firefighters battling the Iron Fire are bracing for another day of hot, dry and windy conditions.

The fire has prompted numerous evacuations in the area, including the complete evacuation of the town of Eureka, which has a population of just over 600.

“Our firefighters are expecting to have another challenging day,” said Nash, adding that humidity is expected to drop into the single digits.

Kelly Wicken, a spokesperson for the Utah Division of Forestry, said the blaze started on private land and has now spread across Juab and two other counties, crossing onto federal land and shutting down a highway.

Before the fire, the National Weather Service had issued red flag fire danger warnings for a large part of the state.

Red flag warnings for fire weather danger are in place across southern Utah and through much of western and central Colorado. Strong winds and low humidity are expected to fuel the existing fires and enable new fires to spark and spread rapidly.

(RIVERVIEW, Fla.) — A 3-year-old boy died after being left in a hot car in Florida, according to authorities.

Deputies responded to a home in Riverview, just outside of Tampa, at about 10:40 p.m. Saturday after the boy’s father found him unresponsive in a parked car, the Hillsborough County Sheriff’s Office said.

The boy was taken to a hospital where he was pronounced dead, the sheriff’s office said.

The temperature hit a scorching 95 degrees in Riverview on Saturday, and with humidity, it felt hotter than 100 degrees.

It’s not clear how long the boy was in the car.

Hillsborough County Sheriff Chad Chronister called the death a “tragedy” and warned, “A vehicle can reach lethal temperatures within minutes.”

“We urge every parent and caregiver in our community to make hot vehicle safety a priority,” the sheriff said in a statement. “Never leave a child unattended in a vehicle, even for a moment.”

No charges have been filed at this time and the investigation is ongoing, according to the sheriff’s office.

At least eight children have died in hot cars so far this year in the U.S., according to national nonprofit KidsAndCars.org. Last year, at least 37 children died in hot cars across the country, KidsAndCars.org said.

(NEW YORK) — An emotional Savannah Guthrie spoke out on Tuesday following new reports that a ransom note said her mother, Nancy Guthrie, died shortly after she was abducted.

The “Today” show host’s 84-year-old mother was kidnapped from her Tucson, Arizona, home in the early hours of Feb. 1 and remains missing, according to authorities.

Various ransom notes were sent to the media in the days after Nancy Guthrie’s disappearance. The second ransom note received by a Tucson television station, days after Nancy Guthrie’s abduction, said she died shortly after she was taken and was buried in nature, sources familiar with the investigation told ABC News.

Savannah Guthrie wiped away tears as she addressed the news on “Today,” saying, “I’m not involved in our coverage, but I can’t pretend I’m not here.”

“And so, since I am, I wanted to just take the opportunity to ask people — to really, to beg people — to come forward,” she said. “Somebody knows something.”

“This is a news story today that is on your radar, but this is the life that my sister lives, that I live, that my brother lives, that our extended families live, that our children live, every day. And we are in agony,” Savannah Guthrie said through tears.

“Please do the right thing. … We love our mom, and we’ll never stop looking for her, ever,” she said.

Images from Nancy Guthrie’s doorbell camera showing a masked man at her house were released by authorities early on in the investigation, but the 84-year-old’s whereabouts remain unknown, and the suspect remains unidentified.

Anyone with information is urged to call 911, the FBI at 1-800-CALL-FBI, or the Pima County Sheriff’s Department at 520-351-4900.
