Why Mount Rainier Is The US Volcano Keeping Scientists Up At Night
Mount Rainier, Washington’s snowcapped peak that stands 4.3 kilometers (2.7 miles) above sea level, has not had a significant volcanic eruption in the last 1,000 years. More than Hawaii’s exploding lava fields or Yellowstone’s vast supervolcano, Mount Rainier has many US volcanologists concerned.
“Mount Rainier keeps me awake at night because it poses a significant threat to the nearby villages. “Tacoma and South Seattle are built on 100-foot-thick (30.5-meter) ancient mudflows from Mount Rainier eruptions,” said Jess Phoenix, a volcanologist and ambassador for the Union of Concerned Scientists, on an episode of CNN’s “Violent Earth With Liv Schreiber.”

The sleeping giant’s deadly potential does not stem from flaming lava flows, which, in the case of an eruption, are unlikely to spread more than a few miles beyond the boundary of Mount Rainier National Park in the Pacific Northwest. According to the US Geological Survey, most volcanic ash will likely drift downwind to the east, away from populated centers.
Instead, many scientists are concerned about a lahar, a fast-moving slurry of water and volcanic rock formed when ice or snow is rapidly melted by an eruption. Lahars gather debris as they run down valleys and drainage channels.
According to Seth Moran, a research seismologist at USGS Cascades Volcano Observatory in Vancouver, Washington, Mount Rainier’s tall height and ice and snow cover make it resilient to eruptive activity. “Hot stuff … will melt the cold stuff and a lot of water will start coming down,” he explained.
“And there are tens, if not hundreds of thousands of people who live in areas that potentially could be impacted by a large lahar, and it could happen quite quickly.”
A lahar is a rapidly flowing debris flow.
The deadliest lahar in recent memory occurred in November 1985, when Colombia’s Nevado del Ruiz volcano erupted. Just a few hours after the eruption began, a flow of mud, rocks, lava, and freezing water surged over the village of Armero, killing over 23,000 people in minutes.
In an episode of CNN’s “Violent Earth,” Bradley Pitcher, a volcanologist and Columbia University lecturer in Earth and environmental sciences, described a hardened, concrete substance that can be difficult to escape.
Pitcher stated that Mount Rainier had approximately eight times the amount of glaciers and snow Nevado del Ruiz had when it erupted. “There’s the potential to have a much more catastrophic mudflow.”
According to the US Geological Survey’s 2018 threat assessment, Hawaii’s Kīlauea volcano is the most dangerous in the US, which is unsurprising given its proximity to the population and periodic eruptions. Mount St. Helens exploded violently in May 1980 and was voted second most dangerous, followed by Mount Rainier in third.
Lahars are most commonly associated with volcanic eruptions, but landslides and earthquakes can also create them. Moran said geologists have discovered evidence that at least 11 massive lahars from Mount Rainier have reached the surrounding area, known as the Puget Lowlands, over the last 6,000 years.
Scientists have not linked the most recent of these lahars, which occurred approximately 500 years ago, to any volcanic activity. According to analysts, the flow event could have been the result of a huge landslide on the mountain’s west face.
The loose, weak rock remains in that location, and Moran and other volcanologists are particularly concerned about the possibility of a similar, spontaneous landslide-induced lahar.

“We now know that the volcano can do it again. “And then we’re in this world where anything can happen at any time,” Moran explained.
“If it were the same size, it would be 10 minutes to the nearest places where people live and 60 minutes to the nearest significant settlements. “And those are very short time frames,” he added.
A 2022 study considered two worst-case scenarios. In the first scenario, a 260 million cubic meter, 4 meter deep (9.2 billion cubic feet, 13-foot deep) lahar would form on Mount Rainier’s west slope. According to Moran, the debris flow would be equivalent to 104,000 Olympic-size pools and could reach the heavily populated lowlands of Orting, Washington, roughly an hour after an eruption, moving at a rate of 13 feet (4 meters) per second.
According to the simulation, a second “pronounced hazard” area is the Nisqually River Valley, where a major lahar may displace enough water from Alder Lake to allow the 100-meter-tall (330-foot-tall) Alder Dam to spill over.
Mount Rainier’s neighbor, Mount St. Helens, farther south in the Cascade Range, erupted four decades ago, causing a disastrous lahar that did not reach any highly populated regions.
Venus Dergan and her then-boyfriend, Roald Reitan, were trapped in the Mount St. Helens lahar while on a camping vacation and are among the few persons known to have survived being swept up in a debris flow.
“I tried to cling on as we were swept downstream, but the tree bark was scraping. … During an interview for CNN’s “Violent Earth,” she recounted feeling it on her legs and arms.
“At one point, I went under the logs and dirt and accepted that this was the end. I was not going to get out of this, and I was going to die.

Following the explosion of Mount St. Helens, the US Geological Survey established a lahar detection system on Mount Rainier in 1998, which has been modified and expanded since 2017.
About 20 places on the volcano’s slopes and the two paths identified as most at risk of a lahar now have broadband seismometers that send real-time data and additional sensors such as trip wires, infrasound sensors, web cameras, and GPS receivers.
Moran explained that the device is designed to identify both a lahar if the volcano erupts in the future and a lahar caused by a landslide.
Because of the constraints of 1990s technology, the original system had limited bandwidth and power requirements, resulting in data transmission every two minutes.
In March, 45,000 kids from Puyallup, Sumner-Bonney Lake, Orting, White River, and Carbonado, Washington, took part in a lahar evacuation simulation. According to the USGS, this was the first time numerous school districts exercised on the same day, making it the world’s largest lahar drill.
Approximately 13,000 pupils walked up to 3.2 kilometers (2 miles) to specified areas outside of the defined lahar zone, while the remaining schools outside the lahar zone practiced sheltering in place.
Moran stated that the fail-safe components of the Lahar detection system are roughly 45 minutes away from the next significant community; thus, that was the time window within which communities had to work.
“Most of what happens at volcanoes is close by, and that’s why you try to keep people away because things happen fast, but lahars can travel a long way from the volcano and have a big impact.”

Hurricane Beryl Roars Toward Jamaica After Killing At Least 6 People In The Southeast Caribbean
KINGSTON, Jamaica — Hurricane Beryl roared toward Jamaica on Wednesday, leaving islanders rushing to prepare after the devastating Category 4 storm killed at least six people and inflicted substantial damage in the southeast Caribbean.
People in Kingston boarded up their windows, fishermen withdrew their boats from the sea, and workers demolished roadside advertising boards to safeguard them from the fierce winds.
Pauline Lynch, a Kingston resident, said she had prepared for the storm by stockpiling food and water. With the wind already whipping up a light rain, Lynch stated, “I have no control over what is coming, so all I can do is pray that all Jamaicans are safe and that there are no deaths or losses.”

Hurricane Beryl Roars Toward Jamaica After Killing At Least 6 People In The Southeast Caribbean
A hurricane warning was issued for Jamaica, Grand Cayman, Little Cayman, and Cayman Brac. Beryl was expected to decrease slightly over the next day or two but remain at or near major hurricane strength when it passes near or over Jamaica on Wednesday, near the Cayman Islands on Thursday, and into Mexico’s Yucatan Peninsula on Friday, according to the National Hurricane Center.
Jamaican Prime Minister Andrew Holness announced that the disaster zone declaration will stay in effect for seven days. He also declared an island-wide curfew from 6 a.m. to 6 p.m. on Wednesday.
Security personnel “will be fully mobilized to maintain public order and aid in disaster relief.” As soon as the cyclone passed, the security forces devised strategic preparations to prevent any potential threat of looting or other opportunistic crimes,” Holness stated.
An evacuation order was also issued for Jamaica villages vulnerable to flooding and landslides. Holness warned Jamaicans to avoid low-lying regions.
A hurricane watch was issued for Haiti’s southern and Yucatan east coast. Belize issued a tropical storm watch extending south from its Mexico border to Belize City.
Late Monday, Beryl became the Atlantic’s first Category 5 hurricane, reaching 165 mph (270 kph) on Tuesday before falling to a still-destructive Category 4. On Wednesday, the storm was approximately 75 miles (125 kilometers) southeast of Kingston. It had maximum sustained winds of 145 mph (230 kph) and was traveling west-northwest at 18 mph (30 kph).
Michael Brennan, Director of the National Hurricane Center in Miami, stated that Jamaica appears in Beryl’s direct path. He asked citizens to locate a secure shelter and stay there until Wednesday.
“We are most concerned about Jamaica, where we are expecting the core of a major hurricane to pass near or over the island,” according to a briefing he gave online.
Jamaica is expected to see a storm surge of 6-9 feet (1.8 to 2.7 meters) over normal tidal levels and severe rains.
On Wednesday, Mexico’s Caribbean coast prepared for Beryl. The government has issued a hurricane warning for the coast of the Yucatan Peninsula, from Puerto Costa Maya to Cancun.
The head of Mexico’s civil defense agency stated that Beryl is expected to launch a rare twin blow on the country. According to Laura Velázquez, the hurricane is forecast to land between late Thursday and early Friday on a rather unpopulated stretch of the Caribbean coast between Tulum and the inland town of Felipe Carrillo Puerto. Because the coast is primarily made up of lagoons and mangroves, there are few resorts or hotels south of Tulum.
As it traverses the Yucatan peninsula, the hurricane is anticipated to diminish to a tropical storm before reemerging as a storm in the Gulf of Mexico over the weekend. According to Velázquez, Beryl is likely to impact Mexican territory again, this time on the Gulf Coast states of Veracruz or Tamaulipas, close to the Texas border.
As Beryl plowed into the Caribbean Sea, rescue personnel in the southeastern islands spread out to assess the extent of the hurricane’s destruction to Carriacou, Grenada.
Officials confirmed three deaths in Grenada and Carriacou, as well as one in Saint Vincent and the Grenadines. Two further deaths were confirmed in northern Venezuela, while five people are missing, officials said. Beryl’s torrential downpour also affected approximately 25,000 people in the area.

The environment minister, Kerryne James, told The Associated Press that a tree fell on a house in Grenada, killing one. She claimed that Carriacou and Petit Martinique suffered the worst damage, with Carriacou losing hundreds of homes and businesses.
Grenada’s Prime Minister Dickon Mitchell stated on Tuesday that there is no power, roads are impassable, and the possibility of an increase in the death toll “remains a grim reality.”
Saint Vincent and the Grenadines Prime Minister Ralph Gonsalves has pledged to reconstruct the archipelago. He stated that 90% of homes on Union Island had been demolished and that “similar levels of devastation” were expected on the islands of Myreau and Canouan.
The most recent powerful hurricane to reach the southeast Caribbean was Hurricane Ivan, which killed scores of people in Grenada 20 years ago.
Grenada nicknamed the “spice isle,” is a major supplier of nutmeg. Mitchell stated that most of the spices are planted in the northern portion of the island, which Beryl most damaged.

NBC is bringing a version of legendary sportscaster Al Michaels back to the Olympics this summer, but with an unexpected twist: his voice will be powered by artificial intelligence.
On Wednesday, NBC said that it will utilize AI software to reproduce Michaels’ voice to offer daily Summer Games summaries to users of its Peacock streaming platform. This marks a significant milestone in the application of AI by a major media firm.

NBC To Use AI Version Of Announcer Al Michaels’ Voice For Olympics Recaps
The employment of an artificial intelligence voice for the Olympics comes at a time when technology has advanced dramatically, particularly in its ability to generate images, sounds, and text. This has sparked concerns in creative industries, such as journalism, regarding how artificial intelligence may—or should—be utilized.
A new tool, “Your Daily Olympic Recap on Peacock,” will allow subscribers to create 10-minute highlights packages incorporating event updates, athlete back stories, and other related content based on their preferences.
The company stated that the highlights could be packaged in approximately 7 million distinct ways, based on 5,000 hours of live coverage in Paris, thereby making AI (artificial intelligence, not the guy) a far more efficient way to give individualized summaries.
“When I was approached about this, I was skeptical but obviously curious,” Michaels stated in a press statement. “Then I saw a demonstration of what they had in mind. I replied, ‘I’m in.'”
An NBC representative told CNN that Michaels is being rewarded for his participation.
A veteran broadcaster, Michaels is now the play-by-play sportscaster for Thursday Night Football on Amazon Prime. He is well noted for his work on earlier Olympic Games broadcasts for NBC and ABC and for announcing the Miracle on Ice Game at the 1980 Winter Olympics in Lake Placid, New York.

Mount Fuji, a UNESCO World Heritage site and Japanese icon, has implemented new climbing limits in response to concerns about overpopulation.
Beginning July 1, climbers must pay 2,000 yen ($12.40) per person, and there is a daily limit of 4,000 climbers.

Japan’s Mount Fuji Implements Tourist Tax In Response To Overcrowding Concerns
“By strongly promoting comprehensive safety measures for climbing Mount Fuji, we will ensure that Mount Fuji, a world treasure, is passed down to future generations,” stated Koutaro Nagasaki, governor of Yamanashi Prefecture, when he announced the new laws earlier this year.
“To revitalize traditional mountain climbing from the foot of Mount Fuji, we shall get a thorough grasp of the Fuji-ko and Oshi cultures that fostered Mount Fuji worship. We hope to connect different civilizations through mountain climbing, which is steeped in religious cultural values.”
Fuji-ko is a religion unique to the mountains.
Human traffic bottlenecks, garbage-strewn hillsides, and poorly dressed hikers – some attempting the trip in sandals – are among the challenges afflicting the renowned Japanese destination.
In addition, new guides will oversee trail safety and notify climbers if they violate mountain etiquette, such as sleeping along the trail, making a fire, or wearing inappropriate attire.
According to prefectural data, five million people hiked Mount Fuji in 2019, up three million from 2012.
“Overtourism – and all the subsequent consequences like rubbish, rising CO2 emissions, and reckless hikers – is the biggest problem facing Mount Fuji,” Masatake Izumi, a Yamanashi prefectural government official, told CNN Travel last year.
In 2023, a volunteer named Tomoyo Takahashi told CNN that she planned to ask tourists to donate 1,000 yen ($6.20) to help maintain the mountain.
“Not everyone pays the 1,000 yen, which makes me sad. “There should be a much higher mandatory entrance fee so that only visitors who truly value Mount Fuji’s heritage come,” she stated.
Takahashi will finally achieve her wish.

The new limitations, however, only apply to Yamanashi prefecture, which has the most popular hiking trails. Fuji is also located in Shizuoka prefecture, which has yet to have any tariffs or visiting restrictions. Governor Nagasaki told reporters that he and Shizuoka’s governor will meet at the end of the climbing season to swap notes.
Overtourism has become a major issue in Japan since the country reopened during the pandemic.
Locals in Kyoto’s historic Gion area have expressed concern over tourists flocking to photograph and sometimes harass the geisha who live and work there, giving them the term “geisha paparazzi.”
While the city has posted signs and boards urging visitors not to photograph geisha, several locals told CNN Travel that more is needed. The neighborhood council proposed issuing fines or penalties.
Hatsukaichi, in Hiroshima Prefecture, southwestern Japan, has also been hit. The little hamlet is notable for its orange “floating shrine” torii gate, part of a 1,400-year-old Shinto complex.
In October 2023, the town started charging 100 yen (62 cents) for visitors to the temple. The “tourist tax” funds the site’s maintenance and infrastructure.
