Experts say Hawaii's Kilauea isn't done erupting. And it's not the only volcano rumbling.
Since December 2024, Kilauea has erupted about once a week, making it one of the world's most active volcanoes, the U.S. Geological Survey says.
Kilauea isn't the only volcano erupting. More than 50 volcanic eruptions have been reported around the world this year. The eruptions contribute significantly to earthquakes of all sizes, according to the Hawaiian Volcano Observatory.
About the Kilauea eruption in 2025
The Kilauea eruption that produced the 1,000-foot plume occurred in a closed area of Hawaii Volcanoes National Park about 200 miles and several islands southeast of Honolulu. Hawaiian Volcano Observatory status report says the lava poses no immediate threat to people who live in the area.

Other volcano eruptions and the Ring of Fire
The Ring of Fire is a horseshoe-shaped region in the Pacific about 25,000 miles long that contains more than 450 volcanoes, according to the National Oceanic and Atmospheric Administration.
The ring, NOAA says, extends "from the southern tip of South America, along the West Coast of North America, across the Bering Strait, down through Japan and into New Zealand." Its volcanoes extend farther south into Antarctica.
"Three out of every four live volcanoes on Earth are here,' National Geographic says. 'Almost all earthquakes happen here, too."
The Ring of Fire is the result of plate tectonics − moving slabs of rock millions of square miles across. They can collide with or pull away from one another. Heavier plates can slide beneath lighter ones, heating and melting the rock and creating magma. Volcanoes form as the magma rises through the Earth's crust.
How volcanos differ in shape and size
How many volcanic eruptions have occurred in 2025?
Fifty to 70 volcano eruptions are recorded around the world each year. According to the Global Volcanism Program, 54 volcanic eruptions have been confirmed this year as of May 2. A dozen of those eruptions have been in new locations.
Underwater volcano lurks off the Oregon coast
The massive undersea Axial seamount volcano reaches more than 3,600 feet above the seabed about 300 miles off Oregon. It last erupted in 2015.
'A year ago, Axial seemed to be taking a nap, but now it's waking up, and we think it's likely to erupt before the end of 2025,' Bill Chadwick, a volcanologist with Oregon State University and part of a team that's studying the volcano, told USA TODAY at the time.
A series of instruments placed around the volcano indicates a reservoir has been refilling with magma since its last eruption, gradually inflating so that it's bulging upward.
Overall, the undersea volcano continues to grow but it "sure doesn't seem like anything is imminent," he wrote.

New COVID variant 'Stratus' is spreading in the U.S. and worldwide: What are the symptoms?
A new COVID variant is climbing the ranks in the U.S., becoming the third-most common strain of the summer. Variant XFG, colloquially known as "Stratus," was first detected in Southeast Asia in January but accounted for less than about 0% of cases in the United States until May. By late June, it was estimated to account for up to 14%, according to the Centers for Disease Control and Prevention (CDC). The World Health Organization (WHO) added XFG to its watchlist but evaluated the additional public health risk posed by the variant as "low" at the global level in a late June report, in which it also advised that currently approved COVID-19 vaccines are "expected to remain effective to this variant against symptomatic and severe disease." Here's what we know about XFG. What is COVID variant XFG? XFG is a combination of COVID-19 variants F.7 and LP.8.1.2, the latter of which is currently the second most prominent strain in the U.S. The variant's mutations may enhance XFG's ability to evade immune responses, but its binding behavior shows that it is less likely to be highly contagious than other dominant variants, Subhash Verma, microbiology and immunology professor at the University of Nevada, Reno, told USA TODAY. "There is currently no clear evidence that XFG causes more severe disease or significantly different symptoms than earlier Omicron variants," said Verma. "Importantly, there are no immediate public health concerns associated with this variant." How common is XFG? While XFG has been growing and spreading worldwide, it has yet to become the predominant source of infection in the United States. The CDC has moved to using longer timeframes for COVID tracking due to low reporting from states. According to the latest data for the two-week period ending June 21, XFG accounted for 14% of U.S. cases, making it the third most-prevalent strain after NB.1.8.1 (43%) and LP.8.1 (31%). The prominence of XFG in the United States significantly increased in the weeks leading up to the last report, accounting for 0% of cases through March before reaching 2% in April, 6% in late May, 11% in early June and 14% in late June. WHO tracked an uptick in XFG worldwide in June as well, with the June report including data from 38 countries showing that XFG accounted for only 7.4% of positive tests in the first week of May but 22.7% by the last. USA TODAY has reached out to the CDC for more information about the spread of COVID variants in July and August. What are the symptoms of XFG? There is no evidence that XFG causes any distinct symptoms from other variants, said Verma. However, hoarseness has been anecdotally associated with the strain, according to social media posts and news reports. The CDC outlines the following as common COVID-19 symptoms: Fever or chills Cough Shortness of breath or difficulty breathing Sore throat Congestion or a runny nose New loss of taste or smell Fatigue Muscle or body aches Headache Nausea or vomiting The CDC advises seeking medical care if you experience any of the following symptoms: Trouble breathing Persistent pain or pressure in the chest New confusion Inability to wake or stay awake Depending on skin tone, lips, nail beds and skin may appear pale, gray, or blue This article originally appeared on USA TODAY: New COVID variant 'Stratus' spreading in US: symptoms, what to know

Florida snake hunters deploy robotic rabbits to capture invasive Burmese pythons
A team dedicated to controlling populations of invasive Burmese pythons in South Florida has deployed another unique method to find the elusive predators: robotic rabbits. The robots are remote-controlled, solar-powered and designed to look like marsh rabbits, a preferred choice of prey for the pythons, according to the South Florida Water Management District, which is funding the project as part of its Python Elimination Program. Researchers designed the devices to produce a heat signature and emit a smell designed to attract the pythons, according to the utility company. They are also equipped with cameras to monitor for the pythons' movements and alert officials when one is detected -- who can then send out a snake wrangler to detect and euthanize the animals. The robots were strategically placed throughout South Florida, according to the utility company. "We want to capture all of the processes that an actual rabbit would give off," said Robert McCleery, a wildlife ecologist at the University of Florida, told the Palm Beach Post. Scientists at the University of Florida conducted the research, which was partly funded by the FWC. The South Florida Water Management District is funding the experiment. "Our partners have allowed us to trial these things that may sound a little crazy," McCleery said. "Working in the Everglades for ten years, you get tired of documenting the problem. You want to address it." The researchers replaced the stuffing in 40 toy rabbits with electrical components powered by solar energy and waterproofed them to withstand the rain and humidity, according to the Post. This isn't the first time snake hunters have used creative means to capture their prey. In 2020, the FWC deployed python-sniffing detector dogs to track pythons in South Florida. In 2022, University of Florida researchers put live rabbits in cages in the Everglades to lure the snakes. Over 90 days, nine rabbit pens lured 22 pythons, leading the snakes to stay in the area for more than an hour on average, according to a state report. Trackers have been placed on dozens of preferred python prey, such as rabbits, raccoons and opossums, which lead snake hunters to the pythons after they've swallowed the prey. Officials around the state pay bounty hunters to help control Burmese python populations and have attached tracking devices to male snakes, which leads them to egg-laying females. The introduction of Burmese pythons has decimated the local ecosystem in South Florida as they breed rapidly and compete with native wildlife for food, according to the U.S. Geological Survey. An estimated 180,000 were brought into the country between 1975 and 2018, according to the U.S. Geological Survey. Many entered the ecosystem through accidental or intentional release. As of 2000, the species had established a self-sustaining breeding population in the South Florida ecosystem, according to the USGS. The species is now distributed across more than 1,000 square miles of South Florida, including all of the Everglades National Park and across the southern coast to Rookery Bay National Estuarine Research Reserve, according to the USGS. But Burmese pythons are notoriously difficult to detect and capture, experts say. Detectability of Burmese pythons is an estimated 1% to 3%, meaning out of 100 snakes in a survey area, there could be a chance of spotting between one and three individuals, research has shown. At Everglades National Park, the frequency of Burmese python detection is about one python per eight hours of searching, according to the U.S. Fish and Wildlife Service. The U.S. banned the import of Burmese pythons in 2012. But chances of eradication are likely low at this point, according to the USGS. At least 76 prey species have been found in the guts of Burmese pythons over the past several decades, including mammals, birds, iguanas and alligators, according to USGS scientists. A 2012 study found that raccoon populations in the state had declined 99.3% since 1997, while opossums saw a decline of 98.9% and bobcats an 87.5% decline. Marsh rabbits, cottontail rabbits and foxes have effectively disappeared, a 2015 study found. In December 2022, a group of biologists stumbled upon a nearly 15-foot Burmese python in the midst of devouring an adult white-tailed deer. Black rats seem to be the only species of mammal resistant to the pythons. Also an invasive species, they arrived centuries ago aboard ships from Europe. They reproduce quickly and can scavenge carcasses as well as eat plants, insects and scraps from humans -- allowing them to thrive, according to the USGS. But native predators may be starting to fight back, according to researchers who have documented cases of alligators, cottonmouth snakes and bobcats killing Burmese pythons.

Russia's major earthquake prompts string of 7 volcanic eruptions
The massive magnitude 8.8 earthquake that struck off Russia's Kamchatka Peninsula last week has triggered the activity of seven volcanoes in the area, according to the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences (RAS). The RAS said this is the first time in almost 300 years that seven volcanoes erupted at once in the region. Director of the institute Alexey Ozerov described the situation as an "extremely rare phenomenon that can be described as a parade of volcanic eruptions." The magnitude 8.8 earthquake that struck late on July 29 caused several aftershocks, including a magnitude 6 aftershock in the Pacific Ocean near Kamchatka at 6 a.m. local time Tuesday morning, according to the Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences. Among those erupting is the Klyuchevskoy Volcano, which the Kamchatka Volcanic Eruption Response Team reported to be spewing ash on Tuesday. The earthquake on July 29 has now caused the southern part of the Kamchatka Peninsula to shift southeastward, according to the local branch of the Russian Academy of Sciences' Unified Geophysical Service. The Kamchatka branch of the Federal Research Center "United Geophysical Service of the Russian Academy of Sciences have calculated the surface of the Earth shifted to the southeast, with the greatest shift occurred in the south of the peninsula reaching almost 2 meters. The greatest shift occurred in the south of the peninsula, movement that is comparable to the horizontal displacement that resulted from the 2011 earthquake in Japan. Seismologists acknowledge the peninsula has "shifted somewhat more modestly" although they do not specify the exact amount. The eruptions follow the volcanic activity of the Krasheninnikov Volcano that saw lava flow in the last week for the first time in nearly 600 years. Local officials said the last lava flow was recorded in 1463. A Russian seismologist told local media that there is a direct connection between last week's powerful earthquake and increased volcanic activity in Kamchatka. "We attribute the eruptions to the earthquake, which activated the magmatic foci and provided them with additional energy," Alexey Ozerov, a corresponding member of the Russian Academy of Sciences and director of the Institute of Volcanology and Seismology, told TASS, a state-affiliated media in Russia. The Krasheninnikov volcano is located less than 150 miles away from the epicenter of the earthquake that struck off the east coast of the Russian peninsula on July 29. The intense quake was one of the most powerful earthquakes ever recorded, and the world's largest since 2011. It spurred tsunmai warnings from Japan to Hawaii and the West Coast of the United States. Volcanic activity is common for the Kamchatka Peninsula, which is home to 29 active volcanoes, according to the U.S. Geological Survey, with three of those currently erupting previously laying dormant according to the RAS Massive eruptions began at 6 a.m. local time on Sunday, prompting the evacuation of personnel in the area, according to the Kronotsky Nature Reserve's website. The regional Ministry of Emergency Situations said there are no settlements along the ash plume's path of the Klyuchevskoy and said there are no registered tourist groups in the volcano's vicinity.
