A volcano in northwest Costa Rica erupted on Monday, spewing an enormous column of smoke into the air in what could be its biggest outburst in years, authorities said.
The Rincon de la Vieja volcano’s nearly three-minute eruption in the early hours of the day belched a column of smoke almost two kilometers (1.2 miles) high, depositing ash on surrounding areas but causing no damage or injuries.
The volcano, whose eruption did not trigger any immediate evacuations, is situated in a national park in Guanacaste province some 200 kilometers from the capital, San Jose.
“It was a pretty energetic eruption,” said Maarten de Moor, a specialist at the Volcanological and Seismological Observatory of Costa Rica (Ovsicori).
Although the volcano has frequent outbursts — some 1,400 last year alone — this “could be the largest since the 1990s,” he added.
The National Commission for Risk Prevention and Emergency Management said it had deployed a team to evaluate the situation, and urged people not to approach the site.
Costa Rica has five active volcanos.

Residents were told to evacuate from 10 neighborhoods in Goma, in the Democratic Republic of Congo, on May 27, due to the threat of another volcanic eruption and repeated earthquakes.
This footage, by Elie Kasereka, shows a long line of traffic as people leave the city.
The evacuation comes in the wake of the eruption of Mount Nyiragongo on May 22, which killed at least 32 people and prompted tens of thousands of people to flee.
The Red Cross in Africa said it was helping to reunite families after 300 children were separated from their parents in the wake of the eruption.

Scientists have downgraded the alert level at Great Sitkin Volcano near the Aleutian Island of Adak following an eruption Tuesday night.
The event took place at around 9 p.m. and produced an ash cloud up to 15,000 feet above sea level and impacted flights.
“The eruption itself occurred for over about a minute,” said David Fee, coordinating scientist for the Alaska Volcano Observatory. “It had a very loud, audible and low frequency sound to it. I guess a good analogy would be if you shake up a bottle and then you pop the cork and get an explosion out the top. That’s kind of what happened here.”
Following the eruption, Fee said, they issued a red alert warning for planes in the area, because there was likely a high emission of volcanic ash in the atmosphere.
“We lowered the advisory back down to orange this morning,” Fee told KUCB Wednesday morning. “And there hasn’t been much activity — I think it’s mainly just steaming since the eruption last night.”
According to Fee, the activity at Great Sitkin isn’t “normal,” but it’s also not unexpected, given some small explosions that have happened there over the past few years.
He said the volcano observatory will continue to watch closely for increased seismic activity or gas emissions that could indicate another eruption, but for now, it’s pretty quiet.
“We haven’t seen an eruption like this from Great Sitkin at least as long as I’ve been around here,” he said. “So it could quiet down or we could expect continued activity. We’ll just have to wait and see.”
This is the first significant explosion at Great Sitkin since 1974.

The Trinidad-based Seismic Research Centre (SRC) of the University of the West Indies (UWI) today reported a “large explosion” at the La Soufriere volcano.
In a brief update posted on its website, the SRC said that its team monitoring the volcano, which erupted last Friday, “has observed a large explosion at approximately 4:15 am (local time) and pyroclastic density currents(flows) have been observed on the flanks of the volcano”.
The SRC said that it is continuing to monitor the situation and will update later.
Volcanologist Professor Richard Robertson yesterday warned that the ongoing eruption of La Soufriere volcano is in keeping with the events surrounding the 1902 eruption which claimed 1,600 lives at a time when early warning systems and evacuation capabilities were not as advanced.
Speaking on the state-owned NBC Radio, Professor Robertson, the lead scientist monitoring the volcano, said that while most people know of the 1979 eruption, what is currently happening at La Soufriere is more akin to more a century ago.
“The activity pattern we have currently is more similar to a 1902 type of eruption of that kind of scale, rather than a 1979 scale. The people who lived through 1979 know the kind of eruption we have had.
“What does that mean? It means, unfortunately, that it is likely going to cause more damage and destruction to St Vincent but it also means that there will always be a safe place in the south of the country, which might have a lot of ash every now and then, but you can still sustain life and limb and it would not — which is what we all worry about — get so big that it destroys the whole country. That currently doesn’t seem to be the case.”

34 earthquakes rattle Mauna Loa, world’s largest active volcano, Hawaii and scientists say eruption is possible
The Big Island of Hawaii, home to the world’s largest active volcano, Mauna Loa, was rocked by 34 earthquakes on Sunday. While most of the earthquakes were low in magnitude, and none were strong enough to cause a tsunami, scientists warned citizens that an eruption from Mauna Loa could be possible in the near future.
“While an eruption of Mauna Loa is not imminent, now is the time to revisit personal eruption plans,” said a recent press release from scientists with the Hawaiian Volcano Observatory. “Similar to preparing for hurricane season, having an eruption plan in advance helps during an emergency.”
The largest active volcano on Earth, Mauna Loa reaches a height of 13,681 feet above sea level, and 3 miles below the Central Pacific to the ocean floor. “Mauna Loa” is Hawaiian for “Long Mountain.” The volcano covers half of the island.
The Big Island of Hawaii is also home to three other active volcanoes: Kilauea, Mauna Kea and Hualalai. Kilauea has been erupting since December.
Concern from scientists stems from the rate at which deformation, or changes to the volcano’s surface, are affecting Mauna Loa, as well as its seismicity, or the frequency of earthquakes. The Big Island has had more than 744 earthquakes in the last of a magnitude 1.5 or greater in the last 30 days.
U.S. Geological Survey scientists recommended residents have response plans and a “go-bag” ready in the case of an evacuation order.
“Nowadays, people pack ‘go’ bags containing essential items in case you have to leave your house under an evacuation order,” the USGS said. “You may want to include important documents, like your birth certificate, deeds, legal papers, and medications.”
According to the Hawaiian Volcano Observatory, Mauna Loa has erupted 33 times since 1843. Its last eruption lasted from March 25 to April 15, 1984.

The Barbados Meteorological Services issued a severe volcanic ash warning for the island on April 10, 2021. A thick plume of volcanic ash from the La Soufriere Volcano in St Vincent, which erupted on April 9, is currently affecting the island. Satellite imagery of the volcano continues to show a thick plume of ash traveling easterly towards Barbados. There have been reports of ash fall across the island, and Saharan dust haze also remains present, which will continue to reduce visibility and may cause respiratory problems, especially for those persons with pre-existing respiratory issues or allergies.
The Grantley Adams International Airport in Barbados is closed until at least 6 a.m. on April 11, 2021, due to the volcanic ash.
Actions to Take:
Remain vigilant and maintain active awareness of local conditions.
Limit outdoor activity and wear masks (N95 ideally) when outdoors
Close windows and use air filters if available indoors.
Persons with respiratory issues or allergies should ensure they have, close at hand, all prescribed relevant medications and inhalers in case of an emergency.
Use car headlights to assist with the reduced visibility and do not use the car’s ventilation system.
Monitor the Barbados Meteorological Services website for updates.
