The 3,340-meter Turrialba Volcano is located in Cartago Province of central Costa Rica, only 30 km from the country's capital, San José. The volcanic activity started Wednesday and the first eruptions were recorded Friday, according to local media.
Growing up to eight metres long, the oarfish is known to float vertically in the water at depths of up to 300m, and usually only in tropical locations.
One was found in Dunedin last year, but sightings of them in New Zealand were few and far between.
Identifiable by their long flat bodies and red dorsal fin, the oarfish was an edible game fish, but their meat was jelly-like and not regarded as very good eating.

Landslides and flooding caused by torrential downpours have killed at least 71 people as rescuers search for more than a hundred people still missing, Sri Lanka's Disaster Management Center (DMC) said on Saturday.
A half a million people have been displaced by a week of heavy rains caused by Cyclone Roanu, which after passing through Sri Lanka continued on a destructive path towards low-lying Bangladesh.
Roanu battered Bangladesh's coastline on Saturday, killing at least 20 people and displacing nearly a half a million. Hundreds of mud and tin homes in the impoverished nation were destroyed.
"They didn't swim from Africa," University of Florida herpetologist Kenneth Krysko, who co-wrote a study confirming the arrival of the crocs, told the Associated Press."But we really don't know how they got into the wild."
Over the course of their study, Krysko and his team analyzed the DNA of three crocodiles that were caught in Florida in 2009, 2011 and 2014. Their results found that two of the reptiles matched up almost perfectly with native Nile crocodiles from Africa, while the third one was also related.
Additionally, all three crocodiles may have been introduced to the environment through the same source - possibly an illegal reptile collector who lost control of the animals.
Notably, the scientists believe that it's possible more Nile crocs are still out in the Florida wild.
The first earthquake, which has a preliminary magnitude of 4.8, was centered about 16 kilometers south of Vraneštica, or some 85 kilometers southwest of Skopje. It struck at a depth of 10 kilometers, making it a shallow earthquake.
About 8 minutes later, the same region was shaken by a slightly stronger earthquake with a preliminary magnitude of 4.9, according to the European-Mediterranean Seismological Center. It said the second earthquake struck closer to the surface, at a depth of just 5 kilometers.
The earthquakes were felt throughout the region, according to residents, but there were no immediate reports of damage or casualties. "It was loud and pretty strong," a resident in Resen in Macedonia reported.
In Skopje, one resident reported that doors and lights began to sway.
The highly active Mount Sinabung on the island of Sumatra spewed gas and ash high into the atmosphere and surrounding area on Saturday.
The three farmers were killed inside the prohibited "red zone" near the slopes of the volcano, Indonesia's disaster agency said.
"This area should have been empty, because nobody should be inside the red zone," disaster agency spokesman Sutopo Purwo Nugroho said.
The 2,600 meter (8,530 feet) high volcano sprung back to life in 2010 after lying dormant for nearly four centuries.

Four elephants, including two calves, were killed by lightning in northern Sri Lanka in one of the worst wildlife tragedies to hit the country in years.
A female elephant, aged about 25 years, and two of her calves, aged 10 months and two years, and an eight-year-old female were found dead Sunday just outside the Wilpattu wildlife sanctuary, an official said.
"Villagers from neighbouring areas alerted the authorities and we carried out autopsies," wildlife veterinary surgeon Chandana Jayasinghe said. "The deaths were caused by lightning."
Local villagers in Mahavilachchiya, 250 kilometres (156 miles) north of Colombo, had reported heavy rains accompanied by thunder and lightning in the shrub jungle area on Friday when the elephants were thought to have been struck.
It was the worst natural disaster involving elephants since February 2011 when four baby elephants drowned in a major flood in the north-east of the country.

Owner of the pachyderm, Winai Sroysaeng, 27, said the 10-year-old cow named Hongyok was carrying two Chinese tourists when the jumbo went on a rampage and ran towards the mahout, who was taking photos of tourists.
The man flew about 5 meters and the elephant then stomped on him, leading to massive internal injuries. The two tourists fell off and sustained minor injuries.
Winai said Hongyok usually was a peaceful elephant and had never exhibited bad behavior before. He suspects the jumbo was agitated by the heat.
Police ordered the elephant camp to keep the pachyderm away from people until it could be examined by a specialist.
