Volcanic activity occurring all around the world
Dec. 6 (UPI) -- As Hawaii's Mauna Loa and neighboring Kilauea volcanos simultaneously erupt, drawing worldwide attention, geologists continue to monitor dozens what are called "continuing volcanic eruptions" around the globe.
Currently, 47 volcanoes fit that definition according to the Smithsonian Institution's Global Volcanism Program. Of those, generally about 20 actively erupt on any given day, according to program data.
A volcano in a continuing eruption phase may not be erupting every day, but maybe once a week, or every few days, so on any particular day there are around 20 actively having explosions or lava flows," said Ed Venzke, editor-in-chief of the Bulletin of the Global Volcanism Network.
Most of the continuously erupting volcanos are clustered around what is called the "Ring of Fire," which circles the Pacific Ocean. According to the United States Geological Survey, most earthquakes and volcanic eruptions occur where the Pacific Plate meets many surrounding tectonic plates. The "Ring of Fire" is the most seismically and volcanically active zone in the world.
Mauna Loa and Kilauea are currently erupting at the same time for the first time since 1984. They are just two of the 47 active volcanos actively erupting around the world. Mauna Loa, which is the largest active volcano on Earth, is erupting for the first time in 38 years. Kilauea was already active.
On Tuesday, Hawaii deployed the National Guard, as Mauna Loa's lava flow moved closer to the Daniel K. Inouye Highway two weeks after it started erupting.
" Lava diversion is a tricky thing to do, especially on flat ground," said Hawaii County Civil Defense Administrator Talmadge Magnoe. "It really comes down to a volume problem. What we're seeing now is -- take 10 of the biggest dump trucks you can think of, we're getting that many dump trucks of lava every second delivered by this lava flow ."
In addition to Mauna Loa and Kilauea, there are two other volcanoes currently erupting in the United States. Pavlof Volcano in Alaska has been venting gas and ash as high as 20,000 feet since last month and Alaska's Volcano Observatory has also reported a slow lava effusion from Great Sitkin since the end of November.
"A total of 10,000 cloth masks, 10,000 medical masks and 4,000 children's masks have been distributed to reduce the impact of respiratory health risks due to volcanic ash," Indonesia's National Disaster Management Agency said in a statement .
Mount Semeru is one of eight volcanoes currently erupting in Indonesia. The others include Mounts Kerinci, Krakatau, Merapi, Lewotolok, Karangetang, Ibu and Dukono.
Mount Semeru, which is located on the island of Java, is Indonesia's highest volcano and last erupted a year ago, killing 51 people. There were no casualties in Sunday's eruption. Geologists blame monsoon rains that eroded the volcano's lava dome for causing the eruption.
Italy's National Institute of Geophysics and Volcanology recorded a lava flow leading from the northern crater of the volcano which oozed out to the Tyrrhenian Sea through a fissure in the earth's crust known as the Sciara del Fuoco or "stream of fire."
The Stromboli volcano erupted seven times in 2022. Mount Etna, another active volcano located on the Sicilian mainland, erupted in February and May of this year, but its nine-year eruption ended. However on Nov. 27, a small flank vent opened and is feeding a small lava flow, according to Smithsonian officials.
On Saturday, Sakurajima volcano on Kyushu in Japan erupted with a spectacular show of lightning, lava and ash that spewed 6,000 feet above sea level.
The eruption of Sakurajima is one of three ongoing eruptions in Japan that include Suwanosejima last month. Aira in south Japan has emitted 700 tons of sulfur dioxide each day since Nov. 21 when the volcano exploded, sending an ash plume more than a mile into the air.
Chile's Villarrica volcano, which is the country's most active volcano, erupted Sunday with two explosions and a plume of lava shooting out of the crater.
Chile's Nevados de Chillan was also active in October after an earthquake in the area.
In Russia, the Sheveluch volcano on the Kamchatka Peninsula erupted on Nov. 20, with up to 10 explosions per hour. Sheveluch is one of Kamchatka's largest and most active volcanoes with an estimated 60 large eruptions over the past 10,000 years.
Sheveluch is one of five volcanos currently erupting in Russia, that also include Alaid, Ebeko, Chikurachki and Bezymianny.
Other volcanoes currently erupting around the world can be found in the Philippines, Solomon Islands, Costa Rica, Nicaragua, Ecuador, Tanzania, Peru, Tonga, Australia, Mexico, Guatemala and Ecuador, according to the Smithsonian Institution's Global Volcanism Program.
