    BOZEMAN, Mont. (AP) — A thermal spring near Old Faithful in Yellowstone National Park has erupted for the fourth time in the last 60 years, a park official said Thursday.

    Ear Spring on Yellowstone's Geyser Hill went from being dormant on Saturday to spewing steam and water between 20 and 30 feet (6 and 9 meters) high, a height not recorded since 1957, said park spokesman Neal Herbert. It has since continued to erupt at a near-constant height of about 2 feet (0.6 meters), he said.

    Ear Spring, named for its resemblance to the shape of a human ear, is one of dozens of geysers, pools and hot springs in Yellowstone's Upper Geyser Basin — among the park's top attractions that feature the popular Old Faithful. It last erupted in 2004.

    The eruption is among the new thermal activity seen over the last several days on Geyser Hill, just across the Firehole River from Old Faithful.

    The activity includes new erupting vents and surface fractures, and it has led park officials to close a boardwalk in the popular Upper Geyser Basin to prevent people from being injured by scalding water splashing on the popular boardwalk trail.

    Yellowstone's thermal basins sometimes undergo significant changes in short amounts of time, but the new eruptions are not a sign of impending volcanic activity, Herbert said.

    The changes are continuing and could lead to new or different closures in the basin, he said.

    "It's still in flux," Herbert said. "There is still water flowing in new places and some of the springs that had been dormant have been erupting nearly constantly."

    Ear Spring isn't the first dormant geyser to come to life this year. In March, the world's largest active geyser began the first in a series of eruptions for the first time since 2014.

    Steamboat geyser's eruptions can reach heights of 300 to 400 feet (91 meters to 122 meters), compared to Old Faithful's 130-foot (40-meter) average.

    Yellowstone VOLCANO LATEST: Geysers shooting ROCKS and steam - thermal activity INCREASES
    https://www.express.co.uk/news/world/1020357/yellowstone-volcano-eruption-geysers-earthquake-thermal-activity

    YELLOWSTONE’S Upper Geyser Basin is showing increased signs of thermal activity, after hot plumes of water erupted from the ground several feet up in the air, forcing authorities to shut down parts of the park over fear of new geysers forming.

    Yellowstone volcano: Old Faithful geyser erupts with steam

    New vents were seen blasting water and steam across the basin area in Geyser Hill, ever since the Ear Spring erupted on Saturday.

    Authorities have attributed the rise in geothermal activity to Saturday's eruption, after several new surface fractures and splashes of water were spotted at the Upper Geyser Basin in Yellowstone National Park.

    On Tuesday, spouts of water shot from the ground west of Pump Geyser and north of Sponge Geyser, also ejecting large amounts of hot steam.

    The new feature, which is eight-foot diameter, continues to show increased signs of activity after geologists observed the ground rising and falling by six inches every 10 minutes.

    Geologists have also observed new geysering and boiling at hot spring Doublet Pool and North Goggles Geyser, located in the Upper Geyser Basin.

    Officials have warned visitors to beware of new eruptions and have closed down several parts of the basin as they continue to study the rare change in the area's activity.

    On Saturday, Ear Spring erupted plumes of water up to 30 feet in the air, endangering visitors as debris and rocks flew into the sky.

    The last known eruption on that scale occurred in 1957, though several smaller eruptions were observed in 2004.

    Ear Spring is one of the hottest pools in Yellowstone National Park and contains water above the boiling point up to 200 degrees.

    Geyser Hill lies across the Firehole River from Old Faithful and features dozens of hot springs, geysers and fumaroles.

    Authorities believe the change in hydrothermal activity in the area could bring a rise to new geysers or cause further road blocks over fears thermally heated grounds will expand.

    Activity in Upper Geyser Basin will not have a direct impact on other geysers, such as the famous Old Faithful.

    However, geologists say the new geothermal eruptions are common occurrences, and will not bring rise to new volcanic activity.

    The Yellowstone Volcano Observatory said: "Changes in Yellowstone's hydrothermal features are common occurrences and do not reflect changes in activity of the Yellowstone volcano.

    "Shifts in hydrothermal systems occur only the upper few hundred feet of the Earth's crust and are not directly related to movement of magma several kilometres deep. There are no signs of impending volcanic activity.

    "There has been no significant increase in seismicity nor broad-scale variations in ground movement."

    Experts have warned earthquakes at Yellowstone are more likely to occur than volcanic eruptions.

    Michael Poland, the chief scientist in charge of the Yellowstone Volcano Observatory said: “The biggest concern we have for Yellowstone is not with the volcano, it’s with earthquakes.

    “This is an under-appreciated hazard in the Yellowstone area. There can and will be in the future magnitude 7 earthquakes.”

    The US National Parks Service said: “Yellowstone commonly experiences ‘earthquake swarms’ – a series of earthquakes over a short period of time in a localised area.

    Yellowstone Volcano: Is Eruption Imminent After 193 Earthquakes in a Month
    All the tremors were small with the largest registering 3. The Park has about 700 in a year. This might be a part of a natural cycle.

    Huge chunk of Yellowstone National Park, the size of Chicago,
    is 'breathing' in and out due to magma trapped underneath the surface


    An area at the center of the Norris Geyser Basin was found to inflate and deflate
    Experts have determined a intrusion of magma under the surface is to blame
    Magma became trapped at the top and pushed the rocks up above it
    The magma has since receded, putting the pulsating on pause for now

    An area the size of Chicago in Yellowstone National Park has been inflating and deflating by several inches over the past decade

    The Norris Geyser Basin, the oldest, hottest and most dynamic thermal area in the park, was observed to rise 5.9 inches each year from 2013 to 2015 - an unusual event that left researchers baffled.

    Now, using satellite radar and GPS data, experts have determined the ground deformation was caused by magma intrusions trapped below the basin's surface.

    As magma made its way to the surface, the pressure pushed rocks above it up and created an erratic pulsating effect, according to National Geographic.


    This is the first time the scientific community has been able to track an entire episode of magma intrusion, which they say is a common occurrence throughout Yellowstone.

    Yellowstone National Park sits in the northwest region of Wyoming and is home to bursting geysers, steam vents and bubbling pools.

    At 3,472 square miles, the park is larger than the states of Rhode Island and Delaware combined.

    Most of the land is in Wyoming, but some of the park spills over into Montana and Idaho.

    Below the park is a 'supervolcano' that scientists believe last erupted some 640,000 years ago, but the new study shows there is still magma flowing beneath the surface.

    As the magma made its way to the surface, the pressure pushed the rocks up above it and created an erratic pulsating effect

    The uplift at Norris Geyser first began in 1996, but came to halt between 2013 and 2014 after a magnitude 4.9 earthquake struck the area.

    Following the natural event, the ground started to sink back to its natural depth.

    However, data shows that the rise began again in 2016 and continued two years after – researches believe it has paused for now.

    Dan Dzurisin, one of the study authors, wrote in the study: 'Modeling...suggests the 1996–2004 uplift was caused by an intrusion of magma about 14 km [8.7 miles] beneath Norris.'

    'When magma intrudes the crust it cools, crystallizes, and releases gases that had been dissolved in the melt.

    'Gas escape lowers pressure in the magma, causing the surface to subside... But rising gases can become trapped under an impermeable layer of rock, causing the kind of rapid uplift seen at Norris from late 2013 until the [magnitude] 4.9 earthquake in March 2014.'

    'It seems likely the quake created microfractures that allowed gases to escape upward again, resulting in subsidence that ended in 2015.

    'The third uplift episode from 2016 to 2018 suggests rising gases became trapped again, this time at a slightly shallower depth.'

    Dzurisin also noted in the study that this type of activity is common throughout the park and does not send off any alarm bells, Newsweek reported.

    'For the first time, we've been able to track an entire episode of magma intrusion, degassing, and gas ascent to the near-surface. For those in the know, like you, that's awesome—not alarming,' he explained.

    These finding have also led researches to clues about Steamboat Geyser's (pictured) increase in activity over the past two years. It 47 times this year – compared to the 32 times in 2018

    These finding have also led researches to clues about Steamboat Geyser's increase in activity over the past two years.

    'Frequent eruptions of Steamboat Geyser since March 2018 are likely a surface manifestation of this ongoing process,' reads the study.

    'Hydrothermal explosion features are prominent in the Norris Geyser Basin area, and the apparent shallow nature of the volatile accumulation implies an increased risk of hydrothermal explosions.'

    The Steamboat Geyser in Yellowstone National Park, Wyoming erupted 47 times this year – compared to the 32 times in 2018.

    Scientists speculated that the eruptions are related to heavy snows in Yellowstone, which created more groundwater to feed geysers and hot springs.

    Steamboat has the accolade as the world's largest geyser but is somewhat overshadowed by the fame and popularity of Old Faithful in the national park.

    Erin White, Yellowstone National Park's hydrologist, told NPR: 'In the 1960s, there was another period where there were more than 20 eruptions per year.'

    'Prior to that, there were dormant periods of more than 50 years.'

    Steamboat – which can shoot water more than 300 feet into the air - broke a record in August when it erupted for the 33rd time.

    And just when experts thought it could not get any better, the geyser shot off 14 more times, bringing the total number of eruptions this year to 4
    7, according to the US Geological Survey.

    Prior to this year's record the giant geyser had laid dormant, which is why scientists have been baffled by its recent numerous bursts of hot water and steam.
