    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

    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.

    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.
