quote:The Shoshone River, near Yellowstone National Park, suddenly and without warning started boiling, changed color and began to emit a sulfuric odor on March 25. Nearby witnesses wondered if they were “all going to die.” The current consensus among geologists and other experts is that a portion of the Shoshone River began to boil, located near Cody, Wyoming, and a new Yellowstone vent has opened up.

MAMMOTH HOT SPRINGS, Wyo. (AP) — An earthquake shook a backcountry area in the northwest part of Yellowstone National Park on Thursday evening.
The U.S. Geological Survey says the preliminary 4.5 magnitude quake occurred in a backcountry area at 6:48 p.m., about 8 miles northeast of West Yellowstone, Montana.
The West Yellowstone Police Department says the earthquake was felt in the town that borders the park but there were no reports of damage.
The University of Utah Seismograph Stations said the quake was part of "an energetic sequence" of about 30 earthquakes in the area that began on Monday. Thursday's quake was the largest to occur in Yellowstone since a 4.8 magnitude quake in March 2014.
Earthquakes occur frequently in and around Yellowstone.

In het Amerikaanse natuurpark Yellowstone is de 21-jarige Gervais Dylan Gatete zwaar verbrand geraakt nadat hij in een van de warmwaterbronnen van het park belandde, zo delen de parkautoriteiten mee.
Het incident vond dinsdagavond plaats. Gatete bevond zich samen met zeven andere mensen in de omgeving van de bron. De groep probeerde de man hield vervolgens per auto naar het ziekenhuis over te brengen, maar hield omstreeks middernacht een wagen met parkwachters tegen om om hulp te vragen. Gatete, die werkt voor een van de hotels in het park, werd overgevlogen naar het ziekenhuis van Salt Lake City. Zijn toestand is stabiel.
Onderzoekers proberen nu te weten te komen hoe Gatete precies in het water is beland.
Sommige warmwaterbronnen in het park bereiken een temperatuur van zo'n 100 graden Celsius. Dan Wenk, de hoofdopzichter van het park, laat in een verklaring weten dat de vele bronnen in het park erg gevaarlijk zijn en dat de grond eromheen fragiel en dun is: het kokend hete water bevindt zich net onder de oppervlakte. "We beklemtonen voortdurend dat mensen op de wandelpaden en houten paden moeten blijven. Niet alleen om de natuur te beschermen, maar ook voor hun eigen veiligheid," luidt het.
quote:Supervolcano hit by earthquake swarm
Yellowstone supervolcano has been hit by a series of earthquakes, with more 400 recorded since June 12. The latest was recorded on Monday, June 19, with a magnitude 3 earthquake striking 8.6 miles north northeast of West Yellowstone, Montana.
The swarm began last week, and on June 15 saw a magnitude 4.5 earthquake take place in Yellowstone National Park. “The epicenter of the shock was located in Yellowstone National Park, eight miles north-northeast of the town of West Yellowstone, Montana,” scientists from the University of Utah, which monitors Yellowstone Volcano, said in a statement.
“The earthquake was [reportedly] felt in the towns of West Yellowstone and Gardiner, Montana, in Yellowstone National Park, and elsewhere in the surrounding region.”

This earthquake was the largest to have hit Yellowstone since March 30, 2014, when a magnitude 4.8 earthquake was recorded 18 miles to the east, near the Norris Geyser Basin.
“[The 4.5] earthquake is part of an energetic sequence of earthquakes in the same area that began on June 12,” the statement continued. “This sequence has included approximately thirty earthquakes of magnitude 2 and larger and four earthquakes of magnitude 3 and larger, including today's magnitude 4.5 event.”
As of June 19, 464 events had been recorded. Most of these ranged in the magnitude of 0 to 1, with five less than zero, indicating they occurred at depths ranging from about 0 miles to about 9 miles. "This is the highest number of earthquakes at Yellowstone within a single week in the past five years, but is fewer than weekly counts during similar earthquakes swarms in 2002, 2004, 2008 and 2010," scientists said.
The University of Utah is part of the Yellowstone Volcano Observatory (YVO), which monitors volcanic and earthquake activity in Yellowstone National Park. Seismic activity at volcanoes can signal an eruption is due to take place, although predicting exactly when a volcano will erupt is, at present, impossible.
Experts at the U.S. Geological Survey (USGS) say the risk of an eruption at Yellowstone supervolcano is low—the current volcano alert level remains normal and the aviation color code, which provides information on the potential risk to fights, is green—meaning the volcano is in a normal, non-eruptive state.
A spokesperson from the USGS and YVO tells Newsweek the current activity appears to be “slowly winding down” and that “no other geological activity has been detected.”
The probability of a large eruption at Yellowstone in the next year is currently calculated at one in 730,000.

A strong earthquake with a preliminary magnitude of 5.8 has struck western Montana, with shaking felt as far away as Idaho, Washington, and Canada, seismologists say. Only few details were immediately available. (more)
The earthquake, which struck at 12:30 a.m. MT on Thursday, was centered about 5.9 miles southeast of the town of Lincoln, which is located in Lewis and Clark County. It is about 33 miles northwest of Helena and roughly 65 miles from Butte and Missoula.
The U.S. Geological Survey (USGS) put the preliminary magnitude of Thursday's earthquake at 5.8, making it a fairly strong earthquake. It said the earthquake struck at a depth of just 2 miles, which will have increased the intensity of the shaking.
Witnesses across a number of states reported feeling the earthquake, including in Missoula and Butte in Montana. Shaking was also reported in North Dakota, South Dakota, Wyoming, Idaho, Washington state, and across the border in Canada.
