Yellowstone — the year 2018 in review
Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory.
Which U.S. volcanoes pose a threat?

Where hot and cold water meet: a study of LaDuke Hot Springs using UAVs and field observations
Just a few miles north of Yellowstone National Park, discharge from a sizable hydrothermal feature, LaDuke Hot Springs, mixes with the Yellowstone River.
A closer look at the 2017 Maple Creek earthquake swarm
In June of 2017, an earthquake swarm began beneath the western edge of Yellowstone National Park, just east of Hebgen Lake. This swarm proved to be one of the more persistent swarms observed in Yellowstone, with the main episode lasting more than 3 months and producing thousands of recorded earthquakes.
The Hydrothermal System in Yellowstone Lake
When you think of a lake bed, what comes to mind? Squishy bottom with some grasses, rocks, and sunken logs?
Can a nuclear blast trigger a Yellowstone eruption? No. But how about an earthquake? Also no.
YVO has noted, with some amusement, tabloid headlines about various diabolical schemes to trigger an eruption of Yellowstone by nuking the caldera. If you find these crazy schemes somewhat unnerving, please don't be concerned—such a plan has zero chance of working!
A DIY guide for Yellowstone GPS data
Yellowstone is an incredibly dynamic place—there are frequent earthquakes, geysers erupt and go dormant, and the ground moves up and down. As seasoned Yellowstone watchers know, all...
The Misadventures of E.C. Waters -- the man and the boat!
"E.C. Waters, president of the Yellowstone Lake Boat Company, having rendered himself obnoxious during the season of 1907, is...debarred from the park and will not be allowed to return without permission in writing from the Secretary of the Interior or the superintendent of the park."
(Posted by Yellowstone National Park Superintendent Samuel Young in 1907)
Check out research in Yellowstone's Upper Geyser Basin this week—LIVE!
Have you ever witnessed an Old Faithful Geyser eruption and wondered how it works? What hidden underground environment causes thousands of gallons of water to burst skyward? Why does the geyser behave so faithfully? And how does the geologic history of the Upper Geyser Basin play a role in the extraordinary geyser activity we see today?
The USGS volcano threat assessment -- how was it determined, and what does it mean for Yellowstone
Last week, the USGS released an updated threat assessment for US volcanoes. The first assessment was published in 2005. The 2018 update refined the original assessment by accounting for new research & observations over the past 13 years. Some volcanoes moved up...
Volcanic Threat Assessment help prioritize risk reduction efforts at U.S. volcanoes
Since 1980, there have been 120 eruptions and 52 episodes of notable volcanic unrest at 44 U.S. volcanoes.
Volcanic Threat Assessment help prioritize risk reduction efforts at U.S. volcanoes.
The USGS assesses active and potentially active volcanoes in the U.S., focusing on history, hazards and the exposure of people, property and infrastructure to harm during the next eruption.
