How a thermophilic bacterium from a Yellowstone hot spring is helping the fight against the COVID-19 pandemic.
March 30, 2020

Epidemiologists are working around the clock to understand and learn how to best fight the virus named COVID-19 (aka, the coronavirus), while the healthcare system is doing its best to take care of those made sick by the virus. Over the past few months, the world has taken unprecedented measures to stop the spread of the virus; understanding how it spreads is critical as well. And this is where Yellowstone enters the picture. We would not be able to test for the COVID-19 virus without microbes from Yellowstone hot springs!

YVO continues work amid COVID-19
March 24, 2020

The Yellowstone Volcano Observatory continues to monitor volcanoes and issue monthly updates of volcanic activity. Through telework and other adaptations the USGS and YVO partner agencies continue to maintain our monitoring networks and analyze the incoming data. Our field crews visit field stations as needed to maintain the quality and functionality of the network. All work will follow federal government guidelines to ensure public safety and the safety of our staff. The health and safety of the public and our employees are our highest priorities, and we continue to follow guidance from the White House, the CDC, and state and local authorities, as we implement teleworking, social distancing and virtual meeting tools.

Our priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices. If you need additional assistance, please contact yvowebteam@usgs.gov.


Steamboat Counter
May 14, 2018

Steamboat Geyser, in the Norris Geyser Basin, appears to have entered a phase of more frequent water eruptions, much like it did in the 1960s and early 1980s. Although these eruptions do not have any implications for future volcanic activity at Yellowstone (after all, geysers are supposed to erupt, and most are erratic, like Steamboat), they are nonetheless spectacular, and many people had a chance to see Steamboat in eruption during the summers of 2018 and 2019.

To keep track of the geysering, we will keep an updated count of Steamboat water eruptions on this page. In 2018, Steamboat erupted 32 times -- a new record for a single calendar year! That record was shattered in 2019 with 48 eruptions. So far the geyser has erupted 9 times in 2020. All times below are local.

Would you like to become a Steamboat watcher? If so, there are three datasets to keep an eye on:
  1. Seismic station YNM, in the Norris museum, is the first indicator of an eruption. The webicorder for the station is located here. Look for a thick seismic trace that lasts 30-60 minutes.
  2. About 90 minutes after eruption, increased discharge can often be seen at the Tantalus stream gage. You can get that information here. Scroll down to the plot "Discharge, cubic feet per second" and look for a spike and subsequent decay, but be careful...precipitation can cause spikes too! Rainfall information is given in another plot on that page.
  3. Each night, temperature data from a sensor in the Steamboat drainage channel is downloaded and posted on line. A sudden and short-lived (minutes-long) spike in temperature indicates a Steamboat eruption. To view those data, go to the YVO monitoring map and zoom in on the Norris area. Hover over any of the thermometer symbols to see their names, and click on the one labeled "Steamboat" to see data from various time periods past.

Have fun! You might also check out the Steamboat page at geysertimes.org for information about Steamboat activity.
