Yellowstone volcano activity

Scientists who work at Yellowstone are interested in finding physical and chemical signals from the deep magmatic system, both to better understand the nature of the system and also to monitor for possible changes. Some of that research involves collection and analyses of gas and water from thermal areas to look for chemical tracers that can be directly linked to the magma. This includes Helium, which has two different forms. One form is created by the radioactive breakdown of elements in Earth’s crust, but the other is supplied from the mantle by volcanic activity. Measuring helium in Yellowstone therefore provides a window to the mantle!

Find out more about the various forms of helium and what they mean in this week’s Yellowstone Caldera Chronicles! YVO monthly video update for August 1, 2019

Check out the YVO monthly video update for August 1, 2019! This month’s report covers the 60th anniversary of the M7.3 Hebgen Lake earthquake, which occurred on August 17, 1959, as well as seismic and deformation data, and eruptions of Steamboat geyser.

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 summer of 2018 and now in the summer of 2019 as well.

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!), and so far the geyser has erupted 31 times in 2019. 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.
