Norris Geyser Basin

Steamboat Geyser, in Yellowstone National Park's Norris Geyser Basin, is the world's tallest currently-active geyser. Steamboat Geyser has two vents, a northern and a southern, approximately 20 feet (6.1 m) apart. The north vent is responsible for the tallest water columns; the south vent's water columns are shorter.[3]

Prior to 1904, Waimangu Geyser, in New Zealand, had some taller eruptions capable of reaching 1,600 feet (490 m), but in 1904, a landslide changed the local water table, and since then, Waimangu has not erupted.[4] Excelsior Geyser in Yellowstone's Midway Geyser Basin, and Semi-Centennial Geyser just north of Roaring Mountain on the Grand Loop Road were reported to be as tall as Steamboat, both with eruptions reaching 300 ft (91 m).[5] However, Excelsior has not erupted since 1985, and now functions as a hot spring, and Semi-Centennial's one eruption of this height was reported in 1922 and has been dormant since.

Steamboat's major eruptions generally last from 3 to 40 minutes (a couple of durations surpassing an hour were observed during the 2018 active phase[6]), and are followed by powerful jets of steam. During these eruptions, water may be thrown more than 300 feet (91 m) into the air.[7] Steamboat does not erupt on a predictable schedule, with recorded intervals between major eruptions ranging from three days to fifty years. The geyser was dormant from 1911 to 1961. In 2018, the geyser began a prolonged period of frequent activity lasting through at least 2021, with more than 40 eruptions recorded annually in both 2019 and 2020.

Minor eruptions of 10 to 15 feet (3.0 to 4.6 m) are much more frequent.

After an eruption, the geyser often vents large amounts of steam for up to 48 hours.[8] Sometimes during this part of an eruption, water may return to Steamboat, causing it to jet water once again, though to lesser heights.[6] Cistern Spring, located nearby, will drain completely following a major eruption of the geyser; the spring refills within a few days.

Recent eruptions and active phase of 2018-2021

The most recent eruption of Steamboat Geyser occurred on January 2, 2021 at approximately 1700 MST. In 2019 the 48th eruption for the year occurred on December 26th and this set a new annual number for eruptions.[9] This was the 127th eruption since it re-activated in early-2018.[10]

Many years may pass between eruptions, but in some years multiple eruptions have occurred. In 1964, twenty-nine eruptions were reported.[11] Eruptions from 1990 to 2018:

  • June 4, 1990
  • October 2, 1991 - (1 year 120 days)
  • May 2, 2000 - (8 years 213 days)
  • April 26, 2002 - (1 year 359 days)
  • September 13, 2002 - (140 days)
  • March 26, 2003 - (194 days)
  • April 27, 2003 - (32 days)
  • October 22, 2003 - (178 days)
  • May 23, 2005 - (1 year 213 days)
  • July 31, 2013 - (8 years 212 days)[11]
  • September 3, 2014 - (1 year 34 days)

Active phase since 2018

Steamboat Geyser, major eruption, August 4, 2018

In 2018, Steamboat Geyser entered a much more active period with 127 eruptions recorded between March 15, 2018 and January 2, 2021. [12][6][13] Thirty-two eruptions occurred in 2018, 48 occurred in 2019 and another 48 occurred in 2020. This broke 1964's record of 29 eruptions within a calendar year.[14] The 2018 record was broken on August 27, 2019 with the 33rd major eruption of the year.[15]

  • Minor eruptions on April 27, 2018
  • Major eruption on May 23, 2005
    Major eruption on May 23, 2005
  • Major eruption on May 23, 2005
    Major eruption on May 23, 2005
  • Steam venting on May 24, 2005
    Steam venting on May 24, 2005
  • Minor eruption June 22, 2008
    Minor eruption June 22, 2008

Notes

  1. ^ USGS' Steamboat counter lists this eruption as 3:23 AM, though in-basin report and seismic signal indicate 4:23 AM as start time.[17][18] This has since been corrected to 4:23 AM.
