Record Wildfire in Texas (Image of the Week)
The Smokehouse Creek Fire started about 1 mile north of Stinnett, Texas on February 26th, 2024. Three days later, the fire had consumed over 1 million acres. With a total area of 1,654 square miles, it became the largest fire on record in Texas. That's larger than New York's Long Island.
A series of false color images reveal the land cover before, during, and after the fire.
February 24th, 2 days before the fire.

Swimming Pools at Yellowstone? (Yellowstone Monthly Update - June 2024)
Просмотров 25 тыс.14 дней назад
Up until the 1950s, visitors to the Old Faithful area could take dip. Not at a geyser, but in a real swimming pool. The full story is in this month’s video update.

      Great suggestion! We created and uploaded an animated GIF showing patterns of seismicity by year during 2017-2023. You can find that at www.usgs.gov/media/images/animation-annual-yellowstone-seismicity-2017-2023. The number of quakes fluctuates, mostly due to the occurrence of large swarms (which show up really well on the maps as tight clusters of numerous small earthquakes). Swarms are mostly caused by groundwater interacting with preexisting faults (which are plentiful throughout the region). The numbers of earthquakes each year are 2017 - 3,427 2018 - 2,007 2019 - 1,218 2020 - 1,722 2021 - 2,773 2022 - 2,429 2023 - 1,623 We'll see about doing a "caldera chronicles" article on this topic (that's our weekly article about some aspect of Yellowstone geology/activity, accessible at www.usgs.gov/volcanoes/yellowstone/caldera-chronicles and USGSVolcanoes social media channels).

      Yellowstone's most recent caldera-forming eruption was 631,000 years ago. There was no ice covering the area at the time. Lava flow eruptions have happened when the region was glaciated, however -- about 130,000-150,000 years ago. Some of the lava flows that erupted during this time (www.usgs.gov/observatories/yvo/news/lotta-lava-new-insights-timing-yellowstones-most-recent-rhyolite-eruptions) show signs of having interacted with ice, and there is evidence that glacial lakes might have been present in the region at various times.

    2:25, you say mt. St. Helens mountain didn't even form until 4000 years ago. Is that true or a mistake?

      Not a mistake! There has been volcanism in the area for 275,000 years. But the edifice that we know today didn't really start growing until about 4000 years ago.
