    Let’s start with what happened on Saturday. An eruption of Ear Spring sent “plumes of water up to 30 feet in the air”, and it was being reported that “debris and rocks flew into the sky”

    On Saturday, Ear Spring erupted plumes of water up to 30 feet in the air, endangering visitors as debris and rocks flew into the sky.

    The last known eruption on that scale occurred in 1957, though several smaller eruptions were observed in 2004.

    Ear Spring is one of the hottest pools in Yellowstone National Park and contains water above the boiling point up to 200 degrees.

    If you are not familiar with this particular hot spring at Yellowstone, you can find the basics on Wikipedia right here. When a supervolcano that could ultimately kill billions of us starts flinging “debris and rocks” into the sky, that should have made front page headlines all over the planet, but it didn’t.

    This was the very first time since 2004 that Ear Spring has erupted, and it was only the 4th eruption in the last 60 years.

    But that wasn’t the end of the activity at Yellowstone.

    On Monday, Steamboat Geyser erupted “for an hour and fifteen minutes”

    Steamboat Geyser in Yellowstone National Park erupted on Monday for an hour and fifteen minutes. The spectacular stream of water and steam can reach heights of 300 feet, making it the tallest of any active geyser in the world. The most recent eruption was the geyser’s nineteenth in 2018, making this Steamboat’s most active calendar year since 1982, and exciting visitors and scientists alike.

    Mount Anak Krakatau in Lampung, Indonesia, erupted 44 times between Friday night and Saturday afternoon, according to the Meteorology, Climatology, and Geophysics Agency (BMKG).

    Dramatic images from the volcano, which lies in the Sunda Strait between Java and Sumatra, showed as billowing thick, black smoke spewed some 600 meters from the crater.

    Bright red, molten lava gushed from the volcano, spurting massive lava bombs which local media report are as big as trucks.

    Shocking footage showed the enormous fireballs bursting from the volcano overnight, sending lava cascading down the mountain’s slopes.

    Thunder sounds and weak tremors also occurred as the volcano blew.

    According to the Mount Anak Krakatau’s Observation Post, Volcanology Center and Geological Disaster Mitigation (PVMBG), the mount activity was accompanied by firelights and incandescent flow to the south.

    The volcano has been active sine June but had not caused any disruption - until now.

    Mount Anak Krakatau remains at alert level two and no people or tourists are allowed to go near the crater within 2 kilometers.
