What are the most dangerous volcanoes in the US?

Geology

The May 18, 1980 eruption of Mount St. Helens (Washington) was the most destructive in the history of the United States. Novarupta (Katmai) Volcano in Alaska erupted considerably more material in 1912, but owing to the isolation and sparse population of the region, there were no human deaths and little property damage.

      • What volcano just erupted in 2021?

      Stunning Etna eruption

      Mount Etna is the most active volcano in Europe, so it’s not surprising that it erupted again in 2021. But when it blew its top in February, photographers caught some stunning images of lava spewing from the summit.

      Which state in the US has at least 1 volcano?

      4 Washington 7

      Are there any volcanoes in NY?

      No. The geologic forces that generated volcanoes in the eastern United States millions of years ago no longer exist. Through plate tectonics, the eastern U.S. has been isolated from the global tectonic features (tectonic plate boundaries and hot spots in the mantle), that cause volcanic activity.

      What will happen if Yellowstone erupts?

      The enormous amount of volcanic material in the atmosphere would subsequently rain down toxic ash; across the entire US, but principally in the Northwest. The ash would also kill plants, animals, crush buildings with its weight, block freeways, and ruin the country’s farmland for a generation.

      How hot is lava?

      When lava first breaks through Earth’s surface, it is an extremely hot liquid. On average, fresh lava can be between 1,300° F and 2,200° F (700° and 1,200° C)! Depending on its exact temperature, fresh lava usually glows either orange/red (cooler) or white (hotter).

      Can you freeze lava?

      Magma and lava solidify in much the same way that water freezes. When magma or lava cools down enough, it solidi- fies, or “freezes,” to form igneous rock. One difference between water freezing and magma freezing is that water freezes at 0°C and magma and lava freeze at between 700°C and 1,250°C.



      Can lava melt diamonds?

      To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.

      Is lava hotter than the sun?

      Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can’t hold a candle to the sun! At its surface (called the “photosphere”), the sun’s temperature is a whopping 10,000° F! That’s about five times hotter than the hottest lava on Earth.

      How hot is the moon?

      The moon’s temperature can reach a boiling 250° Fahrenheit (120° Celsius or 400 Kelvin) during lunar daytime at the moon’s equator, according to NASA.

      What’s the hottest thing in the universe?

      The hottest thing in the Universe: Supernova

      The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun’s core.



      How cold is space?

      Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

      Why is space dark?

      Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black. —What color is the sunset on other planets?

      How much closer to the sun before we burn?

      You can get surprisingly close. The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up.

      What does space smell like?

      A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [like] … sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.



      Can you fart in space?

      Surprisingly, that isn’t the biggest problem associated with farting in space. Though you’re definitely more likely to worsen a small fire when you fart, it won’t always injure or kill you. The worst part about farting in space is the lack of airflow. Let’s take a step back and remember how farting on Earth works.

      Is there any human lost in space?

      Originally Answered: Has anyone ever been lost in space? No. People have died training for space, trying to get into space, and returning from space but nobody has really died in space. The one incident that technically happened in space was Soyuz 11, in which a vent valve opened and caused depressurization.

      Why can’t you see the sun in space?

      In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

      How do female astronauts deal with periods in space?

      A combined oral contraceptive, or the pill, used continuously (without taking a week off to induce menstrual flow) is currently the best and safest choice for astronauts who prefer not to menstruate during missions, says Varsha Jain, a gynecologist and visiting professor at King’s College London.

      Why is the sun so hot but it’s cold in space?

      The reason is obvious: sunlight contains energy, and in near-Earth space, there is no atmosphere to filter that energy, so it’s even more intense than it is down here. Now, on Earth, if you put something out in the sun, it warms up.
