Did we just have an earthquake near me?
Check the list at the top of this page. It reads the U.S. Geological Survey's live feed every few minutes. Automatic locations for most US quakes appear within minutes, and small or remote ones can take longer. If you felt shaking that isn't listed yet, wait a few minutes and refresh, or report it to the USGS "Did You Feel It?" survey.
The last 12 months
39 earthquakes of magnitude 2.5 or more in Wyoming in the last 12 months. The largest was M4.7, 40 km S of Evanston, Wyoming, on Jan 22. The busiest week began Jul 14, with 4 quakes.

Why does Wyoming get earthquakes?
Most of Wyoming's earthquakes happen in its northwest corner, in and around Yellowstone National Park. Beneath Yellowstone lies a large volcanic system, and the movement of hot water, gas and magma under the caldera produces about 1,500 to 2,500 small quakes a year, often in swarms of dozens to hundreds over a few days. Swarms like these are normal and are not, on their own, a sign of an eruption.
The largest quake inside the park in modern times was a magnitude 6.1 near Norris Junction in June 1975; just outside it, the M7.3 Hebgen Lake earthquake of 1959 struck across the line in Montana. The Teton Fault near Jackson can also produce large quakes, though none has in recorded history.

What magnitude earthquake can you feel?
People close to the epicentre often feel quakes from about magnitude 2.5 to 3, especially indoors on upper floors. Below that, most go unnoticed. How strong it feels depends on distance, depth and the ground under you, so a shallow M3 nearby can feel stronger than a deep M4 farther away.
How long do aftershocks last?
Aftershocks are most frequent in the first hours and days after a quake and then fade, though after a large one they can go on for months or even years. Most are smaller than the main shock, but a damaging one is possible. For significant US quakes, the USGS publishes an aftershock forecast with the chances for the coming days and weeks.
What should I do during an earthquake?
Drop, cover and hold on: get down on your hands and knees, cover your head and neck under a sturdy table, and hold on until the shaking stops. If you're in bed, stay there and protect your head with a pillow. Don't run outside during shaking, and keep away from windows. Doorways aren't safer in most modern homes. See Ready.gov and the Earthquake Country Alliance for more.
Can earthquakes be predicted?
No. Scientists can't predict the time, place and size of a particular earthquake. They can estimate the chance of a large quake in a region over decades, which is how building codes and insurance are set. On the West Coast, the ShakeAlert system can give seconds of warning once a quake has started, but that's detection, not prediction.

How this page works
The lists read the U.S. Geological Survey's real-time feeds: every quake of the past day and every quake of magnitude 2.5 or more of the past month, refreshed every few minutes. The 12-month history and the 50-year list come from the USGS earthquake catalogue (ComCat), read once a day and once a week. A quake counts here when the USGS names Wyoming as its place, offshore quakes included.
First magnitudes and locations are automatic and are often revised within hours; rows marked "auto" haven't been reviewed by a seismologist yet. Felt reports are the number of "Did You Feel It?" responses the USGS has so far. Times are local (America/Denver).
