Smaller quakes, past 7 days

Under magnitude 2.5, which few people feel.

Largest on record in Maine

The 25 largest in the USGS catalog since 1900, of magnitude 3 and up. Older magnitudes are estimates from historical accounts and early instruments.

What this means

Magnitude measures the energy a quake releases: each step up is about 32 times more energy, so an M6 releases about a thousand times the energy of an M4. Intensity measures the shaking at one place, which depends on the distance, the depth and the ground. One quake has one magnitude and many intensities.

The Modified Mercalli intensity scale
IntensityShakingWhat people notice
INot feltRecorded by instruments only.
II to IIIWeakFelt by a few people at rest, mostly on upper floors; hanging objects may swing.
IVLightFelt indoors by many. Dishes, windows and doors rattle; like a heavy truck passing.
VModerateFelt by nearly everyone; sleepers wake. Some dishes break and unstable objects tip over.
VIStrongFelt by all; heavy furniture moves, plaster cracks. Damage is slight.
VIIVery strongDamage slight to moderate in ordinary buildings, considerable in poorly built ones.
VIIISevereConsiderable damage in ordinary buildings, with partial collapse; chimneys and walls fall.
IX and upViolent to extremeHeavy damage even in well-designed buildings; many shifted off foundations.

Did I just feel an earthquake?

A quake appears in these lists within minutes: a few for the US, up to twenty for a quake abroad. Search your town above, or open your state. If it was a quake, tell the USGS through its Did You Feel It? form. If shaking starts: drop, cover and hold on; stay indoors until it stops; near the coast, move to high ground after strong or long shaking without waiting for a warning.

By state

Every state, with the quakes of magnitude 2.5 or more located there in the past 30 days. Each state page adds the smaller quakes of the past week and its largest on record.
