Earthquakes near Houston

Reading the latest USGS reports for the ground near Houston…

Live sections load from the USGS feed. If the feed does not answer, this page says so — it never fills the gap with old numbers.

Recorded USGS earthquakes from the last 7 days, magnitude 2.5 and larger, within 250 km of Houston. The dashed pale circle is a true 250 km radius around Houston; amber rings are the recorded epicenters, sized by magnitude; small cream squares are the other towns, and the ringed cream marker is Houston. If the USGS feed does not answer, the coastline, ring, and marker still show — and no events are plotted.

Most felt near Houston — last 7 days, within 250 km

Recent near Houston — last 7 days, M1.0 and larger within 250 km, newest first

Every event links to its USGS event page, the authority for that earthquake. Distances are measured from Houston, not copied from the feed's place names.

The biggest on record near Houston — USGS catalog, as recorded

The five largest earthquakes recorded within 200 km of Houston since 1900, from USGS catalog pulls made November 8, 2026. Pre-instrumental magnitudes are estimates, and catalog completeness varies by era — the fine print is on the about page.

How often does the ground move here?

223 earthquakes of M4.0 or larger were recorded within 200 km in the last 10 years — one of the most active rates. Many of them are aftershocks of the November 30, 2018 M7.1 Anchorage earthquake, so the count overstates the lone-event rate. Since 1900 the catalog holds 1093 M4-or-larger events within the same radius.

Houston, Alaska sits in the Susitna lowland, where deep sedimentary soils can amplify shaking from the region's three regular sources: the offshore megathrust, the slab under Cook Inlet, and the Castle Mountain fault along the valley's north side.

Southcentral Alaska — why it shakes

Southcentral Alaska sits above the place where the Pacific Plate slides beneath North America — the Aleutian megathrust. That collision built the Alaska Range and produced the two largest earthquakes in recorded U.S. history. Most of the region's shaking comes in three flavors: megathrust earthquakes offshore in the Gulf of Alaska and Prince William Sound, earthquakes inside the sinking Pacific slab 30 to 150 km down (the kind felt as a long roll across the whole region), and shallow breaks on crustal faults like the Castle Mountain fault in the Matanuska Valley.

New to the numbers? What magnitude means explains the scale in plain words — including why a whole step is about 32 times the energy, and why what people feel is not the same as damage.
