This seismogram is from the Cornudas Mountains seismic station in western Texas, USA. The noise is from a West Texas magnitude 5.4 earthquake that hit at 8:47 PM, local time, on 3 May 2025. The epicenter was between Cave Well Peak and Table Top, west of the Rustler Hills in western Texas. The hypocenter was between 7 and 8 kilometers deep.
This general region, which is northwest of the town of Pecos, Texas, experiences many small earthquakes. The seismicity is not natural - these "induced earthquakes" are a consequence of waste fluid injection activity. A magnitude 5.4 quake is unusually powerful for the area. A 5.3 quake occurred in the same area in November 2022 and a 5.4 quake occurred in November 2023.

An earthquake is a natural shaking or vibrating of the Earth caused by sudden fault movement and a rapid release of energy. Earthquake activity is called "seismicity". The study of earthquakes is called "seismology". The actual underground location of an earthquake is the hypocenter, or focus. The site at the Earth's surface, directly above the hypocenter, is the epicenter. Minor earthquakes may occur before a major event - such small quakes are called foreshocks. Minor to major quakes after a major event are aftershocks.
Most earthquakes occur at or near tectonic plate boundaries, such as subduction zones, mid-ocean ridges, collision zones, and transform plate boundaries. They also occur at hotspots - large subsurface mantle plumes (Examples: Hawaii, Yellowstone, Iceland, Afar).
Earthquakes generate four types of shock waves: P-waves, S-waves, Love waves, and Rayleigh waves. P-waves and S-waves are body waves - they travel through solid rocks. Love waves and Rayleigh waves travel only at the surface - they are surface waves. P-waves are push-pull waves that travel quickly and cause little damage. S-waves are up-and-down waves (like flicking a rope) that travel slowly and cause significant damage. Love waves are side-to-side surface waves, like a slithering snake. Rayleigh waves are rotational surface waves, somewhat like ripples from tossing a pebble into a pond.
Earthquakes are associated with many specific hazards, such as ground shaking, ground rupturing, subsidence (sinking), uplift (rising), tsunamis, landslides, fires, and liquefaction.
Some famous major earthquakes in history include: Shensi, China in 1556; Lisbon, Portugal in 1755; New Madrid, Missouri in 1811-1812; San Francisco, California in 1906; Anchorage, Alaska in 1964; and Loma Prieta, California in 1989.
This map shows 279 earthquakes in part of the Permian Basin of West Texas, USA. They occurred over one month from 3 April to 3 May 2025. Magnitudes were mostly in the 1s, 2s, and 3s. The large orange dot at left is a magnitude 5.4 quake on 3 May. This seismicity is not natural - these "induced earthquakes" are a consequence of waste fluid injection activity. A magnitude 5.4 quake is unusually powerful for the area.
