The Seattle Fault is the structural boundary where 50–60 million years old (early Tertiary) basalt of the Crescent Formation on the south has been uplifted – the Seattle Uplift – and is tipping into the Seattle Basin, where the Tertiary bedrock is buried under at least 7 km (4.3 miles) of relatively softer, lighter sedimentary strata of ...
One study of seismic vulnerability of bridges in the Seattle – Tacoma area [4] estimated that an M 7 earthquake on the Seattle or Tacoma faults would cause nearly as much damage as a M 9 subduction earthquake. Because the Seattle and Tacoma faults run directly under the biggest concentration of population and development in the region, more ...
Damaging earthquakes are well known in the Pacific Northwest, including several larger than magnitude 7, most notably the M9 1700 Cascadia earthquake and the M7.0–7.3 earthquake in about 900AD on the Seattle Fault. The M6.5 1965 Puget Sound earthquake shook the Seattle, Washington, area, causing substantial damage and seven deaths. This event ...
Taylor Swift fans are in their record-breaking era.. After two nights of earth-shaking dancing at Swift’s Seattle “Eras” tour concert at Lumen Field, enthusiastic Swifties caused seismic ...
The quake, which had a center near Ferrelview and the Kansas City International Airport, was reported around 1:45 p.m. March 15. Magnitude 3.5 earthquake near KCI was caused by mine collapse: USGS ...
An earthquake is what happens when the seismic energy from plates slipping past each other rattles the planet's surface. Those seismic waves are like ripples on a pond, the USGS said.
