But the Seattle and Tacoma faults are probably the most serious earthquake threat to the populous Seattle–Tacoma area. A 2002 study of bridge vulnerability estimated that a magnitude 7 earthquake on the Seattle Fault would damage approximately 80 bridges in the Seattle–Tacoma area, [ 30 ] whereas a magnitude 9 subduction event would damage ...
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 ...
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 ...
The U.S. Geological Survey has determined that a magnitude 3.5 earthquake that jostled the Kansas City metro area last month was caused by a mine collapse.. The quake, which had an epicenter near ...
Scientists knew it wasn’t an earthquake, so they labeled the event a USO (unidentified seismic object) and began searching for a cause. The investigation (involving 68 scientists, 40 ...
In 2011, NBC Sports’ ProFootballTalk reported that retired Seattle Seahawks’ running back Marshawn Lynch’s touchdown against the New Orleans Saints also recorded a tremor on the seismometer ...
