A new study suggests that an underwater fault line along the US West Coast, known as the Cascadia Subduction Zone, could trigger a megaquake more devastating than California's 'Big One.' Scientists have mapped the fault line in detail and concluded it has the potential to cause a nine-plus magnitude quake, generating tsunamis and causing widespread destruction.
Key Points
Cascadia Subduction Zone could unleash a nine-plus magnitude quake, more devastating than California's 'Big One'
Fault splits into four segments, increasing the potential for severe earthquakes
Similar fault zone off the coast of Japan erupted in 2011, causing significant devastation
Emergency response models need updating based on new data
States like Oregon and Washington not adequately prepared for potential disaster
Pros
Detailed mapping of the Cascadia Subduction Zone provides valuable insight into potential seismic risks
Findings could help states in the impact zone prepare for emergency response and evacuation
Cons
Potential for a catastrophic earthquake with significant loss of life and property damage
