Beach Balls Explained: Strike-Slip Faults
/@AKearthquake During coverage of the M7.9, you might have seen a cryptic, beach ball-looking symbol used as a way of showing that it was a strike-slip earthquake, unlikely to generate a major tsunami. Here's Helena Buurman's visual explainer. You might need to download and view on a desktop.
Understanding the Mystery of Earthquake Beach Balls
/Written by Dr. Gemma Smith, Geologist & Geophysicist
Dr. Gemma Smith is a young Research Assistant in Earth Sciences at the University of Southampton. Her PhD did focus on the geophysical investigation of the Makran subduction zone, in order to further understand its deformation and seismogenic potential. The Makran Subduction Zone experienced a tsunamigenic Mw 8.1 earthquake in 1945 and recent, smaller earthquakes also suggest seismicity on the mega-thrust, however its historical record is limited and hazard potential enigmatic
Effect of fault types on stress regime
/Can someone explain how different fault types (dip-slip, strike-slip, etc) tend to affect the stress regime (orientation and magnitude) across them? Is there a specific way how these faults affect the stress regime, individually, or there is no definitive correlation between the fault type and stress variation?
