Information from recent geophysical and geological investigations constrains the potential rupture-zone geometry and average repeat time of inter-plate thrust earthquakes. Based on this information, tsunami hazard maps have been prepared for coastal communities in the Pacific Northwest using sophisticated numerical models to simulate tsunami propagation and inundation.
In this study, sources of uncertainty in tsunami hazard calculations are described and a probabilistic hazard analysis for tsunamis, similar to probabilistic seismic hazard analysis (PSHA), is outlined.

Though probabilistic tsunami hazard analysis (PTHA) shares many similarities with PSHA, there are specific issues unique to tsunami hazards that need to be accounted for in the probability calculations.

M-Class Flare Launches From Region 1166
An M-class flare sets off from sunspot region 1166. Region 1169 also looks prone for M-class activity.
Six sunspot regions are coming along the farside of the Sun and should begin to rotate around the western limb in the in the next 72 hours.
Equation: Sunspots => Solar Flares (charged particles) => Magnetic Field Shift => Shifting Ocean and Jet Stream Currents => Extreme Weather and Human Disruption (mitch battros 1998)
Watch for continued extreme weather which includes earthquake and volcanic activity.
