Here is another pretty big earthquake. Those on the islands of Adak and Atka probably got shook pretty strongly.
The moment tensor shows a compressional earthquake and this is consistent with this setting on a subduction zone. If this EQ lies on the subduction zone fault, then it shows the dip of the subduction zone is about 22 degrees +-.
Here is a cool animation for the earthquake from NOAA PMEL. This earthquake is highly unlikely to generate a tsunami, but these scientists do this for all earthquakes that could generate a tsunami.
