- In the case of a fault-related event, it refers to the orientation of the fault plane that slipped, and the slip vector and is also known as a fault-plane solution.
- Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms.
- The focal mechanism can be derived from observing the pattern of "first motions", whether the first arriving P waves break up or down.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Focal mechanism article was read about 9,500 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 56 and blocks with 40: each hit it takes is cut by 16 %.
