The Active Faults of Eurasia Database (AFEAD)
AFEAD includes more than 40 000 fault segments that were identified as active with varying degrees of confidence. The database includes data on morphology, kinematics and seismicity, reproducing data from cited studies. References are provided for each entry.
The initial collection of the data is supplemented with uniform attributes of fault slip type, slip rate and a level of confidence in recent activity. Those attributes are maintained by the database owners, but were estimated, not evidenced.
To users of the database
The use of the Active Faults of Eurasia Database for any purpose implies the following:
1. The database is a COMPILATION of published data of many researchers. Reference to the database as a data source is erratic – one must refer directly to the initial sources cited in the database for specific objects.
2. The database provides an index of CONFIDENCE for each entry, from high to extremely low. Each object of the database may be interpreted as an active fault only considering its confidence value. Note especially that CONF = ”C” indicates weak evidence for the activity of the fault, whereas CONF = ”D” may refer to absent evidence of activity.
