Compare Quake Data

Data for the same earthquake as reported by different agencies

The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.

Mag	Depth	Time GMT	Epicenter	Agency

Notes:
(*) A depth given as 10 km often means that the the depth of the quake could not determined with sufficient accuracy.
