Which animals know earthquake is coming?

Can earthquakes be predicted Yes or no?

No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.

Are there warning signs before an earthquake?
