Earthquake Prediction. Two questions to Seismologist pertaing to Plate tectonics

 hi 

 Here are two simple questions which need to be answered  based on existing plate tectonic theorry

1) Why there are big quakes at locations other than plate boundries

2) Why there are dozens of small quakes (less than 4 on R Scale) daily?

 This is an open invitation to all those who thinks that ,one and only reason for quakes is plate frictions and there is no other reason what so ever
