text: There can be some tremors that precede a quake.  This is called a foreshock sequence.  Unfortunately, it is impossible to determine a foreshock sequence until after the quake occurs.  There may also be surface disruption with land features being slightly twisted or misaligned.  In some rare instances, natural springs have stopped or started before a quake happened although this usually happens as a result of a quake.\n\nIn general, there is very little that we are aware of yet in terms of warning signs of a pending quake.
