Retrospective plans, otherwise known as retros, are claim sensitive workers compensation rating programs specifically designed and used when an employer is of the size required to justify its use.

Because of the size of these plates, earthquake waves carry huge amounts of energy. In this lesson, we discussed four types of seismic waves: P-waves, S-waves, Rayleigh waves and Love waves. The first two are body waves, the latter two are surface waves. Love waves cause the most damage and P-waves the least. Thanks to our study of seismic waves, we have a better idea of what to expect when an earthquake hits. Through this knowledge and better preparation, we can save both property and human lives.
