No deaths, few injuries. The Edgecumbe earthquake has given rise to many informative studies. The 1987 Edgecumbe earthquake measured 6.5 on the moment magnitude scale and struck the Bay of Plenty region of New Zealand on 2 March. The 1987 Edgecumbe earthquake was by far the most expensive event during this period, resulting in $209 million in Earthquake Commission payouts, followed by the 1968 Inangahua earthquake, and landslide events during 2005. (From Dowrick and Rhoades, 1995) Figure 2: Probability of death in or beside URM and SSRC buildings as a function of MM intensity in New Zealand (SSRC = soft storey pre-code reinforced concrete).
