The cities of East Sacunda and West Sacunda are in an earthquake-prone area. Since 1985 both cities have had stringent building codes requiring all new buildings to have specific features designed to prevent damage in an earthquake. Buildings built before 1985 are exempt from the codes, but many building owners have modified their buildings to make them conform to the 1985 codes. Last year a major earthquake hit the area, and many people lost their homes. The number of people who were left homeless was much higher in East Sacunda than in West Sacunda, however, so we can conclude that building owners in East Sacunda were less likely to modify their buildings so as to bring them up to the 1985 code standards.
