– A new map released by the California Department of Public Health shows that 1 in three residents in the state live in a “severe earthquake risk area” where a magnitude-6.7 earthquake could cause widespread damage and death.
The map shows the average number of days per year when residents in a given ZIP code are in this type of earthquake riskzone.
The number of people living in the zone rose in 2017 from 9.7 days per 100,000 residents to 9.9 days per 1,000 people, according to the map.
In 2017, the median number of residents in these quake risk zones was 4.4, according the map, which was produced by the USGS and the California Geological Survey.
The state has a population of 5.4 million people, making it the third most populous state in the country.
It was estimated in 2015 that California has the largest earthquake risk in the nation.
