North Korean leader Kim Jong Un has not directly threatened Hawaii, but missile test launches over Japan and increased tension between his country and the United States prompted Hawaii officials to address the issue of preparedness.

An HI-EMA fact sheet explains that, based on the estimated yield of North Korean missiles, there could be anywhere from 50,000 to 120,000 burn casualties and nearly 18,000 fatalities if an attack occurs.

After an attack, residents would have to stay sheltered in place until the HI-EMA has fully assessed the radiation and fallout, which could take a few hours or as long as 14 days, the agency says on its website.

State officials have been holding town halls to answer questions from residents.

Hawaii currently has an alert warning for natural threats like hurricanes and tsunamis. Both signals will be tested on the first business day of each month.
