Guam security officials are meeting with leaders as the territory tries to prepare in the face of threats from North Korea.
The North has threatened to attack bases on Guam if the United States launches a strike on it.
A Joint Information Centre has been activated this week, including Guam Homeland Security, fire and police services, health services, and the Governor's office and military.
Guam Homeland Security's Dee Cruz says people are continuing to go about their normal lives.
"They're still going to work, they're still sending their kids to school. We just want to make sure that those individuals that don't have social media, that they're reading a lot of stuff in newspapers, they're watching the news and it's being repeated. So there's a little bit of fear, but they're really assured when they do call our office and we give them they answers that they need."
Dee Cruz says the most important things for people to do are to keep informed and prepare an emergency kit.
Local media is reporting that Governor Eddie Calvo has cancelled a trip to China in order to stay on the island.
