Guam authorities said North Korea's latest missile launch is a reminder for the territory to be prepared for any scenario.
A ballistic missile fired this morning is the first in more than two months.
Guam Homeland Security and Civil Defense issued a statement that said there was no immediate threat to the territory from the launch.
The Guam Homeland Security Advisor George Charfauros said the launch is a reminder to keep emergency plans updated.
"After two months of no missile activity out of North Korea, this morning's launch reminds us to keep emergency plans updated and be prepared for any scenario," he said.
The agency said the launch was detected out of Sain Ni, North Korea and traveled about 1,000km on a lofted trajectory before landing in the Sea of Japan, over 200km from the Japan coast.
Initial assessments state the reported missile was in the air for over 50 minutes.
Guam is about 3500 km from North Korea.
Pacific Daily News reports Guam's delegate to Washington, Madeleine Bordallo, said she's confident in the military's ability to keep Guam safe, but has urged a diplomatic solution to the tensions between the US and North Korea.
"It is unacceptable that North Korea continues to make advancements to its illicit nuclear and ballistic missile programs," she said in a news release.
"I hope the Trump Administration will work with the international community to peacefully resolve these threats."
