Volunteers at the North American Aerospace Defense Command are monitoring Santa Claus as he makes his famous trip across the world as detailed in "'Twas the Night Before Christmas," Associated Press reports.

NORAD says it has tracked Santa's movement from Australia to Africa by using the heat from Ruldolph the Red Nosed Reindeer's nose.

The volunteers were answering phone calls and emails from children on Christmas Eve and posting updates on the fictional journey to social media and on NORAD's Santa website.

NORAD tracks Santa has already gained over 1.5 million likes on Facebook.

Technology and social media has become an important part of the 59-year-old program which has become a U.S. and Canadian military tradition over the years.

Now, the NORAD Tracks Santa has a control center at Peterson Air Force Base in Colorado Springs.

The tradition of tracking Santa down started in 1955, U.S. News reports. Sears Roebuck & Company printed the wrong phone number for children to call Santa and, instead, they were directed to a hotline for NORAD.

To keep up with the holiday spirits, the organization played along and answered the children's questions.

To spice it up this year, the Department of Defense joined the fun and announced that it created an "Anti-Grinch Firewall" to stop any foreign enemies from tracking down Santa and ruining Christmas.

The NORAD Santa Tracker can be found at NORADSanta.org or on the "NORAD Tracks Santa" app which is available on Apple, Windows Phone, iOS and Android.

Anxious children can also get updated on Twitter at @NORADSanta.

Google also has its technology that tracks Santa, Next Web reported.

Both trackers say Santa stopped in Russia first but each has two different cities listed. The Google Santa Tracker app is only available for Android, however.

The Santa Tracker for Google started in 2004 and has special features that tell you how long it takes for St. Nick to deliver a gift and shows short cartoon videos along the journey.
