USGS said, “The recorded ground motions from this event are more typical of an explosion than a naturally occurring earthquake. The Navy has conducted Full Ship Shock Trials in this region in the past."
Action News Jax has reached out to the Navy for more information on Tuesday’s “experimental explosion.”
The USGS is asking people who felt the tremor to report it by filling out this form on their website.
