MYSTERY surrounds the cause of earth tremors on the Sunshine Coast that were reported across social media sites.
Bli Bli and Wurtulla residents have revealed they felt a "rumble" about 3.30pm yesterday that may have been preceded by a "big bang".
Some have pinpointed controlled explosions at a nearby construction site as the cause, but that has yet to be confirmed.
"(The) whole house shook for a good few seconds," Robert Alexander reported..
Wurtulla resident Andrew Lowe said he felt two "rumbles"
"I felt very small ones."
Geoscience Australia Earthquakes has not registered a quake on the Sunshine Coast at that time.
The last earthquake to be felt on the Sunshine Coast was on August 17 when a 5.8 magnitude quake shook parts of Queensland when it occurred 70km offshore from Bowen.
A construction company working in the Bli Bli area has been contacted for comment.
