A baffling carpet of foam has covered the streets of a town in Japan following an earthquake which shook the area in the early hours of Saturday morning.
Residents in Fukuoka took photos of the strange bubbles which appeared after a 7.3-magnitude quake hit the Kumamoto region, around 90km away.

Another 6.5-magnitude earthquake struck the area on Thursday night.
According to Mashable, local reports suggest an underground pipe burst could have caused the foam but that there was little information available.
At least 41 people were killed in the Kumamoto quakes.
