Japanese city covered in mysterious carpet of foam after earthquakes
Baffled residents discovered the foam and tweeted pictures of the substance
A BIZARRE carpet of foamy bubbles has covered the streets of a Japanese city after an earthquake shook the town on Saturday morning.
Bemused residents discovered the foam in the busy central district of Tenjin, Fukuoka.
Twitter users posted pictures of the foam which have since gone viral.
Some have speculated that the earthquake might have caused an underground pipe to burst, covering the city's streets with the substance.
However, there has still been no official explanation.
Fukuoka is 90km away from Kumamoto, where the strongest tremors were felt.
Residents reported strong shaking but little damage from the two quakes, which took place on Friday and Saturday.
The 7.3 magnitude earthquake is thought to have killed at least 42 people so far and has left 410,000 homes without water and 200,000 with no power.
Crowds of people are queuing for food and water at emergency aid centres, while supermarket shelves have been left empty after a wave of panic buying.
A further 250,000 people have also been told to leave their homes amid fears of tremors and more quakes.
