After this week's spike in destructive Japanese earthquakes, which in addition to the two strongest tremors since 2011 has also unleashed several hundred smaller aftershocks and led to over 40 deaths, thousands injured, landslides, collapsed buildings and extensive damage, the most surprising aftereffect appeared yesterday on the streets of the southern Japanese city of Fukuoka which became blanketed in "mysterious foam" leaving residents baffled by the phenomenon which the authorities, busy with the disaster’s aftermath, found no time to explain.

The froth appeared shortly after disastrous tremors from a 7.3 magnitude quake shook the city of Fukuoka on Friday. Twitter users posted photos of the snow-like foam sheet and wondered what caused it.
The unexplained phenomenon affected the downtown Tenjin and Imaizumi areas of Fukuoka, according to reports.

Some speculated that it may be the result of a burst underground pipe caused by the earthquake. Others suggested it could have been common firefighting foam, although no fire trucks could be seen anywhere in the photos.

There has been no official explanation for the foam as of yet. Speculation that this is simply a logical consequence of the BOJ owning over half of Japan's ETFs and on pace to also own half of Japan's government bonds have so far been unconfirmed.
