Friday marks two months since a deadly earthquake struck Ishikawa Prefecture in central Japan. The disaster has put a spotlight on disinformation.

NHK has found that on the day of the earthquake and the following day, there were at least 23 social media posts which were viewed more than 10,000 times each.

They included specific addresses and calls for help, and some contained disinformation.

One post read, "My husband's legs are trapped and he can't get out. Emergency calls won't go through." The information in this post was confirmed to be fake.

NHK spoke to Kido Masahiko, the resident of the address listed in the post. He says he was at a colleague's home at the time of the disaster.

Kido says the quake damaged pillars in his home, but his family members who happened to be there were not hurt.

Three days later, the same account posted: "My husband has died." The posts were viewed about 72 million times.

Kido described the disinformation as "a nuisance." He said, "As a survivor of the disaster, I hope things like this never happen again."

There were also cases in which emergency responders were dispatched to a location based on false information contained in a post.

Someone called for help after noticing a post claiming that a person was buried under rubble. The post included an address in Kaga.

A team of emergency workers immediately headed to the site after receiving the call. But they found no evidence of any emergency situation at the listed address, where a storage facility was located. A fire department official in Kaga City warned that dispatching rescuers based on a false alert could prevent them from reaching those who are in genuine need of assistance.

A company in Japan that fact-checks social media posts has set up a team of experts that relays information to Ishikawa Prefecture officials.

The experts verify the address mentioned in a post by cross-referencing it with a map. They also check the account profile and past posts to see if the individual was actually at the site.

Experts say social media companies need to consider introducing a system to identify false information.
