‘Artificial earthquake’ conspiracy theory sweeps Japan after Kumamoto disaster

Claims that the recent magnitude 7.1 earthquake that struck southwestern Japan was man-made have been spreading online, with experts dismissing the theory as unrealistic in technological, financial and practical terms.On July 28, the day the deadly earthquake hit Kumamoto prefecture, a user on social media who has previously shared false claims about earthquakes wrote that the “seismic wave is of an explosion, not a quake” in a post that has had around 3 million views as of Wednesday.Searches of posts mentioning an “earthquake" class="entity-link entity-topic" data-entity-id="179334" data-entity-type="topic">artificial earthquake” in Japanese using an analysis tool from US firm Meltwater showed hundreds of references tracked in the days before the quake. They surged to about 10,000 on the day of the disaster and around 38,000 on the following day.
