The report claimed that Chen had admitted to illegally entering the Guangxi province's seismology website at the end of May in a bid to show off his technical skills.
After hacking into the site, it is alleged that the 19 year-old altered text on the home page to warn of a "huge earthquake of magnitude 9 or more".
The hack came just weeks after devastating earthquakes in the Sichuan province on 12 May which killed around 70,000 people.
Police arrested Chen on 4 June in Taicang city, after he hacked into the same site and deleted data on 1 June and 2 June.
According to the report, the teenager had been held for five days in March for other hacking offences.
No details surrounding a trial date or possible sentence were given.
