A strong earthquake shook the Taiwanese capital, Taipei, early Friday. There were no immediate reports of injuries or casualties.
Quakes frequently rattle Taiwan, but most are minor and cause little or no damage.
However, a 7.6-magnitude earthquake in central Taiwan in September 1999 killed more than 2,300 people, and in December 2006 a 6.7-magnitude offshore tremor south of the city of Kaohsiung severed two undersea cables and disrupted telephone and Internet service to millions of users throughout Asia.
Russian President Vladimir Putin, in his speech dedicated to the Day of the Russian Navy, recalled the threats that Russia is currently facing from a number of countries.
