Taiwan earthquake latest news: Dozens stuck in tunnels after biggest quake in 25 years - BBC News Taiwan earthquake latest news: Dozens stuck in tunnels after biggest quake in 25 years - BBC News

Some of you may have noticed difference in reporting of the exact power the initial earthquake off Taiwan's east coast, which are measured out of 10 on what are known as seismic magnitude scales.
Antoine Rousseaux, witnessed the first waves of the earthquake in the centre of Taipei this morning. This discrepancy is because there are differing methods of calculating an earthquake's power and three different figures for this particular incident have been given by major global agencies.
He was at work on the 9th floor of an office building when it "started to shake really, really hard." The BBC is reporting it as reaching a magnitude of 7.4, which is the calculation given by the United States Geological Survey.
"It’s not my first earthquake in Taiwan but I’ve never had it done that hard, and then I heard things falling down so I didn’t know what to do, I was like, 'should I run down the stairs?' However, Taiwanese authorities say it was a 7.2 magnitude quake, while Japan's method of calculating intensity came out at 7.7.
"And then I decided to just go under the table and sit down under the table but the Taiwanese were just standing up and we could see things falling down, it was really confusing.” Anything above 7 is considered a major earthquake.
“We are still in a bit of a shocked state because when it happened it was a really strong one, so even the Taiwanese were really scared... I could see they were not used to one with this strength." One thing to note is these measures are often incorrectly described as being on the "Richter Scale" - an earlier method of describing the size of earthquakes that has since largely been updated and replaced by scientists.
He says he and his colleagues then continued to experience aftershocks every 30 minutes.
