More than 40,000 people had initially fled their homes, with many of those closest to the epicentre spending the night outside. Some are now returning to their homes despite the frequent aftershocks.More than 40,000 people had initially fled their homes, with many of those closest to the epicentre spending the night outside.

This quake was much more frightening and destructive than the initial magnitude figure of 6.4 might suggest.
Magnitude (energy released) is different from the intensity of shaking you actually feel. Because of that Japan has its own seismic scale, which measures the intensity of the shaking.
On this scale the Thursday night quake in Kumamoto measured 7 - the highest level. By this measure the shaking last night was as severe as that unleashed by the huge 9.0 quake that struck Japan in March 2011.
The fact that the damage was limited, and death toll so low, is testament to Japan's building regulations.
In 1981, following a large quake in northern Japan, tough new rules were brought in that stated all buildings should be able to withstand a magnitude 7.0 earthquake (Richter scale) with only minor damage.
If you look at the TV pictures from Kumamoto you can see most of the buildings that collapsed are older wooden houses, with heavy tiled roofs. In Kumamoto city itself modern high-rise buildings appear to have survived without any significant damage.
By Friday afternoon, more than 130 aftershocks had hit the area, which is where Japan's only online nuclear reactor is located, according to public broadcaster NHK.By Friday afternoon, more than 130 aftershocks had hit the area, which is where Japan's only online nuclear reactor is located, according to public broadcaster NHK.

The quake struck at a depth of 10km (six miles) and was followed by aftershocks measuring 5.7 about 40 minutes later and 6.4 just after midnight local time.The quake struck at a depth of 10km (six miles) and was followed by aftershocks measuring 5.7 about 40 minutes later and 6.4 just after midnight local time.
In one place, the quake was a seven - the highest level - on the Japanese earthquake intensity scale, which measures shaking at a location, rather than energy released.
"The shaking was so violent I couldn't stand still," Hironobu Kosaki, a local police official, told the Associated Press news agency."The shaking was so violent I couldn't stand still," Hironobu Kosaki, a local police official, told the Associated Press news agency.
