A powerful 7.3 magnitude earthquake struck southern Japan early on Saturday, killing at least 19 people, injuring hundreds more and trapping people in collapsed buildings, barely a day after a quake killed 10 people in the same region.
Rescuers dug through the rubble of collapsed buildings and mud and debris on Saturday to try and reach those trapped, but continued aftershocks hindered rescue efforts and fuelled fears of more powerful quakes. "We have already seen of several of the mid to upper 5 plus magnitude range, and over the next several days and weeks, we would not be surprised to see more earthquakes of this size," said John Bellini, a geophysicist with the US Geological Survey (USGS).
