Japan Today reported that authorities in the village of Minamiaso and Mashiki town that were hit hard during the April quakes have issued evacuation orders to over 38,000 residents in the two areas. Southern Japan was hit by two major earthquakes of magnitude 6.5 and 7.3 between 14 and 16 April that left scored dead.

The quakes followed by aftershocks loosened the soil causing mudslides in the rain-hit areas. A fresh aftershock was also felt on Wednesday morning, Reuters reported.
