Just over 24 hours after an earthquake rattled southern Japan, killing nine, a 7.0-magnitude quake struck the same region.
A tsunami warning was issued, but later lifted, after the earthquake struck 1 km (0.5 of a mile) from Kumamoto at 1:25 a.m. local time on Saturday (12:35 p.m. EDT Friday).
On Thursday night, a 6.2-magnitude quake rocked the same area, causing hundreds of injuries and widespread structural damage.
At least 45 aftershocks greater than magnitude-3.0 were recorded in Japan after the initial quake, according to the Japanese Meteorological Agency. The United States Geological Survey issued a red alert for Thursday's quake, putting the estimated financial damage between $1 and $10 billion.
The USGS is classifying Thursday's quake as a foreshock.
While weather is not expected to hinder immediate cleanup efforts, a soaking rain and gusty winds on Saturday night may create hazardous conditions.
Dry weather will return on Sunday, with light rain on Monday.
