00:00around the area. So the police confirmed that there was an activity of earthquake that
00:08has occurred before the incident and the work is to replace the pumping pipe which is more
00:23or less 30 meters from the epicenter. So the police have identified the developer, the
00:36contractor, the subcontractor and the involved workers who use two generators, one is a backhoe
00:43and the other is an excavator, which has been used to dig the ground in the area to replace
00:52the existing pumping pipe. And the work was stopped on March 30. So the result of the
01:05police investigation is that one of the excavators was sunk in the hole. Is there any activity
01:22of earthquake that can cause an explosion? This is something that needs to be investigated
01:28further. It still needs time to find out. We can confirm that there is an activity of
01:36earthquake, but how deep is the earthquake and how far does it need to be investigated?
01:45And then we need to make sure whether the activity can cause the explosion.
