"It's louder than thunder" and "I thought there was an earthquake"...A series of reports of explosions.

[Anchor]
Witnesses at the scene of the POSCO fire said they heard loud explosions.

There were also informants that it was louder than the sound of thunder or that they thought there was an earthquake.

I'll listen to it myself.

[Seo Jae-min/Posco Fire Witness: I heard explosions five or six times, so I woke up and saw that there was a lot of fire. The explosion was loud, so I think it was a little louder than the sound of thunder.]

[Posco Fire Witness] I woke up when I heard an explosion while I was sleeping. I thought there was an earthquake. So I looked at it, at first, flames were rising and smoke was rising. It will take about 30 minutes by car (to the fire).]
