The Greek government is diligently looking for replacement housing for the migrants from the devastated Moria camp on Lesvos.
The asylum seekers are accommodated, among other things, on ships.
The largest refugee camp in Europe housed more than 12,000 people, far more than the 2,800 for which the camp was intended. During the night fires, thousands of migrants fled.
As far as is known, no one was seriously injured.
Migration Minister Notis Mitarakis says the most vulnerable people can spend the night from Wednesday to Thursday on a ferry. Two naval ships are expected on Thursday.
People can also be accommodated onboard.
