The crater is partially obscured by cloud.The extent of the mud lake is 600 ha (6 km²). The average rate of expansion of the lake is 2.3 hectares a day since the start of the eruption. The dams and retention basins have overflowed. New ones have been built further from the crater.

The road and railway, as well as buildings around the crater, are submerged. The lake is expanding mainly northward (after the gas pipeline explosion) and southward. Rainy season precipitation is running off the mud toward agricultural irrigation channels (orange arrows).

Nearly 1 year after the eruption started (29 May 2006), the dams around the volcano have contained the mud flow since January 2007.
But the dams are showing signs of cracking in the satellite image.

The extent of the mud lake has increased from 600 hectares (6 km²) to 604 hectares after a dam collapsed.

The average rate of expansion of the lake has slowed to 1.6 hectares a day since the start of the eruption.

[1] The crater has widened to nearly 70 metres.The extent of the mud lake is unchanged: 600 hectares (6 km2). The average rate of expansion of the lake has slowed to 1.7 hectares a day since the start of the eruption.
[2] More buildings have been submerged.

[1] The dam around the crater has been breached on its south side to divert the mud flow.
[2] A 1st channel formed by two parallel dams diverts the mud flow into a small retention basin.
[3] A 2nd channel connects the mud lake to the Porong river.
[4] The mud is changing the colour of the water in the Porong river.

1 year after the start of the eruption (29 May 2006), the mud flow has reached buildings now submerged inside the maximum extent zone (green line).

The extent of the mud lake is unchanged at 604 ha. The average rate of expansion of the lake has slowed to 1.55 ha a day since the start of the eruption.

[1] The north basin is flooded and buildings are now completely submerged by mud and runoff waters.
[2] A new dam and retention basin are being built to the west of the crater.
[3] The south-west basin is being used to attempt to dry the mud.
[4] New retention basin.

[3] The west dams have been consolidated.
[4] Experimental earthworks.
[5] A new dam is being built to the east for a vast retention basin.
