Time series of the volcano’s evolution
Airbus Defence and Space has been tasking the FORMOSAT-2 satellite since January 2007 to acquire imagery and track the Lusi mud volcano eruption. Two SPOT 5 images are being used as the baseline for comparison: one from 2005 before the eruption and the other from 7 August 2006. The volcano started erupting on 29 May 2006.

The volcano is near a railway and highway in farmland near small-scale industrial facilities. There are many villages in the area and a large, recent housing estate to the north of the crater.

The crater can be identified with the smoke plume and mudflows all around. The extent of the mud lake is 230 hectares (2.3 km²). The average rate of expansion of the lake is 3.3 hectares a day since the start of the eruption. The holding dams and basins built to contain the mudflow are most clearly visible to the north and south of the crater. The road has been damaged but is not submerged. The railway is still untouched.
