The authors would like to make the following corrections about the published paper [1]. The changes are as follows:
- (1)
- To clearly indicate former coal mine in Houthalen (Belgium), the authors wish to add an explanation along with a reference in “Section 1 Page 3 Paragraph 6”.
Replacing the original version:
The next case concerns former coal mines in Houthalen (Belgium). The authors, using ERS 1/2 and Envisat data, obtained a picture of ground movements 18 years after the end of mining operation there. The ground motions ranged from −5.5 mm/a for the 8–9 year period and +8.6 mm/a in the following seven years. The authors claimed that the observed surface motions cannot be correlated with mining areas, as the locations of the mined coal fields did not spatially match with the areas of greatest subsidence.

The next case concerns former coal mine in Houthalen (Belgium) [10]. The authors, using ERS 1/2 and Envisat data, obtained a picture of ground movements during the 18 years following the end of mining operation there. The average ground motion was −5.5 mm/a within a zone of 2 km2 for the first 8–9 year period and +8.6 mm/a in the last seven years of observation.
