Deformation History

There is data available for 1 deformation periods. Expand each entry for additional details.


Deformation during 1990 - 2003 [Subsidence; Observed by Leveling]

Start Date: 1990 Stop Date: 2003 Direction: Subsidence Method: Leveling
Magnitude: Unknown Spatial Extent: Unknown Latitude: Unknown Longitude: Unknown

Remarks: Leveling surveys reveal subsidence of the northern and southern flanks of the Mt. Epomeo resurgent block. The deformation is likely due to crack closure of the hydorthermal system.

Figure (see Caption)

Vertical displacements recorded along the Coastline (blue), Borbonic line (green) and Casamicciola-Chiummano line (black) from 1990 to 2003. Numbers are the benchmarks.

From: Sepe et al. 2007.
