摘要：

We present natural examples and experimental models of volcanic cones located above brittle substratum undergoing regional compressive deformation. The volcanic loading induces a strain partitioning involving deflection and flattening of regional compressive structures. The main control is the topographic load. Anticlinal thrust ridges, observed around many volcanoes, have generally been interpreted as being due to gravitational spreading; however, this study shows that this is not necessarily the case, as they can also be a symptom of regional compression.
