causes

The earthquake occurred in the northwest of the Lower Rhine Bay , which continues to the northwest in the central ditch of the Netherlands. The geology of the Lower Rhine Bay is determined by the continuing expansion of the earth's crust , so that the crust has broken into individual clods along faults running from northwest to southeast . The movements occurred mainly on large fault systems, the largest the field bite -Verwerfung which Rurrand - Peelrand jump , the Erft jump and Viersener jump are. The earthquake in Roermond was due to a movement of the Peelrand jump, the northeast boundary of the Rurgraben , where the southwest clod sank by about half a meter.
