丹麦最近的地震学项目涉及新构造调查和结构研究，确定了丹麦下面的波罗的海地盾边缘。丹麦最活跃的地震带位于日德兰西北部和邻近的近海地区，以及卡特加特、厄勒海峡和西兰东北部地区（图1）。这一模式最初由Lehmann（1956年）确认，并被后来的几项研究所证实，例如Gregersen等人（1998年）。最近，更详细的调查表明，地震活动模式的变化发生在很短的时间跨度内。最明显的变化例子-可能与碳氢化合物的开采有关-是在北海中央地堑地区记录的一项活动，该活动最早由Gregersen等人（1998）记录。
Recent Danish seismological projects involving neotectonic investigations and structural studies have determined the edge of the Baltic Shield underlying Denmark. The most active earthquake zones in Denmark are located in northwestern Jylland and adjoining offshore areas, and in the region around Kattegat, Oresund and north-east Sjaelland (Fig. 1). This pattern was originally recognised by Lehmann (1956) and has been confirmed by several later studies, e.g. Gregersen et al. (1998). Recent, more detailed investigations have documented that changes in the pattern of earthquake activity have occurred within a short time span. The most pronounced example of change ‐ possibly related to exploitation of hydrocarbons ‐ is an activity recorded in the Central Graben area of the North Sea that was first documented by Gregersen et al. (1998).
