Stress Map Iceland 2016

The stress map of Iceland shows the orientation of the current maximum horizontal stress (SHmax) in the earth's crust. Assuming that the vertical stress (SV) is a principal stress, SHmax defines the orientation of the 3D stress tensor; the minimum horizontal stress Shmin is than perpendicular to SHmax. In the stress map the SHmax orientations are represented as lines of different lengths. The length of the line is a measure of the quality of data and the symbol shows the stress indicator and the color the stress regime. Data with E-Quality are shown without additional information as dots on the map. The stress data are freely available and part of the World Stress Map (WSM) project. For more information about the data and criteria of data analysis and quality mapping are plotted along the WSM website at http://www.world-stress-map.org.

冰岛应力图展示了地壳内当前最大水平主应力（maximum horizontal stress, SHmax）的方位。假设垂直应力（SV）为主应力，则SHmax可确定三维应力张量的空间取向；最小水平主应力Shmin与SHmax相互垂直。在该应力图中，SHmax的方位以不同长度的线条表示：线条长度用于表征数据质量，符号代表应力标识，颜色则对应应力体制。带有E级质量的应力数据将以地图上的点标记呈现，不附带额外说明信息。此类应力数据可免费获取，属于全球应力图（World Stress Map, WSM）项目的组成部分。如需了解该数据、数据分析准则及质量制图方法的更多详情，请访问WSM官方网站：http://www.world-stress-map.org。
