图1|初步应力扰动图（在10公里深处计算）覆盖在震源区卫星雷达地形使命数字高程模型上。色标表示库仑应力的变化。正应力区可以被认为具有较高的余震概率。星号表示Ziarat地区两次6.4级地震的位置;第一次事件的位置（1）是第一次公布的计算应力场的位置。第二个事件（2）的位置是当前最佳估计。USGS-NEIC报告的震源机制解（白色“海滩球”）也显示出来。圆圈表示有风险的定居点的位置。插图：地震的区域背景-星星表示主地图中显示的区域位置。
Figure 1| Preliminary stress perturbation map (calculated at 10 km depth) overlain on the Satellite Radar Topographic Mission digital elevation model of the earthquake source region. The colour scale indicates the Coulomb stress change in bars. Areas of positive stress can be considered to have an elevated aftershock probability. The stars indicate the locations of the two magnitude-6.4 earthquakes in the Ziarat district; the location of the first event (1) is the first published location for which the stress field was calculated. The location of the second event (2) is the current best estimate. The focal mechanism solutions (black-and-white ‘beach balls’) reported by USGS-NEIC are also shown. The circles show the location of settlements at risk. Inset: The regional context of the earthquakes—the star indicates the location of the area shown in the main map.
