Abstract A reassessment of the macroseismic intensities was performed for the Tumaco (December 12th, 1979, Mw = 8.1) and Armenia (January 25th, 1999, Mw = 6.1) earthquakes, based on the spatial distribution and quantification of dimensions of the surface geological and environmental effects in lists compiled from published documents. The newly constructed lists of 46 effects for the Tumaco earthquake (TE) and 123 effects for the Armenia earthquake (AE) were obtained by literature review and systematic searches of information in authoritative sources. The geological and environmental effects caused by the two earthquakes were then used to estimate seismic intensities and construct new isoseismal maps following the methodology of the ESI-2007 scale. Comparisons were made between the ESI-2007 isoseismal maps and those using data from traditional intensity scales (Modified Mercalli MM-31 and EMS-98) in terms of the percentage overlap between affected areas for each intensity level. For the AE, the newly computed intensities indicate epicentral intensity I0AE = 10 and the ESI-2007 intensities show best agreement with EMS-98 values, with a maximum of 54.2% overlap for intensities in the range 7–8. The new isoseismal maps for the TE indicate maximum intensity IMaxTE ~ I0TE = 11 and best agreement with MM-31 values, with a maximum of 48.8% overlap for intensities in the range 7–8. It is concluded that ESI-2007 intensities exhibit close agreement in most cases with MM-31 and EMS-98 values and provide new details for maximum intensities and the extent of affected areas which can be used in future plans of land use for earthquake-prone areas in Colombia.

使用 ESI-2007 标度重新评估哥伦比亚两次地震的宏观地震强度：图马科 (1979, Mw = 8.1) 和亚美尼亚 (1999, Mw = 6.1)

摘要 对 Tumaco（1979 年 12 月 12 日，Mw = 8.1）和亚美尼亚（1999 年 1 月 25 日，Mw = 6.1）地震的宏观地震强度进行了重新评估，基于地表地质和尺度的空间分布和量化。根据已发表文件编制的清单中的环境影响。图马科地震 (TE) 的 46 种影响和亚美尼亚地震 (AE) 的 123 种影响的新构建列表是通过文献查阅和权威来源的信息系统搜索获得的。然后使用两次地震引起的地质和环境影响来估计地震强度并按照 ESI-2007 标度的方法构建新的等震图。在 ESI-2007 等震图和使用传统强度标度（Modified Mercalli MM-31 和 EMS-98）数据的等震图之间，就每个强度级别受影响区域之间的重叠百分比进行了比较。对于 AE，新计算的强度表明震中强度 I0AE = 10，ESI-2007 强度显示与 EMS-98 值的最佳一致性，7-8 范围内的强度重叠最大为 54.2%。TE 的新等震图表明最大强度 IMaxTE ~ I0TE = 11 并且与 MM-31 值的最佳一致性，对于 7-8 范围内的强度，最大重叠率为 48.8%。
