Multidisciplinary approaches for the characterization of deep-seated landslides (DSLs) are useful in comprehending the internal and external dynamics of the phenomena. This paper examines and characterizes the active Cañón de Yerbabuena DSL (in Ahualulco, San Luis Potosi, Mexico), for which there are over 30 years of damage records to Federal Highway 63. Hence, the integrated study carried out includes lithological and structural characterization, geomorphological mapping, Persistent Scatterer Interferometry (PSI) analysis, and electrical geophysical surveys. The slope deformation extends over the highly weathered and fractured volcanic rocks of the Ahualulco Volcanic Complex in an area comprising 741,000 m 2 and mobilizes an estimated rock volume of 6,950,459 m 3 . Geomorphological features within the DSL include a counter-scarp, minor scarps, tension cracks, small landslides, avalanche breccias, toppling, and colluvial deposits. Furthermore, the velocity rate in the upper section of the slope reaches up to 10 mm/year with a linear behavior that changes to a faster non-linear deformation (up to 30 mm/year) in the middle-lower part of the DSL. This change is the result of a multiple-complex dynamic linked to the presence of two normal faults fragmenting the middle section of the slope and an interbedded volcaniclastic clayey-siltstone layer acting as a possible sliding plane; the latter being defined by a resistivity survey. The acceleration of the velocity rates at the foot of the DSL are linked to torrential rains in the area and cause the most severe damage to the highway. Furthermore, the general slow deformation within the DSL is triggered by severe erosion from the seasonal river at the foot and the run-off on both flanks.

描述半干旱地区深部滑坡特征的多学科方法（Cañón de Yerbabuena，San Luis Potosí，墨西哥）

表征深部滑坡 (DSL) 的多学科方法有助于理解该现象的内部和外部动态。本文检查并描述了活跃的 Cañón de Yerbabuena DSL（位于墨西哥圣路易斯波托西的 Ahualulco），其对 63 号联邦公路有超过 30 年的损坏记录。因此，进行的综合研究包括岩性和结构特征，地貌测绘、持续散射干涉测量 (PSI) 分析和电子地球物理调查。斜坡变形延伸到了 Ahualulco 火山复合体的高度风化和破碎的火山岩，面积为 741,000 m 2 ，估计移动了 6,950,459 m 3 的岩石体积。DSL 内的地貌特征包括反陡坡、小陡坡、张力裂缝、小型滑坡、雪崩角砾岩、倾覆和崩积沉积物。此外，斜坡上部的速度达到 10 毫米/年，线性行为在 DSL 的中下部转变为更快的非线性变形（高达 30 毫米/年）。这种变化是多重复杂动力的结果，这与两个正断层的存在有关，两个正断层分裂了斜坡的中间部分，夹层火山碎屑粘土-粉砂岩层作为可能的滑动面；后者由电阻率测量定义。DSL 脚下的速度加速与该地区的暴雨有关，并对高速公路造成最严重的破坏。此外，
