Much of the geology of the area formed when the Xitle volcano erupted in 100 CE, which created numerous caves and formed the basis of the volcanic soil that, 600 years later, makes the area's agriculture so productive. The borough has two types of soil: rocky in higher elevations and—in lower areas—less solid and containing more groundwater, making it somewhat spongy. The area experiences regular seismic activity, mostly of low intensity, which is believed mostly from small ancient faults reactivated by regional stresses, or by the sinking of the Valley of Mexico. The south of the Valley, including Tlalpan, is also affected by the underground movement of magma, especially when such contacts the waterlogged regions of the former Lake Xochimilco. Most of these tremors go unnoticed except for those that occur close to the surface such as the one centered 5 km south of the Ciudad Universitaria on 16 October 2005 (mag. 3.1). However, even this one was not felt far from its epicenter. Three areas in the borough are susceptible to seismic activity over 7.5 on the Richter scale: Colonia Isidro Fabela, Villa Coapa, and Tlalpan Centro. These areas are subject to special building inspections and annual earthquake drills. The borough has a warmer and more humid climate than the rest of Mexico City.
