Sun, 22 Mar 2026 00:00:00 GMT

The 2007 collapse drove home a truth that cities built on volcanic terrain must eventually confront: the ground is not as solid as it looks. Guatemala City's foundation is geologically young, composed of material that has not had time to cement into hard rock. Every pipe leak, ev...
