M 8.8 Maule, Chile earthquake of 2010
Although this was the 5th most intense earthquake on record, I observed relatively little damage owed in part to the fact that a significant portion of the infrastructures were built to survive intense earthquakes. Here there are some interesting photos.
The base station on the left shows clear signs of damage, the most evident of those is the fallen door. Some inadequate battery rack and anchoring is exemplified on the right.
A common problem was fallen or misaligned antennas exemplified with these photos. The one of the left shows antennas on the ground, while the one on the right shows technicians working on top of a tower.
A few base stations were affected by falling walls.
Poles are made of concrete so most of them were able to resist debris from falling structures nearby, as shown in these two photos. More common was failures due to damaged drops as the photo on the right exemplifies. Most of the damaged poles were found in areas affected by the tsunami, as exemplified in the next 4 photos:
In some areas poles were affected by ground movement.
Two views of a CATV UPS in Concepcion. It is unclear if the batteries were missing because they felt during the earthquake or because they were stolen.
One of the relatively few cell sites with portable gensets. This one was south of Concepcion Airport.
Some common views after hurricanes in the US, but not as common in Chile. From left to right a DLC remote terminal, a damaged SAI, and a COW.
These two were pictures from the only substation were there was some concentrated (but not critical) damage
