Abstract: A method for detecting seismic events, the method including acquiring acceleration data over a given period of time from one or more accelerometers located on a grid framework structure; comparing the acquired acceleration data to ground acceleration data from one or more accelerometers located on the ground; determining a differential acceleration between the acceleration data and the ground acceleration data; determining displacement data from the differential acceleration; and determining whether a seismic event has taken place over the given period of time based on the displacement data.

Abstract: A multitemperature storage system is provided. The system includes a storage structure having a plurality of upright members, a plurality of horizontal members supported by the upright members and forming a grid pattern defining a plurality of grid cells and allowing containers to be arranged in stacks beneath the grid cells defined by the grid pattern, and a track structure on top of the horizontal members, the track structure being configured to allow a load-handling device to move across the storage structure to retrieve a container from a stack; and temperature-control means configured to maintain a first-temperature region within the storage structure at a first temperature and a second-temperature region within the storage structure at a second temperature.
