A data logger using static CMOS-type nonvolatile random-access memory (RAM) is described. Its compactness and low requirement of electric power allows outdoor use with battery operation for a period of more than 1 year. The device provides a low-cost strategy for field monitoring of the surface manifestation of volcanic activity or earthquake precursors.
