The Internet Accelerograph IA-2 expands the era of its predecessor IA-1. It complements the GeoSIG instrument NetQuakes / GMS in the urban seismic research and engineering, which requires a high spatial density of seismic instruments. For major urban centres several hundred instruments are required. Thus unit costs as well as operating costs are of major concerns.

The state of the art, all-in-one IA-2 offers a substantially lower cost solution when compared to any other equipment doing the same job. Since the instrument and communication design takes advantage of the latest micro electronic technology in design and the existing Internet infrastructure for station management, data retrieval and event-reporting; network operating costs drop to a small fraction of conventional strong-motion seismograph networks.
