What Are the Advantages of today's Networks?

Many of the seismic sensors employed in today’s networks are weak-motion devices, able to detect seismic events far below human perception, thus providing the very high precision required for much seismological research. Strong-motion systems are rapidly being upgraded to state-of-the-art digital systems, in order to provide seismic information to the emergency management teams as fast as possible after an event.

In many cases, state-of-the-art communication facilities like ISDN (integrated systems digital network) or CDPD radio modems (cellular digital packet data) are employed for data collection. Data distribution is generally accomplished by directly connecting the servers of the seismic networks to the internet. Thus, viewers all around the world have been a chance to observe Californian seismic activity in near real time.
