In this work, we analyze the performance of network‐based and stand‐alone (on‐site) early warning systems during the 2016–2017 central Italy sequence, characterized by events with magnitude as large as 6.5. For the largest magnitude event, both systems predict well the ground shaking nearby the event source, with a rate of success in the 85%–90% range, within the potential earthquake damage zone. However, the lead time, that is, the time available for security actions, is significantly larger for the network‐based system. For the regional system, it increases to more than 10 s at 40 km from the event epicenter. The stand‐alone system performs better in the near‐source region, still showing a positive albeit small lead time (<2 s). Far away from the source (>60 km), the performances slightly degrade, mostly owing to the large uncertainty in the attenuation relationships. This study opens up the possibility for making an operational EEWS in Italy, based on the available acceleration networks, provided that the delay due to data telemetry has to be reduced.

The tectonomagnetism investigations in the earthquake region show that obvious anomalous changes in the magnetic field exist pre and co earthquakes. The seismomagnetic precursors basically are near field effects; the epicentral distances are several to tens km; the change amplitudes are several nT; the time precursors last is several days to more than one year. New progresses of the research on volcano tectonomagnetism further show that the volcano magnetic effects are closely related to the volcano activity states, such as volcano earthquake, deformation, fracture and eruption; it provides important basis and method for monitoring and predicting volcano eruption hazards. According to the physical basis of tectonomagnetism, earthquake prediction is actively carried out, showing a perspective earthquake prediction research by means of tectonomagnetism. However, it is still situated at the period of data accumulation and the trial stage, and further observation and research should be made in the future.
