Query: The theoretical and practical foundations of strong earthquake
  predictability   This paper provides theoretical and practical arguments regarding the
possibility of predicting strong and major earthquakes worldwide. Many strong
and major earthquakes can be predicted at least two to five months in advance,
based on identifying stressed areas that begin to behave abnormally before
strong events, with the size of these areas corresponding to Dobrovolsky
formula. We make predictions by combining knowledge from many different
disciplines: physics, geophysics, seismology, geology, and earth science, among
others. An integrated approach is used to identify anomalies and make
predictions, including satellite remote sensing techniques and data from
ground-based instruments. Terabytes of information are currently processed
every day with many different multi-parametric prediction systems applied
thereto. Alerts are issued if anomalies are confirmed by a few different
systems. It has been found that geophysical patterns of earthquake preparation
and stress accumulation are similar for all key seismic regions. The same
earthquake prediction methodologies and systems have been successfully applied
in global practice since 2013, with the technology successfully used to
retrospectively test against more than 700 strong and major earthquakes since
1970.
