There is a correlation between El Nino and La Nina cycles and global seismic activity
Recent geophysical literature supports a correlation between El Nino and La Nina cycles and seismic or microseism activity, linking climate-driven oceanic changes to shifts in crustal stress and seismic periodicity.
Papers [0] and [3] both present direct evidence and historical analyses connecting El Nino-Southern Oscillation (ENSO) variability and sea-surface temperatures to seismic signals and earthquake periodicities, thereby supporting the claim.

This study demonstrates regional-to-global associations between seismic amplitude variations and El Nino and La Nina events.

This research reveals that multidecadal seismic periodicities align with tropical sea surface temperatures and ENSO dynamics, indicating a coupling between climate variability and crustal stress regimes.
