Lacustrine Paleoseismology

Paleoseismic histories derived from lacustrine sediments have become increasingly common for determining past seismic activity. Lake basins in tectonically active regions can preserve indirect evidence of past earthquakes due to coseismic shaking, which mobilizes and reworks sediment in the lake and its catchment, and results in diagnostic deposits in the sediment stratigraphy. The ability to construct continuous, precisely-dated, and temporally long paleoseismic histories from lakes makes them strong complements to other paleoseismic methods, such as fault scarp trench exposures, which can provide more direct evidence of surface rupturing earthquakes (including rupture age and surface displacement), but which can be discontinuous and/or temporally restricted to recent rupture events and typically have large dating uncertainties.
