Link between ~6.0 Mb earthquakes and geomorphological transformations in the Tarauacá fault region

Ascertain whether earthquakes with magnitude around 6.0 Mb can explain the geomorphological transformations recently observed in the Tarauacá fault region of Acre, Brazil, by developing and analyzing appropriate theoretical models.

Background

Crisóstomo (2023) observed rapid geomorphological changes in the Tarauacá fault region over a short time span, attributing an important role to local neotectonics. The authors of the paper question whether earthquakes of approximately 6.0 Mb could account for these transformations.

They present this as an explicit question and suggest that theoretical studies are needed to test the hypothesis, indicating it remains unresolved.

References

Finally, according to the argument of Crisóstomo (2023), is it possible that earthquakes with a magnitude around 6.0. Mb explain the geomorphological transformations recently observed in the Tarauaca fault region? Theoretical studies should be conducted to verify this hypothesis.
