Key Points

Paleoseismic evidence shows directivity for the 1976 Motagua earthquake, impacting seismic hazard assessment.
Sediment coring and analysis provided details on earthquake modeling that enhance our understanding of seismic activity.
Analysis included age-depth modeling to establish a timeline for seismic events in the region.
The research contributes to the understanding of earthquake behavior, highlighting the need for better models in seismic assessments.

Implication

Paleoseismic analysis reveals directivity patterns in the 1976 Motagua earthquake, indicating significant seismic behavior.

Abstract

Descriptions of seismic data acquisition, sediment coring and analysis, age-depth modeling, earthquake modeling procedures, and numerous figures and tables illustrating lake surveys, core scans, age models, and rupture simulations.
