Seismicity and seismically active faulting of Guatemala: A review

We present a review of the main sources of seismicity of Guatemala. The largest seismically active faults are related to the transform, left-lateral, North America-Caribbean plate boundary zone, the most prominent of which are the Motagua and Polochic faults, both exceeding 350 km in length. Additionally, the Ixcán fault, a 150-200-km-long left-lateral structure, is located north of the Polochic and Motagua faults. Other seismically active faults associated to the Polochic-Motagua system and smaller in length are the Seleguá, Nentón and Las Conchas.
