Definite risk. Quake happened on Swan Island transform (south side of 6 km deep Cayman Trough). Undersea landslide could have occurred (Tsunami watch (NOT WARING) was issued as conditions favorable (magnitude and water depth) for tsunami was present. Luckily it did not. See USGS site for details. Landslides and tsunami can also be triggered by aftershocks.

There is no local warning system. No paleotsunami studies along the north coast of Honduras.

Aftershocks are real and likely to happen for next few weeks. Heightened awareness should observed in coastal zones……. If a sudden low tide happens, it’s time to find high ground.

Any risk of tsunami?, is the area prepared for this sort of event? is there a system of alert for tsunamis?, any studies reporting paleo tsunamis, anywhere in the area?
Please directo me to those sources.
Thanks
