The USGS issued a Green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.

Overall, the population in this region resides in structures that are highly vulnerable to earthquake shaking, though some resistant structures exist. The predominant vulnerable building types are mud wall and adobe block construction.

Recent earthquakes in this area have caused secondary hazards such as landslides that might have contributed to losses.

  1. Greetings!
    Thank you for all the great work you do!! I did notice that there was a mis-print in your article. In the first paragraph it states that the earthquake hit near Panama. All the maps seem to show it off the coast of Nicaragua.
    Just thought I would mention it.
    Best Regards,
    MG
