Maritime Tsunami Response Guidance (MTRG)

Guidance for operators of small watercraft and commercial fishing vessels in the event of a distant tsunami.

DOGAMI Maritime Tsunami Response Guidance (MTRG) series publications offer operators of small craft such as recreational sailing and motor vessels and commercial fishing vessels guidance in the event of a distant tsunami. Distant tsunamis are caused by great earthquakes far away from the Oregon coast and will strike approximately four or more hours after the earthquake.

The series is part of ongoing efforts to increase tsunami awareness and preparedness in Oregon’s maritime community. The statewide maritime guidance for all types of tsunamis is contained in the brochure “Tsunami! What Oregon Boat Owners Need to Know.” The statewide brochure offers information about response and readiness for a local Cascadia Subduction Zone earthquake and tsunami, which would strike the coast in as little as 10 minutes.

Development of the first MTRG guide was funded by the National Tsunami Hazard Mitigation Program and supported by DOGAMI, the Oregon Office of Emergency Management, the Virginia Institute of Marine Sciences, the National Oceanic and Atmospheric Administration, and members of the Oregon Marine Advisory Council.
