Oregon - Surviving and Earth Quake and Tsunami

Direct from the state of Oregon.


NEWS RELEASE: February 28, 2012

Is your family ready to survive an earthquake and tsunami?


Portland, Oregon: Recent earthquakes offshore of Japan and Chile and the
Haiti earthquake remind us that we live in an unstable world and that
everyone needs to be prepared for natural disasters. Scientific evidence
suggests that there is a 10% probability that a Cascadia Subduction Zone
event offshore Oregon will happen in the next 30 years.

To help raise awareness, Governor Kitzhaber has proclaimed March 2012 as
Earthquake and Tsunami Awareness Month in Oregon.

You cannot prevent the next earthquake, tsunami, or other disaster but you
can get ready. Even under the best of circumstances, medical aid and first
responders may not be able to reach you for hours, or even days. In a
disaster, local resources can be overwhelmed. Japan is the most
technologically-advanced country in the world, but two weeks after the
earthquake and tsunami of March 11, 2011, some areas were only just being
reached. It is our responsibility - as individuals, families, neighborhoods
and communities - to reduce risks beforehand, prepare for the critical
period immediately after the earthquake or tsunami and to make sure that
planning for disasters has the high priority it deserves.

Have you made sure that your family, friends, and neighbors will survive if
an earthquake or tsunami strikes?

The Oregon Department of Geology and Mineral Industries (DOGAMI) is funded
by the NOAA National Tsunami Hazards Mitigation Program (NTHMP) to mitigate
tsunami risk in Oregon by accurately mapping the tsunami inundation hazard
zone, increasing awareness of where the zone is and what the warning signs
will be for the approaching tsunami, and enhancing formal preparedness and
evacuation planning with local authorities and stakeholders through its
Tsunami Outreach Oregon campaign. Many events are planned for March -
participate and learn how to be prepared!

Fire Making

Here is my go-to fire making method for survival situations and how to use it.

by Leon Pantenburg

It has been over 10 years since I started any wilderness campfire using any ignition method other than flint and steel.

Part of the reason is that I like to keep my survival skills polished, and the other is that flint and steel is just so effective. I’ve used the method successfully in driving rain and snow, wind and zero degree temperatures. But the old time method would not be my first choice as a survival fire making tool during an emergency.

My number one choice is a combination of cotton balls infused with petroleum jelly and ignited with a magnesium stick.

Norwegian Mountain Code

I enjoy reading about backcountry travel. I am also interested in what is the right gear to carry.

I came across the Norwegian Mountain Code last year.

It's pretty simple.

In 1967, Norway tragically lost 18 outdoors men during the Easter weekend. Later the Norwegian Red Cross and Norwegian Mountain Touring coordinated the development of the code; a common sense approach to back country winter travel.

The code compliments the Ten Essentials and builds on it. Read about the code here.

Trip Panning

Are you prepared for a bad turn of events on your hike?

The hikers had planned well for the trip.  They had purchased their maps and trail guide.  Late night internet searches produced tips, pictures and camp site suggestions.  They were ready to go.  But were they ready for the unexpected?

The unexpected happens even for the best prepared.  Accidents just happen.  I’d like to cover a few topics that we might not think of or practice as we should.

There are three topics that I’d like to cover.

First, always let a responsible person know of your plans.  Pick a person whom you know can be decisive and make a judgment call.  If you tell the responsible person that if you aren’t home to call 911 for Search and Rescue (SAR) at 9:00, you know that at 9:01 that person is on the phone making a very difficult call.  But help that responsible person out.  Give them and the searchers something to go by.  The Boreal Wilderness Institute (BWI) of Alberta, Canada offers a fine trip card on their site at www.boreal.net.  On my web site I provide what I call the Hiker’s Trip Plan at www.outdoorquest.biz.  Remember that rescuers would like know about the number of hikers in the party, medical conditions, and what animals are accompanying the group.

Secondly, have a back-up plan should your GPS break or become lost.  That doesn’t mean that the trip has to end but the backcountry navigator certainly needs to understand what the options are.  For a deep wilderness trip where the hiker is bushwhacking off trail this becomes more important.  Better still; a backup plan begins before leaving home.  The BWI Route Card includes a section for route planning notes and an escape route.  The Outdoor Quest plan has a section for an alternate route.  It is this data that will help a SAR team to focus and provide containment for the search.

Certainly a second GPS in the party will make a difference for the better.  That said, having a sound knowledge of map and compass procedures is absolutely essential.  All deep wilderness hikers need to have a solid navigation foundation.  I always recommend to my students in my land navigation classes to start practicing two weeks before the big trip.  Take the GPS and compass everywhere.  Mark waypoints, edit waypoints, sight on distant objects with the compass and run a bearing.  The hiker needs to develop the muscle memory for the GPS and recall the logic of placing the magnetic needle over the orienting arrow (e.g., red in the shed, mouse in the house.)  The web site www.landnavigation.org offers a very good review of the fundamentals to navigation.

Third, BWI web site offers a short discussion about an “escape route.”  The hiking group should reflect on the many contingencies that can come into play during a backcountry trip.  Weather, terrain, injury and wild land fires come immediately to mind.  For example, in the Central Oregon Cascade range, the mountainous slopes have vast expanses of beetle killed trees.  Dry summers produce large fires that grow quickly becoming an obvious hazard.  The point is to develop options that should the need arise, evacuation is a matter of choice and planning.  BWI comments that “An escape route is a simple bearing toward a major highway, road or other linear feature.”  Everyone in the party must have an understanding of the geography and terrain.  Should the group need to “bug out,” terrain needs to be used to the groups advantage rather than being channeled in the wrong direction and away from safety.

Cascadia Megaquake

Japan quake studies suggest harder jolt to NW possible

Studies of last year's giant Tohoku earthquake and tsunami in Japan suggest that shaking from a Cascadia megaquake could be stronger than expected along the coasts of Washington, Oregon and British Columbia, researchers reported Sunday at the annual meeting of the American Association for the Advancement of Science.

Quantcast
VANCOUVER, B.C. — Scientists are still unraveling last year's giant Tohoku earthquake and tsunami in Japan, and some of what they're finding doesn't bode well for the Pacific Northwest.

Detailed analyses of the way the Earth warped along the Japanese coast suggest that shaking from a Cascadia megaquake could be stronger than expected along the coasts of Washington, Oregon and British Columbia, researchers reported Sunday at the annual meeting of the American Association for the Advancement of Science.

"The Cascadia subduction zone can be seen as a mirror image of the Tohoku area," said John Anderson, of the University of Nevada.

Anderson compiled ground-motion data from the Japan quake and overlaid it on a map of the Pacific Northwest, which has a similar fault — called a subduction zone — lying offshore.
In Japan, the biggest jolts occurred underwater. The seafloor was displaced by 150 feet or more in some places, triggering the massive tsunami. But in the Northwest, it's the land that will be rocked hardest — because the Pacific coast here lies so close to the subduction zone.

Managing GPS Waypoints

Most GPS receivers sold on the market today will hold 500 waypoints in memory. These waypoints are your saved/recorded geographic locations that you have saved into the receiver's memory. A waypoint could be the saved location of your camp or truck.

So, just how many waypoints should you have saved? On my GPS I probably have about 5 and 0 would be better.

I like to keep my navigation simple and having hundreds of saved waypoints is can be a headache.

Finding North

Finding North to Help You Stay Found

by Peter Kummerfeldt
It is easy to find yourself a bit disoriented and, lacking a compass or other navigational equipment, being unable to figure out which way to travel to go home! One of the fundamental skills that an experienced outdoors man or women relies on is the ability to determine the cardinal directions (North, East, West and South) from the sun or from Polaris - the North Star. Blake Miller of Outdoor Quest has done a great job of showing you how to use Polaris to determine North and then based on knowing where North is, determine East, West and South. Check out his blog But what about during the daytime when you can't see Polaris? What can be done then to help you determine your way back to your truck?
