Re: Petra's Ear Tone Advisory Wrong One

Hi Lowell,

You're referencing the wrong prediction/advisory. See this post:

Triple Junction & Markleville to Mammoth Quakes

Hi All,

Yesterday evening just after 5PM I was treated to another unusual ear tone event. Both of my ears were giving me similiar sounds at the same time and ended at the same duration. I was a little puzzled and then I was talking to Don about it and he mentioned is forecast for off the coast of Oregon. So I went there just now to find it and see if it had any similarity to my expected northern quake. Here's his forecast:


Earthquake Forecast Off Oregon Coast
Posted by Don in Hollister on June 12, 2001 at 13:43:01:
Magnitude: 4.5-6.0
From: 06/30/2001PDT - To: 07/05/2001PDT
Location: 225 miles west of Eugene, Oregon
Lat: 43.4N - Long: 127.7W - Range: 70Km

My ear tones last around 5 seconds so that puts the distance for me at the north coast area, and to the right Markleville to Mammoth. So the ear tones do not support his prediction.

As I can only hear certain magnitudes at given distances, each of these probably quakes would be in the 4.0+ range and should occur either within minutes or hours of each other.

This should be good watching to see what actually shows up. But being that I have a distinct window problem, I'm going with 6/30 to 7/15.

So if his quake is coming, then there remains the possibility if it is higher than a 4.0 I may indeed hear it before it arrives, so I'll let you know if anything happens.

In this post I missed window #1 and got window #2.

The other hit was associated with Vancouver Island, dealing with a separate post that you were referencing and was a lower magnitude than expected. 1 under. I thought 5.5 and it came in at 4.5.

Not bad, but not really good either.

However, Don thought that the quake in the Truckee area and the quake in his area fit this posted prediction far better. They were within a day of each other, if not on the same day.

Sometimes its not good when you get to many quakes at one time, you get more than one possibility to have a match and arean't sure which one it was.
