Earthquake Alarm

Q: how loud is the alarm? do you have one of these on each floor of the house? one in each bedroom? only one in the whole house? thanks.

Hi, the alarm is a simple chiming buzz, it plays following the mechanical contact of the swinging pendulum against the adjacent metal frame (frame has an adjustable width in order to set the right sensitivity you wish).I think the alarm "sound pressure" is sufficient just in these two circumstances :1) If you are awake and around 6-7 meters from the device 2) If you are sleeping and the device is set close to your bed (within 1-2 meters) in my case I fixed it on the wall, half meter far from my bed, so that it will be able to wake me up. (consider that I live in apartment so it is a single-floor home. It is a 100mq. apartment, not a huge apartment. For my application I think it works fine) Being the buzzer-contact activated by a mechanical way you have the advantage the battery charge will not be used unless the quake happens. Battery will be ready for long time (will discharge just for "oldness")

Q: I live in MN where a huge quake could occur in eastern MO, and past ones have been felt further than where I am. Could this help in my situation?

YES this is the BEST case for this device.Let me be more clear.If the main focus of another giant New Madrid/MO earthquake is in MO and you are say 450 miles away (St Louis,MO to Rochester, MN border is 450 miles according to google) the earthquake alarm would feel the p waves at least 2 to 3 MINUTES (http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&ved=0CDYQFjAC&url=http%3A%2F%2Facademics.concord.edu%2Fsckuehn%2FVirtualEarthquake.pdf&ei=4Y8rUpzpNoLM9ATvzYHABA&usg=AFQjCNHc6KVy0i2IpMfXYFUnIBYsQFwWMA&bvm=bv.51773540,d.eWU) before you would otherwise feel the major shaking thus it would give you time to do something - wake up, get outside, get a door open so you aren't trapped inside etc. It works BEST in situations like yours when there is a large quake that is further away because it then gives you the MOST time warning before the later big rolling waves that will hurt you will follow.IT works LEAST well when the quake originates right under your house becuase then both waves hit you at nearly the same instant.since we know the eastern US feels the effects of New Madrid quakes far more than Los Angeles feels the effects of closer quakes we know that Earthquake damage in the Middle of america and the East could be strong as far away as MO.(the New Madrid quake rang church bells in Boston!)

Q: I live in Oregon where we have a 37% chance of a magnitude 9 or greater earthquake striking within the next 50 years. Approximately 50 miles off the Oregon coast is the Cascadia Subduction Zone where in January 29, 1700 a magnitude 9 earthquake occurred. They occur on average approximately once every 250 years and the …

today is 1/29/18, and I've read that there is now 14% chance for the 9 or greater quake within next 50 years. But Nature lives by it's own rules, and it could happen at any moment. A device like this is valuable even if you only get 10 seconds notice. That 10 seconds could save lives. Definitely get this device, and apply it to a solid post that is connected to the ground. By the way, over the last 10,000 years, the mega quakes are averaged to occur at approx 500 years apart, with significant but smaller magnatude quakes spaced in between those largest ones. But keep in mind that although some mega quakes were spaced as much as about 1,000 years apart, there were others that were only in the 200's apart, so better to be prepared in case we experience one of the shorter intervals. Who's to say for sure.
