Subject: PSN: Updated Seismometer Details From: "kpayea" kpayea@........... Date: Mon, 30 Jun 2003 15:48:52 -0700 Hello All: Many of you requested details of the spring mounting as well as recordings from my vertical seismometer modeled after the STM-8. I have added a spring details page: http://www.bryantlabs.net/VSeisSpring.html This may take a while to download due to the large jpeg's. and a page with a couple of recordings: http://www.bryantlabs.net/SeisTraces.html Has anyone archived/mirrored a copy of Sean-Thomas's pages for future reference? Some day soon, a sysadmin at SLU will "clean house" and that stuff will be gone.

Date: Tue, 15 Jul 2003 16:21:50 -0400 As some of you may have heard, an educational seismology workshop is being organized for September in Baltimore. I think the experience of PSN members in working with schools and the general public would contribute significantly to the workshop, and I invite interested PSN members to apply to attend. If you have any questions about the workshop, please let me know. Regards, John Taber U.S. Educational Seismology Network Workshop Workshop information and application form now available at http://www.indiana.edu/~usesn/workshops.htm Applications to attend are due July 21. We are pleased to announce the U.S. Educational Seismology Network (USESN) Workshop, to be held at the Mount Washington Conference Center near Baltimore, Maryland on September 13-16, 2003 (full days on Sept. 14-15). The workshop will provide a forum for exchange of ideas on emerging opportunities for educational seismology in the U.S., and will result in detailed educational and operations plan for the USESN initiative. The workshop will include approximately 40 participants from the research, education, and science outreach communities. The 2.5-day meeting will include a mixture of oral, poster and discussion sessions, and will conclude with formal writing assignments for education and operations plans for the USESN. Funding for travel, housing and meals is provided by the National Science Foundation for up to 40 participants. Participants will be selected based on the applicants' potential to contribute to the educational goals of the USESN. For more information contact: Michael Hamburger, hamburg@...........

One must also coat the finished recording with a clear coating to "fix" the soot. They are a great instrument but require some delicate work to record data.

It was written for the IASPEI/Unesco Working Group on the Manual of Seismogram Interpretation (I looked in appropriate places in the publication and IASPEI was never defined). The purpose of the report is to present a comprehensive and tutorial manual for deciphering available seismograms.." The report is aimed at students in seismology, amateurs as well as more experienced persons. It has virtually no mathematics, is easy to read, has attractive illustrations and many examples of seismograms with phases identified. The introductory text consists of Earthquakes Why and Where They Occur, Structure of the Earth's Interior, Seismic Waves, Travel Times, and Seismographs and Seismological Observatories. The remainder of the report consists of interpretation of 55 plates showing various types events with phases identified. If I were to pick one of the four, this would be the one. The only problem with this one is the cost--$142. I have this book and it is one of the better investment I have made in this hobby.

Date: Sat, 19 Jul 2003 21:16:12 EDT Hi all, Here is the procedure I use to calibrate my mini-Lehman type sensor. Does anyone have any comments? Bob McClure ------------------------------ 1. Set up limit stops on the pendulum so that it can be displaced over a known and fixed number of millimeters at its radius of gyration. 2. Connect the sensor directly to the A/D, and log data as you move the pendulum gently back-and forth a few times between the stops. Record at a rate that gives a reasonable number of samples for the time taken to move between stops. Do not move so fast that you exceed the voltage range of the A/D, otherwise you won't get valid data, and you might even blow out the A/D. Also, verify that the resistance of the sensor coil is low compared to the input impedance of the A/D. 3. Make a WinQuake event file out of the data. 4. Use WinQuake to integrate the data. You should see the actual displacement versus time, measured in counts. Measure the peak-to-peak displacement in counts. 5. Scale the count measurement to what you would have obtained for one centimeter of motion. If you used 5mm of displacement, for example, you would multiply your count estimate by two. 6. Multiply the scaled counts by the voltage gain setting of the amplifier you normally use. 7. Take the inverse of the number obtained in step 6.

Date: Mon, 21 Jul 2003 10:02:12 -0500 I have a geophone with a 10 hz resonant frequency and a home made vertical with a period of about one second. Does the lower resonant frequency make the vertical less sensitive to local noise? My observations seem to back this up. There is a NAFTA rail line about 2 miles East of my house that makes a lot of low frequency noise and the geophone seems to pick it up more than the vertical. I'm using the same amplifier for each, John Lahr's circuit with an additional 2 pole filter added on at the end which I thought would pretty much cut out local noise but this doesn't seem to be the case.

Date: Sat, 23 Aug 2003 19:30:47 -0400 The lack of available manuals on seismic wave interpretation is frustrating. I recently purchased three books from Amazon which people in this group may be interested. THE SEISMIC WAVEFIELD - VOL 1 Introduction and Theoretical Development by B. L. N. Kennett - Research School of Earth Sciences - The Australian National University Published 2002 ISBN 0 521 00663 5 $36.00 THE SEISMIC WAVEFIELD = VOL II Interpretation of Seismograms on Regional and Global Scales by B. L. N. Kennett - Research School of Earth Sciences - The Australian National University Published 2002 ISBN 0 521 00665 1 $55.00 SEISMIC WAVES AND SOURCES by Ari Ben-Menahem and Sarva Jit Singh Published 1981, Revised 2000 ISBN 0 486 40461 7 $27.97 The Seismic Wavefield Vol I & II, appear to have significant amounts of information, that a non-seismologist could digest. However, both books also have a fair amount of mathematical formulas in them, but I have found that the text is laid out so I can by-pass the math, and continue with the text. This makes the books appear to me, a non-seismologist and non-mathematician, to be useful to others in my same category. Seismic Waves and Sources is VERY HEAVY in mathematics, and I will probably reserve it for another life when I have a degree in mathematics and/or physics. All of the books appears to be aimed at a graduate level seismologist, but least I was able to read the text in Seismic Wavefield, and make sense of it. If any of the "real" seismologists who are part of the group could get a look at the books, I am certain they could supply better comments that I have made. Another source for learning about seismic waves is the SEISWAVE program written by Dr. Alan L Jones PhD, at Binghamton University, Binghamton, NY. The program SEISWAVE can be downloaded from the following site: http://www.geol.binghamton.edu/faculty/jones/ Bob Hancock __________________________________________________________ Public Seismic Network Mailing List (PSN-L) Subject: looking for a book/s or web reference on iron/steel From: "Meredith Lamb" meredithlamb@.............

But I can assure you they are full of facts about metals.

These books are probably hundreds of dollars each now, so you might want to look at them in a university library before buying.

Patton" charles.r.patton@........ Date: Thu, 04 Sep 2003 20:48:59 -0700 Hi Meredith, Just to stick my nose in. Several mentions of magnetic properties were made. If you were thinking of properties in the low field region such as earth field measurements, I’ve only seen those properties in manufacturer’s spec sheets for metals/ferrites suitable for low fields. Allied Signal for Metglas for instance: http://www.metglas.com/ and Magnetic Metals for tranformer laminations and Permalloy: http://www.magmet.com/ Standard steels/irons are pretty much unsuitable at low levels as their permeability drops pretty low around zero magnetization. That’s why those applications are pretty much dominated by Metglas and Permalloy materials. For higher levels such as power transformers, you need to check with manufactures of EI laminations, such as Magnetic Metals above, who make the oriented silicon steels used in transformers. Their spec sheets will show saturation curves and energy loss curves. The ASTM books should be great for structural and chemical properties.

Date: Sat, 6 Sep 2003 01:09:19 -0700 Just wait until USArray comes on line...massive new acquisitions always seem to create a surplus of "old" but really good instruments that make their way out into the market. As for myself, work on a Santa Monica station have fallen on hard times...my apt manager who was friendly to the idea passed away due to a heart attack, and the new manager is more dubious. But it may come to fruition. We'll see. On an interesting note, a couple friends of mine are working on a joint seismic-computer science project for some new type of networking idea and a massive instrumentation deployment. The initial idea was to carpet UCLA campus, plus really wire up a single building in the med center for site and building response type things, although the deployment plan may be more flexible. The building response project was to look for non-linear signals that herald permanent deformation of the building. The networking idea had more stand alone stations that communicated with their neighbors in some fashion that made data transfer and handling more efficient. They were also doing something like this for biological sensors...pretty interesting stuff. Cheers!

The prediction, first posted on Internet web sites, has some Japanese making preparations for an imminent disaster. Although officials and scientists say no present technology can predict earthquakes, some Japanese are heeding the prediction made by Yoshio Kushida. The self-taught astronomer turned earthquake forecaster says he has developed a way to predict the timing and intensity of tremors by monitoring very high frequency radio waves. ................ __________________________________________________________ Public Seismic Network Mailing List (PSN-L) Subject: RE: Astronomer Predicts Major Quake in Japan From: "steve hammond" shammon1@............. Date: Wed, 17 Sep 2003 16:31:31 -0700 Jack Cole in the early 90's had the San Francisco bay area in a big fuss. He "monitored" the high frequency radio waves in the area by tuning his stereo radio receiver to an off channel and listening for pops and hiss. Based on his interpolations he would then alert the news media to pending major seismic events. The troubling part of this was the little girl that lived across the street from me. After not sleeping very well for several days she showed up on my front steps because she knew I knew something about earthquakes and recorded them on seismic equipment. We spent about an hour talking about earthquakes, the likelihood of being injured in one and mankind's inability to predict them.

Good for you Steve. I have been trying for years to stop the Internet tripe that comes through from Jack. In his present location, he somehow still manages to get these things out. I have yet to see but only one prediction from Jack come true and on KGO he sounded almost giddy, as though he had opened his birthday present.

Thomas you must have been around in the very fits and starts of Pinpoint....and perhaps through my mental breakdown in the 1990's. I am assuming that is what you are reff'ing. Well Pinpoint has been around since 1992 and includes many types of people from USGS seismologists, to PSN members, to those who feel they can predict through eartones and beyond. We have an open group and try not to exclude anyone....with exception and that remark I made about Jack was perhaps out of order, but I have strong feelings about the "errors" he made with his life in which have him in prison, essentially for the remainder of his life. I am sorry for for being somewhat off topic...to the group, but sensed that a personal dig like that should not go without retort.

September 22, 2000 Radio Stargazer's Key to Quakes WAVE FLUX AN EARLY WARNING SIGNAL? By REIJI YOSHIDA Staff writer Astronomer Yoshio Kushida believes he will receive forewarning should a major earthquake hit. "I am absolutely confident," he said when asked about predicting a major quake in the Tokyo metropolitan area. "(The signs of) all major earthquakes that have occurred could have been observed," Kushida said in a recent interview at his private observatory in Yamanashi Prefecture. On the night of Jan. 14, 1995, an FM radio receiver began recording an extraordinary baseline fluctuation at Kushida's Yatsugatake South Base Observatory. Kushida didn't realize it was the day that would totally change his life. He was recording radio echoes in the very-high-frequency band to observe the passage of meteors through the atmosphere. Kushida was at a loss that night, believing the machine was malfunctioning. The thickness of the baseline, usually about 1 mm, was more than 2 mm on the nights of Jan. 15, 16 and 17, leaving Kushida puzzled. But in the early morning of Jan. 17, he realized the hidden message in the signal. He turned pale when he switched on the TV. Breaking news told him that a major earthquake, measuring a magnitude of 7.2, struck Kobe and southern Hyogo Prefecture at 5:46 a.m. The earthquake led to the loss of more than 6,400 lives, destroyed 248,410 structures and left 446,485 households homeless. "I was overwhelmed by a sense of self-reproach. If only if I had studied more closely when I found (the baseline phenomenon) two years earlier," Kushida wrote in the book "Jishin Yoho-ni Idomu" ("The Challenges of Earthquake Prediction"), published Sept. 1. In 1993, after roughly examining the correlation between abnormal electric waves and earthquakes, Kushida was convinced that some fluctuating patterns in the VHF band appear several days before an earthquake. But Kushida, who had no expertise on earthquakes at the time, didn't pay much attention to the data. He thought seismologists probably already knew about the phenomenon, but in the end, that was not the case. Most seismologists think that accurate prediction of earthquakes is almost impossible, let alone early warning. But Kushida, through carefully observing the phenomena over the past five years, has continued his studies to challenge the common notion about earthquake prediction. Analyzing radio echoes from a number of FM stations across the country, Kushida believes he has found five basic wave patterns that appear several days before a major earthquake. From January 1997 to September 1999, using these patterns, Kushida predicted specific dates, strengths and locations of the focus of 36 major earthquakes measuring a magnitude of 5 or stronger. The average margin of error in the dates predicted was 1.97 days. As for location, Kushida now claims he can specify the focus of most earthquakes within a radius of 50 km. "I think (the accuracy) is practical enough," he said. Some seismologists have argued that the results could be a coincidence because earthquakes occur very often in the Japanese archipelago. But the Institute of Physical and Chemical Research, a major quasi-governmental think tank, independently examined the correlation between earthquakes and Kushida's predictions and concluded the results were not random. "(The correlation) has much significance," said Toshiyasu Nagao, director at the institute's Earthquake Prediction Research Center, which now supports Kushida's project. But what is the mechanism that causes this presaging of an earthquake in VHF radio echoes? Kushida's system was originally designed to observe meteors by catching radio echoes from a commercial FM radio station. According to Kushida's hypothesis, before an earthquake, electric charges accumulate on the Earth's surface due to the generation of numerous microcracks in magma. The charge and discharge process of a capacitor formed with the Earth's surface and the ionosphere changes density of electric plasma in the ionosphere, and the phenomenon is observed by the FM receiver. Indeed, it has been long known to scientists that some electromagnetic phenomena appear before an earthquake on the Earth's surface. In Greece, scientists have conducted studies on the prediction of earthquakes for more than 10 years based on the theory that solid matter emits an electric current just before it breaks down. The reliability of the method, however, is still a focus of debate by seismologists, although the scientists conducting the test claim the success rate is about 60 percent. Kushida recalled that seismologists' response to his method was not good when he first held a press conference and contributed to an article in a spring 1995 physics magazine. After five years of studies, many seismologists -- many of whom have little knowledge of the ionosphere or electromagnetism -- remain skeptical, or simply ignore Kushida's achievements. Kushida now only publicizes his analysis and predictions to people who have subscribed to his fax service, believing open publication of his predictions would only cause confusion or panic. "What would you do about nuclear power plants, or railway service if a major earthquake is forecast to hit? You may want to stop them, but there is no legal basis (to support such actions). There is nothing I can do," Kushida said. Kushida said he cannot take responsibility for possible results of his predictions, as they still contain a margin of error. Much more public understanding, legislation for early warning systems and more efforts to improve accuracy will be necessary before advance publication of earthquake information will be possible, he said. But interested parties can subscribe to Kushida's fax service if they sign an oath not to leak the information to other people or use it for secondary purposes. For further information, access www.yatsugatake-eorc.org/ or send a fax to the observatory at (0551) 38-4254.

We solder a 1/4" copper tube about 3" long into the steel lid of a glass jar - something like a honey jar. We feed a wick through this and half fill the jar with paraffin. The wick projects maybe 1/2" from the top of the tube. Adjust to get a suitable size of flame. We find somewhere with still air which doesn't matter getting smoked and light up. We mount good quality typing paper tight on the drum and rotate it in the smoke several inches above the flame. The close thermal contact with the drum prevents it from burning. When it is suitably black all over, we use it. When it has recorded all that we want, we VERY CAREFULLY take the sheet of paper off the drum without jarring it and then spray THE WHITE BACK SIDE OF THE PAPER with HAIR LACQUER. This penetrates through the paper and fixes the trace. When it is ~dry, we give the black front of the trace another coat of lacquer. If you try spraying the black carbon side first, you blow most of the carbon off, which defeats the object and makes a mess. It is not difficult to do and gives an extremely fine trace. Have fun!

Hi all,
After wanting a Helicorder of my very own for a long time, I've gotten ahold of
a Geotech Portacorder RV-320, which after some repairs is working.  Geotech
(geoinstr.com) very nicely sent a manual for an RV-320B for free, but the B 
seems to be the next model, about 10 years newer than mine.  Does anyone
have a manual for the older RV-320 (circa 1977)?
 
Also, I seem to have the smoked-paper version, does anyone know how horrible that
is to work with, and where might I get some appropriate paper (for relatively low $)?
 
Thanks,

Astronomer Predicts Major Earthquake for Japan, Other Experts Express Doubts
By Associated Press
posted: 03:40 pm ET
15 September 2003
TOKYO (AP) _ A Japanese researcher is causing a stir in Tokyo with a prediction based on his study of radio waves that a major destructive earthquake is highly likely to hit the city this week.
Yoshio Kushida, a well-known self-taught astronomer who runs his own observatory just outside Tokyo, published on its Internet site his prediction that a quake with a magnitude of 7 or greater was likely to strike the metropolitan area on Tuesday or Wednesday.

There was a 5.7 on the 20th 50 miles from Tokyo
http://wwwneic.cr.usgs.gov/neis/bulletin/neic_yyaa.html

Then of course, the 8.3 yesterday...  Which one did he predict? 

Its so hard to judge these things when there are years between signals for large quakes.  Maybe if there were a network of astronomers that looked for this wave flux throughout the world, it might help to answer the question as to whether there is any validity in the method. 

This same method was used in southern california by a couple of amateur earthquake people after the Northridge quake and did 'predict' the major aftershocks of that quake based on this wave flux.

I think there's some validity to the method, but don't know enough about astronomy to set up the proper equipment.
