A third significant pattern in the ELF (Extremely Low Frequency) to VLF (Very Low Frequency) portion of the electromagnetic spectrum has now been observed and recorded. The pattern is one of a series of higher frequencies followed by a series of lower frequencies, with a period of approximately 60 - 100 secs for each group of pulses. There is no known local or residential origin for these signals, and they are to be regarded at the same level of interest as the ELF signals that have now been recorded on multiple occasions.

The current VLF observations are significant in that they are not continuously occurring; three segments of approximately 15 minutes duration each were observed on Mar 03 2003. The switching and pulse nature of the observations abruptly ceases and starts, as is shown on the graph which follows on this page. There is no gradual transition between the different phases, and the variation in frequencies appears to be the direct result of a constructed modulation system.

It is also significant to report that a developed electronic digital logging magnetometer operating at this site recorded anomalous magnetic readings during this same time period. More information on the magnetometer will be reported at a later date, however, the readings were some of the more unusual that have been observed in over a month of recording time.

It is therefore quite possible that the signal structure shown on these pages will be more difficult to capture than the ELF patterns (4Hz multiples) that have been reported on a continuous basis. The viewing of the frequency pattern shown on this page can be regarded as the result of fortuitous and unusual circumstances, and it may require greater patience to replicate these results. This is due to the fact that this pattern does not appear to be a continuous process by any means. Unusual readings on the magnetometer may serve as a useful indicator as to when such pulses are present. Three such periods, each approximately 15 minutes long, occurred on today's date simultaneously with the unusual magnetometer readings.

This graph shows an initial interval of approx. 14 minutes of alternating pulsed frequencies. This interval is followed by approximately 16 minutes of no pulsed alternating activity.

Pulsing then begins again for approximately 10 minutes and then again ceases. The individual pulse sections last approximately 60 -100 seconds each. The observations were collected with the use of the ELF meter that has been described elsewhere on this site. An external wire antenna approximately 5 feet long was used on this occasion. The potentiometers within that circuit allow the sensitivity or gain of the circuit to be adjusted. The second potentiometer can be regarded as a coarse tuner, and the first potentiometer as a fine tuner. Lower settings on both potentiometers permit the 4Hz multiple cycle detection (the lower multiples within a residential environment), higher settings permit the detection of the 60Hz power signal (if required) and still higher settings permit detections within the VLF portion of the spectrum. Many variable combinations of sensitivity exist. The circuit was set for approximately 1kHz at the time of these readings. It is the variations within the kilohertz portion of the spectrum that are deserving of attention at this stage of research; the magnitude is not given special significance at this time. Until the nature of the pulses shown above is determined, it may be that these variations are detectable across a fairly broad range of frequencies.

Indications are that this pattern of pulses in the VLF range may also be observable at a more distant location. This will be reported at a later time if and when additional data becomes available.

It is hoped that other citizens will begin the process of circuit construction ( and modification and improvement) to examine the findings that have been reported on this site during the last few months. It is in the interest of the general health of the population that such testing occur.

3-axis wide-band ULF/ELF induction-type magnetic sensors have been working in Seikoshi, Izu Japan since May 1999. During 18-month observation period, we have a significant increase in Hz/Hx starting about 20 days before a series of large seismic events (M>6) near Izu islands (source-observer distance is less than 100km). This anomaly is seen mainly in the frequency band ranging from 0.01Hz to 0.022Hz in good coincidence with the previous results from other large earthquakes and is only the largest value during the above-mentioned observation period, suggesting a clear precursory signal of large seismic activities near the observation site.

Large-amplitude ULF magnetic fluctuations before Loma Prieta earthquake (17 Oct 1989, Ms 7.1) were observed by a magnetic coil [2]. ULF magnetic precursory signals were identified by using rather sophisticated methods like polarization analysis [6] and like the concept of SOC (Self-organized Criticality) [5] for Guam earthquake (8 Aug. 1993, Ms=8.0). ULF anomalies in association with the above-mentioned two large earthquakes were detected rather close to the epicenter; 7km for Loma Prieta and 60km for Guam. On the contrary, no significant enhancement in ULF amplitude was found in the case of Northredge earthquake of 17 January 1994, Ms=6.7 [3] because of large epicenter-observer distances from the two stations (81km and 266km). But [1] have found a significant ULF activity before the earthquake on a magnetic antenna with different orientation. An increase in the power spectrum (f>10Hz) well above the background noise in ULF/ELF frequency range for some earthquakes was detected after the main shock only 9.5km from the epicenter in 1994 by [7]. Above-mentioned results imply the limitation of the detection of ULF precursory signals as functions of magnitude and source-observer distance. Based on the previous works, our most important purpose is to detect ULF emissions in relation with any earthquakes in the Kanto area including Izu islands. And our final goal is to model the source of the emission and then derive the quantitative information and understand the generation mechanism.

3-axis induction type magnetic receiving system was installed in Seikoshi, Izu peninsula. We have a continuous record of ULF signal in the frequency ranging from 0.1mHz to 4Hz with a sampling frequency of 10Hz from all three orthogonal sensors (two horizontal components, Hx and Hy, and the vertical component Hz). Whereas one data channel (Hx) is allocated to make synoptic (10% duty cycle) measurement for ELF frequency range (from 1Hz to 200Hz) with 500Hz sampling rate. In this paper we analyzed only 10Hz sampling data.

In this paper we performed the so-called polarization analysis. This method was hinted by the experimental results by [8] and the theoretical prediction by [9] and worked effectively to reveal the precursory signal of Guam earthquake [6] and Biak earthquake [4]. This method can distinguish between space plasma waves represented mainly by the geomagnetic pulsation (predominant in horizontal component) and seismo-magnetic emissions (having the vertical component rather than the horizontal ones when the observation site is not exactly in the epicenter).

The ULF/ELF measurement started recently in Seikoshi, Izu, Japan successfully detected the precursory anomalies for large earthquake (M>6) occurred near Izu Is. (source observer distance < 100km). These anomalies are represented by a large enhancement of a polarization factor Hz/Hx and most clearly seen in the frequency band ranging from 0.01Hz to 0.022Hz. This enhancement starts about 20days before the seismic event and reaches maximum about 3 days before the seismic shock. Besides, it has the largest value (ex. At least 2 times larger than usual anomalous Hz/Hx) during 18-month period suggesting rather clearly the correlation between the large seismic event and ULF anomalies. Whereas we do not see any clear anomalies in relation with small seismic events M <4 suggesting the detection threshold of this method under the electromagnetic environment of the observation site. Furthermore, we have obtained the similar results for Hz/Hy and Hz/Hg Hg=sqrt(Hx*Hx+Hy*Hy) with less significant enhancement in the polarization.

  1. In my observation some ULF bursts to tend to precede large quakes, and follow after bursts of energy from the sun, in turn related to the Sun-Jupiter relationship. In relation to your proposals, bursts of energy from the sun need mapping against your data so as discover if the ULF bursts you record, correlate, or form anomalously to the sporadic bursts from the sun.
