Article by NASA Science: "Anticipating Earthquakes"; August 2003
Quote from article: "earthquakes are synonymous with unpredictability. They strike suddenly on otherwise normal days, and despite all the
achievements of seismology, scientists still can't provide warning of an impending quake in the way that weathermen warn of approaching storms."
The above is False. Scientists can provide warning with piezoseismology.
Quote from Article: "Although earthquakes seem to strike out of the blue, the furious energy that a quake releases builds up for months and years
beforehand in the form of stresses within Earth's crust. At the moment, forecasters have no direct way of seeing these stresses or detecting when they
reach critically high levels."
The above is False. The energy that a quake builds up in hours to sometimes over a month beforehand is detectable 24 hours a day during that period
using piezseismology. Quakes don't take years to build up pressure, because the subsurface cracks usually within days to weeks because of the
pressure exerted; extremely rare over a month.
Quote from Article: "Interferometric-Synthetic Aperture Radar (InSAR). Basically, InSAR is when two radar images of a given tectonic area are
combined in a process called data fusion, and any changes in ground motion at the surface may be detected."
The above method will be used to back up piezoseismology forecasts.
Quote from article: "This technique, InSAR, is sensitive enough to detect slow ground motions as tiny as 1 mm per year. That kind of sensitivity,
combined with the landscape-wide view that satellites can offer, lets scientists see the tiny motions and contortions of land around a fault line in
more detail than ever before. By watching these motions, they can figure out where points of high strain are building up."
The above is false, 1 mm movements aren't detectable by InSAR, but InSAR will be used to back up piezoseismic detection. The InSAR European Space
Agency ERS-2 satellite shows 10cm displacement. Forecasting earthquakes from space will only be a back-up to piezoseismology.
Quote from article: "Scientists eventually should be able to use the InSAR data to infer when stresses in the Earth's crust have reached a dangerous
level, issuing a monthly "hazard assessment" for a given fault. Forecasters might report that the likelihood of having a major quake on, say, the San
Andreas fault during the coming month is 2%, or 10%, or 50%."
The above is false, a "monthly hazard assessment" would be a joke when daily reports will be broadcast worldwide using piezoseismology. The daily
hazard assessments will rely mainly on piezoseimology, and the back up of InSAR, but the data from links rupturing will pinpoint the exact date that
larger earthquakes will strike with 100% accuracy. Computer modeling of 30 years guestimates are currently a joke, similar to predicting the next
Quote from article: "One of these ideas is to look for surges in infrared (IR) radiation. Satellites equipped with IR cameras could be used to
detect these hot spots from space.
What causes rocks under pressure to emit infrared radiation? No one is certain. The frequency spectrum of the emissions shows that internal heat from
friction--e.g., rocks rubbing together--is not responsible for the radiation.
Red granite blocks under a 1,500 ton press--mimicking in some ways what happens miles below Earth's surface developed detected infrared emissions.
Furthermore, a voltage built up on the rock's surface, the cause might be electrical.
Electrical currents in rock might explain another curious observation: Scientists doing research with magnetometers just before major earthquakes have
serendipitously recorded tiny, slow fluctuations in Earth's magnetic field. One example happened during the Loma-Prieta earthquake that devastated San
Francisco in 1989. Almost 2 weeks before the quake, readings of low-frequency magnetic signals (0.01-0.02 Hz) jumped up to 20 times above normal
levels, and then spiked even higher the day of the quake.
The cause of these signals is unknown; a piezo-magnetic effect triggered by pressure applied to certain kinds of rocks. Both the infrared and
magnetic methods of quake detection are controversial."
The last quote is interesting.
