Still, with evidence mounting that the signals might be real, some scientists are calling on the federal government to develop a network of electromagnetic sensors to detect such signals before quakes. Even skeptics agree more detection is necessary.
"We need a much more comprehensive (electromagnetism-monitoring) network," Johnston said.
But Bill Ellsworth, a prominent Geological Survey geophysicist, said that in the absence of an infinite amount of federal funding, first priority should go to the development of more seismic-detection networks that -- unlike earthquake alarms -- are based on well-understood physical principles.
Research team leader Dr Huilin Xing said the AGU's last-minute inclusion of the UQ research in an added special session entitled “The 2007 Sumatra Seismic Sequence”, reflected the significance of the work.
The predictions were made using advanced computer simulation software developed as part of a research program under Dr Xing, with researchers utilising the ESSCC's Altix supercomputer – one of the fastest in Australia – to model scenarios and determine the highest risk areas.
Under the program, the fleet of natural-resources satellites must include meteorological observation craft (three Meteors and one Elektra in a geostationary orbit); Earth monitoring craft (two Kanopus-V and two Resurs craft); and two dual-capable craft (radar-carrying Arkons).
The A$30 million Lightning mission aims to put two satellites about 400 kilometres above the earth with the capacity to change the height of orbit by firing thrusters.
"That would be a world first," Cairns says. "Lightning would open the door to Australian remote sensing capability and having instruments of our own that we control."
He says Lightning will track changes in the atmosphere and ionosphere as well as play a role in climate change and remote sensing research.
地震に先行する電磁気的異常についても古くから研究されている。前兆現象としては前述の前兆すべりが最有力候補であるとしても、特に内陸の活断層においては前兆すべりが非常に小さく、その歪み変化を直接捉えることは絶望的に困難である。そこで、そのような小さな変化が電磁気的現象によって捉えられればこんなに嬉しいことはない。電磁気学的直前予知の研究の必要性は学士会会報第865号で上田先生が力説しているが、まさにその通りである。ただ、電磁気学的信号といっても、地震現象は力学的現象であり、力学的現象から電磁気学的現象に変換されて地表にまで運ばれる必要がある。そのようなしくみについてはいくつかの有力なモデルが提示されているが、まだ検証されていない。

地震の前兆探しのような、狭い予知研究に偏っていたとは思っていません。ただ、予知を言わないと予算が付かないので、「予知に役立つ」といって予算をもらっていた側面はあり、反省しなければならないと思います。言っていることと、やっていることに乖離（かいり）がある、予知を便法に使った、と批判される面は確かにあったかもしれません。 1995年に阪神大震災が起きて、予知という言葉が魔女狩りのようにたたかれ、政府の地震予知研究推進本部も地震調査研究推進本部に変わりました。私の当時の肩書きも地震予知研究センター長から地震調査研究センター長に変わりました。ただ、側杖を食って火山噴火予知研究室まで火山噴火調査研究室と変えられたのは、やりすぎではないかと思いました。噴火は予知できると思っていましたから。

This years Team Projects included a space traffic management plan (if our satellites are about to crash into each other who has to move?), a lunar archive of historical and biological materials (what would you need to know and what would you need to have on hand to restart society if any part of it was lost?), a report on the future of on-orbit servicing, and a report on using satellites to monitor and respond to earthquakes. (Wired)
Avdeev's perspective came from three flights aboard Mir, the Soviet space station in orbit for 15 years before being abandoned in March 2001. Cosmonauts were able to monitor volcanoes and work on perfecting earthquake prediction techniques by making observations from above.

More than 10 Neva-based projects have been selected and screened. The mini-satellites can be launched by any existing launch vehicles, depending on their power, either singly or in clusters, but the emphasis will be on combined air and space launches. [和訳]
地殻化学実験施設は，昭和53年（1978年）4月に理学部の附属施設として新設されたので，来年で30周年を迎える。「地殻化学」という名称は，口あたりがよく憶えやすい名前であるが，理化学辞典や地学事典に項目として載っている学問分野ではなく，対応する英語名もない。あえて言えば“Chemistry of crust”である。また，当施設の英語名称は“Laboratory for Earthquake Chemistry”であるが，これを日本語に直訳した「地震化学」とも異なる。このような名称が付けられるに至った背景には，創設当時の関係者の苦労が込められている。
"People are looking for the silver bullet," said the Southern California Earthquake Center's Jordan, who is also a seismology professor at the University of Southern California. "It seems logical that something would happen before an earthquake. [But] there is no signal that is diagnostic."
Others still hold out hope. Bleier of QuakeFinder prefers to talk about "forecasting" rather than "prediction" - but regardless of which term you use, he believes the feat will be possible someday.
On KA "Resurs-DK" is conducted also the experiment of the Moscow physical engineering institute (state university) "Arina". Its purpose: a study of the prognostic characteristics of the opened by MEPhI seismomagnitosfernogo phenomenon - it is splash the high-energy charged particles in the near-earth outer space of seismic nature, which come out as foreshocks. Data on the study of the characteristics of those discovered it is splash particles already today they made it possible to make conclusions about the special features of the physical processes of interaction of the high-energy particles of radiation belts with the excited geomagnetic tube, which is rested on the center of the prepared earthquake.

Its successor Compass-3 is being launched in December 2008, but new
apparatus from Uppsala is planned to reach outer space as early as this year.
A Mexican-Russian nanosatellite for earthquake research will contain three
Swedish instruments: one from the Royal Institute of Technology in Stockholm
and two from Uppsala, which bears overall responsibility for the instrument.
In addition to a newly developed radio receiver, a socalled Langmuir probe will
be measuring electron density in space plasma.
“It’s a classic Uppsala instrument for which we are the global leader,” Jan Bergman concludes.
One of actively developed directions of thematic processing space data in NTsOMZ is reception of thematic products with signs of preparation of earthquakes. One of last development of a department of thematic processing space data is offered to your attention.
On site NTS OMZ the section, devoted to forecasting and space monitoring of precursors of earthquakes prepares for the publication. At the moment the fragment of presentation ≪Sun-earth activity and the forecast of earthquakes≫ to the report presented on Readings of memory of Alexander Leonidovicha Chizhevsky on March, 29th, 2007 in the Moscow State University by it is offered to attention of experts.

It's too soon to say whether Freund's theories will be upheld or refuted, but the balance of expert opinion and evidence clearly is beginning to shift in his favor. Bryant and others, in work not yet published, have compiled hundreds of anomalous infrared events that are sharply aligned with faults and preceded quakes.
Close cooperation is expected in the early forecasting of earthquakes from space. The Ukrainian program, "Ionosats," is intended to study the ionosphere's responses to all kinds of seismic effects. In its philosophy it is close to the Russian Kaompas, Vulkan and Arina projects.

6. In many places in our planet, we experience severe earthquakes resulting in loss of life, loss of wealth and in some cases it destroys the decades of progress made by the country and its valuable civilizational heritage. India has earthquake problems periodically in certain regions. During my recent visit abroad, I found serious research in Iceland, Ukraine and Russia by young scientists. It is essential India has to work on mission mode research for forecast the earthquake using multiple parameters using precursors such as pre-shock conditions, electromagnetic phenomena prior to final rupture and atmospheric and ionospheric anomalies.
A new field called seismo-electromagnetics is currently making waves among Filipino and Japanese earth scientists who committed to pursue this new knowledge for gainful use. [image]
