NASA设计大赛将搜寻预测地震的电磁脉冲
目前，美国宇航局举办为期两周的“探索地震”的挑战大赛，旨在征求搜寻预测地震的电磁脉冲信号最佳方案，并提供25000美元的奖金。
腾讯太空讯 据国外媒体报道，在地震发生期间，地球磁场会出现一些奇特的现象，有证据表明电磁脉冲(EMPs)能够从地壳喷射，在发生地震之前电磁脉冲会变得更强、发生频率更高。目前，美国宇航局设立一项最新挑战项目，寻找支持电磁脉冲预警地震的有效方法，从而更准确地预测地震灾难。
美国宇航局为期两周的“探索地震”的挑战大赛，参赛者设计最新软件代码或者算法，搜寻梳理电磁脉冲中的“地震数据信号”。一些研究人员认为，源于震中附近的电磁脉冲，是预兆其它地震发生的可靠信号。
美国宇航局程序师克雷格-多普森(Craig Dobson)说：“研制一种从无数自然和人为源声音中分离地震诱导电磁脉冲的可靠方法是至关重要的，同时也具有很大挑战性。我们期待在此项竞赛中看到一些创新理念，更加深入了解这种对人类文明带来灾难性破坏的自然现象。”
参赛者需要提供从过去地震事件中传感器获得的3个月电磁信号数据，其中也可能包含非地震源的控制数据。他们将在两个星期之内设计软件代码，提供提取相应的电磁脉冲信号或者识别潜在的地震前兆信号。
此次挑战大赛最终获胜者将得到25000美元的奖金。据悉，科学家对电磁脉冲与地震之间的关联性已质疑多年时间，研究人员已开始研究一些轻微和大型地震之前几周震中附近地球释放超低频电磁脉冲的形成原因，一种理论认为，地壳中产生裂缝的岩石会制造带电脉冲，传输至地面，并对当地磁场构成很小的变化。然而，还存在着许多自然和人造电磁“噪音源”，例如：闪电、太阳风暴、通勤列车等，它们可以模拟或者掩盖与地震相关的电磁脉冲信号。
这项设计挑战大赛意义重大，虽然具有一定的难度和挑战性，但是如果能够精准地预测地震发生前兆，将挽救许多人类生命。（悠悠/编译） 以下是NASA的官网发布的信息及联系方式，特转贴在此。

NASA Hosts ‘Quest for Quakes’ Data Challenge

A new NASA challenge is looking for evidence to support a theory that electromagnetic pulses (EMP) may precede an earthquake, potentially offering a warning to those in the quake’s path.
The “Quest for Quakes” two-week algorithm challenge seeks to develop new software codes or algorithms to search through data and identify electromagnetic pulses that may precede an earthquake. Some researchers have speculated such pulses originating from the ground near earthquake epicenters could signal the onset of some quakes.
“Developing a reliable approach that can separate potential earthquake-induced electromagnetic pulses from the myriad of natural and anthropogenic sources has been a significant challenge,” said Craig Dobson, program scientist at NASA Headquarters in Washington. “We look forward to seeing the innovative ideas from this competition and learning more about this controversial phenomenon.”
The challenge opened for registration on Tuesday. Competitors will be able to submit entries from Monday, July 27 at 1 p.m. ET through Monday, Aug. 9 at 1 p.m. ET.
Contestants will be provided with electromagnetic signal data collected over three-month periods from multiple sensors in the proximity of past earthquakes. Control data with no earthquakes also will be included. Coders will have two weeks to develop a new approach to extract the signals and identify potential earthquake precursors. The individuals or teams developing winning approaches will share a $25,000 prize.
The connection between electromagnetic pulses and earthquakes has been debated for years. Researchers have been looking into the causes of distinct ultra-low frequency EMPs emanating from the ground near earthquake epicenters in the weeks leading up to some moderate and large events.
One theory suggests that fracturing rock in the Earth’s crust creates an electrical charge pulse that travels to the land surface and manifests itself as a small change in the local magnetic field. However, there are a number of natural and human-made electromagnetic ‘noise’ sources, such as lightning, solar storms, commuter trains, and traffic, that can mask or mimic EMPs and could be associated with earthquakes.
The data for this competition was provided by the QuakeFinder group, a humanitarian research and development project by Stellar Solutions, Inc., Palo Alto, California. QuakeFinder has 125 sensors in California and 40 sensor suites around the world. These ultra-low frequency magnetometers collect and transmit high-rate data to Stellar Solutions’ data center for management and evaluation. Over 65 terabytes of data have been collected from sensors along the San Andreas fault and other faults in California, Chile, Peru, Greece, Indonesia and Taiwan.
Amazon Web Services (AWS) has contributed a research grant for approximately three terabytes of high-frequency magnetometer data and computational resources to be used by contestants.
“The “Quest for Quakes” contest is a great example of how the AWS Cloud infrastructure is ideal for many different research and scientific workloads,” said Jamie Kinney, AWS senior manager for scientific computing. “We are looking forward to the innovative applications that contestants develop to address this real-world challenge and may also save lives."
The ”Quest for Quakes” challenge is managed by the NASA Tournament Lab established by NASA and the Crowd Innovation Laboratory at Harvard University in 2010 to create the most innovative, efficient and optimal solutions for specific, real-world challenges being faced by NASA researchers. The lab is using Appirio’s topcoder.com crowdsourcing service to host the challenge, which is open to the public and the more than 815,000 members of the topcoder community.
