环太平洋地区的地震活动增加，科学家监测这是美国和墨西哥太平洋沿岸的大地震前兆。
由于太平洋沿岸火环区地震活动模式更新，从一些科学家关注的潜在征兆来看，有可能未来7至10天在墨西哥 – 美国太平洋沿岸地区会有一个“特大地震”威胁。 LPAC地下室科学小组正在密切合作调查这一情况。
莫斯科的地球物理学施密特研究所（IPE），在这个周末发出一份报告，警告说，上星期六（1月21日）发生在墨西哥的6.2级地震可能是一个至少有7.5至8.3级特大地震的“潜在预兆”，可能很快会袭击墨西哥和美国太平洋沿岸地带。
IPE将恰帕斯地震和其他许多地震事件都考虑了进去，其中包括1月18日袭击墨西哥Baja 半岛的4.1级地震，和其他一些地点和时间发生的地震。人们已经注意到，高度的大气温度与恰帕斯地震及其他地震相关，有可能这种异象就是先兆。
此外，IPE的报告指出，更值得关注的是，2010年4月4日，发生在Baja California这个特殊断裂带的7.2级地震，它与墨西哥的地震带，加利福尼亚州的大断层有联系，从而激活本地区潜在的灾难性地震和火山喷发。
IPE的报告称，他们的结论已由美国宇航局中等分辨率成像光谱仪（MODIS）卫星提供的最新信息所证实。
值得注意的是地震区上空的大气升温 – 极端升温，或快速升温 ，现在已被认为是大地震前的准确预兆，例如2011年日本的大地震就是如此。311地震发生前，电离层的总电子含量，在震中地区急剧增加，在地震发生前三天达到一个最大值。
另一个警告来自Jim Berkland的预报，有可能月底在太平洋沿岸地区发生7级以上地震。

Seismic Activity Increases on the Pacific Rim; Scientists Monitor for Precursors to Major Quake on US-Mexico Pacific Coast
January 25, 2012 • 4:26AM
Amidst an apparently renewed pattern of quake activity on the Pacific Rim of Fire, a number of scientists are watching with concern for potential precursors that indicate a threat of a 'mega-quake' in the Mexico-United States Pacific border area, in the time frame of the next 7 to 10 days. The LPAC Basement science team is closely investigating this situation.
The Schmidt Institute of Physics of the Earth (IPE) in Moscow, issued a report over this past weekend, that warns that the 6.2-magnitude earthquake that struck the Chiapas region of Mexico Saturday (centered southwest off the coast, Jan. 21, 41 miles deep), is a "potential precursor" to a mega-quake of at least 7.5 to 8.3 magnitude, that could hit soon in the Mexico-U.S. Pacific border zone.
The IPE took the Chiapas quake into consideration with many other seismic events, including, for example, a Jan. 18 quake of 4.1 magnitude, which hit the Mexican Baja peninsula, and several others of certain locations and times. It has been noted that there are heightened atmospheric temperatures present associated with the Chiapas and other quakes, which would not "normally" be expected to occur.
In addition, the IPE report points out that there are grounds for more concern, given that a 7.2-magnitude earthquake hit northern Baja California on April 4, 2010, which was the first big earthquake to occur on this particular fault system since 1892, and it links Mexico's seismic zone to California's massive fault system, thus pointing to a "reawakening" of this region's potential for catastrophic seismic/volcanic occurences.
The IPE report states that their conclusions have been confirmed by their using the latest information obtained from the Moderate-Resolution Imaging Spectroradiometer (MODIS) satellite operated by NASA and available for viewing.
It is noted that heating of the atmosphere — extreme heating, or rapid heating — above earthquake zones is now believed to be an accurate predictor of major earthquake activity as was documented prior to the Great Japan Earthquake and Tsunami of 2011. Before the March 11 quake struck, the total electron content in a part of the upper atmosphere, called the ionosphere, increased dramatically over the earthquake's epicenter, reaching a maximum three days before the quake struck.
Another warning comes from forecaster Jim Berkland, about the likelihood of a 7- or greater-magnitude quake for this general Pacific-coast border area by the end of the month.
LPAC maintains a current look-up page on "Latest Earthquake Activity" (from the US Geological Survey) in the Weather section. You can see that up until about a week ago, the situation was relatively quiet. Then the pace and intensity of activity exploded, with incidents in the Aleutians, Mexico, Chile, the Caribbean, and around the Rim.
