環太平洋地區的地震活動增加，科學家監測這是美國和墨西哥太平洋沿岸的大地震前兆。
由於太平洋沿岸火環區地震活動模式更新，從一些科學家關注的潛在徵兆來看，有可能未來7至10天在墨西哥 – 美國太平洋沿岸地區會有一個「特大地震」威脅。 LPAC地下室科學小組正在密切合作調查這一情況。
莫斯科的地球物理學施密特研究所（IPE），在這個周末發出一份報告，警告說，上星期六（1月21日）發生在墨西哥的6.2級地震可能是一個至少有7.5至8.3級特大地震的「潛在預兆」，可能很快會襲擊墨西哥和美國太平洋沿岸地帶。
IPE將恰帕斯地震和其他許多地震事件都考慮了進去，其中包括1月18日襲擊墨西哥Baja 半島的4.1級地震，和其他一些地點和時間發生的地震。人們已經注意到，高度的大氣溫度與恰帕斯地震及其他地震相關，有可能這種異象就是先兆。
此外，IPE的報告指出，更值得關注的是，2010年4月4日，發生在Baja California這個特殊斷裂帶的7.2級地震，它與墨西哥的地震帶，加利福尼亞州的大斷層有聯繫，從而激活本地區潛在的災難性地震和火山噴發。
IPE的報告稱，他們的結論已由美國宇航局中等解析度成像光譜儀（MODIS）衛星提供的最新信息所證實。
值得注意的是地震區上空的大氣升溫 – 極端升溫，或快速升溫 ，現在已被認為是大地震前的準確預兆，例如2011年日本的大地震就是如此。311地震發生前，電離層的總電子含量，在震央地區急劇增加，在地震發生前三天達到一個最大值。
另一個警告來自Jim Berkland的預報，有可能月底在太平洋沿岸地區發生7級以上地震。

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.
