If you see equipment of American gas researching company in your place, earthquakes are included. Those Yanks have gone mad of their shale gas. They've already turned inside out their North American Continent. And now it is able to say by ruins what countries they've already visited. I'm learning to be geologist. And I'm writing graduation dissertation about seismic danger of shale gas production. The life of a shale gas drill hole is from 7 to 10 years. No wonder that Yanks are seeking for shale gas sources all over the world. It is very easy following American trace in Italy, Great Britain, Turkey, Panama... Now Philippines were added into this list. Yanks promised them the moon. And naïve autochthons let US resource companies making researches in South China Sea. By the way this isn't even Philippine territory at all. But clever Chinese or Vietnam wouldn't allow Yanks get anywhere near it. So USA pretended that they don't remember anything about such twists and turns. And flattered Filipinos let them doing what they want. Now they are paying for it by constant shake-ups. This region has been always of increased seismic activity. And Yanks have just begun working in. It would be no wonder if there would be no Philippines at all within a year. And USA wouldn't mind. They are giving a raspberry on everyone in the world. Why Philippines should be exception?
