Book Description
Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.

Book Description
How small is mankind to the earth? The average depth at the equator is about 6,378 kilometers, and humans′ general living space is about 10 meters below and 90 meters above, totaling a space within about 100 meters. Although humans have traveled all over the world, which even includes Mariana Trench, the deepest part of the ocean (11.000m), and the moon, which is 384,400km away, but when it comes to the depths of the earth, humans have only explored a deepest of 12,263m. Compared to the radius of the earth (6378,000m), humans have only explored 0.19% of the earth! Are there other unknown creatures living under the ground? Is the underground full of gold and gems? Many mysteries are solved little by little in the excavation plan that humans are working hard to carry out. Now, follow our lead to explore this mysterious realm! To begin, let′s start from 2 meters underground...

Book Description
Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on Earth. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows which altered whole ecosystems. Every day we walk on an earth filled with an underground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters. Filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.
