Like tiny Lilliputians scurrying around Gulliver, researchers in submersibles have been probing and measuring Loihi since 1987. The growing seamount is offering scientists new insights into the evolution of volcanoes, the evolution of life and perhaps even the evolution of the Earth itself. Research on the nature of Loihi has already revised ideas about the workings of the planet's largest known hot spot. Recent…

Undara Lava tubes consist of a lava field remaining from a massive volcanic eruption of Mt Undara which occurred 190,000 years ago. During the Cenozoic, there was wide spread igneous activity in Eastern Australia. Volcanism commenced in the late Cretaceous (approximately 70 Ma) and continued through the Cenozoic. The cenozoic is the current geological era. It began 66 million years ago and continues today. About 23.3 km³ of lava flowed from the Mt Undara volcano at an estimated rate of 1000 m³ a second. This lava flowed about over 160km to the north west and 90km to the north. The tubes were formed when these rivers of lava crusted over on the outside forming an insulated tube for the rest of the lava to flow along. Eventually the liquid lava…
The Amazon basin in South America, vegetated by tropical rainforest, lies within the equatorial climate zone and covers an area of some 8,235,430 km 2 mainly in Brazil. The Amazon River flows through the basin from its source high in the Andes towards its mouth in the Atlantic Ocean, and is the largest single source of freshwater runoff on Earth, representing 15-20% of global river discharge. At present the amazon rainforest acts as a carbon sink. It absorbs around 35% of the world’s annual carbon dioxide emissions and produces more than 20% of the world’s oxygen. It contains the greatest biodiversity on Earth, providing a habitat for more than half the worlds estimated 10 million species of plants animals and insects.…

Archaeological data suggests that the date 2200 B.C can divide the occurrence of square ended seals from rectangular ones. Assumedly, any sampled sites with the presence of square ended seals existed prior to 2200 B.C, while the rest of the sampled sites with rectangular seals existed after this particular date. Consequently, we may indicate sites dated prior to or up to 2200 B.C, and sites “B”, “D”, Garam Masala (GM), and Phul-Ghobi Lower (PGL) fits the equation since all of these sampled sites had square seals. On the other hand, rectangular seals were only found in four sites of “B”, “C”, “E”, Tiltandula (T), and Phul-Ghobi Upper (PGU). In particular, site “B” has both of the square and rectangular seals each that may suggests that the site existed prior to 2200 B.C and have the possibility to continue for some time after. In addition, Lower Phul-Ghobi (LPG) and Upper Phul-Ghobi (UPG) were radiocarbon dated back to 2450 ± 70 BC and 2100 ± 50 B.C respectively.…
The Yellowstone volcano has been a growing concern for many Americans over the years. Especially after the eruption of the Mount St. Helen's volcano in the 80's. Rumors of a catastrophic explosion have caught the attention of everyone from the media to newspapers who try to sell the fear of an imminent explosion and the extreme damage that could possibly happen. However, the truth is just the opposite. In actuality, these fears are almost always unfounded, and usually arise from the the rumors of the damage it may cause. Further investigation of the current status of this supervolcano in fact reveals the true nature of this "massive threat."…
There are several reasons that influence volcanic hazards, these include the viscosity of the magma, proximity to population centres, materials that are ejected from the volcano, the magnitude of the eruption and the plate margin that the volcano rests upon.…
Visitors can see the remains of the Pompeii citizens in the ruins of an ancient volcano eruption. There have been many volcanic eruptions throughout history. When a volcano erupts, it destroys everything near by. The eruption of Mount Vesuvius devastated and destroyed Pompeii. Understanding volcano eruptions can help scientists predict them, unlike in Pompeii an ancient volcanic disaster .…
Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land, the creation of valuable natural minerals and ores, and the enhancement of countries’ tourism potential.…
