6000-Year-Old Human Skull Found In Papua New Guinea Likely Belongs To World's Oldest Tsunami Victim In 1929, the 6000-year-old human skull was found in a site at Papua New Guinea. New research analysis has now revealed that the ancient skull likely belongs to the oldest tsunami victim in the world, and the catasthrophic event killed that person. Professor James Goff, the first author of the study and a UNSW Sydney scientist, says that the site where the Aitape Skull was found was once covered…

Lassen Volcanic’s geology is very interesting. The terrain has been influenced from many different natural occurrences from 25,000 to 18,000 years ago. Referring back to the May 22, 1915 eruption, the active volcano created a great deal of devastation and depressions; known as the Devastated Area. The devastation caused has an area of three square miles. Volcanoes are common at Lassen. In fact, Lassen is home to all four types of volcanoes, which are shield, cinder cone, plug dome, and…

Precambrian time covers the tremendous greater part of the Earth's history, beginning with the planet's creation around 4.5 billion years prior and finishing with the development of complex, multi celled life-shapes very nearly four billion years after the fact. The Precambrian is the most punctual of the geologic ages, which are set apart by various layers of sedimentary rock. Set down over a huge number of years, these stone layers contain a lasting record of the Earth's past, including the…

The earthquake of 1906 was a horribly destructive and stunning event. It was described by people that were there, some of them described it in books. One of these books in the novel Dragonwings, where a character named Moonshadow feels the ground twist and turn between his feet. There are also articles found that explain the natural phenomena of the terrible earthquake that occurred on April 18, 1906. The name of one remarkable article that gives many facts is called “Web Resource”. Though…

Farallon plate. This formed low angle faults and grabens. These geologic features can be found throughout the southern part of the Rio Grande rift. The second rifting phase occurred approximately 20 million years ago, and was triggered by the disappearance of the Farallon plate in the subduction zone (Baldridge, 1989). During this time frame the Farallon plate had completely subducted into the North American plate and the part of the Pacific plate started touching North American plate in a…

2.5. ANTIOXIDANT STATUS 2.5.1. TLC - Semi Quantitative DPPH Assay 0.2 % DPPH solution in methanol was prepared and kept in the fridge for further use. The grid space was marked with 1.0 cm2 space on an aluminum based TLC sheet (Merck silica gel 60F254) and a stock solution of all the extracts together with the standard were prepared in methanol. A series of dilutions of the stock together with the standard were prepared ranging from 400 µL to 0.01µL for the last dilution. The grid on the TLC…

Wash hands and spray down or wipe your work are with disinfectant. Dry off with paper towels. Label the bottom of your agar plate (petri dish) as diagrammed in your Experimental Design (note: the bottom of the plate contains the nutrient agar, which looks like a clear/beige gelatinous material). Determine your two sources of collection for bacteria specimens. When you have decided, write them in tour data table on your…

The northern coast of Sumbawa Indonesia that in April 1815 exploded in the largest eruption in recorded history. It is now 2,851meters (9,354 feet) high, having lost much of its top in the 1815 eruption. The volcano remains active; smaller eruptions took place in 1880 and 1967, and episodes of increased seismic activity occurred in 2011, 2012, and 2013. Tambora’s catastrophic eruption began on April 5, 1815,. A shattering blast blew the mountains apart on the evening of April 10. The blast…

San Francisco – The Bay Area was shaken to its core Monday morning when an earthquake struck around 7:12 a.m. with a preliminary magnitude of 6.4. One San Francisco resident was awakened that morning not by the quake, but by a chunk of cement flying through his kitchen. Michael Beamer said he was eating breakfast before the earthquake began, and when it did he ducked and covered under his kitchen table. “I was eating my breakfast and the room started rolling. I dove under the table just as I…

The collapse of the Cypress Street Viaduct in 1989 was a disaster caused by an earthquake. On October 17, 1989 an earth quake occurred around the Santa Cruz bay area. The Cypress Street Viaduct was the first double-decker viaduct in California and it was made in 1955 – 1957 and it cost 100 million dollars. On October 17, 1989, the southern portion of the structure collapsed during the 1989 Loma Prieta Earthquake, due to ground movement and structural flaws. When in use, the upper and lower tier…
