Only occasionally will a larger magnitude earthquake strike and cause damage to the region.

As people fled from the increasingly barren and devastated Fertile Crescent, Bronze Age settlements began growing on the Mediterranean’s east end. During the Babylonian reign of , wood was extremely scarce and his agents were charged with finding more wood. Under Hammurabi, illegal woodcutting was a . The search for wood extended past deforested Lebanon to the Mediterranean’s periphery, and Crete’s inhabitants began to trade wood for luxury items with Near East civilizations. The nearly extinct Near East cedar was reserved for palaces and temples in Mesopotamia, but on Crete, cedar was so abundant that it was used for tool handles and had other mundane purposes. Trade with the Near East quickly boosted Crete from a forested hinterland, isolated in the eastern Mediterranean, into a powerful state, at least while its forests lasted. In early , wood was used lavishly. The Minoan success influenced the nearby Peloponnesian peninsula, and Mycenaean civilization began about 1600 BCE. Minoans developed the still-undeciphered script. Mycenaean Greeks developed , which has been largely decoded and ; it is likely that Linear A also was only accounting. About 1700 BCE, the Minoan palaces were destroyed, probably by an earthquake. The palaces were rebuilt on a grand scale, and settlements expanded in the Minoan golden age, which lasted about three centuries. Then a swift decline collapsed the Minoan civilization by 1200 BCE. Mycenaeans then annexed the island.

As scientists have been putting this picture together, one irony is that Cro-Magnons had black skin, and Neanderthals might have had light hair and eyes, as an adaptation to the cold climates that they lived in, as with Europeans today. It turns the racist aspect of on its head, and has been noted in some scientific corners. For the remainder of this essay, as all other human species were extinct but for the “hobbits” by 30 kya, the word “human” will refer to behaviorally modern .

In the historical period, when technologically advanced humans encountered less advanced ones, there was cultural and genetic interchange, but in the end, the technologically advanced peoples . If any place on Earth could have been used as an illustration of the climate change hypothesis for the megafauna extinctions, ice age Europe would have been it. Ice sheets extended so far southward that Neanderthals lived in relatively few refugia, but I highly doubt that it caused their extinction. Neanderthals lived for at least 300,000 years and survived radical climate changes just fine. Human-agency skeptics have invoked unusually violent climate changes that coincidentally appeared when behaviorally advanced humans arrived around the world, but that seems to be grasping at straws. Again, there is nothing climatically unique about the past 60,000 years, , so invoking climate-change effects for humans and animals that weathered the ice age’s vagaries just fine seems to be a huge conjecture that may be politically motivated. Human-agency skeptics have crafted different kinds of climate explanations for each major extinction, such as drying in Australia, getting colder and dryer in Europe, or getting when most of the extinctions happened. At , climate was a proximate cause, not the ultimate one. The ultimate one was people virtually every time.

This massive and destructive earthquake occurred on January 12, 2010 at approximately 4:53 p.m.

Athens began a war with the Spartan-led Peloponnesian peoples that lasted from 431 BCE to 404 BCE. The war was largely another naval one, and fighting over forest access was the prominent dynamic; Spartans invaded and leveled its trees, turning it into a barren wasteland. In the aftermath of Attica’s destruction, a disease broke out and accompanied Attica’s refugees to an increasingly overcrowded Athens and initiated one of the world’s first recorded epidemics, today called the . Historians and scientists have as to the disease’s identity.

In 508 BCE, Athens entered its classical period, which lasted for nearly two centuries. In those two centuries, so much was invented by Greek philosophers and proto-scientists that it has been studied by scholars for thousands of years. One provocative question that scholars have posed is why the Industrial Revolution did not begin with the Greeks. The answer seems to be along the lines of Classic Greeks not having the social organization or sufficient history of technological innovation before wars and environmental destruction ended the Greek experiment. The achievements of Greece over the millennium of their intellectual fecundity are far too many to explore in this essay, but briefly, the Greeks invented: , , , the , a monetized economy, thought, such as , while developing other branches to unprecedented sophistication, and , which included the idea that . Long after the Classic Greek period was over, Hellenic intellectuals and inventors kept making innovations that had major impacts on later civilizations, such as Heron of Alexandria (or some other Greeks) inventing the and .

FREE Essay on Earthquakes and Its Dreadful Effects

The two types of hazards I will be outlining the causes for are hurricanes and earthquakes.

Certain disasters stem from many small problems conspiring to cause one very large problem. For want of a nail, the war was lost; for fifteen independently insignificant errors, the jetliner was lost. Subduction-zone earthquakes operate on the opposite principle: one enormous problem causes many other enormous problems. The shaking from the Cascadia quake will set off landslides throughout the region—up to thirty thousand of them in Seattle alone, the city’s emergency-management office estimates. It will also induce a process called liquefaction, whereby seemingly solid ground starts behaving like a liquid, to the detriment of anything on top of it. Fifteen per cent of Seattle is built on liquefiable land, including seventeen day-care centers and the homes of some thirty-four thousand five hundred people. So is Oregon’s critical energy-infrastructure hub, a six-mile stretch of Portland through which flows ninety per cent of the state’s liquid fuel and which houses everything from electrical substations to natural-gas terminals. Together, the sloshing, sliding, and shaking will trigger fires, flooding, pipe failures, dam breaches, and hazardous-material spills. Any one of these second-order disasters could swamp the original earthquake in terms of cost, damage, or casualties—and one of them definitely will. Four to six minutes after the dogs start barking, the shaking will subside. For another few minutes, the region, upended, will continue to fall apart on its own. Then the wave will arrive, and the real destruction will begin.

To see the full scale of the devastation when that tsunami recedes, you would need to be in the international space station. The inundation zone will be scoured of structures from California to Canada. The earthquake will have wrought its worst havoc west of the Cascades but caused damage as far away as Sacramento, California—as distant from the worst-hit areas as Fort Wayne, Indiana, is from New York. FEMA expects to coördinate search-and-rescue operations across a hundred thousand square miles and in the waters off four hundred and fifty-three miles of coastline. As for casualties: the figures I cited earlier—twenty-seven thousand injured, almost thirteen thousand dead—are based on the agency’s official planning scenario, which has the earthquake striking at 9:41 A.M. on February 6th. If, instead, it strikes in the summer, when the beaches are full, those numbers could be off by a horrifying margin.

This problem is bidirectional. The Cascadia subduction zone remained hidden from us for so long because we could not see deep enough into the past. It poses a danger to us today because we have not thought deeply enough about the future. That is no longer a problem of information; we now understand very well what the Cascadia fault line will someday do. Nor is it a problem of imagination. If you are so inclined, you can watch an earthquake destroy much of the West Coast this summer in Brad Peyton’s “San Andreas,” while, in neighboring theatres, the world threatens to succumb to Armageddon by other means: viruses, robots, resource scarcity, zombies, aliens, plague. As those movies attest, we excel at imagining future scenarios, including awful ones. But such apocalyptic visions are a form of escapism, not a moral summons, and still less a plan of action. Where we stumble is in conjuring up grim futures in a way that helps to avert them.

Research Paper On The Destruction Of Earthquakes Essay

Across the region, other, larger structures will also start to fail. Until 1974, the state of Oregon had no seismic code, and few places in the Pacific Northwest had one appropriate to a magnitude-9.0 earthquake until 1994. The vast majority of buildings in the region were constructed before then. Ian Madin, who directs the Oregon Department of Geology and Mineral Industries (DOGAMI), estimates that seventy-five per cent of all structures in the state are not designed to withstand a major Cascadia quake. FEMA calculates that, across the region, something on the order of a million buildings—more than three thousand of them schools—will collapse or be compromised in the earthquake. So will half of all highway bridges, fifteen of the seventeen bridges spanning Portland’s two rivers, and two-thirds of railways and airports; also, one-third of all fire stations, half of all police stations, and two-thirds of all hospitals.
