  Study Helps Predict Big Mediterranean Quake

  Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.

  Using radiocarbon dating techniques, simulations and computer models, the researchers recreated the ancient disaster in order to identify the responsible fault. ‘We are saying there is probably a repeat time of 800 years for this kind of earthquake,' said Ms Beth Shaw, an earthquake scientist at the University of Cambridge, who led the study. Scientists study past earthquakes in order to determine the future possibility of similar large shocks.

  Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region, Ms. Shaw said. The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300, which means the next powerful one could come in the next 100 years, she added in a telephone interview.

  Ms. Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion, she said. Their computer model suggested an 8 magnitude quake on the fault would produce a tsunami that floods the coastal regions of Alexandria and North Africa, the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik. This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta, likely killing tens of thousands of people, she said.

  16. The fault, which was overlooked before, has been closely studied by scientists.

  A. Right B. Wrong C. Not mentioned

  19. Scientists predict that the next powerful earthquake in the eastern Mediterranean may take place some time before 2100.

  A. Right B. Wrong C. Not mentioned

  20. Ms. Shaw has her colleagues help her in the study of earthquake prediction.

  A. Right B. Wrong C. Not mentioned

  21. Ms. Shaw measured the movement of either side of the fault to identify the magnitude of the earthquake taking place in AD 365.

  A. Right B. Wrong C. Not mentioned

  22. The earthquake prediction devices developed by Ms. Shaw are being widely used in the world. A. Right B. Wrong C. Not mentioned

  A Strong Greenhouse Gas

  Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmosphere1, it absorbs heat radiating from Earth’s surface. That’s why methane is a major contributor to the planet’s increasing temperature rise-or global warming. Molecule for molecule, methane’s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide2, the most abundant greenhouse gas.

  With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it’s no surprise that methane released by livestock is one of the chief global sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wet lands.

  Greenhouse gases like methane and carbon dioxide make up only a small part of Earth’s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun’s heat and warm the planet, life as we know it couldn’t exist3. But in the last 200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.

  Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.

  Cows munch mostly grasses and hay-yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and break down cellulose and fiber into digestible nutrients. A cow couldn’t live without its microbes. As the microbes digest cellulose, they release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it make them very gassy. It’s part of their normal digestion process. When they chew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.

  That’s why we say livestock gas is also a major factor of causing the global warming.
