A Great Quake Coming?

Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they
can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed
hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's
bound to happen someday. At least seven active fault（断层）lines run through the San Francisco area. Faults
are places where pieces of Earth ' s crust（地壳）slide past each other. When these pieces slip , the ground
shakes.
To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-
dict how bad the damage might be when the next one happens.
One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists
had assumed at the time. During small earthquakes,faults rupture（断裂）at about 2.7 kilometers per second.
During bigger quakes,however,ruptures can happen at rates faster than 3.5 kilometers per second.
At such high speeds,massive amounts of pressure build up,generating underground waves that can
cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses（脉冲）traveled
away from the city during the 1906 event.As bad as the damage was,it could have been far worse.
Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that
earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data,
however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62
percent.
New buildings in San Francisco are quite safe in case of future quakes.Still,more than 84 percent of the
city's buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive
damage.
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a
while.According to the new research,however,it's not a matter of"if" the Big One will hit.It's just a mat-
ter of when.

The highest speed of fault ruptures in the 1906 quake was more than 3.5 kilometers per second.

Study Helps Predict Big Mediterranean Quake

1.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.
2.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 deter-mine the future possibility of similar large shocks.
3.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.
4.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 pro-duce 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.

The earthquake prediction devices developed by Ms.Shaw are being widely used in the world.

Study Helps Predict Big Mediterranean Quake

1.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.
2.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 deter-mine the future possibility of similar large shocks.
3.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.
4.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 pro-duce 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.

Tourism

People travel for a lot of reason.Some tourists go to see battlefields or religious shrines.Others are looking for culture,or simply want to have their picture taken in front of famous places.But most European tourists are looking for a sunny beach to lie on.
Northern European are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it. Residents of cities like London,Copenhagen,and Amsterdam spend a lot of their winter in the dark because the days are so short,and much of the rest the year in the rain.This is the reason the Mediterranean has always attracted them.Every summer, more than 25 million people travel to Mediterranean resort and beaches for their vacation.They all come for the same reason:sun!
The huge crowds mean lots of money for the economies of Mediterranean countries.Italy's
30,000 hotels are booked solid every summer.And 13 million people camp out on French beaches, parks and roadsides.Spain's long sandy coastline attracts more people than anywhere else.37 million tourists visit yearly,or one tourist for every person living in Spain.
But there are signs that the area is getting more tourism than it can hand1e; The Mediterranean is already one the most polluted seas on earth.And with increased tourism,it's getting worse.The French can't figure out what to do with all the garbage left by campers around St. Tropez.And in many places,swimming is dangerous because of pollution.
None of this,however,is spoiling anyone's fun.The Mediterranean gets more popular every year with tourists.Obviously,they don't go there for clean water and solitude.They tolerate traffic jams and seem to like crowded beaches.They don't even mind the pollution.No matter how dirty the water is,the coastline still looks beautiful.And as long as the sun shines,it's still better than sitting in the cold rain in Berlin,London,or Oslo.

The latter half of the last sentence in paragraph 3,"or one tourist for every person living in Spain"means______.
A:all the 37 million people living in Spain are tourists
B:every year almost as many tourists visit Spain as there are people living in that country
C:every person living in Spain has to take care of a tourist
D:every Spanish is visited by a tourist every year

A Great Quake Coming?

Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they
can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed
hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's
bound to happen someday. At least seven active fault（断层）lines run through the San Francisco area. Faults
are places where pieces of Earth'S crust（地壳）slide past each other.When these pieces slip,the ground
shakes.
To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-
diet how bad the damage might be when the next one happens.
One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists
had assumed at the time. During small earthquakes,faults rupture（断裂）at about 2.7 kilometers per second.
During bigger quakes,however.ruptures can happen at rates faster than 3.5 kilometers per second.
At such high speeds,massive amounts of pressure build up,generating underground waves that can
cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses（脉冲）traveled
away from the city during the 1906 event.As bad as the damage was,it could have been far worse.
Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that
earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data,
however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62
percent.
New buildings in San Francisco are quite safe in case of future quakes.Still,more than S4 percent of the
city’s buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive
damage.
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a
while.According to the new research,however,it's not a matter of"if" the Rig One will hit.It',just a mat-
ter of when.

Scientists will be able to predict the exact time of an earthquake soon.
A:Right
B:Wrong
