First the ground shook in Haiti, then Chile and Turkey. The earthquakes keep coming hard and fast this year, causing people to wonder if something evil (邪恶的) is happening underfoot.

It’s not.

While it may seem as if there are more earthquakes occurring, there really aren’t. the problem is what’s happening above ground, not underground, experts say.

More people are moving into big cities that happen to be built in quake zones, and they’re rapidly putting up buildings that can’t withstand (经受) earthquakes, scientists believe.

And around-the-clock news coverage (报道) and better earthquake monitoring make it seem as if earthquakes are ever-present.

“I can definitely tell you that the world is not coming to an end,” said Bob Holdsworth, an expert in tectonics (筑造学) at Durharn University in the UK.

A 7.0 magnitude quake in January killed more than 230,000 people in Haiti. Last month, an 8.8 magnitude quake--- the fifth-strongest since 1900—killed more than 900 people in Chile. And two weeks ago, a 6.0 magnitude quake struck rural eastern Turkey, killing at least 57 people.

On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9, according to the US Geological Survey. This year is off to a fast start with 40 so far—more than in most years for that time period.

But that’s because the 8.8 quake in Chile generated a large number of strong aftershocks, and so many quakes this early in the year skews (扭曲) the picture, said Paul Earle, a US seismologist (地震学家).

Also, it’s not the number of quakes, but their devastating (破坏性的) impacts that gain attention, with the death tolls (死亡人数) largely due to construction standards and crowding, Earle added. “The standard mantra (咒语) is earthquakes don’t kill people, buildings do, ” he said.

There have been more deaths over the past decades from earthquakes, said University of Colorado geologist Roger Bilham. In an opinion column last month in the journal Nature, Bilham called for better construction standards in the world’s big cities.

Of the 130 cities worldwide with populations of more than 1 million, more than half are prone (倾向于) to earthquakes, Bilham said.

Developing nations, where populations are booming, don’t pay attention to earthquake preparedness, Bilham said.” If you have a problem feeding yourself, you’re not really going to worry about earthquakes.”

Another reason quakes seem worse is that we’re paying attention more. The Haiti earthquake quickly followed by the 8.8 in Chile made everyone start to think.

But it won’t last, said US disaster researcher Deniis Mileti. “People are paying attention to the violent planet we’ve always lived on,” Mileti said.” Come back in another six months if there has been no earthquakes, most people will have forgotten it again. ”
