Most earthquakes occur within the upper 15 miles of the earth’s surface. But earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much. In comparison with the total number of earthquakes each year, the number of disastrous earthquakes is very small.[JP]

The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set, it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir, Morocco, was not strong enough to be recorded on distant instruments, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.

The United Nations has played an important part in reducing the damage done by earthquakes. It has sent a team of experts to all countries known to be affected by earthquakes. Working with local geologists and engineers, the experts have studied the nature of the ground and the type of most practical building code for the local area. If followed, these suggestions will make disastrous earthquakes almost a thing of the past.

There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic sea waves, or tsunamis. (These are often called tidal waves, but the name is incorrect. They have nothing to do with tides.)

In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them “tsunamis”, meaning “harbor waves”, because they reach a sizable height only in harbors.

Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An adequate warning system is in use to warn all shores likely to be reached by the waves.

But this only enables people to leave the threatened shores for higher ground. There is no way to stop the oncoming wave.

分析图文资料，完成下列各题。

材料一：

      《史记》记载，“关中之地，于天下三分之一，而人众不过什三。然量其富，什居其六”，这成为

秦与西汉相继定都咸阳、长安，借以控辖全国的经济基础。由于长期的战乱与自然灾害等因素，关中地区经济衰退，隋唐虽定都长安，但主要依赖黄河中下游地区及江南的财赋。由于交通限制，粮食转运耗费巨大，唐前期中央政府常常搬迁至洛阳，以缓解长安及其附近地区的粮食压力。隋炀帝兴建的“东都”洛阳，与长安并称为“二京”，越来越具有战略意义。安史之乱后，唐中央政府全靠东南粮运支撑。史载，唐德宗时，“关中蝗，食草木都尽。旱甚，灞水将竭，井多无水。”百姓嗷嗷待哺，“聚泣田亩”。德宗曾因长安粮尽，得不到犒饷的禁军酝酿哗变，与太子相拥而泣。当得知发自扬州而中途受阻的运船已接近长安，德宗喜不自禁地跑到东宫对太子说：“米已至陕，吾父子得生矣！”
