How to Prepare for Earthquakes

Ideally, people would like to know when anearthquake is going to happen and how bad it willbe. Inboth Japan and China, people have longbelieved that earthquakes can be forecast. In Japan,scientistshave wired the Earth and sea to detectmovements. The Chinese have traditionally watchedanimalsand plants for warning signs of earthquakes. For example, the Chinese have noted thatbefore anearthquake, hens' behavior changes — they refuse to enter their cages at night. Theyhave also noticedthat snakes come out of the ground to freeze to death and that dogs bark alot, even normally quietdogs. Before the Hanshin earthquake in Japan, there were reports oflarge schools of fish swimmingnear the surface of the water. Certain birds, like pigeons, alsoseemed to be especially noisy, and werereported to be flying in unusual patterns before theearthquake. Perhaps most interesting, and mosteasily measured, is a chemical change inground water before a quake. Experimental data seem toindicate that the amount of radon (Rn)in the water under the surface of the Earth waxes before anearthquake.

People would also like to be able to prevent the great destruction of property caused byearthquakes.

After all, most of the people who die in earthquakes are killed by falling buildings. Therefore,buildingstructures that can withstand the power of earthquakes is a major concern. Steelseems to be the bestmaterial, but not if it is welded to form a rigid structure. Many newstructures are built with a new typeof steel joint, an I-joint, which appears to be the mostdurable type of joint. These joints of steel canmove without breaking. Also, to preventproperty damage, architects now design buildings so that thebuilding's columns andhorizontal beams are of equal strength, and vertical support columns areinserted deep intosolid soil. In addition, many new houses have relatively light roofs and strong walls.

Concrete pillars for highway bridges that previously only had steel rods inside are nowenclosed in steel.

Besides working to improve building structures, people in areas where earthquakes arecommonneed to prepare for the possibility of a great earthquake. They should regularly checkand reinforcetheir homes, place heavy objects in low positions, attach cupboards and cabinetsto walls, and fastendoors so that they will not open accidentally during an earthquake.

In addition to preparing their houses, people in these regions need to prepare themselves.Theyshould have supplies of water and food at home and at work. It is best to store severalgallons of waterper person. It is also important to have something that can clean water and killbacteria, so water fromother sources can be made safe to drink. Store one week's food foreach person. Earthquake survivalsupplies include a radio receiver, a torch, extra batteries, first-aid supplies, a spade, a tent, some rope,and warm clothing. Experts also suggest the following:

Keep a fire extinguisher handy. You should have one at home, at work, and in your car (if youhaveone). The fire extinguisher should be able to put out any type of fire. Have the proper toolsto turn offgas and water lines if necessary. Arrange an auxiliary cooking and heating sourcethat can be usedoutside. One alternative is a portable camp stove with small cans of gas.Keep a pair of heavy,comfortable shoes or boots in your home, at work, and in your vehicle. Ifthere is an earthquake, therewill be lots of fragments of broken glass. Light shoes will notprotect your feet as well as heavy shoeswill.

Every family needs to have earthquake emergency plans. How will family members leave theareaduring the chaos following an earthquake? Everyone should agree on a meeting pointoutside of thearea — perhaps in a town several miles away. Also important is an arrangementfor family members tocommunicate if there is an earthquake. If an earthquake happens in alarge city, many of the telephonelines within the city are likely to be down. The few remainingworking lines will be busy with the callsthat naturally occur after a disaster and it will be difficultto call from one part of the city to another. Itmight, however, be possible to call outside thecity. A sensible arrangement is to have all of themembers of the family call to check in with afriend or relative who lives more than a hundred milesaway.

Although scientists still cannot predict earthquakes, they are learning a great deal about howthelarge plates in the earth's crust move, the stresses between plates, how earthquakes work,and thegeneral probability that a given place will have an earthquake. Someday soon it mayactually becomepossible to predict earthquakes with accuracy. However, even if predictionbecomes possible, peoplewho live in areas where earthquakes are a common occurrence willstill have to do their best to preventdisasters by building structures that are resistant toground movement and by being personallyprepared. These precautions can make a greatdifference in saving lives and preventing the loss ofhomes. Education concerning how tosurvive an earthquake should be a major emphasis for allgovernment programs andearthquake-related research projects.
