JAWABAN:

The social function of report text is to describe the way things are, with a reference to a range of natural, man-made, and social phenomena in our environment.

The Generic Structure

1. General Classification

Earthquakes being the most deadly natural hazards strike without any prior warning leaving catastrophe in their wake with terrible loss of human lives as well as economic loss.

Technically, an earthquake (also known as tremor, quake or temblor) is a kind of vibration through earth’s crust. These powerful movements trigger a rapid release of energy that creates seismic waves that travel through the earth. Earthquakes are usually brief, but may repeat over a long period of time (earth science 2001).

Earthquakes are classified as large and small. Large earthquakes usually begin with slight tremors but rapidly take form of violent shock. The vibrations from a large earthquake last for few days known as aftershocks. Small earthquakes are usually slight tremors and do not cause much damage. Large earthquakes are known to take down buildings and cause death and injury (Richter 1935). According to some statistics, there may be an average of 500,000 earthquakes every year but only about 100,000 can be felt and about 100 or so can cause damage each year.

2. Description  

The study of earthquake is called seismology. Seismology studies the frequency, type and size of earthquakes. Earthquakes are measured using observations by seismometers. The magnitude of an earthquake and its intensity is recorded on a numerical scale known as Richter scale. On this scale, 6.5 can cause heavy damage. (Earth Science. 2001)

The effects of an earthquake are strongest in the area which is near its epicenter. the extent of the earthquake vibration and further damage to the region is partly dependent on the features of the ground. the worst possible damage occurs in the densely populated areas where structures are not built to withstand intense shaking. Damage and loss of life incurred during earthquake is due to falling buildings and flying glass and objects. In certain areas, an earthquake can cause mudslides that can bury areas under it. Powerful submarine earthquake cause tsunami or a chain of fast moving waves in the ocean that ripple outward from earthquake epicenter towards coastal areas causing surmountable damage (http\\: http://www.USGS.Org). On a average, 1,000 earthquakes with intensities of 5.0 or greater than recorded each year.

As Indonesia is situated in the “Ring of Fire”, it is not more prone to earthquakes. According to United States geological survey (USGS, earthquake hazards program), till now Indonesia has witnessed five great earthquakes with the magnitude ranging from 8.5 to 9.1. These earthquake cause major destruction in the places they occurred. One of the major earthquakes that hit Indonesia was “2004 Indian Ocean tsunami). It was the deadliest natural disaster in the area. Its magnitude was 9.1-9.3. Heavy loss of human lives was witnessed and damage was felt as far as east coast of Africa (http://www.USGS.Org)

Earthquakes have been a source of terror to people since ancient times, but only for the last few hundred years serious attempts have been made to understand them. Many methods have been developed to predict earthquakes despite all the research efforts by seismologists. The prediction cannot be made to a specific day or month. In future perhaps scientists will be able to predict earthquakes exactly but for now science has yet to provide answers.

PEMBAHASAN:

Report text merupakan sebuah teks yang menghadirkan informasi tentang suatu hal secara apa adanya. Teks jenis ini sering dikatakan sebagai "saudara kembar" descriptive text sehingga wajar banyak siswa "bingung" cara membedakan kedua teks tersebut. sebenarnya teks report dan descriptive mempunyai perbedaan yang cukup jelas, meski nampak keduanya dikatakan sebagai "saudara kembar" sekalipun.

Di dalam report text itu biasanya berisi dengan fakta-fakta yang bisa dibuktikan secara ilmiah

Generic structure  of Report text:

• General Classification: Pernyataan umum yang menerangkan subjek laporan, keterangan, dan klasifikasinya.  
• Description: tells what the phenomenon under discussion ; in terms of parts, qualities, habits or behaviors; Pada bagian ini biasanya memberikan gambaran fenomena-fenomena yang terjadi; baik bagian-bagiannya, sifat-sifatnya, kebiasaannya, ataupun tingkah lakunya. Intinya adalah penjabaran dari klasifikasi yang disajikan dengan ilmiah
