Earthquakes being among 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 earthquakes (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 statictics, 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.

The study of earthquakes 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, 3 or less is
hardly noticeable. Earthquakes with magnitude of more than 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
earthquakes cause tsunami or a chain of fast moving waves in the ocean that
ripple outward from earthquake epicenter towards coastal areas causing
surmountable damage

Gempa bumi menjadi salah satu bencana alam paling mematikan
Mogok tanpa peringatan sebelumnya, meninggalkan bencana di belakang mereka dengan kerugian yang mengerikan dari kehidupan manusia serta kerugian ekonomi. Secara teknis, sebuah gempa bumi (juga dikenal sebagai tremor, gempa atau gempa) adalah semacam getaran melalui kerak bumi. Gerakan-gerakan yang kuat memicu pelepasan energi yang cepat yang menciptakan gelombang seismik yang bepergian di muka bumi. Gempa bumi biasanya singkat, tapi mungkin mengulang selama periode waktu yang panjang (ilmu bumi 2001). Gempa bumi diklasifikasikan sebagai besar dan kecil. Gempa bumi besar biasanya dimulai dengan sedikit tremor tapi cepat mengambil bentuk shock kekerasan. Getaran dari gempa besar berlangsung selama beberapa hari dikenal sebagai gempa susulan. Gempa bumi kecil biasanya sedikit tremor dan tidak menyebabkan banyak kerusakan. Gempa bumi besar yang dikenal untuk mencatat bangunan dan menyebabkan kematian dan cedera (richter 1935). Menurut beberapa statictics, mungkin ada rata-rata 500.000 gempa bumi setiap tahun tetapi hanya sekitar 100.000 dapat dirasakan dan sekitar 100 atau lebih dapat menyebabkan kerusakan setiap tahun. Studi tentang gempa bumi disebut seismologi. Seismologi mempelajari frekuensi, jenis dan ukuran gempa bumi. Gempa bumi diukur dengan menggunakan pengamatan oleh seismometer. Besarnya gempa bumi dan intensitasnya dicatat pada skala numerik yang dikenal sebagai skala Richter. Pada skala ini, 3 atau kurang adalah hampir tidak terlihat. Gempa bumi dengan magnitude lebih dari 6,5 dapat menyebabkan berat kerusakan (Earth Science. 2001). Efek dari gempa bumi yang kuat di daerah yang dekat nya pusat gempa. Luasnya getaran gempa bumi dan kerusakan lebih lanjut pada wilayah sebagian tergantung pada fitur tanah. Kemungkinan terburuk terjadi kerusakan di daerah yang padat penduduk di mana struktur tidak dibangun untuk menahan guncangan intens. Kerusakan dan korban jiwa yang terjadi selama gempa adalah karena jatuh bangunan dan kaca dan benda terbang. Di daerah tertentu, gempa bumi dapat menyebabkan tanah longsor yang bisa mengubur daerah di bawahnya. Kapal selam kuat gempa bumi penyebab tsunami atau rantai gelombang bergerak cepat di laut yang riak keluar dari pusat gempa ke daerah pesisir menyebabkan kerusakan diatasi
