Earthquakes
the most deadly natural hazards

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 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, 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 epicanter

Gempa bumi
paling mematikan alami bahaya gempa bumi. Menjadi bahaya alam yang 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 s. 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 terakhir untuk 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 masing-masing 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 ini , 3 atau kurang hampir tidak terlihat. Gempa bumi dengan magnitude lebih dari 6,5 dapat menyebabkan kerusakan berat (ilmu bumi. 2001). Efek dari gempa bumi yang kuat di daerah yang dekat epicanter nya
