- an underground nuclear test. Causing vibrations of the experimental bomb. The contribution to the
impact of rock beneath the earth's crust has
earthquakes. Or seismic (UK: seismic waves) are divided into two types:
1. wave in the medium. The wave is spread in a ring around the center earthquakes
can be divided into two types
- primary waves (wave P) longitudinal wave, particles of this type of wave motion direction of motion
of the waves. In every state can get through intermediaries
- Secondary waves (wave S) particles of transverse wave is perpendicular to the direction the wave moves
through a solid medium
2. surface waves. The waves that radiate from the epicenter are two types
- Love waves (Wave of Love: Love wave), wave particles vibrate horizontally. A direction perpendicular to the
motion of the waves
- waves Red Valley (Wave of Rayleigh: Rayleigh wave) wave is oscillating particles in oval. In the direction
of the wave It causes the earth to shake up
2.3. The
impact of the earthquake There are both direct and indirect, such as the ground, causing breakage. Volcano Eruption Building collapse, fire, gas leaks, sewer and water pipes broken. Tsunamis,
landslides Transport routes and cut corruption. Road and rail distorted bend
epidemic. Psychological problems of the victims. The loss of life and property, including
the economy, such as telecommunications outages. A computer system failure Transportation by land
and water. Air suspension People panic It affects investment and insurance in the event of a severe earthquake. The city might be destroyed. And the deaths of many.
