Advocates a magnitude 3.4 earthquake in city in

  China earthquake networks formal determination: January 20, 08 35 points in sichuan

and chengdu city part (30.83 degrees north latitude, 103.20 degrees east longi

tude) a magnitude 3.4 earthquake, focal depth of 21 km.

  According to statistics, the average global every year millions of times

earthquake.In China, the 20th century, the 655

level is above 6 earthquake, 7-9.98 times a magnitude 9 earthquake, more than 7 l0

% of global earthquake at the sam

e level.He Yongnian, a researcher at the Chinese earthquake administration, said

that 41% of the land in our

country, and many large and medium-sized cities in more than 7 degrees of high

earthquake intensity area.T

herefore, in the earthquake comes, how to save themselves, is every citizen must

possess knowledge.

  So, when the earthquake happened, is for us the escape time and opportun

ity?Seismic waves are divided into two kinds: shear wave (S) wave and

longitudinal wave (P wave), before the shear w

aves, when the arrival of transverse wave, is the time when the earthquake is the

strongest.But there was a short la

g between the two waves, transverse longitudinal wave time difference is

different for each of the earthqu

ake, generally between 10 to 30 seconds, we can use this time to escape and to

avoid the danger of the earthquake.

  Because time is short, every half a second is the key to save themselves, so

let’s no hesitate.But don’t count on this more tha

n ten seconds allows us to do a lot of emergency work.Especially when the

crust was shaking, people will feel dizziness,

limb weakness, even very difficult move, at this point, must be immediately her squat.

  China earthquake emergency rescue center of earthquake emergency manual written, w

hen an earthquake that moment, under the conditions allow, need y

ou to learn the standard escape measures and the matters needing attention.

  1.Quickly find main wall

  Use of the space around desk, table or bench, or against an inside walls as a cover, and h

old on the object.If there is no desk or table near you, cover your face and head
