China Seismic Intensity Scale

The China Seismic Intensity Scale (CSIS) is a national standard in the People's Republic of China used to measure seismic intensity. Similar to SMC-92 on which CSIS drew reference, seismic impacts are classified into 12 liedu (Chinese: 烈度; pinyin: lièdù, literally "degree of violence"), from I for insensible to XII for landscape reshaping. The scale was initially formalized by the China Earthquake Administration (CEA) in 1980, therefore often referred to by its original title as "China Seismic Intensity Scale (1980)". It was later revised, and adopted as a national standard, or Guobiao, series GB/T 17742-1999 by then National Quality and Technology Supervision Administration (now General Administration of Quality Supervision, Inspection, and Quarantine of P.R.C., AQSIQ) in 1999.[2]

Liedu Senses by people on the ground Degree of building damage Other damages Horizontal motion on the ground
Damages Mean damage index Peak acceleration m/s2 Peak speed m/s
I Insensible
II Sensible by very few still indoor people
III Sensible by a few still indoor people Slight rattle of doors and windows Slight swing of suspended objects
IV Sensible by most people indoors, a few people outdoors; a few wake up from sleep Rattle of doors and windows Obvious swing of suspended objects; vessels rattle
V Commonly sensible by people indoors, sensible by most people outdoors; most wake up from sleep Noise from vibration of doors, windows, and building frames; falling of dusts, small cracks in plasters, falling of some roof tiles, bricks falling from a few roof-top chimneys Rocking or flipping of unstable objects 0.31
(0.22 - 0.44)
0.03
(0.02 - 0.04)
VI Most unable to stand stably, a few scared to running outdoors Damages - Cracks in the all, falling of roof tiles, some roof-top chimneys crack or fall apart 0 - 0.10 Cracks in river banks and soft soil; occasional burst of sand and water from saturated sand layers; cracks on some standalone chimneys 0.63
(0.45 - 0.89)
0.06
(0.05 - 0.09)
VII Majority scared to running outdoors, sensible by bicycle riders and people in moving motor vehicles Slight destruction - localized destruction, crack, may continue to be used with small repairs or without repair 0.11 - 0.30 Collapse of river banks; frequent burst of sand and water from saturated sand layers; many cracks in soft soils; moderate destruction of most standalone chimneys 1.25
(0.90 - 1.77)
0.13
(0.10 - 0.18)
VIII Most swing about, difficult to walk Moderate destruction - structural destruction, continued usage requires repair 0.31 - 0.50 Cracks appear in hard dry soils; severe destruction of most standalone chimneys; tree tops break; death of people and cattle caused by building destruction 2.50
(1.78 - 3.53)
0.25
(0.19 - 0.35)
IX Moving people fall Severe destruction - severe structural destruction, localized collapse, difficult to repair 0.51 - 0.70 Many cracks in hard dry soils; possible cracks and dislocations in base rocks; frequent land slide and collapses; collapse of many standalone chimneys 5.00
(3.54 - 7.07)
0.50
(0.36 - 0.71)
X Bicycle riders may fall; people in unstable state may fall away; sense of being thrown up Most collapse 0.71 - 0.90 Cracks of mountain rocks and earthquake fractures; destruction in top arches of base rocks; root damage or collapse of most standalone chimneys 10.00
(7.08 - 14.14)
1.00
(0.72 - 1.41)
XI Wide spread collapse 0.91 - 1.00 Earthquake fractures extend a long way; many mountain rock cracks and land slide
XII Drastic change in landscape, mountains, and rivers
