Soil Liquefaction in Padang due to Padang Earthquake 30September 2009
Abstract: The Padang
earthquake of M7.6 on 30 September 2009 (30S’09) caused damage to buildings,
houses, public water facilities, and road ways. Several buildings were damaged
due to liquefaction. This paper describes the liquefaction potential in Padang
based on the site observation and analytical examination. The liquefaction was
observed at a number of sites including roadway, river bank and play ground.
The samples of sand boils were sent to the laboratory to determine the soil
grain size distributions. It is found that the fine-sand (diameter less than
0.4 mm) content of the liquefied soil samples is more than 65%. This type of
soils satisfies the criteria of liquefaction susceptibility. Based on the field
soil test data, the liquefaction potential of sites is also examined. The
results show that the observed locations have liquefaction potential.
