This paper is a progress report of a MCEER research project on the development of multihazard protection technologies for critical facilities. One important component is to consider earthquake and earthquake induced hazards (e.g. fire, haz-mat leakage, power outrage, etc). This paper is concerned with earthquake and subsequent fire hazards. Records from historical earthquakes show that sometime...

Niumiangou valley, the epicenter of 12 May 2008 Wenchuan earthquake (MS 8.0), became an area with frequent and dense debris flow disasters post-earthquake. Based on in situ investigations after 14 August 2010 a series gathered data, characteristics dynamic analyses post-earthquake flows valley were conducted, then their hazard degree was assessed. Some research conclusions are obtained: (1) the...

Strong strain and pore pressure changes are observed after three Mw 4.5+ local one 7.2 regional earthquake during 2010–2017 in borehole strainmeters near Anza, California. The change emerges immediately the earthquakes lasts 40–100 days with amplitudes up to 10−7, larger than coseismic offsets. exhibits at some boreholes a delay of 4–10 others. A joint analysis postseismic suggests that strains...

Catastrophic earthquake-induced landslides can occur on slopes composed of loosened and fractured rock masses. Although it is impossible to prevent such landslides, estimation the susceptibility useful for risk management. An index (ISEL) was developed by using helicopter-borne electromagnetic resistivity data. However, ISEL has not yet been validated through analysis pre-earthquake In this stu...

A strong earthquake-induced hazard has obvious long-term and spatial heterogeneity, which will result in continuous social economic losses. Measuring the socioeconomic development level of disaster area is great significance for reconstruction after an earthquake. First, kernel density estimation (KDE) used to analyze effects 10 extremely earthquake-stricken areas Wenchuan earthquake this paper...
