REAL-TIME SEISMOLOGY AND EARTHQUAKE DAMAGE MITIGATION

Real-time Seismology and Earthquake Damage Mitigation

■ Abstract Real-time seismology refers to a practice in which seismic data are collected and analyzed quickly after a significant seismic event, so that the results can be effectively used for postearthquake emergency response and early warning. As the technology of seismic instrumentation, telemetry, computers, and data storage facility advances, the real-time seismology for rapid postearthqua...

Instrumentation in Earthquake Seismology

Is Earthquake Seismology a Hard, Quantitative Science?

Our purpose is to analyze the causes of recent failures in earthquake forecasting, as well as the difficulties in earthquake investigation. We then propose that more rigorous methods are necessary in earthquake seismology research. First, we discuss the failures of direct earthquake forecasts and the poor quantitative predictive power of theoretical and computer simulation methods in explaining...

Real-time damage detection of bridges using adaptive time-frequency analysis and ANN

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

The 2007 Pisco, Peru, earthquake (M8.0): seismology and geodesy

S U M M A R Y We investigate the 2007 Pisco, Peru, earthquake (M8.0) using seismological and geodetic data. Analysis of teleseismic records indicates that the earthquake is characterized by a steadily increasing moment rate, with the maximum occurring between about 55 and 70 s and the associated slip occurring about 40 km south of the epicentre. We combine InSAR data from L-band (ALOS) and C-ba...
