S U M M A R Y We explore a practical approach to earthquake early warning in southern California by determining a ground-motion period parameter τc and a high-pass filtered displacement amplitude parameter Pd from the initial 3 s of the P waveforms recorded at the Southern California Seismic Network stations for earthquakes with M > 4.0. At a given site, we estimate the magnitude of an event fr...

Earthquake Early Warning System (EEWS) is one of the effective ways to mitigate earthquake damage and can provide few seconds to tens of seconds of advanced warning time of impending ground motions, allowing for mitigation measures to be taken in the short term. In the present paper, we develop an integrated onsite EEWS called EDAS-MAS, which is based on the physical characteristics of the P-wa...

Abstract In this study, we examine the scientific feasibility of an Earthquake Early Warning System in Tehran, Iran, by integration Tehran Disaster Mitigation and Management Organization (TDMMO) accelerometric network PRobabilistic Evolutionary early warning SysTem (PRESTo). To evaluate performance TDMMO-PRESTo system providing reliable estimations earthquake parameters available lead-times for...

Early warning systems are key components of strategies to reduce risk. This research, by adopting a systematic approach in the management of the risk of desertification and by including previously developed models and systems, offers an integrated efficient structure in terms of early warning for the risk of desertification as a pilot system for semi-arid areas of west Golestan Province in IRAN...

The ultimate goal of earthquake early warning (EEW) is to provide local shaking information to users before the strong shaking from an earthquake reaches their location. This is accomplished by operating one or more real-time analyses that attempt to predict shaking intensity, often by estimating the earthquake’s location and magnitude and then predicting the ground motion from that point sourc...

The catastrophic tsunamis generated by the great Indonesia earthquake triggered on December 26 th , 2004, warned the coastal community on preparedness and constructing safe structures to resist against such events. Earthquake occurs suddenly without warning and bulk of destruction takes place within a short period of time. Similarly, when tsunami strikes, there will be a tremendous loss and dam...

The Multi-Parameter Wireless Sensing (MPwise) system is an innovative instrumental design that allows different sensor types to be combined with relatively high-performance computing and communications components. These units, which incorporate off-the-shelf components, can undertake complex information integration and processing tasks at the individual unit or node level (when used in a networ...

Rapid urbanisation, the interconnection of economies and growing dependence on technology makes modern society increasingly vulnerable to natural disasters. In case of earthquakes, the mitigation of seismic risk in urban and industrial area can be effectively accomplished by Earthquake Early Warning systems (EEWS), which performs real-time event detection and characterization, issues rapid aler...
