S U M M A R Y Most earthquake early warning systems (EEWS) developed so far are conceived as either ‘regional’ (network-based) or ‘on-site’ (stand-alone) systems. The recent implementation of nationwide, high dynamic range, dense accelerometer arrays makes now available, potentially in real time, unsaturated waveforms of moderate-to-large magnitude earthquakes recorded at very short epicentral ...

At present, overseas and domestic eco-security early warning research is in the exploratory stage. This paper uses Kizilsu Kirghiz Autonomous Prefecture as the research object and constructs an evaluation index system based on the pressure-state-response (P-S-R) conceptual model. This study analyzes eco-security early warning in the study area using the granger causality test model, the entropy...

the frequent occurrence of currency crises in recent years brought the early warning literature back in the researchers spotlight. in recent years, concept of an early warning system (ews) developed that should be able to identify various costly events, such as currency crises, early enough for policy makers to reduce the costs. this study attempted by using iran's economy quarterly data d...

In this study we implemented and tested the Earthquake Early Warning system PRESTo (PRobabilistic Evolutionary early warning System, Satriano et al., 2011 ) on Greek Ionian islands of Lefkada, Zakynthos Kefalonia. is a free open source platform for regional developed at University Naples Federico II, which currently under experimentation in Southern Italy, area covered by Irpinia Seismic Networ...

It is proposed to install an underwater observing system off the coast of Seattle, Washington and Vancouver, British Columbia in order to allow long-term scientific study of the ocean. The area to be covered corresponds to the Juan de Fuca tectonic plate. Electric power will be provided via a cable similar to a submarine telecommunications cable, and communications will be via fiber optics in t...

A new approach for Earthquake Early Warning Systems (EEWS) is presented that uses wireless, self-organizing mesh sensor networks. To develop the prototype of such IT-infrastructures, we follow a model-driven system development paradigm. Structure and behaviour models of network topologies in specific geographic regions are coupled with wave signal analyzing algorithms, alarming protocols, conve...

Earthquake Early Warning (EEW) is an alert system, based on seismic wave propagation theory, to reduce human casualties. EEW systems mainly utilize technologies through both network-based and on-site methods. The method estimates the hypocenter magnitude of earthquake using data from multiple stations, while predicts intensity measures a single station. Therefore, reduces lead time compared but...
