“…The EQIM (Yang and Huang 2009) system official timely issues alerts regarding the latest seismic events from CENC over the Chinese seismic network after large earthquakes in China and other regions of the world. PEEW (Peng et al 2011) produces alert messages for the Beijing capital region (36°N-42°N, 113.5°E-120°E) after a medium or large earthquake (M l [ 3). The earthquake information generated from the two systems includes three elements of a typical seismic event: origin time, epicenter, and magnitude.…”

In hazard management, earthquake researchers have utilized GIS to ease the process of managing disasters. Researchers use WebGIS to assess hazards and seismic risk. Although they can provide a visual analysis platform based on GIS technology, they lack a general description in the extensibility of WebGIS for processing dynamic data, especially real-time data. In this paper, we propose a novel approach for real-time 3D visual earthquake information publishing model based on WebGIS and digital globe to improve the ability of processing real-time data in systems based on WebGIS. On the basis of the model, we implement a real-time 3D earthquake information publishing system-EqMap3D. The system can not only publish realtime earthquake information but also display these data and their background geoscience information in a 3D scene. It provides a powerful tool for display, analysis, and decisionmaking for researchers and administrators. It also facilitates better communication between researchers engaged in geosciences and the interested public.

“…Over the last two decades, several countries have built operational earthquake early warning (EEW) systems, including Japan (Hoshiba et al, 2008), Mexico (Espinosa-Aranda et al, 1995), Romania (Mărmureanu et al, 2011), Turkey (Erdik et al, 2003), Taiwan (Hsiao et al, 2011), and China (Peng et al, 2011). Other countries, such as the United States (Böse, Allen, et al, 2013), Italy (Satriano et al, 2011), and Switzerland (Behr et al, 2015), are currently developing systems or evaluating algorithms in their seismic real-time networks.…”

“…Japan, Taiwan, Mexico and California, for example, already have operational EEWSs (Horiuchi et al, 2005, Wu and Zhao, 2006, Espinosa-Aranda et al, 2009, Böse et al, 2009, Böse et al, 2007. EEWSs are also under development and testing in other regions of the world, such as Italy, Turkey and China (Satriano et al, 2010;Zollo et al, 2014, Alcik et al, 2009, Peng et al, 2011. Finally, a feasibility study is in progress in Spain (Carranza et al, 2013).…”

The south of the Iberian Peninsula is a region situated at the convergence of the Eurasian and African plates. This region experiences large earthquakes with a long separation in time, the best known of which is the great 1755 Lisbon Earthquake (i.e., maximum macroseismic intensity, I max =X), which occurred SW of San Vicente Cape (SW Iberian Peninsula). The high risk of damaging earthquakes has recently lead Carranza et al.(2013) to investigate the feasibility of an EEWS in this region. The analysis of the geometrical situation between the Iberian seismic networks and the San Vicente Cape area led the authors to conclude that a threshold-based approach, which would not require the real-time location of the earthquake, might be the best option for EEWS in SW Iberia.The current work explores this hypothesis, and proposes a new EEW approach that extends the standard P-wave threshold based single station analysis to the whole network.The proposed method allows the real-time estimation of the potential damage at stations that are triggered by P-waves, as well as at the not-triggered ones, giving the advantage of a greater lead-time for the release of alerts. Results of tests made with synthetic data mimicking the scenario of the great 1755 Lisbon Earthquake, and those obtained by applying the new approach to available recordings, indicate that an EEW estimation of the potential damage associated with an event in the San Vicente Cape area can be obtained for a very large portion of the Iberian Peninsula.2
