Real-time GNSS for fast seismic source inversion and tsunami early warning
… GNSS for natural hazards prediction and early warning has been exploited intensively in recent years, e.g., landslides and volcanic eruptions monitoring. Of particular note, compared with traditional seismic instruments, GNSS does not saturate or tilt in terms of co-seismic displacement …

Tsunami Warning System
<p>The effects of a tsunami on a coastline can be devastating. In an attempt to mitigate the damages caused by tsunamis, and to provide coastal communities with evacuation alerts, it is essential to have early warning systems installed offshore. Tsunami early warning systems can detect the …

GPS based analysis of earthquake induced phenomena at the Sunda Arc
… The most severe consequences thereby arise from tsunamis triggered by these subduction-related earthquakes, as the Sumatra-Andaman event in 2004 showed. In order to enable efficient tsunami early warning, which includes the estimation of wave heights and arrival times, it is necessary to combine …

Landslide generated tsunamis : numerical modeling and real-time prediction
Submarine landslides can generate local tsunamis posing a hazard to human lives and coastal facilities. Two major related problems are: (i) quantitative estimation of tsunami hazard and (ii) early detection of the most dangerous landslides. This thesis focuses on both those issues by providing …

Potential for tsunami detection and early-warning using space-based passive microwave radiometry
The threat of a tsunami in coastal communities is considerable, especially in the Pacific and Indian Oceans. Current warning systems consist of two networks: (1) a network of seismometers, and (2) a network of sea level gauges and bottom pressure recorders. Bottom pressure recorders communicate …

Tsunami Excitation Estimation from Real-time GNSS
Tsunami early warning systems currently comprise modeling of observations from the global seismic network, deep-ocean DART buoys, and a global distribution of tide gauges. While these tools work well for tsunamis traveling teleseismic distances, saturation of seismic magnitude estimation in the …

Defining historical earthquake rupture parameters and proposed slip distributions through tsunami modeling in south-central Chile
Reliable tsunami early warning forecasts rely on accurate initial modeling conditions and interpretations of subduction zone behavior in a multi-century perspective. GPS and seismologic data were introduced this past century to study rupture dynamics in detail, however limited information is known …

Early warning system guidance to mitigate flash flood impacts in Petra region, Jordan
… controlled easily, the need for more effective early warning systems has become extremely important. United Nations International Strategy for Disaster Reduction (UNISDR) and many researchers assumed that if an effective tsunami early warning system had been in place in the Indian Ocean region …

Atmospheric and Ionospheric Responses to Acoustic and Gravity Waves Driven by Earthquakes and Tsunamis
… leading potentially to the development of NH early-warning systems. Although general concepts underlying their coupling mechanisms are well understood, recent computational capabilities, supported by high temporal and spatial density of observations, have reached the level where such processes …
