New Aims Concept of GPS Shield for Fast Tsunami Alert

For almost two years since the biggest Tsunami happened in Asian Region, many scientist still doing some research on it. The German Indonesia Tsunami Early Warning System (GITEWS) of the Research Center for Geosciences in Postdam Germany. The most remarkable concept changing that it was offered last year is: when they take the new ground - based systems takes real time measurement of vertical ground motion - the type of fault movement more likely to produce tsunamis.

The German conception of the establishment of a Tsunami Early Warning System for the Indian Ocean is based on different kinds of sensor systems. In ca. 90 % a tsunami is generated by an earthquake but also volcanic eruptions and landslides may be the triggering events. The conception aims at achieving indicators of a tsunami and its dimension by the analysis of different measurements at a very early stage. While a tsunami wave in the wideness of the sea spreads out with a speed up to 700 km/h, in the treated region a period of about 20 minutes elapses between the wave's generation and the first contact with the Indonesian mainland. In this timeframe the sensors, which will be installed at different locations inside the considered propagation areas, are able to rapidly detect deviations from normality (anomalies).

The sensors of the Tsunami Early Warning System comprise
seismometers, GPS instruments, tide gauges and buoys as well as ocean bottom pressure sensors.

In a central
warning center in Indonesia remarkable sensor data immediately is verified with a multitude of pre-taylored tsunami simulations to derive and to deliver trusted warnings.

By the involvement of local scientists and technicians in the framework of the
Capacity Building Programme and by targeted actions to raise awareness regarding the tsunami threat the realisation of a long-term strategy towards the prevention of disastrous losses of lifes is aimed at
GPS Land Stations are installed at the coastline of the Indonesian mainland and at the islands off Sumatra. Their main task is the detection of horizontal and vertical deformations of the earth's surface due to a strong earthquake. This can be done in a very short time and with an accuracy of few centimeters.

Both the buoys and the tide gauges are equipped with GPS instruments, too, which monitor their particular location and shifting regarding the horizontal position and the altitude.

Furthermore, new technologies like
GPS reflectometry are studied and evaluated regarding tsunami early warning issues

Thanks for the insightful information but what about the dissemination system. It's great that they are detecting the destructive wave but unless a multi-dissemination system is established the information is not communicated to the millions living along the coasts. There needs to be sirens and text messaging systems installed to get the word out in a timely manner.

Thoughts.
