European Commission’s satellite analysis supporting international Tsunami information gathering efforts


The immediate response by the European Commission’s Joint Research Centre has consisted of:

* Analysis of regional maps depicting Tsunami flooded zones, affected population and natural resources.

A preliminary estimate of the inundation zone was produced by calculating the area of less than 10m and 20m elevation contour lines within 5km of the coastline for the entire region. This information was cross-checked with global population density data to estimate the likely population affected. Regional land cover maps were used to estimate impact on natural resources.

* Analysis of country maps depicting affected population & infra-structure.

DG JRC acquired information and data through open sources to produce thematic country scale maps depicting affected population, infra-structure and natural resources. Additional geo-political and other relevant information is now being integrated while similar maps for other affected zones will either be created or integrated from other sources.

* Analysis of in-country maps depicting damage analysis/assessments for specific Tsunami affected zones.

Together with various agencies and pictures as close as 1 meter or less to the land, it has been possible to prepare damage analysis/assessments for disaster affected zones.

Follow up action

Work will continue on damage and situation analysis/assessments over the region. A comprehensive Tsunami information system will be maintained by DG JRC to assist EU operations. An assessment of the strengths and weaknesses of European and international mapping and satellite-based efforts to be deployed in such situations will also be made

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
