First satellite map of Haiti earthquake

15.01.2010
A major 7.0-magnitude earthquake struck the Haitian capital of Port-au-Prince on 12 January, causing major casualties and damage. The quake was followed by several aftershocks with magnitudes over 5.0.

Such a powerful earthquake can make current maps suddenly out of date, causing additional challenges to rescue workers on the ground. Earth observation satellite images can help rescue efforts by providing updated views of how the landscape and the infrastructure have been affected.

Following the event, the French Civil Protection authorities, the Public Safety of Canada, the American Earthquake Hazards Programme of USGS and the UN Stabilisation Mission in Haiti requested satellite data of the area from the International Charter on ‘Space and Major Disasters’. The initiative, referred to as ‘The Charter’, is aimed at providing satellite data free of charge to those affected by disasters anywhere in the world.

To meet the requirements of the rescue teams in Haiti, Very High Resolution imagery is needed from both optical and radar sensors. Through the Charter, the international space community is acquiring satellite imagery as quickly as possible. Currently, data are being collected by various satellites including Japan’s ALOS, CNES’s Spot-5, the U.S.’s WorldView and QuickBird, Canada’s RADARSAT-2 and ESA’s ERS-2 and Envisat.

Satellite imagery acquired immediately after the event is used to generate emergency maps to provide rescue services with an overview of the current state of the area. These can be compared with situation maps generated from archived satellite data to identify major changes on the ground caused by the disaster.

Comparison of the maps from before and after the event allows areas that have been hit hardest to be distinguished and identify passable routes for relief and rescue workers. Additionally, they can help to identify areas which are suitable for setting up aid camps where medical support and shelter can be provided to people.

Radar satellites are able to peer through clouds, which is an asset when weather conditions prevent the use of optical satellite instruments. Radar imagery can be used to identify hazards such as landslides that may be triggered by earthquakes. In the long term, radar data can also be processed to map surface deformations caused by earthquakes to help scientists understand better seismic events.

The Global Monitoring for Environment and Security’s SAFER project is collaborating with the Charter to provide a specialised capacity to produce damage maps over the area. SAFER’s value-adding providers SERTIT from Strasbourg and the German Aerospace Centre’s (DLR) centre for satellite-based crisis information (ZKI) from Munich are currently working on this.

In the framework of SAFER, other user organisations, including the German Federal Office of Civil Protection and Disaster Assistance and the UN World Food Programme, have requested damage-mapping services. Based on the collaboration between the Charter and SAFER, the first space-maps derived from crisis data acquired on 13 January were produced by SERTIT within 24 hours as rapid situation maps to help locate damaged areas with up-to-date cartographic material.


Together with ESA and CNES, the Charter, founded in 2000, currently has 10 members: the Canadian Space Agency (CSA), the Indian Space Research Organisation (ISRO), the US National Oceanic and Atmospheric Administration (NOAA), the Argentine Space Agency (CONAE), the Japan Aerospace Exploration Agency (JAXA), the British National Space Centre/Disaster Monitoring Constellation (BNSC/DMC), the U.S. Geological Survey (USGS) and the China National Space Administration (CNSA).

Via the Charter mechanism, all of these agencies have committed to provide free and unrestricted access to their space assets to support relief efforts in the immediate aftermath of a major disaster.

The Charter also collaborates with other satellite damage-mapping initiatives within the UN such as the UNITAR/UNOSAT team who is receiving support from the U.S. government to analyse satellite imagery to be provided to the Haitian government, UN sister agencies and NGOs.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
