The details
Satellites are playing a pivotal role in the response to a magnitude 6.8 earthquake in Morocco.
The use of satellite imagery and advanced analysis techniques is enabling responders to efficiently reach affected towns and villages in the High Atlas mountains.
These tools are also helping to assess damage to infrastructure, identify blocked routes caused by landslides, and gather valuable insights about the earthquake.
Satellites are being used to create rapid maps of Morocco in the aftermath of the earthquake.
The data gathered from these satellites is assisting relief workers in accessing the affected areas in the High Atlas mountains.
Satellite imagery is providing valuable information about the extent of damage to infrastructure, such as buildings, roads, and bridges.
Relief workers are using satellite data to identify blocked routes caused by landslides.
Advanced analysis techniques, including interferometry, are being utilized to examine elevation changes and compare “before” and “after” views of the affected areas.
The European Union’s Sentinel-1a satellite has provided observations for creating ground movement maps.
The Sentinel-1a satellite carries a radar instrument capable of sensing the ground in all weather conditions.
The analysis of satellite data confirms that the earthquake was caused by a north-dipping buried thrust fault.
Ground movement towards the satellite reached a maximum of 15cm, with a drop of approximately 10cm.
This analysis will assist scientists in understanding the nature of the earthquake and assessing future hazard risks.
The earthquake affected an area that had not experienced a major quake in a long time.
Previously, geologists would have had to physically inspect the ground to gather the same level of information.
The UK Centre for Observation and Modelling of Earthquakes, Volcanoes, and Tectonics (Comet) has automated this analysis process.
The UK’s recent rejoining of the EU’s Copernicus Earth observation system allows British scientists to take up leadership roles in satellite development.
The use of satellite imagery and advanced analysis techniques has proven instrumental in responding to the earthquake in Morocco.
By rapidly mapping the affected areas and providing detailed insights into the infrastructure damage and ground movement, satellites have significantly aided relief workers and scientists in understanding the earthquake’s characteristics.
The automated analysis process implemented by the UK’s Comet, coupled with the country’s renewed participation in the Copernicus Earth observation system, highlights the importance of international collaboration in satellite development and disaster response efforts.
This collaboration is crucial in assessing future hazard risks.
