Flooding and earthquakes are some of the most frequent natural hazards globally. A great deal of work has been done to understand their risk – but relatively little to determine how they can occur at the same time.
Last night at 11:41pm local time, the greater Melbourne region was shaken by a magnitude 4.0 earthquake – as calculated by the Seismology Research Centre – centred near Sunbury, approximately 30km north of the CBD.
This study proposed a new approach for rapidly estimating post-earthquake building loss with reasonable accuracy. Rapid estimation of post-earthquake building damage and loss is very important in urgent response efforts.
Sensors that detect changes in atmospheric pressure due to ground shaking can also obtain data about large earthquakes and explosions that exceed the upper limit of many seismometers, according to new research.
Remote sensing imagery is widely used in disaster response due to its easy accessibility and timeliness and can clearly reflect changes in features caused by earthquakes using pre- and post-earthquake image comparisons.
After Christchurch earthquakes, the engineering community was alarmed at the performance failures of modern buildings. One design initiative to come from the destruction and loss in New Zealand was to build structures with functional recovery in mind.
