High-quality ground motion records are required for engineering applications including response history analysis, seismic hazard development, and validation of physics-based ground motion simulations. However, the determination of whether a ground motion record is high-quality is poorly handled by automation with mathematical functions and can become prohibitive if done manually. Machine learning applications are well-suited to this problem, and a previous feed-forward neural network was developed (Bellagamba et al. 2019) to determine high-quality records from small crustal events in the Canterbury and Wellington regions for simulation validation. This prior work was however limited by the omission of moderate-to-large magnitude events and those from other tectonic environments, as well as a lack of explicit determination of the minimum usable frequency of the ground motion. To address these shortcomings, an updated neural network was developed to predict the quality of ground motion records for all magnitudes and all tectonic sources—active shallow crustal, subduction intraslab, and subduction interface—in New Zealand. The predictive performance of the previous feed-forward neural network was matched by the neural network in the domain of small crustal records, and this level of predictive performance is now extended to all source magnitudes and types in New Zealand making the neural network applicable to global ground motion databases. Furthermore, the neural network provides quality and minimum usable frequency predictions for each of the three orthogonal components of a record which may then be mapped into a binary quality decision or otherwise applied as desired. This framework provides flexibility for the end user to predict high-quality records with various acceptability thresholds allowing for this neural network to be used in a range of applications.
Shows the face of a man with a large tear rolling down his cheek ; in the tear is the word 'Christchurch'. Context - On 22 February 2011 at 12:51 pm (NZDT), Christchurch experienced a major magnitude 6.3 earthquake, which resulted in severe damage and many casualties. A National State of Emergency has been declared. This followed on from an original magnitude 7.1 earthquake on 4 September 2010 which did far less damage and in which no-one died.

Six years after Christchurch's destructive 6.3 magnitude earthquake the rebuild programme is now being used to provide training for workers from the Pacific. Twenty-four workers from Fiji, Tonga and Samoa are helping rebuild the city while learning new skills and earning money they can send home.
Geologists say the South Island is likely to be hit with another, even larger, earthquake sometime in the next 50 years. Teams of earthquake experts are in Canterbury studying the previously undetected fault responsible for Saturday's 7.1 magnitude earthquake and dozens of aftershocks.
Monday marks a decade since a 6.2 magnitude quake close to the centre of Christchurch killed 185 people. Everybody in the city that day has a story to tell and for many, the memories remain fresh, ten years on. Conan Young has been speaking to some of them.
