Rapid Delivery of Earthquake Catalog With Azure

Description: 

There is a critical need for emergency service providers to receive rapid earthquake information during an emerging earthquake sequence. To that end, we designed a cloud-based system to deliver an earthquake catalog and related products based on web services. In this presentation, we discuss how we implemented this system for the California Geological Survey (partially funded by the California Office of Emergency Services) using Microsoft’s cloud computing platform Azure. System requirements were low latency, high availability, real-time data delivery, and security. The source of the data is the USGS Product Distribution Layer.  The system’s end users are emergency service providers and the public.

The cloud-based delivery system is deployed in Azure and uses a complement of services to accomplish a multitude of functionalities. Key services include Kubernetes, serverless functions, push notifications, content delivery networks, container registries, storage, databases, maps, and active directory. The back end system is responsible for all data collection, storage, and distribution. The front end is a single-page application that requests a one-week earthquake catalog and receives real-time updates via push notifications. The single-page application’s use of reactive components and responsive web design efficiently present the data to a large audience of users and devices. Management tools facilitate system monitoring and updates as needed.
