Utilizing the Cloud to Modernize Delivery of Earthquake Information and Products
Description:
Following a federal government initiative to effectively adopt cloud resources in government agencies (https://cloud.cio.gov/strategy/), the U.S. Geological Survey’s (USGS) Geological Hazards Science Center (GHSC) began migrating resources from on-premises servers to the cloud. Over the last three years, developers at the GHSC have worked to design infrastructure that increases the security, stability, and efficiency of our systems. Through this improved infrastructure, we ensure that earthquake information is delivered in a consistent and timely manner.
In this presentation, we examine three different cloud systems that provide vital information about seismic events: 1) the product distribution layer (PDL), 2) the Ground Failure Product, and 3) the Sequence Product. PDL is a USGS platform that relays information about seismic events. The Ground Failure Product provides estimates of earthquake induced landslides and liquefaction. The Sequence Product is still under development and aims to provide information about how events are related by designating them as potential foreshocks, mainshocks, and aftershocks in an earthquake sequence. We will discuss how each of these systems posed a unique set of challenges that we considered when designing their individual cloud infrastructures. These challenges included but were not limited to designating resources to accommodate large numbers of requests following major earthquake events, run computationally expensive modelling code, and query large earthquake databases to dynamically generate up to date information. By examining these lessons learned, we hope that the wider seismic information community can be empowered to utilize the cloud for the delivery of earthquake information.
