DeepShake uses machine learning to quickly estimate the intensity of an earthquake’s vibration

A deep spatiotemporal neural network trained on more than 36,000 earthquakes offers a new way to quickly predict the intensity of Earth’s shaking once an earthquake strikes, researchers report at the 2021 SSA annual meeting.

The DeepShake system analyzes seismic signals in real time and issues an advanced strong vibration warning based on the characteristics of the early waves detected from the earthquake.

DeepShake was developed by Daniel J. Wu, Avoy Datta, Weiqiang Zhu, and William Ellsworth at Stanford University.

The earthquake data used to train the DeepShake network came from seismic recordings of the Ridgecrest, California 2019 sequence. When its developers tested DeepShake’s potential using the actual vibration of the Ridgecrest magnitude 7.1 earthquake on July 5, the neural network sent simulated alerts between 7 and 13 seconds before the ground shaking arrived HD to locations in the Ridgecrest area.

The authors emphasized the novelty of using deep learning for rapid early warning and direct prediction from seismic records alone. “DeepShake is able to capture signals in seismic waveforms across space and time dimensions,” Datta explained.

He added that DeepShake demonstrates the potential of machine learning models to improve the speed and accuracy of earthquake warning systems.

“DeepShake aims to improve earthquake early warnings by making vibration estimates directly from ground motion observations, eliminating some of the intermediate steps used by traditional warning systems,” Wu said.

Wu explained that many early warning systems first determine the location and magnitude of the earthquake, and then calculate the ground motion of the site based on the equations for predicting the ground movement.

He added, “Each of these steps could lead to an error that could weaken the expectations of the earth’s shaking.”

To address this, the DeepShake team turned to a neural network approach. The series of algorithms that make up a neural network are trained without the researcher identifying the “important” signals for the network to use in its predictions. The network learns the features that optimally predict the strength of the future vibration directly from the data.

“We have noticed by building other neural networks for use in seismology that they can learn all sorts of interesting things, and thus they may not need the epicenter and size of the earthquake to predict well,” Wu said. “DeepShake is being trained on a pre-defined network of seismic stations, so that the local characteristics of those seismic stations become part of the training data.”

“When training a machine learning model from start to finish, we really believe that these models are able to utilize this additional information to improve accuracy,” he said.

Wu, Datta, and colleagues view DeepShake as a complement to operational ShakeAlert in California, adding to its earthquake early warning systems toolkit. Data added, “We are really excited to expand DeepShake beyond Ridgecrest, and enhance our work for the real world, including failures such as broken terminals and high network latency.”

What Are The Main Benefits Of Comparing Car Insurance Quotes Online

LOS ANGELES, CA / ACCESSWIRE / June 24, 2020, / Compare-autoinsurance.Org has launched a new blog post that presents the main benefits of comparing multiple car insurance quotes. For more info and free online quotes, please visit https://compare-autoinsurance.Org/the-advantages-of-comparing-prices-with-car-insurance-quotes-online/ The modern society has numerous technological advantages. One important advantage is the speed at which information is sent and received. With the help of the internet, the shopping habits of many persons have drastically changed. The car insurance industry hasn't remained untouched by these changes. On the internet, drivers can compare insurance prices and find out which sellers have the best offers. View photos The advantages of comparing online car insurance quotes are the following: Online quotes can be obtained from anywhere and at any time. Unlike physical insurance agencies, websites don't have a specific schedule and they are available at any time. Drivers that have busy working schedules, can compare quotes from anywhere and at any time, even at midnight. Multiple choices. Almost all insurance providers, no matter if they are well-known brands or just local insurers, have an online presence. Online quotes will allow policyholders the chance to discover multiple insurance companies and check their prices. Drivers are no longer required to get quotes from just a few known insurance companies. Also, local and regional insurers can provide lower insurance rates for the same services. Accurate insurance estimates. Online quotes can only be accurate if the customers provide accurate and real info about their car models and driving history. Lying about past driving incidents can make the price estimates to be lower, but when dealing with an insurance company lying to them is useless. Usually, insurance companies will do research about a potential customer before granting him coverage. Online quotes can be sorted easily. Although drivers are recommended to not choose a policy just based on its price, drivers can easily sort quotes by insurance price. Using brokerage websites will allow drivers to get quotes from multiple insurers, thus making the comparison faster and easier. For additional info, money-saving tips, and free car insurance quotes, visit https://compare-autoinsurance.Org/ Compare-autoinsurance.Org is an online provider of life, home, health, and auto insurance quotes. This website is unique because it does not simply stick to one kind of insurance provider, but brings the clients the best deals from many different online insurance carriers. In this way, clients have access to offers from multiple carriers all in one place: this website.
