08FORCE Raknes Automated seismic interpretation using machine learning and field interpretations
Espen B. Raknes, Aker BP, espen.birger.raknes@akerbp.com June 13, 2018 Seismic interpretation is dependent on the experience of the interpreter and the quality of the seismic data. Therefore, interpretations include uncertainties, in particular in areas with complex geology.

AI Can Save You From An Earthquake
Physicist and author Louis A. Del Monte discusses a recently published finding that indicates artificial intelligence can save you from an earthquake. The new finding, recently published in Science Advances, indicates that AI is capable of detecting 17 times more earthquakes than older methods in a fraction of the time. There’s even some hope that it could predict earthquakes before they occur. This could be done by looking for patterns in the data; for example, finding times when a number of small earthquakes have happened in quick succession, triggering a bigger, potentially damaging quake. In addition to describing the new finding, Lou explains the Richter magnitude scale (often shortened to Richter scale), which is the most common standard of measurement for earthquakes. It was invented in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake.

Machine learning accurately predicts slow slip in earthquakes
Machine-learning research has detected seismic signals accurately predicting the slow slipping of the Cascadia fault. It has also found similar signals predicting slow slip failure in Chile and New Zealand. Los Alamos National Laboratory researchers applied machine learning to analyze 12 years of historic Cascadia data. Cascadia’s constant tremors produce an acoustic signal, like sound waves. The key to Cascadia’s behavior was buried in that acoustic data

Why are earthquakes so hard to predict? - Jean-Baptiste P. Koehl
Take a look at the theories behind why earthquakes occur, what makes them so hard to predict and the warning system technologies we rely on today. In 132 CE, Zhang Heng presented his latest invention: a large vase he claimed could tell them whenever an earthquake occurred for hundreds of miles. Today, we no longer rely on pots as warning systems, but earthquakes still offer challenges to those trying to track them. Why are earthquakes so hard to anticipate, and how could we get better at predicting them? Jean-Baptiste P. Koehl investigates. Lesson by Jean-Baptiste P. Koehl, directed by Cabong Studios.

Data mining digs up hidden clues to major California earthquake triggers
A powerful computational study of southern California identified 10 times more earthquakes occurred, and 10 times more frequently than previously measured. Researchers were able to detect, understand, and locate quakes more precisely, and they created the most comprehensive earthquake catalog to date. The big data analysis of the entire region also revealed new information, such as triggering mechanisms and hidden foreshocks, which may help predict larger quakes.

Richter's predictor Modelling Earthquake Damage
In this research the basic motto is “Prediction of earthquake damage using Machine Learning” and the idea is to use existing data set of seismic activity for training and then to predict, when an earthquake will happen and how much damage will be use through it. In this study, we are using Random forest classifier for the implementation.

Kaggle: Earthquake Prediction Challenge
Forecasting earthquakes is one of the most important problems in Earth science because of their devastating consequences. Current scientific studies related to earthquake forecasting focus on three key points: when the event will occur, where it will occur, and how large it will be. In this competition, you will address when the earthquake will take place. Specifically, you’ll predict the time remaining before laboratory earthquakes occur from real-time seismic data. If this challenge is solved and the physics are ultimately shown to scale from the laboratory to the field, researchers will have the potential to improve earthquake hazard assessments that could save lives and billions of dollars in infrastructure. This challenge is hosted by Los Alamos National Laboratory which enhances national security by ensuring the safety of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.

Siraj Raval's
Data Science coding challenge time! The popular Data Science competition website Kaggle has an ongoing competition to solve the problem of earthquake prediction. Given a dataset of seismographic activity from a laboratory simulation, participants are asked to create a predictive model for earthquakes. In this video, I'll attempt the challenge as a way to teach 3 concepts; the Data Science mindset, Categorical Boosting, and Support Vector Regression (SVR) models. I'll be coding this using Python from start to finish in the online Google Colaboratory environment. The credits are from a mix of different Kaggle Kernels that I liked (lots), as well as my own code + explanations.This is the code for the Kaggle Earthquake Challenge videp | Siraj Raval on YouTube...
