Large devastating events in systems such as earthquakes, typhoons, market crashes, electricity grid blackouts, floods, droughts, wars and conflicts, and landslides can be unexpected and devastating. Events in many of these systems display frequency-size statistics that are power laws. Previously, we presented a new method for calculating probabilities for large events in systems such as these. This method counts the number of small events since the last large event and then converts this count… Expand

Nowcasting Great Global Earthquake and Tsunami Sources
Nowcasting refers to the use of proxy data to estimate the current dynamic state of driven complex systems such as earthquakes, neural networks, or the financial markets. In previous papers, methodsExpand
The complex dynamics of earthquake fault systems: new approaches to forecasting and nowcasting of earthquakes
TLDR
The focus is on anticipating the earthquake rupture before it occurs, rather than characterizing it rapidly just after it occurring, and new types of data, models, and computational power may provide avenues for progress using machine learning that were not previously available. Expand
Nowcasting earthquakes in Sulawesi Island, Indonesia
Large devastating events such as earthquakes often display frequency–magnitude statistics that exhibit power-law distribution. In this study, we implement a recently developed method calledExpand
Natural Time, Nowcasting and the Physics of Earthquakes: Estimation of Seismic Risk to Global Megacities
Natural Time (“NT”) refers to the concept of using small earthquake counts, for example of M > 3 events, to mark the intervals between large earthquakes, for example M > 6 events. The term was firstExpand

Statistical quantification of observed seismicity is important for understanding earthquake dynamics and future risk in any seismic-prone region. In this paper, we implement the idea of nowcastingExpand
Natural Time and Nowcasting Earthquakes: Are Large Global Earthquakes Temporally Clustered?
The objective of this paper is to analyze the temporal clustering of large global earthquakes with respect to natural time, or interevent count, as opposed to regular clock time. To do this, we useExpand
Contemporary Earthquake Hazards in the West-Northwest Himalaya: A Statistical Perspective through Natural Times
Himalayan earthquakes have deep societal and economic impact. In this article, we implement a surrogate method of nowcasting (Rundle et al., 2016) to determine the current state of seismic hazardExpand
Case Study of Earthquake Probability Using Natural Time and Nowcasting of the Sarpol-e Zahab Region in Kermanshah, Iran
The observed statistical seismic quantity is critical to understanding the nature of earthquakes and potential hazards in earthquake-prone areas. We have studied the nowcasting concept, whichExpand
Global Seismic Nowcasting With Shannon Information Entropy
TLDR
This first application of seismic information entropy finds that the earthquake potential score values are similar to the values using only natural time, however, other characteristics of earthquake sequences, including the interevent time intervals, or the departure of higher magnitude events from the magnitude‐frequency scaling line, may contain additional information.

A synoptic view of the natural time distribution and contemporary earthquake hazards in Sumatra, Indonesia

Abstract—There is growing evidence that some proportion of large and great earthquakes are preceded by a period of accelerating seismic activity of moderate-sized earthquakes. These moderateExpand

An earthquake alters the shear and normal stress on surrounding faults. New evidence strengthens the hypothesis that such small, sudden stress changes cause large changes in seismicity rate. RatesExpand
