Hidden Microearthquakes Illuminate Large Earthquake-Hosting Faults in Oklahoma and Kansas

The central United States has experienced a significant increase in the number of earthquakes over the past decade. Oklahoma and Kansas have been particularly affected, with both states experiencing a surge in earthquake activity. Scientists have been studying this phenomenon to better understand the underlying causes of these earthquakes. Recent research has revealed that hidden microearthquakes can illuminate large earthquake-hosting faults in Oklahoma and Kansas.

Introduction

The central United States has experienced a significant increase in the number of earthquakes over the past decade. This surge in earthquake activity has been linked to human activities such as wastewater injection from oil and gas operations. However, scientists are still trying to understand the underlying causes of these earthquakes.

The Study

A recent study published in the journal Geophysical Research Letters sheds new light on this phenomenon. The study was conducted by researchers from the University of Oklahoma, the U.S. Geological Survey, and other institutions. The researchers used a technique called "template matching" to identify hidden microearthquakes that occurred before and after larger earthquakes.

What are Microearthquakes?

Microearthquakes are small earthquakes that occur at depths of less than 10 kilometers. They are too small to be felt by humans but can be detected by seismometers. These earthquakes are important because they can provide valuable information about the structure and behavior of faults.

How Do Microearthquakes Illuminate Large Earthquake-Hosting Faults?

The researchers found that hidden microearthquakes can illuminate large earthquake-hosting faults in Oklahoma and Kansas. By analyzing these microearthquakes, they were able to identify previously unknown faults that could potentially host larger earthquakes.

Implications for Earthquake Hazard Assessment

This research has important implications for earthquake hazard assessment in Oklahoma and Kansas. By identifying previously unknown faults, scientists can better understand the potential for larger earthquakes in these regions. This information can be used to develop more accurate earthquake hazard maps and to inform emergency preparedness efforts.

Conclusion

The surge in earthquake activity in Oklahoma and Kansas has been a cause for concern in recent years. However, new research has revealed that hidden microearthquakes can provide valuable information about the underlying causes of these earthquakes. By analyzing these microearthquakes, scientists can better understand the structure and behavior of faults in these regions. This information can be used to develop more accurate earthquake hazard maps and to inform emergency preparedness efforts.
