Predicting earthquakes using ionospheric total electron content anomalies- study

A new study published recently in Remote Sensing proposes the implementation of machine learning support vector machine (SVM) technique, applied with GPS ionospheric total electron content (TEC) pre-processed time series estimations, to evaluate potential precursors caused by earthquakes.

Mysterious global tsunami in 2021 caused by hidden M8.2 earthquake

Mysterious global tsunami in 2021 caused by hidden M8.2 earthquake

Scientists have uncovered the source of a mysterious 2021 tsunami that sent waves around the globe in August 2021 when a magnitude 7.5 earthquake hit near the South Sandwich Islands. The epicenter was 47 km (29 miles) below the Earth’s surface — too deep…

World’s longest recorded earthquake lasted for 32 years

World’s longest recorded earthquake lasted for 32 years

The devastating M8.5 earthquake that shook Sumatra, Indonesia, in 1861 was long believed to be a sudden rupture on a previously quiescent fault. However, new research showed that tectonic plates below the island had been slowly crashing against each other for 32…

Study reveals inner workings of slow-slip earthquakes

Study reveals inner workings of slow-slip earthquakes

Slow-slip earthquakes have been detected at many earthquake hotspots in the world, including areas around the Pacific Ring of Fire, but it remains unclear as to how they are linked to the damaging quakes that take place there. In a new study, researchers at The…

Electromagnetic anomalies occurring before large earthquakes

Electromagnetic anomalies occurring before large earthquakes

A new study published in Earth, Planets and Space sheds new light on the electromagnetic anomalies occurring before large earthquakes. The research supports the hypothesis that fault rupture progresses just before an earthquake, and the invading gas is charged and…

Study reveals mechanism of naturally occurring ‘earthquake gate’

Study reveals mechanism of naturally occurring ‘earthquake gate’

A new study reveals the workings of an "earthquake gate" — a naturally occurring blocker that decides which quakes are allowed to grow into M8.0 or greater. "An earthquake gate is like someone directing traffic at a one-lane construction zone,"…

New technology detects long-hidden earthquakes

New technology detects long-hidden earthquakes

Scientists at the Stanford School of Earth, Energy, and Environmental Sciences described a new method for using artificial intelligence to detect millions of long-hidden small earthquakes or microquakes, providing possible hints about how earthquakes evolve. Big…
