Plumes From Earth’s Mantle Could Cause Supervolcano Eruptions, Continental Breakdown
“This instability can have a lot of implications for the surface tectonics, and also earthquakes and supervolcanic eruptions…” by Andrei Dergalin via Sputniknews Image: CC BY-SA 2.0 / Argonne National Laboratory / Composition of Earth’s mantle The new research suggests that the two large low-shear-velocity provinces, located beneath Africa and the Pacific respectively, differ in how close to the surface … Continue reading

Oklahoma Hit by 7 Earthquakes in 24 Hours
In just less than 24 hours, seven earthquakes rattled across Oklahoma, according to data from the United States Geological Survey. The temblors ranged in intensity from magnitude to 1.6 to 2.5. The first quake — measuring at magnitude 1.9 — struck at 10:44 a.m. Sunday roughly 2.5 miles south of Perry, the USGS reported. The second quake — magnitude 1.7 … Continue reading
Strange Seismic Waves Picked up Circling the Earth on November 11, Seismologists Stumped
Feel any strange vibrations on November 11? A deep thrum rippled around the world — lingering a whole 20 minutes. It wasn’t an earthquake. Nobody knows what it was. Seismic sensors first picked up the event originating near an island between Madagascar and Africa. Then, alarm bells started ringing as far away as Chile, New Zealand and Canada. Hawaii, almost … Continue reading
4.5M Earthquake Near San Andreas Fault a Reminder of it’s Potentially Devastating Power
With scientist warning of an increase in large earthquakes this year due to a slow in Earths rotation and geological activity going on in Hawaii one has to take these events a little more seriously. via LA Times: A magnitude 4.5 earthquake shook a large portion of Southern California on Tuesday, and was felt from San Diego to Santa Clarita, … Continue reading
7.5 Magnitude Quake Hits Papua New Guinea
The 7.5 magnitude earthquake struck the heart of the island near the near the Southern Highlands area, with tremors felt across the nearby region. The phenomenon hit at a depth of 10km at roughly 4am local time (6pm GMT). It is currently unclea rif any damage or injuries were cause by the substantial siesmic event. Papua New Ginuea rests on … Continue reading
Ring of Fire Hit by String of Quakes and Volcanic Eruptions – At Least 5 Events in 2 Days
Well I hate to say it but I think the scientist who warned that we would be seeing an increase in larger earthquakes this year due to Earth’s rotation slowdown might be right. Also note worthy, this scientist William Yeck of the USGS seems to think none of the activity as of late are connected, well none of us can … Continue reading
Scientist Blame Earthquake Uptick in Texas on Fracking, Awakening Sleeping Faults
In the US since 2008, an unprecedented surge in the amount of earthquakes has hit several states. Most scientists now agree the surge is being triggered by fracking, or wastewater injections being shot into deep wells for oil and gas production. A paper describing the reasons for an uptick in earthquakes occurring in states like Texas was published on Friday … Continue reading
Study Shows Shifting Water Weight Can Trigger Small Earthquakes in California
Water shapes California powerfully, deluging the state with El Niño – generated rainfalls and drying it out with punishing droughts. Now, a new study suggests that water may play yet another role: triggering earthquakes. Scientists for decades have tried to understand how different natural forces, pressing on Earth’s surface, might help explain changes in earthquake rates, with mixed results. The … Continue reading
Central Italy Hit by More than 65,500 Earthquakes Within 9 Months
More than 65,500 earthquakes have hit Central Italy within nine months. And it is not close to stop: 100 and 150 tremors shake the region on average each day. The seismic sequence that currently hits central Italy began in August 2016. According to INGV (Istituto Nazionale di Geofisica e Vulcanologia), it continues to be extremely active with more than hundred … Continue reading
