Earth Changes: Second Earthquake Swarm In Two Months Taking Place In California

Nearly 20 'micro-quakes' hit near the Salton SeaA series of small earthquakes struck near the Salton Sea area overnight.
Nearly 20 micro-quakes — the strongest measuring magnitude 3.3, with others much smaller — struck the town of Niland near the eastern shore of the Salton Sea, according to the U.S. Geological Survey. A magnitude 3.6 quake was recorded near Salton City on the west side of the Salton Sea.
In September, a series of more than 200 small quakes hit the area. That prompted scientists to say for several days that there was an elevated risk for a big San Andreas fault earthquake. Many of the minor quakes were located under the sea itself.
The Salton Sea is one of California’s most seismically complex areas. It is located on a web of faults that scientists fear could one day wake up the nearby San Andreas from its long slumber.
The Sinabung volcano erupted strongly in Indonesia on November 1, 2016.
And during the explosion some tornado-like vortices formed and amazed many witnesses and photographers.
Now technically these aren’t tornadoes, even if they look like it. Tornadoes are when a funnel cloud is connected to the ground at its bottom and the base of a cumulonimbus cloud at its top. They form from the top down, dropping from the cloud base.
In this case, though, the phenomena are built from the ground up. The pyroclastic flow heats the air over the ground, causing it to rise. Air from the sides then rushes in to fill the partial vacuum. This creates swirls, which can get amplified into the vortices. This makes these events more like a dust devil than proper tornadoes. Or, I suppose, an ash devil.
Remember, that’s not just smoke you’re seeing; it’s vaporized rock, millions of tons of it! And it’s superheated to glowing, which can then flow downhill at hundreds of kilometers per hour, laying waste to whatever it touches.
Like I said, terrifying. Amazingly, though, volcanologists are getting better at predicting these. Magma moving underground can cause tremors that indicate an explosive eruption is imminent, allowing people to be evacuated… Sometimes.
There is a terrible beauty to volcano eruptions (much like hurricanes seen from space) that belies their destructive power. This video features a pyroclastic flow and ash devils at Sinabung in February 2014:
