February 13, 2020, the Merapi volcano in Indonesia and the Nevado del Ruiz volcano in Colombia erupted strongly.

The activity along the Ring of Fire isn’t decreasing at all.

Within the last 24 hours, it experienced a M7.0 earthquake in the Kuril Islands and at least two volcanoes in Indonesia and Colombia inundated the sky with plumes of ash and gas.

Merapi eruption – Indonesia

The most active volcano in Indonesia spewed ash and gases around 6,500 feet in the air at 5:16 a.m. local time.

The strong eruption lasted 150 seconds and ejected volcanic rocks across a 0.62-mile radius. Ashfall was reported in villages 6.2 miles south of the volcano.

Officials warn tourists and locals to stay outside a nearly two-mile radius from the peak on fire.

The volcanic activity of Merapi has been increasing since december 2019. Therefore violent eruptions similar to that of yesterday will happen in the future.

Eruption Nevado del Ruiz – Colombia

Plumes of ash and gas drifting 1,000 meters above the Nevado del Ruiz volcano were reported by the Geological Survey of Manizales / Colombia on February 13, 2020 at 10:25 am and 11:00 am.

A series of five earthquakes shook the state of Tennessee near the North Carolina border within a span of five hours.

The earthquakes hit the Eastern Tennessee Seismic Zone, one of the most active areas in the southeastern U.S.

The Southern Appalachian Seismic Zone, a seismic region stretching from northwestern Georgia, through Tennessee and into northeastern Alabama, was hit by a swarm of 5 earthquakes on February 11, 2020. The same area was struck by the seventh strongest quake in East Tennessee in more than a century on January 20, 2020.

The five tremors occurred within 5 hours. Four of them were clustered around Greenback and one hit near Sweetwater. They were all under M2.0:

  • M1.7 @ 2:48 a.m. EST, 3 miles east of Greenback
  • M1.4 @ 3:23 a.m. EST, 1.2 miles northeast of Greenback
  • M1.6 @ 4:11 a.m. EST, 1.9 miles northeast of Greenback
  • M1.3 @ 6:06 a.m., 1.9 miles east of Greenback
  • M1.6 @ 6:56 a.m. EST, 5 miles east of Sweetwater

Meanwhile, another M2.7 earthquake hit near Fincastle at 11:33 a.m. EST on February 12, 2020, which was reported by at least 40 people on the USGS homepage.

Eastern Tennessee Seismic Zone (ETSZ)

The Eastern Tennessee Seismic Zone (ETSZ) is one of the most active areas in the southeastern U.S. Its known faults are generally ancient and no known active faults reach the surface.

The largest earthquakes in the ETSZ are the M4.6 in 1973 near Knoxville, Tennessee and the M4.6 on April 29, 2003 near Fort Payne, Alabama.

However, the USGS has estimated that earthquakes as large as M7.5 are possible in the Southern Appalachian Seismic Zone.

The source of seismic activity in the Eastern Tennessee Seismic Zone remains a mystery.
