Activity Intense At Tungurhua Volcano

Activity increases at Ecuador’s Tungurhua volcano.

Tungurhua volcano in Ecuador continues to be very active with frequent explosions ejecting lava and ash plumes several hundred feet up to 3-4 km (2+ miles) above the summit.

Strong shock waves and cannon-shot explosion sounds are accompanying the eruptions. Ash fall occurred in the towns and villages of Pondoa, Runtún, Triunfo, and Río Verde.

Two More To Watch

Peru’s Ubinas volcano is having new eruptions, and San Miguel volcano in El Salvador is showing signs of another eruption.

Tungurhua

Tungurahua is one of South America’s most active volcanoes. Since 2000, a new lava dome has been growing in its summit crater.

Tungurahua’s activity has been characterized by frequent powerful ash explosions, producing ash plumes of several kilometers high, as well as dangerous pyroclastic flows. Part of the population around its base has been evacuated, and people in villages living at lower elevations are on high alert.

Costa Rica Experiencing Quakes; Will More Follow?

Central America is experiencing more large earthquakes.

The entire western edge of  Central and South American is experiencing large earthquakes, but when one of my favorite countries, Costa Rica, has a large earthquake, I always post it.

On February 12, 2014, offshore Joco, Costa Rica had a 4.7 magnitude quake. This quake occurred amid a string of quakes sriking the western portion of both Central and South America:

  1. 4.6  Chile
  2. 4.6   Argentina
  3. 5.5  Chile
  4. 5.2  Chile
  5. 4.5  Guatemala
  6. 4.7  Costa Rica

Now, compare this activity to the volcanic activity in these countries. Connect the dots to see the increase in both volcanic and earthquake activity in Central and South America.

A Hot Volcanic Line-Up

Volcanic activity continues to increase on the planet.

Things are heating up out there, with volcanoes, I mean. Add these eruptions to the current list of active volcanoes:

  1. San Miguel, El Salvador
  2. Tungurahua, Ecuador
  3. San Cristobal, Nicaragua
  4. Shishaldin, Bering Strait (Alaska)
  5. Kelut, Southern Indonesia
  6. Karangetang (Api Siau), Indonesia
  7. Barren Island, Indian Ocean
  8. Asosan, Japan

What Does This Mean?

An increase in volcanic eruptions means more earthquake activity in these regions. And, as more ash and steam circulate into the upper atmosphere, this also means global wind currents will be filled with particulate matter.

And, this means global shifts in the climate – more storms, and global cooling.
