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.

Eruption In Progress At Kamchatkan Volcano Making The Winter Cold Much Worse

Kamchatkan eruption from space – NASA

A relatively large explosive eruption started January 21, 2014 and is currently in progress at Kamchatkan Shiveluch volcano, Russia. But this isn’t anything new.

This ash plume rose to estimated 4.5 – 5 km (14, 760-16, 400 ft) altitude and is drifting west. The ash is thickening the atmosphere, and is exacerbating the heavy winter cold air and blizzard conditions impacting the Northern Hemisphere.

The volcano continues to produce intense degassing and ash venting. Glow from the active lava dome is visible on night-time webcam images.

When this much ash remains in the atmosphere and is circulated in the wind currents, you will have a drop in temperature and cooling.

Activation code is now orange.

Here is a slide show of the eruptions at Kamchatkan in January 2014 and December 2013 from NASA Terra/MODIS images and images from the Institute of Volcanology and Seismology FEB RAS, KVERT
