2013 marks record year for the number of volcanoes erupting across the planet (29 already for 2014)

December 5, 2013 – GEOLOGY – This year will go down on record, as seeing the most volcanic eruptions recorded in modern history. The previous number was set in 2010, at 82 volcanic eruptions for the year. The number of volcanoes erupting across the planet has been steadily rising from a meager number of just 55 recorded in 1990. While most scientists may readily dismiss any significance to the latest figures and may be quick to say the planet is just experiencing normal geological activity, it does raise other concerns about just what may be transpiring within the interior of our planet. The average number of volcanic eruptions per year should be about 50 to 60; as of December 5, 2013, we already at 83. Volcanic eruptions are one way the planet dissipates a dangerous build-up of heat, magma, and pressurized gases. The planet’s outer core is thought to flirt with critical temperatures in the range of around 4400 °C (8000 °F). Any rise or major fluctuation in interior gradient could have profound and disruptive effects on processes whose very properties are government by convective heat emanating from the planet’s outer core: magnetic field propagation, tectonic plate movements, sea-floor spreading mechanics, and mantle plume activity. Mantle plumes or hotspots are thought to be the central mechanism which fuels the vast underground chambers of many of the world’s supervolcanoes. –The Extinction Protocol

29: Ubinas Volcano emits ash, smoke: shaken by violent spasm of tremors

February 5, 2014PERUThe Ubinas Volcano near the southern city of Arequipa in Peru has become active again after several months of minimal activity. According to El Comercio, the volcano is emitting columns made of ash, smoke, and steam, as well as registering seismic movements. Since Jan. 31, the volcano has reportedly experienced as many as 100 seismic events every day, including a Feb. 1 movement which lasted for seven hours. El Comercio reports that the various ash columns released by the volcano have reached heights from 700 to 2,000 meters. The volcano’s recent activity has been attributed to water seeping into the crater. When the water comes into contact with magma, the it turns into steam, which then creates pressure inside the crater. This pressure is what causes the volcano to expel ash. No damages have been reported as a result of the volcano’s most recent activity. A series of similar explosions in September created health problems for many local residents, some of whom suffered from headaches and gastrointestinal problems after breathing the silicon ash released by Ubinas. The Ubinas Volcano, located in the Moquegua region 70 kilometers outside of Arequipa, has displayed a sudden burst of activity. Prior to the September eruptions, the volcano had been dormant since 2009. –Peru this Week
