At 11,973 feet above sea level, Sierra Blanca is the tallest peak in the Sacramento Mountains, with spectacular views of the lower peaks and the Tularosa Basin. From the peak you can see where the black lava flows of Valley of Fire stops right before the dunes of White Sands begins. Stark contrast.

Most of the Sacramento Mountains are limestone. Sierra Blanca is the sole volcano.

The study indicates that ash from the #Nishinoshima #eruptions was transported by wind and #ocean currents to the waters around #Mukojima, serving as a nutrient source for #phytoplankton growth in that area.
The findings suggest that volcanic ash can enhance the productivity of #marine waters even at considerable distances from the #volcanic site.

“Highlights:
• A novel method for detecting geothermal components from solar energy dominated LST.
• Using LST time series to eliminate temporal variant solar energy input.
• Uncertainty in anomaly identification quantified by probability measure.
• Capable of revealing LST anomalies caused by geothermal, anthropogenic and surface processes..."

Melting #Antarctic ice sheets may be causing larger volcanic eruptions

During #deglaciation, melting of kilometers-thick #IceSheets reduces the mass weighing down the land, which leads to #uplift. This alters the pressure inside #magma chambers lying below the Earth's surface, causing #volcanic eruptions.

I love a good #maar #volcano sequence.

A few shots of our work at the Estrada rhyolitic maar, one of the >10 #volcanic craters around the city of Kamembarhu, Kuanhasï juata (Mexico). These spectacular layers of pulverized bedrock and ashfall--exposed at a quarry--are the result of explosions caused by ascending #magma intruding into near-surface water reservoirs (in this case, shallow lakes). We call these types of events #phreatic eruptions. Note excavator for scale.
