Venezuela despierta hoy, bajo un Milagro de Dios. El Terremoto de 7.3 grados pudo haber sido devastador Su profundidad fue de 123 km según la USGS, lo que evitó q en una Venezuela tan vulnerable en su estructura, ocurriera una gran catástrofe y un posible Tsunami.

Penn State geologist Barry Voight — brother of actor Jon — has sketched an eruption scenario in a report that lands today in Vancouver.

An expert on landslides, Voight was asked in April by
USGS’s Rocky Crandall to provide analysis on the north face bulge.

Esta 'pequeña' esfera celeste representa absolutamente toda el agua que existe en nuestro planeta. El agua de los océanos, lagos, ríos, subterránea y hasta de la atmósfera y los casquetes polares.

#MountStHelens 1980: Small bursts of steam & ash continue. Scientists believe a major eruption would be preceded by changes in seismicity or rate of bulging. They are uneasy, watching/tracking the volcano closely; hoping to provide adequate warning. #VolcanoAwarenessMonth

St. Helens remains quiet — no eruptions since the 14th, but quakes and bulging continue. After flying around the mountain earlier, David Johnston of the USGS admits to the Daily News he “practically fell asleep in the helicopter.”

Privately, Dave tells his

Earth’s waterways and oceans are awash with microplastics. The USGS has a strategic science vision for documenting #microplastics and for prioritizing research to mitigate the impact on the environment and human society. pubs.usgs.gov/publication/ci… .

Check out this stunt by Dan Perkins on top of Utah's 106' tall Owachomo Bridge! It's the thinnest of the three natural bridges in Natural Bridges Nat'l Monument.

#DKY Owachomo means 'rock mound' in Hopi?

Now get off your high horse, Dan, and don't try this again.🐴

A team of scientists, including from Astrogeology, joined forces with #NASA to explore the planetary realm! At Bruneau Dunes State Park in Idaho, the group used a lander concept to observe interactions between the atmosphere and surfaces. Learn more: eos.org/science-update…

The snow might not have been on time, but the recap is on beat.

Digging a little deeper into Kīlauea’s 1924 eruptions and their impacts on communities is the focus of this week’s #VolcanoWatch : usgs.gov/observatories/…

May is #VolcanoAwarenessMonth in WA. Today, meet #MountStHelens , a site of continuous geologic change. Landslides tear the volcano apart while lava flows & domes work to rebuilt it. Large explosive eruptions blanketed the PNW with ash, lahars swept down valleys for tens of miles.
