The mountain's largest feature is the Valle del Bove (Valley of the Ox) a large horseshoe-shaped caldera on the eastern slope.
The eruption which removed the upper 1300 feet (396 meters) of the summit left a horseshoe-shaped crater and a barren wasteland.

With a weak field this shielding is less efficient. The charged particles bombarding Earth's atmosphere during solar storms would punch holes in Earth's atmosphere
During a field reversal this protective magnetic shield is going to be weak and might even disappear for a century or more.
Without our magnetic shield those solar particles might create havoc with the weather. That cosmic radiation blasting the Earth's surface could cause genetic mutations and cancers.
but the fact remains for the past 300 years Earth s magnetic field solar shield has been reducing.
A highly conducting material shields out external magnetic disturbances. One thing about reversals. They seem to happen rapidly
magnetic field generated deep within the planet is a shield against particle radiation from space. In the South Atlantic this shield is much weaker than elsewhere across the globe
and radiation from space therefore penetrates deeper into the atmosphere. This region is known as the South Atlantic Anomaly (SAA)
The only thing stopping Earth having a lifeless environment like Mars is the magnetic field that shields us from deadly solar radiation

#Compound derived from vegetables shields rodents from lethal radiation dosesgeorgetown University Medical center researchers say a compound derived from cruciferous vegetable such as cabbage cauliflower and broccoli protected rats and mice from lethal doses of radiation.
Their faces are broad shields the eyes reduced to tiny points at the edges and the fierce jaws bristling with sharp teeth.
and games over the course of a single season the researchers employed sensors in the helmets of 50 players on three teams in two different leagues.
The sensors were installed on an elastic base inside the helmet so that they remained in contact with the head throughout the duration of head impact allowing for measurement of head acceleration rather than that of the helmet.
Data from the sensors were transmitted wirelessly to a computer on the sideline and processed to measure both the linear and rotational head acceleration caused by each impact.
and equipment design especially in developing youth-specific helmets to better reduce accelerations from head impacts Rowson said.
In the Wake Forest Baptist study the researchers measured the head impact exposure in 40 high school football players by using sensors placed in their helmets to record linear and rotational acceleration.
The research team hopes that this work may ultimately improve helmet safety and design to make football a safer sport.

The region accounts for more than 25 percent of the world's tropical rain forests and is one of the four remaining extensive pristine forested areas left in the world (Amazon Congo Papua new guinea and Guiana Shield.
The Guiana Shield: Worthy of protectionnot least because of the high number of endemic species the region is one of the most important centres of biodiversity in the tropics of the New world.
Even though the forests of the Guiana Shield have had among the lowest deforestation rates of the world with very little change over the past decades rapid economic and social changes are posing increasing pressures on these relatively wellconservedforest ecosystems.
These researchers found that all 10 modern helmets provided significantly more protection than leather helmets used in the first half of the twentieth century
and demonstrated that differences also exist between modern helmets. Details on their methods and findings are found in Biomechanical performance of leather and modern football helmets.
Each helmet in turn was placed on the head form which was dropped in a controlled fashion from heights of 12 24 36 48 and 60 inches onto a standardized anvil to simulate impacts delivered from blows to the head during play.
and 2011 Virginia Tech Helmet Rating The measures were: 5 stars best available; 4 stars very good;
Each modern helmet was subjected to all 20 drop tests (four impact locations at five drop heights.
Each vintage leather helmet was subjected to 12 drop tests; the 48-and 60-inch drop tests were undertaken not
when covered by vintage helmets. Drop testing of modern helmets was conducted during an earlier study at
which time the modern helmets were assigned star ratings. Drop testing of vintage helmets was undertaken for the present investigation.
The ten modern helmets were split into two groups: six helmets with a four-or five-star rating in the first group and four helmets with a three-star or lower rating in the second group.
The two vintage helmets constituted a third helmet group. Based on the results of the drop tests the researchers calculated each helmet group's average peak accelerations for each head form position and each drop height.
Rowson and colleagues found that vintage leather helmets were associated with substantially greater peak accelerations for each drop height than all modern helmets.
In addition the researchers found modern helmets reduced the concussion risk by 45 percent for the 24-inch drop height and 96 percent for the 36-inch drop height.
Modern helmets with lower star ratings had greater peak accelerations for each drop height than modern helmets with higher star ratings
and the differences in peak accelerations between the two modern helmet groups increased with each increase in drop height.
All comparisons were statistically significant at a level of p<0. 001. The authors state that the purpose of the technical note is to provide insight as to how a previous study (Bartsch A et al.
Impact test comparisons of 20th and 21st century American football helmets. Laboratory investigation. J Neurosurg 116: 222-233 2012) could find little difference between older and modern helmets with respect to head impact doses
and head injury risks at the severity level of subconcussive injury. Rowson and his coauthors state that they offer biomechanical analysis based on helmet testing methodologies that compare relative helmet performance.
The source of their disagreement with the Bartsch study centers on the different methods used by the authors of the two studies.
Much of the discussion explains how differences in impact testing methodologies can influence the resulting data.
In an editorial companying the paper by Rowson and his colleagues (Editorial. Leather football helmets by Adam Bartsch Edward Benzel M d. Vincent Miele M d. and Vikas Prakash also published today online ahead of print in the Journal of Neurosurgery Bartsch

These researchers call for continued examination of experimental protocols that may lead to better quantification of helmet performance during simulated on-field conditions.

In one version of the model the researchers incorporated so-called black-body shields which absorb all of the radiation that strikes them.
In a second version opaque grey-body shields were used. A grey body has some transmission
Simonis and her colleagues found that as the reflectivity of the radiative shields increased the rate of heat transfer between the hot and cold thermostat was reduced dramatically.
Adding more shields also dramatically reduced the energy loss. All together the model suggests that the repeated backscattering of infrared light between radiative shields like individual hairs
and barbed feathers could be the primary mechanism for the thermal insulation properties of fur and feathers.
