Rim to rim ~1.64 Km

I would have already liked to describe now the main eroded crater for the events that I have been postulated till here.

However, I think that, although I have many clues to confirm the accuracy of my deduction, I have still not yet sufficiently developed my observations and currently, I do not have tangible physical evidence directly taken in the principal main crater to satisfyingly and definitely attest my conclusion about.

During the next summer, some on-site inspections will be carried out in the main crater in order to gather the necessary physical evidence to complete a desirable good description and conclusion.

In addition to the foregoing, during a general review of the data by me gathered about other possible ideal meteorite impact geological structures found, some new information emerged that forced me to change a description in particular with regard to the Bellinzona crater.

So for these reasons I will explain why local geologists in my opinion are wrong in describing the physical evidence that I find as signs of pure glacial erosion and to other atmospheric and tectonic agents.

With regard to the obvious signs of metamorphosis of impact that I encountered inside and outside of Bellinzona's crater, the local geologists at the time six years ago I interviewed, described it as likely plutonic origin, or anyway of magmatic origin rocks then eroded by glaciers; in addition to what, the same geologic field experts said that, the deformations in the rocks by me described was caused by tectonic movements and not by the impact metamorphic effect like as I argue.

So below I go listing in detail why in my view my theory is more satisfactory:

- eroded shatter cones can be observed, both, on the outer and on the inner crater rim

- these shatter cones reflect obviously the characteristics found in other similar structures in the rest of the Earth's globe and largely described in literature, that is, their size with respect to impact energy power, their concentric direction towards to the impact epicenter, the presence in them of tangent fractures and not least the fact that, the shatter cones vertex outside the crater rim are pointing upwards and those inside crater rim are pointing downwards

- the hill Sasso Corbaro, which is nothing that the remains of the crater rim on the south side, according to my data , following the impact has suddenly been elevated

- the area designated as "Rock Gymnasium", instead, it is the northern edge of the crater; such fantastic example of the metamorphic power of the impact, has fortunately remained relatively intact until today, because placed in a mountain slope recess, and therefore, remained sheltered by excessive glacial erosion

Bellinzona impact description.

Distance from Impact: 820.00 meters ( = 2690.00 feet ) = (1/2 crater diameter)

Projectile diameter: 51.50 meters ( = 169.00 feet )Projectile Density: 8000 kg/m3

Impact Velocity: 21.00 km per second ( = 13.00 miles per second )Impact Angle: 45 degrees

Target Density: 2750 kg/m3Target Type: Crystalline Rock

Energy:Energy before atmospheric entry: = 3.01 x 10 MegaTons TNTThe average interval between impacts of this size somewhere on Earth during the last 4 billion years is 2.3 x 1000years

Major Global Changes:The Earth is not strongly disturbed by the impact and loses negligible mass.The impact does not make a noticeable change in the tilt of Earth's axis (< 5 hundreths of a degree).The impact does not shift the Earth's orbit noticeably.

Atmospheric Entry:The projectile begins to breakup at an altitude of 17'500 meters = 57'500 ftThe projectile reaches the ground in a broken condition.The mass of projectile strikes the surface at velocity 14.5 km/s = 9.03 miles/sThe impact energy is = 1.45 x 10MegaTons.The broken projectile fragments strike the ground in an ellipse of dimension 0.345 km by 0.244 km

Crater Dimensions:Crater shape is normal in spite of atmospheric crushing; fragments are not significantly dispersed.Transient Crater Diameter: 1.31 km ( = 0.815 miles )Transient Crater Depth: 464 meters ( = 1520 feet )Final Crater Diameter: 1.64 km ( = 1.02 miles )Final Crater Depth: 349 meters ( = 1150 feet )The crater formed is a simple craterThe floor of the crater is underlain by a lens of broken rock debris (breccia) with a maximum thickness of 162 meters ( = 531 feet ).The volume of the target melted or vaporized is 381000 m3 = 1.34e+07 feet3Roughly half the melt remains in the crater

Thermal Radiation:At this impact velocity ( < 15 km/s), little vaporization occurs; no fireball is created, therefore, there is no thermal radiation damage.

Seismic Effects:The major seismic shaking will arrive approximately 164 milliseconds after impact.Richter Scale Magnitude: 5.4

Ejecta:Most ejecta is blocked by Earth's atmosphere

To conclude my opinion is that, the rocks I described are eroded shatter cones left of the crater rim, so, not eroded magmatic plutonic rocks mainly deformated caused by tectonics movements.
