L'uragano Sandy devasta la costa est degli Stati Uniti


L'uragano Sandy si è spostato verso nord, verso il Canada, lasciandosi alle spalle una scia di morte e devastazione. Secondo gli ultimi bilanci, citati dall'edizione online del Washington Post, sono 50 le persone rimaste uccise durante la tempesta nei diversi stati dell'East Coast. E sono ancora 7,5 milioni le persone senza elettricità.

22 vittime solo a New York. Sale a 22 il numero delle vittime solo a New York. La situazione in città  continua ad essere difficile, con gran parte di Manhattan ancora al buio, soprattutto nella parte meridionale, la Lower Manhattan, che è stata la più colpita dalle inondazioni. E si teme che il blackout potrà andare avanti ancora per giorni. Anche la metropolitana rimarrà bloccata per diversi giorni, ha reso noto ieri il sindaco Michael Bloomberg, mentre oggi si prevede la parziale riapertura dell'aeroporto Kennedy International, con l'aeroporto La Guardia che rimarrà ancora chiuso.

Miliardi di danni. Enormi i problemi per il traffico aereo con 16mila voli cancellati finora. Mentre si fanno le prime stime dei danni immediati provocati da Sandy che, secondo Eqecat, società che calcola i danni provocati da catastrofi per le società di assicurazione, oscillano tra i 10 e i 20 miliardi di dollari (leggi).

New Jersey devastato. Oggi il presidente Usa Barack Obama si recherà in New Jersey: «Ci sono ancora rischi», avverte (video). Quella provocata dall'uragano in New Jersey è una «devastazione inimmaginabile», ha detto ieri il governatore dello Stato, Chris Christie, parlando di intere aree completamente sommerse dalle acque - tra cui la Jersey Shore, l'area costiera - e di danni a strade, ferrovie, ponti. «È qualcosa di mai visto. È terribile».

Il Papa. «Consapevole della devastazione causata dall'uragano che ha recentemente colpito la Costa Est degli Stati Uniti d'America, offro le mie preghiere per le vittime ed esprimo la mia solidarietà verso tutti coloro sono impegnati nell'opera di ricostruzione», ha detto oggi il Papa durante l'udienza generale in Piazza San Pietro. Benedetto XVI ha pronunciato le sue parole in inglese, rivolgendosi ai pellegrini di quella lingua, con riferimento agli effetti devastanti dell'uragano Sandy negli Usa. Già all'Angelus di domenica scorsa il Pontefice aveva manifestato la sua vicinanza alle popolazioni precedentemente colpite dall'uragano nei Paesi caraibici, invocando verso di loro «solidarietà» e «aiuti».

Ice Age Polarity Reversal Was Global Event


Some 41,000 years ago, a complete and rapid reversal of the geomagnetic field occured. Magnetic studies of the GFZ German Research Centre for Geosciences on sediment cores from the Black Sea show that during this period, during the last ice age, a compass at the Black Sea would have pointed to the south instead of north.

Moreover, data obtained by the research team formed around GFZ researchers Dr. Norbert Nowaczyk and Prof. Helge Arz, together with additional data from other studies in the North Atlantic, the South Pacific and Hawaii, prove that this polarity reversal was a global event. Their results are published in the latest issue of the scientific journal Earth and Planetary Science Letters.
What is remarkable is the speed of the reversal: "The field geometry of reversed polarity, with field lines pointing into the opposite direction when compared to today's configuration, lasted for only about 440 years, and it was associated with a field strength that was only one quarter of today's field," explains Norbert Nowaczyk. "The actual polarity changes lasted only 250 years. In terms of geological time scales, that is very fast." During this period, the field was even weaker, with only 5% of today's field strength. As a consequence, Earth nearly completely lost its protection shield against hard cosmic rays, leading to a significantly increased radiation exposure.
This is documented by peaks of radioactive beryllium (10Be) in ice cores from this time, recovered from the Greenland ice sheet. 10Be as well as radioactive carbon (14C) is caused by the collision of high-energy protons from space with atoms of the atmosphere.
The Laschamp event
The polarity reversal now found with the magnetisation of Black Sea sediments has already been known for 45 years. It was first discovered after the analysis of the magnetisation of several lava flows near the village Laschamp near Clermont-Ferrand in the Massif Central, which differed significantly from today's direction of the geomagnetic field. Since then, this geomagnetic feature is known as the 'Laschamp event'. However, the data of the Massif Central represent only some point readings of the geomagnetic field during the last ice age, whereas the new data from the Black Sea give a complete image of geomagnetic field variability at a high temporal resolution.
Abrupt climate changes and a super volcano
Besides giving evidence for a geomagnetic field reversal 41,000 years ago, the geoscientists from Potsdam discovered numerous abrupt climate changes during the last ice age in the analysed cores from the Black Sea, as it was already known from the Greenland ice cores. This ultimately allowed a high precision synchronisation of the two data records from the Black Sea and Greenland.
The largest volcanic eruption on the Northern hemisphere in the past 100,000 years, namely the eruption of the super volcano 39,400 years ago in the area of today's Phlegraean Fields near Naples, Italy, is also documented within the studied sediments from the Black Sea. The ashes of this eruption, during which about 350 cubic kilometers of rock and lava were ejected, were distributed over the entire eastern Mediterranean and up to central Russia.
These three extreme scenarios, a short and fast reversal of Earth's magnetic field, short-term climate variability of the last ice age and the volcanic eruption in Italy, have been investigated for the first time in a single geological archive and placed in precise chronological order.

Lo spostamento della crosta terrestre


Da uno studio congiunto condotto da scienziati norvegesi e tedeschi sembra che il pianeta stia subendo un vero e proprio slittamento di masse terrestri che starebbe provocando un "true polar wander"(reale migrazione dei poli).

La teoria infatti spiega che le masse solide del pianeta stanno subendo un epocale spostamento rispetto al centro vorticoso e liquido del pianeta (nucleo terrestre). Tale fenomeno starebbe influenzando l'asse terrestre che tenderebbe ad inclinarsi per controbilanciare questo disequilibrio. Tale fenomeno però non risulterebbe collegato alla dinamica della tettonica a zolle o alle fluttuazioni del campo magnetico terrestre.

Il fenomeno è stato osservato monitorando gli hot-spots, i punti caldi del pianeta da dove si generano nuovi vulcani e conseguentemente nuove masse terrestri. Secondo gli scienziati la crosta terrestre starebbe subendo uno spostamento rispetto alla parte fluida del pianeta con conseguente dislocamento dell'intera struttura a zolle del pianeta, aumentando la sismicità vulcanismo su scala globale.

Venus Transit Movie


New movies of the transit of Venus on 6 June 2012, viewed from two different locations on Earth, clearly show the parallax effects that have made Venus transits so important historically. The results were presented at the European Planetary Science Congress in Madrid, Spain.

The movies compress 6 hours of observations and 5000 individual images taken by optical and solar telescopes into a 40 second video. Data gaps due to cloudy conditions produce jumps in the otherwise smooth Venus motion across the Sun disk. The observations were taken from Svalbard in Norway and Canberra in Australia, which are separated by 11600km.
When the images from the two locations are superimposed, the parallax effect (which first allowed astronomers to measure the distance between Earth to the Sun) becomes clear. Parallax means that when the transit is viewed from widely separated points on Earth's surface, Venus appears to follow a different path in front of the Sun's disc. Precise observations of the duration of the transit -- together with an accurate measurement of the distance between the observation points -- means that the distance to Venus and to the Sun can be calculated via triangulation.
The images used in the movies were obtained by members of the European Space Astronomy Centre, which is located outside Madrid. Two of the observers, Miguel Pérez Ayúcar and Michel Breitfellner are on the science operations planning team for the Venus Express satellite, which has been orbiting Venus since 2006.
Pérez Ayúcar said, "During the hours of the transit we were delighted by the slow, delicate, gracious passage of Venus in front of the Sun. A perfect black circle, containing a world in it, moving in front of its looming parent star. How thankful we were to witness it. Now with these movies, we can share a sense of that experience."
Breitfellner said, "In the 18th century people realised that transits of Venus could be used to measure the distance from Earth to the Sun. Teams of astronomers were sent all across the world to measure this effect. The 2012 transit has its own historical importance -- it is the first that has occurred when a spacecraft is in orbit at Venus. Science teams are now working to compare observations of the Venus transit from Earth with simultaneous observations from Venus Express."
Colin Wilson, Operations Scientist for Venus Express, said, "Planetary transits are not just of historical interest, they have acquired a new importance in the study of newly discovered planets around other stars. Because we cannot image exoplanets directly, it is only by studying their transits that we can discover whether they harbour liquid water or other potential 'biomarker' molecules like methane or ozone. The Venus transit is an example much closer to home, offering us a chance to test our understanding of how to interpret transit data. This certainly added extra interest as we watched the Venus transit in June -- particularly knowing it was our last chance that we'd have to wait until 2117 to see the next one!"

Venus Transit Movie Shows Perspective in Viewing Our Solar System Sep. 28, 2012


La Terra si sta spaccando


Ben  39 terremoti hanno sconvolto il pianeta in questi ultimi tempi. Secondo Gheorghe Marmureanu – del National Institute of Earth Physics della Romania – esperto di terremoti, nelle prossime 48 ore il pianeta potrebbe essere scosso da una nuova serie di violenti terremoti.

Una serie cominciata con i due violenti terremoti che hanno colpito l'Indonesia di magnitudine 8.6 e 8.2 della scala Richter seguiti da altre tre scosse lievemente più leggere che hanno colpito il Messico, poi il Costarica, fino alla più recente scossa di magnitudo 7.4 che ha interessato la Colombia.

“Sono certo che c'è qualche anomalia. Si stanno verificando troppi terrermoti senza alcuna possibilità di prevederli”, ha detto Marmureanu.
