The term symbol is used to allude to a reverential image. Normally, it is painted on a leveled wooden board, although in Ethiopia, since in different conventions, materials, for example, metal or stone could also be used to create this type of image. The closest known Ethiopian symbols have been dated to the 15th century and, for the most part, painted with rubber-based paint on ESSO prepared wooden boards. Ethiopian symbols of this period generally represent the Virgin and the Child, the Apostles and San Jorge.

The piece appeared here, which can be dated probable with the second 50% of the fifteenth century, includes correctly a mixture of subjects. On the left plate, the child communicates with the Mother's jaw line, an offer of delicacy that shows more times in works of this period on. The focal torque is flanked by two sacred messengers with unsheathed swords that go as their illustrious vigilante.

The correct plate is designed with images of the apostles that convert their appearance into worship towards the Virgin and the Child. In the right right corner there is a representation of Saint George riding a horse. The names of some of the figures on the correct board have been composed of the lines what divides the scene into records. All things considered, the engravings that recognize the upper column of the apostles and the Virgin and the child were initially present at the top edge of the two joints.

A site that has especially demonstrated support in separate puncture, the effect of the calculation and the different components is the Bowl of the Eel River of Northern California. There, scientists have planned approximately 200 slow avalanches and currently checking 10 or more using the Instr. These slides live in environments and practically indistinguishable environments. Only its sizes and shapes contrast.

At Eel River, researchers have discovered that few outside of each strange avalanche have a trigger reaction for hair to precipitation: it can rain for a long time or months before it has development. The group has discovered that the fine creation of these avalanches, unlike mathematics or the environment, has the most to decide its behavior. "In short, fine grain floors with mud rich material have a slower reaction, and soils or beads with grain by courses with huge breaks or cracks have a faster reaction," says Alexander HandWorker, a geoscientist in the laboratory Propulsion to NASA reaction in Pasadena, California.

However, when organizing this data to make expectations will be a test. For quite some time, geologists have been collecting information to easily measure the connections between the movement of the avalanche and the length and precipitation force. In any case, topographic materials and hydrological conditions are enormously factories, says Schulz, and the degree of accuracy that the conjecture slides is expected to remain the scope of researchers. In addition, in numerous nations, the movement of the avalanche is also vigorously influenced by another wonder whose impact has not been so completely examined: tremors.
