Snow avalanches can be compared to landslides. Loose-powder avalanches move like a flow and slab avalanches move like a slide.
<h3>What is Avalanches?</h3>
Avalanches can start spontaneously, as a result of causes like increasing precipitation or decreasing snowpack, or by outside forces like people, animals, and earthquakes. Large avalanches can catch and move ice, rocks, and trees. They are mostly made of rushing snow and air.
The two main types of avalanches are slab avalanches, which are built of tightly packed snow and are caused by the collapse of a weak snow layer beneath them, and loose snow avalanches, which are made of looser snow. Avalanches typically accelerate quickly after being triggered and increase in bulk and volume as more snow is gathered. A powder snow avalanche could emerge if an avalanche moves quickly enough to mix part of the snow with the air.

The mountain ranges and rivers in Southeast Asia have made a stripe like relief in the mainland of this region. The mountain ranges are in a north-south direction and separate the region into few big elongated valleys, and the 5 big rivers also are moving from the north towards the south (southeast, southwest as well), and are running in between the mountain ranges and cut through the valleys.
This is why S-waves arrive as secondary waves at the Earth's surface. There is another importantdifference between P-waves and S-waves. Although both can pass through solid rock, only P-waves can also pass through gases and liquids.
One cycle of the moon phases last for almost around 29 and a half days or 29.5 days .
There are four phases of the moon .
The average number of days between 4 intermediate phases of moon is approximately 7.4 days , however between full , waning/waxing gibbous , waning / waxing crescent,and new moon is around 3.5 days .
