Cyclone Ockhi Though the cyclone is moving 120km off Thiruvananthapuram and these areas are not directly on its path, the severity of the cyclone, which is presently traveling at 72.23 km/h (39kt), could have a life-threatening effect.

Tropical storms are known as the most catastrophic and destructive natural events.

The loss of life and property, flora and fauna, and the landscapes have focused the attention on scientists and revenue enumerators on the loss aspect alone.

However, studies by the United States Geological Survey (USGS) indicate that cyclonic storms have ecological benefits too.

Bruce Richmond of the USGS says, "tropical storms are as much as depositional event as an erosional event... little is known about their beneficial effects to coastal accretion."

The USGS website points to considerable evidence to demonstrate the powerful sediment-carrying capacity of storm overwash. (Overwash is the is the flow of water and sediment over a coastal dune or beach crest during storm events).

Atoll islands

Scientists say the formation of atoll islands is another feature of cyclones.

Such islands are formed by cyclonic action and house a variety of fauna.

Often, a chain of atoll islands are found formed due to cyclonic activity.
