3. Floods
A flood is an overflow of water that
submerges land which is usually dry. In
the sense of "flowing water", the word
may also be applied to the inflow of the
tide. Flooding may occur as an overflow of
water from water bodies, such as a river
or lake, in which the water overtops or
breaks levees, resulting in some of that
water escaping its usual boundaries, or it
may occur due to an accumulation of
rainwater on saturated ground in an areal
flood.

5. Tsunami
Tsunami waves do not resemble
normal sea waves, because their
wavelength is far longer. Rather than
appearing as a breaking wave, a
tsunami may instead initially resemble
a rapidly rising tide, and for this reason
they are often referred to as tidal
waves. Tsunamis generally consist of a
series of waves with periods ranging
from minutes to hours, arriving in a
so-called "wave train".

7. Limnic Eruption
A limnic eruption, also referred to as
a lake overturn, is a rare type of
natural disaster in which dissolved
carbon dioxide (CO2) suddenly
erupts from deep lake water,
suffocating wildlife, livestock and
humans.

9. Cyclone
A tropical cyclone is a storm system
characterized by a low-pressure
center and numerous thunderstorms
that produces strong winds and
flooding rain. A tropical cyclone
feeds on heat released when moist
air rises, resulting in condensation
of water vapour contained in the
moist air.
