Mud volcano is formed from mud ejected with gases and water from hot
spring, geyser, etc. There are 7000 known mud volcanoes
worldwide, and about 4000 of these are found in eastern Azerbaijan and the
Caspian Sea. The rest are in Trinidad, Alaska and the Andaman Islands. The newest is in Sidoarjo, East Java. It
is unusual because it is huge and according to Sam Rice, a Geologist from
Cambridge University, it is probably between typical mud volcano and
hydrothermal vent, with an unlikely high temperature of 60 degrees
Celcius, containing a high concentration
of hydrogen sulfide gas that suggests there exist some kind of a volcano or
hypothermal activity. Mud and gas accumulation is formed when
sea sediment and sea water are trapped, when one tectonic plates slides under
another continental plate. The gas erupts from a volcano or a crack in the
earth’s crust because of oil drilling or an earthquake. |

A landslide or a landslip is a geological phenomenon which includes a wide range
of ground movement, such as a rock falls, deep failure of slopes and shallow
debris flows, which can occur in off shore, coastal and on shore
environments. Although the action of gravity in the primary driving force for
a landslide to occur, there are other contributing factors affecting the
original slope stability. Typically, pre conditional factors build up
specific sub surface conditions that make the area/slope prone to failure,
whereas the actual landslide often requires a trigger before being released. Landslide occur when the stability of a slope
changes from a stable to an unstable condition. A change in the stability of
a slope can be caused by a number of factors, acting together or alone.
Natural causes of landslides include; groundwater (pore water) pressure acting
to destabilize the slope, loss or absence of vertical vegetative structure,
soil nutrients and soil structure, erosion of the toe of a slope by rivers or
ocean waves, weakening of a slope through saturation by snowmelt, glaciers
melting, or heavy rain, earthquakes and volcanic eruptions. Landslides are aggravated by human activities such
as: deforestation, cultivation and construction which destabilize the already
fragile slopes, vibrations from machinery or traffic, blasting, earthwork
which alters the shapes of a slope, or which imposes new loads on an existing
slope. There are some type of landslide; debris flow, earth flow, debris
avalanche and shallow landslide in which the sliding surface is located
within the soil mantle or weathered bedrock ( typically) to depth from few
decimetres to some metres. |
A. Rock falls, deep failure
of slopes and shallow debris flows.
B. groundwater, soil
nutrient and soil structure
C. Deforestation,
cultivation, and construction.
D. Snowmelt,
glaciers melting or heavy rain.
5. What is the main idea of the
third paragraph?
A. A. some
type of landslides
B. B. Natural
caused landslide
C. C. landslide
caused by human activity
D. D. Vibration
of machinery caused landslide
