Hurricanes Vs. Volcanoes
A research into the devastation of
natural disasters in Spanish
speaking countries.
Natural Disasters
"Events such as hurricanes, earthquakes, floods, tsunamis, volcanic
eruptions, and tornadoes are natural disasters because they cause high
amounts of devastation. Spanish speaking countries are effected yearly
with such natural disasters.” Anna Neale and Connie Watson
What does the word
devastation mean to you?
A tragic event that affects a large number of
people.
 The event causes a large amount of emotional
stress.
 The event also causes a large amount of
physical and monetary damage.

What are the two natural disasters that effect
Spanish speaking counties?
Volcanoes
Hurricanes
Which is more devastating?
A hurricane or…..
Is a volcano more devastating?
 What
is your
hypothesis?
Dangers of Hurricanes
Hurricanes
Flooding
Tornadoes
In the last 30 years, inland flooding has
been responsible for more than half the
deaths associated with tropical
cyclones in the United States.
Hurricanes can produce tornadoes that
add to the storm's destructive power.
Tornadoes are most likely to occur in the
right-front quadrant of the hurricane.
High Winds
Storm Surge
Hurricane-force winds can destroy
poorly constructed buildings and mobile
homes. Debris such as signs and roofing
material become flying missiles.
The greatest potential
for loss of life related to a hurricane
is from a storm surge, which
historically has claimed 9 of 10 victims
Hurricanes


Dominican Republic 1508
“destroying...the entire
population of Buenaventura”
Mexico 1615 “San Miguel
(400 tons) sunk in storm.
"Nothing was saved, not
even the crew or
passengers.”

Cuba 1778 “greatest loss of
human lives by drowning”

Dominican Republic 1680
“submerged...many
vessels...(including) twentyfive ships of France...causing
the death of most several
Spanish ships lost as well.”
Volcanoes
Volcanoes
Volcanic Eruption
Lava Flow
Eruptions cause
the cone of the
mountain to grow
thousands of feet.
Lava flow will cover a large area
surrounding the volcano. The
lava can cover many miles of land
and destroy anything in its path.
Ash
Lightning
The ash from a volcanic
eruption will cover entire
cities, people, buildings, and
animals are all affected.
Volcanic activity also
can cause electrical storms
and danger from lightning.
Volcanoes
PARACUTIN
 Rarely do volcanologist get to
watch the birth, growth, and
death of a volcano. Paricutin
provided such an opportunity.
The eruption that created
Paricutin began in 1943 and
continued to 1952.
 Lava flows covered about 10
square miles and had a volume
of about 0.3 cubic miles.
 Three people were killed by
lightning associated with the
eruption.

The effect an eruption will have
on a nearby city could vary from
none at all to catastrophic. For
example, atmospheric
conditions might carry ash away
from the city or topography
might direct lahars and
pyroclastic flows to unpopulated
areas. In contrast, under certain
atmospheric, eruption and/or
topographic conditions, lahars,
pyroclastic flows, and/or ash fall
could enter the city causing
death and destruction.

devastation.
