1. GROUP I
BOXING DAY TSUNAMI: THE FACTS ABOUT THE 2004 INDIAN OCEAN
DISASTER
It has been 10 years since the Indian Ocean tsunami and earthquake
devastated parts of Indonesia, Sri Lanka, India and Thailand.
The disaster was the world's deadliest tsunami, with over 230,000 people
killed and half a million injured by the waves that battered the low-lying coast.
The exact death toll is unknown. It was 7:58 a.m., December 26, 2004 when the
tremendous quake struck beneath the Indian Ocean 160 miles west of Sumatra.
Not only did it register at approximately a 9.3 magnitude (only the 1960 Chile
earthquake measured higher at 9.5, though there may have been stronger
tremors prior to the invention of seismographic equipment) and last nearly 10
minutes, the quake moved a full 750 miles of underwater fault line earth up to 40
feet. The movement of the earth–there is evidence that huge boulders weighing
thousands of tons were pushed several miles along the ocean floor–caused a
massive displacement of water. It is estimated that the resulting tsunami had an
energy of 23,000 Hiroshima-type atomic bombs used during World War II.
The violent movement of the Earth’s tectonic plates displaced an
enormous amount of water, sending powerful shock waves in every direction. It
was the result of the Indio-Australian Plate subducting below the Eurasian Plate.
The tectonic plates in this area had been pushing against each other and building
pressure for thousands of years. They continue to do so and will likely cause
underwater earthquakes and tsunamis in the future. The rupture was more than
600 miles long, displacing the seafloor by 10 yards horizontally and several yards
vertically. As a result, trillions of tons of rock moved, causing the largest
magnitude earthquake in 40 years.

THE GREAT 1906 SAN
FRANCISCO EARTHQUAKE
The worst natural disaster
in U.S. history
By: Chris Frantz
At 5:12 a.m. on April 18, 1906, the people of San Francisco were
awakened by an earthquake that would devastate the city. The main temblor,
having a 7.7–7.9 magnitude, lasted about one minute and was
the result of the rupturing of the northernmost 296 miles of the 800-mile San
Andreas fault. But when calculating destruction, the earthquake took second
place to the great fire that followed. The fire, lasting four days, most likely started
with broken gas lines (and, in some cases, was helped along by people hoping to
collect insurance for their property—they were covered for fire, but not
earthquake, damage). With water mains broken, fighting the fires was almost
impossible, and about 500 city blocks were destroyed. The damages were
estimated at about $400,000,000 in 1906 dollars, which would translate to about
$8.2 billion today.
In 1906 San Francisco was the ninth largest U.S. city with a population of
400,000, and over 225,000 were left homeless by the disaster. The death toll is
uncertain. City officials estimated the casualties at 700 but more modern
calculations say about 3,000 lost their lives. The lowballing city figures may have
been a public relations ploy to downplay the disaster with an eye on rebuilding
the city. On April 20, the U.S.S. Chicago rescued 20,000 victims, one of the
largest sea evacuations in history, rivalling Dunkirk in World War II. Martial law
was not declared, but some 500 looters were shot by police and the military.
The epicenter of this earthquake has moved around in the past 100 years,
as advances in seismology have been made. It was first thought to have been in
Marin County, then northwest of the Golden Gate, and most recently, in the
Pacific Ocean about two miles west of San Francisco. The plate-tectonics theory
that would shed some light on the quake wasn't formulated until the 1920s and
not embraced until some three decades later. The San Andreas fault is on the
boundary between the Pacific plate and the North American plate. During the
earthquake, the ground west of the fault tended to move northward and, in the
most extreme instance, a 21-foot shift was measured. Earthquake ruptures are
fast movers—seismologists estimated the average speed of this rupture to have
been 8,300 mi/hr going north, and 6,300 mi/hr traveling south. The quake was
felt from southern Oregon to south of Los Angeles and inland as far as central
Nevada.

How the Marianas Trench Became
Earth's Deepest Point By Richard
A. Lovett, for National Geographic
News
James Cameron made headlines last month by successfully diving 6.8
miles (11 kilometers) to the deepest part of the Mariana Trench in a one-person
submersible called the DEEPSEA CHALLENGER.
Best known as a Hollywood director and now a National Geographic
Society explorer-in-residence, Cameron is one of just three people to dive to
Earth's deepest point, and the only one to be able to stay long enough to look
around.
The Mariana Trench isn't really the deep, narrow furrow that the word
"trench" implies. Rather, the abyss marks the location of a subduction zone. It
occurs where one part of the seabed—in this case the Pacific plate—dives
beneath another, the Philippine plate. Though tectonic forces eventually warp the
Pacific plate so that it makes a near-vertical dive into the Earth's interior, at
seabed level the plate dips at a relatively gentle angle.
A tectonic plate is a huge hunk of rock, 60 miles (97 kilometers) or thicker,
said Robert Stern, a geophysicist at the University of Texas, Dallas. "In order for
this to sink back into the earth, it has to bend downward, and these are very
gentle bends."
One reason the Mariana Trench is so deep, he added, is because the
western Pacific is home to some of the oldest seafloor in the world—about 180
million years old.
Seafloor is formed as lava at mid-ocean ridges. When it's fresh, lava is
comparatively warm and buoyant, riding high on the underlying mantle. But as
lava ages and spreads away from its source, it slowly cools and becomes
increasingly dense, causing it to settle ever lower—as is the case with the
Mariana Trench.

THE 2011 JAPAN TSUNAMI WAS CAUSED BY
LARGEST FAULT SLIP EVER RECORDED Shifting
plates and rising water
The sudden movement of the Pacific tectonic plate under the North
American plate caused a massive earthquake and a tsunami. The effects of the
great earthquake were felt around the world, from Norway's fjords to Antarctica's
ice sheet. Tsunami debris continues to wash up on North American beaches two
years later.
The Tohoku earthquake fault is a complex mosaic, with patches that stick
and patches that slide smoothly. Though the entire fault ruptured, or broke apart,
during the earthquake, some parts moved in different ways. The deeper part of
the fault shifted quickly, while the shallow part, very near the surface, slid slowly.
The Japan Trench is the result of the Pacific Ocean plate pressing down
under the continental plate carrying the islands of Japan. The downward
movement is called subduction.
The effects of the great earthquake were felt around the world, from
Norway's fjords to Antarctica's ice sheet. Tsunami debris continues to wash up
on North American beaches two years later. In Japan, residents are still
recovering from the disaster. Radioactive water was recently discovered leaking
from the Fukushima Daiichi Nuclear Power Plant, which suffered a level 7
nuclear meltdown after the tsunami. Japan relies on nuclear power, and many of
the country's nuclear reactors remain closed because of stricter seismic safety
standards since the earthquake. Four years after the quake, about 230,000
people who lost their homes were still living in temporary housing, Japan's
Reconstruction Agency said.
In Japan, residents are still recovering from the disaster. Radioactive
water was recently discovered leaking from the Fukushima Daiichi Nuclear

years after the quake, about 230,000 people who lost their homes were still living
in temporary housing, Japan's Reconstruction Agency said. The total damages
from the earthquake and tsunami are estimated at $300 billion dollars (about 25
trillion yen), according to the Japanese government.
The unexpected disaster was neither the largest nor the deadliest
earthquake and tsunami to strike this century. That record goes to the 2004
Banda Aceh earthquake and tsunami in Sumatra, a magnitude-9.1, which killed
more than 230,000 people. But Japan's one-two punch proved especially
devastating for the earthquake-savvy country, because few scientists had
predicted the country would experience such a large earthquake and tsunami.
The tsunami caused a cooling system failure at the Fukushima Daiichi
Nuclear Power Plant, which resulted in a level-7 nuclear meltdown and release of
radioactive materials. The electrical power and backup generators were
overwhelmed by the tsunami, and the plant lost its cooling capabilities. In July
2013, TEPCO, the Tokyo Electric Power Company, admitted that about 300 tons
of radioactive water continues to leak from the plant every day into the Pacific
Ocean.

WHAT IS HAPPENING AT SURIGAO DEL NORTE?
At 10:03 PM on 10 February 2017, Friday, a strong earthquake of
magnitude 6.7 shook the island of Mindanao. The epicenter is located 16 km
offshore northwest of Surigao City, Surigao Strait at a depth of 10 km. The
earthquake was generated by the movement of Surigao segment of the
Philippine Fault. Small-magnitude earthquakes followed afterwards, and as of
4:00 PM of 11 February 2017, 101 aftershocks have been recorded by the
PHIVOLCS seismic monitoring network.
Why do earthquakes occur in Surigao del Norte?
Eastern Mindanao, including Surigao del Norte, is one of the seismically
active areas in the country because of the Philippine Fault and Philippine Trench,
which are the main earthquake generators that can affect the area. In addition,
there are other local faults which can be sources of small- to large-magnitude
earthquakes.
The Philippine Trench is the zone where the Philippine Sea Plate (PSP)
subducts beneath the Philippine Mobile Belt (PMB) between offshore Bicol
Peninsula and southeast Mindanao. Convergence between the PSP and the
PMB occurs at the rate of 8 cms/year.
Aside from strong ground shaking, what other seismic hazards are lifethreatening?
Landslides, rock falls, and other types of mass movements may occur in
mountainous or hilly areas. Liquefaction, manifested by sand boils or lateral
spread may affect low-lying, water-logged, sandy areas at the banks of rivers.
Tsunami is not expected from the kind of movement of the Philippine Fault -
Surigao segment. The tsunami threat for Surigao del Norte would come from the
movement of the Philippine Trench, located east of the province.
What should be done by the affected communities?
People are reminded to be cautious of structures visibly weakened or with
signs of damage by the 10 February 2017, as these may be further damaged by
aftershocks. In case of houses and other buildings with visible damage, it is best
to contact the Municipal/City Engineering Office for advice. Engineers from the
local government, other agencies and organizations should inspect buildings and
other infrastructures to determine their integrity, and recommend appropriate
actions to concerned affected groups or individuals. Slopes should be checked
for tension cracks that may have resulted from the strong ground shaking.
Tension cracks may make slopes more susceptible to landslides. These areas
should be avoided.
The best course of action is preparedness. In case of another felt
earthquake, it is recommended that people protect themselves by doing the
“duck, cover and hold”. In homes and offices, heavy furniture should be strapped
to the walls, and appliances be secured to prevent them from toppling and
causing injuries to persons.
What is the role of PHIVOLCS?
PHIVOLCS operates and maintains a network of 92 seismic stations
spread across the Philippines. Data from the seismic stations are used to
determine the location, magnitude and other characteristics of the earthquakes
generated.
