Clock Struck 3.36 Am and Earthquake Struck Amatrice, Italy.
Posted on the 24 August 2016 by Sampathkumar Sampath
Amatrice
is a hilltop beauty spot famed as the home of amatriciana, one of Italy's
favourite pasta sauces. Amatrice, in fact, was due to have its annual festival
honouring its namesake food on August 27-28 in the historic center now rendered
to rubble. It is a popular destination for Romans seeking cool mountain air at
the height of the summer. Amatrice is a town and comune in the province of
Rieti, in northern Lazio (central Italy)– this city of agricultural base is in
news for wrong reasons!
Seismicity
in the Himalayan region dominantly
results from the continental collision of the India and Eurasia plates, which
are converging at a relative rate of 40-50 mm/yr. Northward underthrusting of
India beneath Eurasia generates numerous earthquakes and consequently makes
this area one of the most seismically hazardous regions on Earth. The
Indus-Tsangpo Suture Zone is located roughly 200 km north of the Himalaya Front
and is defined by an exposed ophiolite chain along its southern margin. To put
it simply it is tremors ~i.e., Earthquake !!!
The
April 2015 Nepal earthquake killed 9,000 people and injured more than 19,000
according to reports. It was the worst
natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake. The
earthquake triggered an avalanche on Mount Everest. Thousands were rendered homeless – some
monuments were flattened too. A second
major earthquake occurred on 12 May 2015 at 12:35 NST – this too caused deaths ! An earthquake (also known as a quake, tremor or temblor) is the perceptible shaking of the surface of the Earth,
resulting from the sudden release of energy in the Earth's crust that creates
seismic waves. Earthquakes can be violent enough to toss people around and
destroy whole cities.
The clock on the 13th
century tower in Amatrice, Italy, poignantly stopped just after Wednesday's
earthquake struck at 3.36am. The town
was one of the hardest hit in the disaster, with at least 17 dying there, from
a total of over 70 lives lost. Reports suggest
that the death toll from the earthquake
that hit Amatrice and other villages in central Italy is rising at an alarming
rate. Some reports however add that so
far it looks as if the number of fatalities will be substantially lower than
when an earthquake of comparable force hit the nearby city of L’Aquila in 2009,
killing 309 people. The casualty tally
will nevertheless be far higher than it should be in a country of Italy’s
wealth – but much lower than it might have been. The 6.2-magnitude earthquake,
like the one that devastated L’Aquila, struck at night.
Had people been at
work, in shops or at school, the outcome would have been much worse. Two years
ago, President of Italy’s National Council of Geologists, said that according
to some estimates, if the L’Aquila earthquake had struck when students were in
their classrooms, “the number of victims would have been thousands, not
hundreds”. It is still not simple ~ 'Half
the village has disappeared,' said Amatrice mayor Sergio Pirozzi, surveying a
town center that looked as if had been subjected to a bombing raid. 'To hear the mayor of Amatrice say his
village no longer exists and knowing that there are children among the victims,
is very upsetting for me,' he said. It was packed with visitors when the quake
struck.
The first quake
measured 6.2, according to the United States Geological Survey (USGS), which
said it occurred at a shallow depth of 10 kilometres (six miles). It measured
6.0 according to Italian monitors, who put the depth at only four km. A
5.4-magnitude aftershock followed an hour later. Strong tremors were felt in
the capital Rome, more than 100 miles from the epicenter near the city of
Perugia - the epicentre was between Norcia and Accumoli. The true horror of the Italian earthquake
disaster was revealed as witnesses
described the hellish scenes as 'like Dante's inferno' and shocking pictures
showed how four towns were almost wiped off the map.
There were cries of
people shouting for help - rescue workers arrived after one hour... one and a
half hours, states one media. Thereafter,
rescuers spoke of hearing children's screams from the rubble and locals were
spotted frantically digging with their bare hands to try and save loved ones. The
quake which devastated the mountainside towns and villages of Amatrice,
Accumoli, Arquata del Tronto and Pescara del Tronto was so powerful that it
even rocked buildings in the center of Rome more than 100 miles away and was
felt as far away as Croatia. The earthquake in Norcia
occurred in a shallow fault in the Apennines, a chain of mountains that form the
backbone of Italy’s ‘boot’. It is well known for being a highly complex and
geologically active region as it sits at a point where several tectonic plates
grind against each other.
According to the US
Geological Survey, the quake was caused
by the stretching of the Earth’s crust as the tectonic plates beneath moved
apart. Since the late Miocene a large basin has been opening up under the
western Mediterranean Sea at the point where the massive Eurasian tectonic
plate meets the African plate. The
earthquake in Norcia is thought to have been caused by the opening of the
Tyrrhenian basin occurring faster than the compression between the Eurasian and
African plates, causing the earth’s crust to stretch. At the location of the earthquake, the
Eurasian plate moves towards the northeast with respect to the African plate at
a rate of around 24mm/yr, according to the US Geological Survey.
Compared to other
much larger earthquakes, such as the one off the coast of Japan in 2011 which
was magnitude 9.0, it occurred at a much shallower depth which may account for the high levels of destruction
seen in Norcia. The most powerful earthquake in Italian history, magnitude 7.4
quake destroyed at last 70 towns and cities, causing death of around 60,000
people occurred at Sicily in Jan 1693.
The natural
disasters bring in untold hardships – quake destroys homes, buries people under
rubble, roads and structures are damaged, powerlines get disrupted thereby
bringing in darkness, food, medicine all
become scarce and sadly some humans resort to plundering when others are in distress
!
Sad to be reading this…
