What Caused Thursday's
Devastating Earthquake?
A land fault located
along the Sarapiquí
river that runs between
the Poás and Barva
volcanoes is the cause
of Thursday's 6.2 quake
in Cinchona de Sarapiquí,
according to an
explanation by Eliécer
Duarte, an earthquake
specialist for the
Observatorio
Vulcanológico y
Sismológico de Costa
Rica (Ovsicori).
In a major earthquake
the ground may rupture,
with ruptures typically
occurring along existing
fault lines. Duarte
explains that the
Sarapiquí fault is
thousands of years old.
Duarte and a tema of 11
people visited the area
of disaster on Friday
for a close inspection,
noting the movement of
the two sides of the
fault, one side
commencing between
Sabana Redonda and
Fraijanes, meeting at
the epicentre of
Thursday's quake,
located between Vara
Blanca and Cinchona.
The second part is
located near the
Catarata La Paz heading
northeast to San Miguel
de Sarapiquí.
The expert explained
that the devastation was
total in the area of the
epicentre.
"The homes at the centre
of epicentre were
completely destroyed,
the majority flattened
by the seismic impact",
said Duarte.
The inspection also
revealed that thousands
of hectares of virgin
forest were now at the
bottom of rivers and
their tributaries. |
