| Zusammenfassung |
| A devastating earthquake struck Bohol, Philippines, on 15 October 2013. The
earthquake originated at 12 km depth from an unmapped reverse fault, which
manifested on the surface for several kilometers and with maximum vertical
displacement of 3 m. The earthquake resulted in 222 fatalities with damage
to infrastructure estimated at USD 52.06 million. Widespread landslides and
sinkholes formed in the predominantly limestone region during the earthquake.
These remain a significant threat to communities as destabilized hillside
slopes, landslide-dammed rivers and incipient sinkholes are still vulnerable
to collapse, triggered possibly by aftershocks and heavy rains in the
upcoming months of November and December. The most recent fatal temblor
originated from a previously unmapped fault, herein referred to as the
Inabanga Fault. Like the hidden or previously unmapped faults responsible for
the 2012 Negros and 2013 Bohol earthquakes, there may be more unidentified
faults that need to be mapped through field and geophysical methods. This is
necessary to mitigate the possible damaging effects of future earthquakes in
the Philippines. |
