Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake-resistant construction. The predominant vulnerable building types are reinforced concrete and unknown/miscellaneous types of construction.
Recent earthquakes in this area have caused secondary hazards such as landslides that might have contributed to losses.
Liquefaction triggered by this earthquake is estimated to be significant in severity and (or) spatial extent. The number of people living near areas that could have produced liquefaction in this earthquake is extensive.
Little or no landsliding is expected, but some landslides could have occurred in highly susceptible areas. The number of people living near areas that could have produced landslides in this earthquake is low, but landslide damage or fatalities are still possible in highly susceptible areas.
According to Anthony Allada, public information officer of Magsaysay Town, Davao del Sur, 14 people were injured but none seriously.
Roads and buildings, including the local government office, were damaged and power was out in the town.
