Episode 2 of 2
Philippine Fault System Rupture
- When
- June 30, 1879
- Where
- Surigao segment of the Philippine Fault System
The earthquake ruptured approximately 100 kilometers of the Philippine Fault System along the Surigao segment.
The rupture was associated with a fault scarp, an association reported in the source. Spanish geologist Jose Centeno measured up to 50 cm of ground subsidence following the event. The segment has experienced at least three other surface rupturing earthquakes in the last 1,300 years; this paleoseismic context is not dated to the 1879 event, and the rupture date is inferred from the earthquake's occurrence.
