Luzon, Philippines Earthquake

Moderate earthquake at intermediate depth below San Juan, Luzon, Philippines

Last update: June 14, 2013 at 5:43 pm by By

Update 17:36 UTC : PHIVOLCS report a somewhat different picture mentioning a Magnitude of M4.9 at a depth of 26 km. A little more dangerous, especially for landslides.
Phivolcs does not expect damage and/or aftershocks. They are reporting an Intensity II at – Laoag City; Sarat, Ilocos Norte; Santa, Ilocos Sur and Baguio City.
Earthquake-report.com is a little more sceptical about this earthquake. Based on the Phivolcs data (preliminary of course) we would not be surprised that minor damage has occurred.
Phivolcs puts the epicenter right on the coastline vs more inland by USGS. It will take a little more time before seismologists have manually recalculated the data.

Update 17:35 UTC : The earthquake occurred at 1 AM when most people went to bed. Many of them will not have felt the shaking.

USGS reports a depth of 56 km (preliminary data) which makes this earthquake to be felt in a rather wide area (hundreds of km) but we are convinced that due to the depth this earthquake will not generate any damage.

PAGER is expecting intensities of VI.

A report from Madrid on the Surigao peninsula is of intensity VII (however this is only one value). Surigao has 2 reported intensities of V.

Considering the Masbate City earthquake of M5.2 and 23km depth the other week with a lower ground motion which caused 10 injuries and some housing damage, it is expected that this earthquake will also cause damage.
