Strong quake shakes northern Philippines; no tsunami warning
Manila, Oct 25: A strong earthquake rocked the northern Philppines late on Tuesday, but officials said no serious damage was expected and no tsunami warning was issued.
The US Geological Survey said the magnitude 6.4 quake was centered 16.2 kilometers (10 miles) below the surface about 11 kilometers (7 miles) from Dolores on Luzon island.
The US Tsunami Warning System said no warning or advisory was issued.
The quake was felt across a wide area of northern Luzon, but the Philippine Institute of Volcanology and Seismology said it did not expect any major damage.
The Philippine archipelago lies on the "Pacific Ring of Fire," a region along most of the Pacific Ocean rim where many volcanic eruptions and earthquakes occur, making the Southeast Asian nation one of the world's most disaster-prone.
In July, a magnitude 7 earthquake set off landslides and damaged buildings in the northern Philippines, killing at least five people and injuring dozens.
A magnitude 7.7 quake killed nearly 2,000 people in the northern Philippines in 1990.

The maximum temperature is expected to hover around 21 degrees Celsius, with dense fog likely to persist through the day.
Meanwhile, the ban on the entry of non-Delhi private vehicles below BS-VI emission standards and enforcement of the 'No PUC, No Fuel' rule came into force in the national capital on Thursday as authorities stepped up measures to tackle worsening air pollution.
Fuel pumps are not dispensing fuel to vehicles without valid Pollution Under Control (PUC) certificates, with enforcement being carried out using automatic number plate reader cameras, voice alerts at fuel stations and police support.
