Do I feel dizzy?

Yesterday, while I'm in the front of my computer, I feel the earth move under my feet, as I look around I see our chandelier is swaying, so here's a related news that I gather courtesy of Philippine Star.

"2 strong quakes jolt Luzon By Helen Flores"

"Two strong earthquakes rocked parts of Luzon yesterday but there were no immediate reports of damage or injuries, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Phivolcs director Renato Solidum said the tremors, of magnitude 6.5 and 5.3, occurred at 11:04 a.m. and 11:09 a.m., respectively.
Solidum said no tsunami warning was issued.
He said the earthquakes would not generate tsunamis because they were centered too deep underground. The first quake had a magnitude 5.3 and was centered 81 kms. underground and the stronger magnitude 6.5 was about 107 kms. deep.
The US Geological Survey reported the first was magnitude 5.6 and the second was a stronger but deeper magnitude 6.1.
Solidum said seismographs have already recorded some small aftershocks.
The first quake was located some 34 kms. northwest of Mamburao, Occidental Mindoro. It was felt at Intensity 5 in Calapan, Oriental Mindoro; Intensity 4 in Manila, Las PiƱas, Apalit, Pampanga; Intensity 3 in Batangas City, Tagaytay City, Quezon City and Makati City.
The second quake was centered 51 kms. northwest of Mamburao. It was felt at Intensity 5 in Calapan, Intensity 4 in Puerto Galera and Intensity 3 in Quezon City.
“The quakes are not expected to cause significant damage, however, aftershocks are expected,” Solidum said.
Magnitude refers to the measure of energy of an earthquake specified on the Richter scale.
On the other hand, the intensity of an earthquake is a measure of the severity of shaking and its attendant damage on the surface of the earth.
The Philippines sits on the so-called Pacific Ring of Fire, where continental plates meet, causing seismic and volcanic activity.
Solidum said about 20 earthquakes hit the country everyday but only a few are felt. – With AP"
