PHIVOLCS - Baguio Station is a government agency that is responsible of monitoring the activity of the tectonics plates below and detect the earthquakes and volcanic activities. The person in-charge told us that it is impossible to predict an earthquake or volcanic eruption.

Since the our country is included in the Ring of Fire, they perform their task using various equipments. They have a broadband seismograph which uses the telephone line or radio frequencies and display results in a computer. This device has a wide range.They also have a short period seismograph which interprets results graphically. This however has a narrow range but is useful if there id no electricity. Both devices are used to measure the vibration or any movement in the earth’s crust.
