On Friday (April 3), Palu, Central Sulawesi Province, was jolted by two consecutive earthquakes in the wee hours, causing a number of local residents to panic and wonder about the temblors` magnitudes. The first earthquake was 4.4 on the Richter scale and the second was 4.9 on the Richter scale. Indonesia, the world`s largest archipelago, sits on the Pacific "Ring of Fire," the edge of a tectonic plate prone to seismic upheaval.
