Did you feel the tremors this morning?
Two earthquakes hit northern Sumatra this morning sending tremors that were felt in Selangor, Malacca, Negri Sembilan, Perak, Putrajaya and here.
According to Jakarta Post, a magnitude-5.5 earthquake rattled Tarutung in the North Sumatra regency of North Tapanuli on Tuesday morning, with no casualties reported so far. The epicenter of the quake was 30 kilometers southeast of Tarutung, at the depth of 10 kilometers below sea level.

In other parts of Indonesia, The Jakarta Globe reported that a 5.1-magnitude earthquake struck off Palu, Central Sulawesi, on Monday, according to the Meteorology, Climatology and Geophysics (BMKG).
The moderate quake struck at a depth of 10 kilometers at 15.40 p.m. 120 kilometers off Palu.
It was the second quake in Indonesia today after a 4.7-magnitude quake hit Blitar, East Java at 10.17 a.m.
A third earthquake, a 6.9-magnitude earthquake, hit off Tahuna, North Sulawesi, at 9:31 p.m.
It was Indonesia's third earthquake on Monday — the first was in Blitar, East Java, and the second in Palu, Central Sulawesi.
There were no reports of injuries or damages. No tsunami warning had been issued.
Indonesia sits on the Pacific “Ring of Fire,” where the meeting of continental plates causes high seismic activity, and Sumatra is particularly prone to earthquakes.
