1861, February 16 about 19:00 [Local Time]. There was an earthquake of exceptional strength and great duration, accompanied by a tsunami, on the entire western coast of Sumatra. It was catastrophic on the Batu Islands. A large number of homes in the districts of Mandeling (vicinity of Pendjabunga) and Angkola; fields were made havoc of; colossal avalanches buried villages; Sialang was so buried that not a trace remained of it. At Singkel, most of the homes, in particular the barracks, were left unsuitable for further use; the ground cracked. On Nias Island, the earthquake was even stronger than everywhere else. At Fort Laundi, the soldiers were bowled over. The same occurred at Gunungsitoli. On the north, the earthquake spread to Atjeh, where it caused considerable destruction and human victims. No less damage was done by the earthquake at Batak. It was felt at Dacca and caused seiches in ponds on the east of India. An unusual trembling of level, ascribed to this earthquake was noted at the Pulkovo astronomical observatory during observations of February 16, 1861.

The earthquake was accompanied by an enormous number of aftershocks.
