It was serious enough that my GF and I went downstairs and stayed down there on the sidewalk for about 30 minutes before coming back up. Many others in the building did the same.
Glad you and yr girlfriend took these precautions and are safe.
Reuters says:
One official said any possible tsunami could be headed toward the Indian Ocean island of Mauritius.
There were no immediate reports of casualties, but Indonesia's Metro TV quoted a resident on the island of Nias, off western Sumatra, as saying buildings there were damaged.
"Things are quite bad right now," the resident said. "There is much damage. People are running in panic. Many people are also trapped."
He did not elaborate on what he meant by people were "trapped."
