Piñera was sworn in as the 34th President of the Republic of Chile on 11 March 2010, in a ceremony held in a plenary session of the National Congress in Valparaíso. In the same ceremony, Piñera's Cabinet ministers were sworn in. The ceremony was also marked by a 6.9 Mw earthquake and subsequent aftershocks that upset the invitees. Shortly after, the National Congress building was evacuated due to a tsunami alert that proved to be false a couple of hours later. On 12 October 2010, Piñera rallied his countrymen in the rescue of 33 trapped miners, all of whom were rescued after 70 days following a mining accident. "Chile will never be the same", he said to the miners' foreman, Luis Urzúa, as he (the last of the miners to emerge from the cavern) greeted Piñera, in a broadcast carried live across the globe. Despite much goodwill in Chile following this, many Chileans are still waiting on Piñera to rectify anti-terrorism laws in Chile which effectively mean the indigenous Mapuche people can be dealt with as "terrorists". This matter has led to hunger strikes which started before the mining disaster, and are set to continue afterwards.
