NO.
Yes, they are likely to occur.
Fiji dont usually get Earthquakes or tsunamis. Fiji only faces tropical hurricanes every year and so. The recent Earthquake in Chile (March 04/2010) saw huge waves in Fiji and all over the south pacific because of its great impact.
Fiji experiences earthquakes throughout the year due to its location along the Pacific Ring of Fire, where tectonic plates interact. While seismic activity can vary, there is no specific season for earthquakes in Fiji; they can occur at any time. Most earthquakes are minor, but the region can experience significant tremors as well. Monitoring agencies keep track of seismic activity to provide timely information to residents.
