Earthquakes happen every day, and as this animation shows, small ones happen more frequently than moderate-to-large earthquakes. However, April 2014 was unusual because there were more than the average number of moderate and large earthquakes. The Pacific Tsunami Warning Centre (PTWC) had to issue official warnings for 13 different earthquakes in that month. Of those 13, PTWC issued tsunami warnings for 5:
|1 April||8.2||Northern Chile|
|3 April||7.8||Northern Chile|
|12 April||7.6||Solomon Islands|
|13 April||7.7||Solomon Islands|
|19 April||7.8||Solomon Islands|
This animation shows all earthquakes on earth that occurred in the first quarter of this year. Note the typical level of activity through March. But starting with the 8.2 magnitude earthquake in northern Chile on April 1, the rest of the month saw 12 more moderate-to-large earthquakes mostly in Chile and the Solomon Islands but also in Nicaragua, Mexico, Canada, and even the south Atlantic Ocean. The animation concludes with a summary map showing all of the earthquakes in this four-month period.
