48. I'll help:

This list is just since 2010:

January 27, 2010: North Korea fires artillery shells into the water near Baengnyeong Island and South Korean vessels return fire.[29][30] Three days later, North Korea continued to fire artillery towards the area.[31]
March 26, 2010: A South Korean naval vessel, the ROKS Cheonan, was allegedly sunk by a North Korean torpedo near Baengnyeong Island in the Yellow Sea. A rescue operation recovered 58 survivors but 46 sailors were killed. On May 20, 2010, a South Korean led international investigation group concluded that the sinking of the warship was in fact the result of a North Korean torpedo attack.[32][33] North Korea denied involvement.[34] The United Nations Security Council made a Presidential Statement condemning the attack but without identifying the attacker.[35]
October 29, 2010: Two shots are fired from North Korea toward a South Korean post near Hwacheon and South Korean troops fire three shots in return.[36]
November 23, 2010: North Korea fired artillery at South Korea's Greater Yeonpyeong island in the Yellow Sea and South Korea returned fire. Two South Korean marines and two South Korean civilians were killed, six were seriously wounded, and ten were treated for minor injuries. About seventy South Korean houses were destroyed.[37][38][39] North Korean casualties were unknown, but Lee Hong-gi, the Director of Operations of the South Korean Joint Chiefs of Staff (JCS), claimed that as a result of the South Korean retaliation "there may be a considerable number of North Korean casualties".[40]
October 6, 2012: An 18-year-old North Korean Army private defects to South Korea. He is apparently not detected as he crossed the DMZ and has to knock on an ROK barracks door to draw attention to himself. The soldier later tells investigators that he defected after killing two of his superiors.[41][42]
September 16, 2013: A 47-year-old man is shot dead by South Korean soldiers while trying to swim across the Tanpocheon Stream near Paju to North Korea.[43]
February 26, 2014: South Korean defense officials claim that despite warnings a North Korean warship has repeatedly crossed into South Korean waters overnight.[44]
March 24, 2014: A North Korean drone is found crashed near Paju. The onboard cameras contain pictures of the Blue House and military installations near the DMZ. Another North Korean drone crashes on Baengnyeongdo on March 31.[45][46]
October 10, 2014: North Korean forces fire anti-aircraft rounds at propaganda balloons launched from Paju. South Korean military return fire after a warning.[47]
October 19, 2014: A group of North Korean soldiers approach the South Korean border and South Korean soldiers fire warning shots. The North Korean soldiers return fire before retreating. No injuries or property damage result.[48]
June 15, 2015: A teenaged North Korean soldier walks across the DMZ and defects at a South Korean guard post in north-eastern Hwacheon.[49]
August 4, 2015: Two South Korean soldiers were wounded after stepping on landmines that had allegedly been laid on the southern side of the DMZ by North Korean forces next to a ROK guard post.[50] Kim Jin Moon of the South Korean-based Korea Institute for Defense Analyses, suggested that the incident was planned by members of the General Bureau of Reconnaissance to prove their loyalty to Kim Jong-un.[51]
August 20, 2015: As a reaction to the August 4 landmines, South Korea resumed playing propaganda on loudspeakers near the border.[52] In 2004 both sides had agreed to end their loudspeaker broadcasts at each other.[53] North Korea threatened to attack those loudspeakers, and on August 20 North Korea fired a rocket and shells across the border into Yeoncheon County. South Korea responded by firing artillery shells back at the origin of the rocket. There were no reports of injuries on either side.[52][54] Following threats of war from the North, and various troops movements by both North and South Korea and the United States, an agreement was reached on August 24 that North Korea would express sympathy for the landmine incident in return for South Korea deactivating the loudspeakers.[55]
January 3, 2016: South Korean soldiers fired warning shots at a suspected North Korean drone near the DMZ
