In 2004, a volcano erupted at the island of Hawaii and most of the people which where there died.
The volcano erption feel quickly down the mountain and all the tourists who where there died instantly but only 2 people survived. One woman and one man. they where survivers, all hey coud see was a lot of mud in the air and also a plane which was flying before the volcano  eruption.
nowadays ther are stilll in shock and they need help to go over that traumatic experience. When they close their eyes, they can only see all tat people down, on the floor and all they can hear is a silence and more sience.
Since that day there is more security to protect more the people who go there to make their lives safer.
