It probably is mostly traffic as it's concentrated more at Cork and the east coast. The west coast would be much more hazardous than the east coast as it's exposed to the Atlantic ocean usually bares the brunt of most storms we get.You can see this on the map itself in how the west coast has eroded. Most of what is happening on the west coast would be fishing. Quite a few of the wrecks also seem be close to the coast because sinking ships had time to reach the coast before they completely sank.
