Home video shot during Hurricane Sandy shows one neighborhood tree after another falling.

With the storm gone, cleanup is now in full swing in yards and neighborhoods across Maryland after Sandy sent tree after tree crashing down, damaging homes, property and power lines.

Some, like Deborah Schwengel, narrowly avoided disaster when the tree holding her kids’ tree house came crashing into her son’s bedroom.

“Had he been sleeping up there, he could have been impaled by it but fortunately, no one was in the room,” she said.

But from Sandy to Irene to this summer’s powerful derecho, toppling trees to kill. Monday night, Don Cannata died when a tree ripped through his Pasadena home. Wednesday afternoon, a falling tree claimed the life of a tree trimmer working at a home in Annapolis.

“It’s a worry that never goes away and that’s what I find is just a lot of customers are continuously worrying,” said Stephan Szoke, Ameritree.

Tree experts say it’s important to have trees close to homes and roads routinely assessed.

“If folks keep the trees pruned properly, there’s less of a chance of things happening,” said Chris Meinecke, Keil Tree Experts.

“Trees are dangerous and I usually have them inspected regularly and cut them down when they are sick but this tree was a healthy tree. The wind just toppled it,” said Schwengel.

“When you have 80 mile an hour winds, it’s just how that air hits that tree. It can push it one way, then the other way and then there she goes,” Szoke said.

Because as the home video during Sandy shows, there’s nothing that can stop the power of Mother Nature’s strongest storms.
