[Vocabulary] “blasted across” meaning

[HardRus]

Hello everyone! I can't clearly understand a sentence. Could you help me?

It had taken two days of bushwhacking to reach the site. Six days later, Jensen would be the last man to leave. It was Jensen whom the Rio Tinto mining group, which had chartered the helicopter to carry employees from a Peruvian copper mine to the city of Chiclayo, had reached out to first. It was Jensen who had worked out a strategy for reaching the crash site after it became clear that the ten people aboard had been killed, the debris blasted across the wanton ridges of a tropical Yosemite.

What does "blasted across" mean here?

Thank you in advance.
