Ignition of forest tracts as a result of cosmic or technogenic catastrophes

Using a quasi-one-dimensional approximation, the problem of extensive forest fires caused by collisional or technogenic catastrophes is formulated and solved. Calculations show that the mechanism of ignition in both cases is the same, but the quantitative parameters of the processes (ignition time and limiting conditions, shape of ignition zone) differ significantly from each other. The cause is the difference in the mechanisms of energy release in the near-ground atmospheric layer during technogenic or collisional catastrophes.
