Не паркуйтесь рядом с люками

Andrew Fine assumed lightning struck when he heard an explosion outside his Manhattan apartment on a recent Friday night. But after one of his kids told him to look out their window, seeing “a car completely engulfed in flames,” he heard two more loud booms — and soon discovered that manholes were erupting beneath two cars parked on the block.
On the street, he said, the explosions set off car alarms and blew up the brick sidewalk as flames torched the two cars.
“It’s definitely scary,” Fine said. “It’s totally random. But it’s amazing when that randomness hits so close to home.”
The scene was far from unusual.
Manhole fires and explosions have presented a public safety hazard in this city since the early 20th century. THE CITY documented the phenomenon in Feb. 2020 — and the numbers have only risen since then.
The latest Mayor’s Management Report tied a 31% increase in “non-structural fires” from 2020 to 2021 to a surge in emergency manhole incidents over the same period.
“The rise in non-structural fires is attributed to a rise in manhole fires which more than doubled from 2,587 in Fiscal 2020 to 6,104 in Fiscal 2021,” the report highlighted.
And the number of “blown cover” events — meaning a manhole top dislodged by the force of an explosion — reached 281 in the fiscal year 2021, which runs through June, according to data from the Fire Department, up from 134 in the previous year.

Взрываются канализационные люки. Я вот только не понимаю, чему там взрываться? Метан скапливается что ли? А отверстия сделать для выхода газа? Интересно, в Москве такие случаи сколь часты или там структура коммуникаций другая?
