@DarcyProudman the berm closest to the power plant has been overtopped by a small(ish) amount of lava. The perched lava pool breached and sent lava towards the plant a day or so ago.
Workers are building a secondary berm between it and the power plant and also have been spraying water on the lava to slow/cool the lava down and hopefully stop it.
Activity in the main crater is slowing so hopefully they will control it for now but god knows how they will be able to protect the power plant going forwards
