Seventeen NISAR radar frames trace Krasheninnikov's lava as it overflows its crater

NISAR scientists turned 17 radar frames of Kamchatka's Krasheninnikov volcano into a time-lapse of lava filling and overflowing its crater. Two looks every 12 days are enough to follow a lava field that grows over months, though the satellite began imaging about five months into the eruption.
