The 1.5-km-wide Boquerón crater of San Salvador is in the center of this November 2019 Planet Labs satellite image monthly mosaic (N is at the top), with the small Boqueroncito scoria cone in the center. A 6 x 4.5 km caldera formed around 40-30 ka and the current El Boquerón edifice was built within it. Recent activity was concentrated in the northern sector with lava flows emplaced on the N flank and within the crater.
