This caldera from a super volcano was formed only 3500 years ago. Aniakchak Caldera formed during an enormous explosive eruption that expelled more than 50 km3 (11.5 cubic miles) of magma. The caldera is 10 km (6.5 miles) in diameter and 500-1,000 m (1/2 mile) deep. Subsequent eruptions formed domes, cinder cones, and explosion pits on the caldera floor.
Ilopango is a caldera that formed in 260 A.D. Ash from this explosive eruption covered much of central El Salvador. Lake Ilopango fills part of the caldera. Islas Quemadas, a volcanic dome, formed within the caldera in 1879-1880. Periods of dome extrusion coincided with tidal forces. Earthquake swarms preceded each extrusion.

I found an upload showing the enormous arrow drawn on the ground on Lanzarote island in the Atlantic. I zoomed out and eyeballed where the arrow points. Over egypt among other places. So I drew a line from the arrow to the pyramids for fun. Check out how it lines up with the arrow.
Lanzarote is a beautiful island that is of volcanic origin. The Spanish island, is the easternmost of the Canary Islands, in the Atlantic Ocean ca. 125 km off the coast of Africa as well as 1,000 km from the Iberian Peninsula. In 1730, the island was hit by a volcanic eruption. The eruption created 32 new volcanoes with a stretch of 18 km. You know, everything that appears black is lava !
Mt. Bromo is a small but extremely popular and active volcano on Java, Indonesia. It lies in a huge caldera which is visible if you zoom out a bit. There are 2 more semi-dormant volcanoes in the caldera
Wolf, the highest volcano of the Galápagos Islands, straddles the equator at the north end of the archipelago's largest island, Isabela. The 1710-m-high Volcán Wolf has steeper slopes than most other Isabela volcanoes, reaching angles up to 35 degrees. A 6 x 7 km caldera, at 700 m one of the deepest of the Galápagos Islands, is located at the volcano's summit. A prominent bench on the west side...
