when did mount vesuvius erupt for the first time
Mount Vesuvius Mount Vesuvius is best known for its eruption in AD 79 that led to the burying and destruction of the Roman cities of Pompeii and Herculaneum, as well as several other settlements. The eruption ejected a cloud of stones, ashes and volcanic gases to a height of 33 km (21 mi), spewing molten rock and pulverized pumice at the rate of 6×105 cubic metres (7.8×105 cu yd) per second,[2] ultimately releasing a hundred thousand times the thermal energy released by the Hiroshima-Nagasaki bombings.[3] More than 1,000 people died in the eruption, but exact numbers are unknown. The only surviving eyewitness account of the event consists of two letters by Pliny the Younger to the historian Tacitus.[4]
Mount Pinatubo On March 15, 1991, a succession of earthquakes was felt by villagers on the northwestern side of the volcano. Further earthquakes of increasing intensity were felt over the next two weeks, and it became clear some kind of volcanic activity was likely. On April 2, the volcano awoke, with phreatic eruptions occurring near the summit along a 1.5 km (0.93 mi) long fissure. Over the next few weeks, small eruptions continued, dusting the surrounding areas with volcanic ash. Seismographs recorded hundreds of small earthquakes every day.

Kīlauea Geologists have dated and documented dozens of major eruptions over the volcano's long history, bridging the long gap between Kīlauea's oldest known rock and only extremely recent written records and historical observation.[31] Historical lava flows from the volcano are generally recovered by scientists in one of three ways. The oldest flows, dating back 275,000 to 225,000 years, have been recovered from Kīlauea's submerged southern slope by ship-towed remotely operated vehicles. These lavas exhibit forms characteristic of early, submerged preshield-stage eruptive episodes, from when the volcano was still a rising seamount that had not yet breached the ocean surface,[32] and their surface exposure is unusual, as in most other volcanoes such lavas would have since been buried by more recent flows.[12]
