Some volcanoes are perfect cone … On the other hand, vent discharges were limited to ash-filled plumes with volcanic lightning propelled into the sky at velocities more than 123 miles per second (55 meters per second). In this respect the Auckland volcanic field is different from volcanoes such as Mount Egmont or Mount Ruapehu where eruptions can be expected from the present crater. It consists of an elongated ice-covered stratovolcano with a 2.5-km-wide summit caldera. However, generalised hazard zones can be estimated in advance and can be superimposed onto a map once the likely eruption site has been determined by the monitoring network. Fissure-fed lava flows occur on both the E and W flanks, but are more prominent on the western side. A way to monitor these vent discharges, as the case with Sakurajima, could help scientists spot volcanic eruptions that contains a lot of ashes. One way scientists can anticipate that a volcano will blow its top is by using seismology. This book sets these impressive phenomena in their world context and explains their formations and effects, focusing especially on the many styles of eruptions and the multitude of volcanic landscape forms that result. Each volcano and situation is unique. As one of its most active volcanoes, a former island connected to the neighboring peninsula after its lava flowed in 1914 hardened and became land. During the season, it is common for the nights to be warm, especially when winds are from the southeast or south.
