Volcanic Eruptions (E)

Several Earth-observing satellites have collected data during and after the powerful undersea volcanic eruptions that demolished a small, uninhabited South Pacific island known as Hunga Tonga-Hunga Ha‘apai. On 13th January, an unusually large blast rocked the volcano but an even larger explosion on the 15th of January produced an atmospheric shock wave and tsunami that travelled around the world.The eruptions generated an enormous cloud of ash, besides earthquakes and tsunamis that reached as far as the distant coastlines of Peru on the other side of the Pacific.
