Mauna Loa , Hawaii
Transcript of Mauna Loa , Hawaii
Mauna Loa is a shield volcano made by
repeated fluid lava flows that build a
very broad uplift.Gentle eruption style.
Hazards: Large earthquakes, Lava flows.
The principal hazards posed by Mauna Loa eruptions are its frequent, high-volume lava flows the long lengths of these flows , and lava fluidity (which results in high flow velocities especially on steep slopes). These flows pose serious risks to people living on lower slopes and to their property. Similar Volcanoes Mauna kea : Dorment Kohala : Extinct Past Eruptions 1843-1984 The 1984 eruption of Mauna Loa ended a 9-year period of quiescence. The eruption began suddenly, following a 3-year period of slowly increasing earthquake activity under the volcano that made a lot of earthquakes 5 to 13 km deep in mid-September 1983. Future Forecast It's been 25 years since Mauna Loa last erupted. Scientists can't predict when the Big Islands volcano will come to life again but they are prepared. Scientists want to use this anniversary to remind island residents that the world's biggest volcano is still active, and based on its past history, is overdue for another eruption.

Much of the mountain is below sea level the total height difference is 33,500 ft taller than Mount Everest . Mauna Kea is about two million years old, and thus passed the most active shield stage of life Kohala is the oldest of five volcanoes that make up the island of Hawaii . Kohala is estimated to be one million years old—so old that it experienced, and recorded, a reversal of magnetic field 780,000 years ago. It is believed to have breached sea level more than 500,000 years ago and to have last erupted 120,000 years ago. 39 Total eruptions
