Lava Flows facts
While investigating facts about Lava Flows Hawaii and Lava Flows Drink, I found out little known, but curios details like:
In 1973, a volcano erupted on the Icelandic island of Heimaey. Rather than fleeing to safety, the residents of the island sprayed the advancing lava flow with seawater in order to form a wall and direct the lava into the sea.
how lava flows are generated by volcanoes?
In 1935 the U.S. 23rd Bomb Squadron dropped twenty 600-pound bombs in the path of a volcano’s lava flow, thus saving the city of Hilo, Hawaii by diverting the lava away from the city.
What lava flows are found on the moon?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what are lava flows. Here are 44 of the best facts about Lava Flows Big Island and Lava Flows Definition I managed to collect.
why is damage limited at lava flows?
-
In 1973, Icelanders successfully stopped a lava flow that threatened their town by spraying it with seawater
-
In the southern region of the park the landscape consists of montane tropical forests, alpine forests, and it has old and new lava flows.
-
5 days after the volcano had grown and erupted, lava began flowing from the vent of the volcano onto the surrounding land.
-
The active volcanoes in Hawaii Volcanoes National Park continue to resurface the land because the lava continues to flow. This results in a constantly changing environment.
-
An exception to the slow moving lava is the stratovolcano Mount Nyiragongo which has fast moving lava. The steep slopes of the volcano and the fluid lava make it possible for the lava to flow as fast as 62 miles per hour down the mountainside.
-
There are also Colorado River Flood Basalts, which are an extensive sequence of layers of lava flow reaching a thickness of up to 6,000 feet.
-
Since 1970, if you own land on the coast of Hawai`i that is expanded by lava flow, the public owns the new extension
-
Kingdom of Saudi Arabia has volcanoes. "The last well-documented eruption in Saudi Arabia occurred in the northern end of Harrat Rahat near Al Madinah in 1256 AD / 654 AH . . . continued for 52 days, and the lava flow reached to within 12 km [7.4565 miles] of the city before activity ceased."
-
In 2014 Kilauea's lava flow threatened to destroy the Hawaiian town Pahoa, but the flow stopped short of the town and by 2015 the threat appeared to be greatly reduced.
-
In 1977 the Hawaii Supreme Court ruled that the term "high water mark" doesn't necessarily refer to the high water mark on a shore, and a lava flow that extended one's property into the ocean was an unfair windfall so all land created by lava belonged to the state.
Lava Flows data charts

When and why did lava flows end?
You can easily fact check how are lava flows hazards by examining the linked well-known sources.
The last eruption of Mauna Loa in 1984 resulted in lava flow that stretched as far 4.5 miles of Hilo. This eruption lasted from March 25th to April 15th.
Shield volcanoes" low viscosity lava means that the lava is more liquid and flows more quickly than thick lava. Therefore it can spread further, building up thin layers that continue to accumulate and create the shield volcano's shape.
Basalt is also an abundant rock found on the Moon with much of its surface underlain by basaltic lava flows and flood basalts as well, with the areas known as "lunar maria."
In 1935 when Hawaii's Mauna Loa volcano erupted and threatened the town of Hilo, the US Army Air Corps attempted to divert the oncoming lava flows with bombing runs planned by George S. Patton (then a Lt.Col.)
The temperature of the lava flow was is 1,958oF (1,070oC), moving at a speed of 196 feet/minute (60 meters /minute).
When lava flows reach the ocean they?
In 1986, a lava flow from a volcano entered Lake Nyos in Cameroon & released a large cloud of CO2, which suffocated 1,746 people in nearby villages.
How lava flows are formed?
Olympus mons, a shield volcano on Mars, was formed from basaltic lava flows. It is the largest known volcano in the solar system and the highest mountain on Mars.
Fresh ground water flows through lava tubes, on some of the Hawaiian islands, and flows into the sea creating offshore freshwater springs. Fishermen of old knew how to spot such springs and could draw fresh water into their boats from them. (Addition sources linked in comments)
Rhyolite will often appear very uniform in texture, although lava flow structures may be evident.
When lavas pick up rock fragments, they can form volcanic breccia, also referred to as pillow breccias. When the crust of a lava flow is broken up during movement, it is called flow breccia.
The source of the rock's name, andesite, comes from the Andes Mountains of South America as lava flows mixed in with ash and tuff deposits on the flanks of stratovolcanoes.
