Watching the volcano: The Kilauea eruption of 2018 was big on a global scale

Let’s start with what we know about the size of the 2018 eruption. Recent measurements by USGS researcher Hannah Dietrich and collaborators using digital elevation models and unoccupied aircraft systems produced an estimate of the volume of the lava flow for 2018. The higher estimate is 1.4 cubic kilometers (or about 0.34 cubic miles). The estimate has scope because it is difficult to measure the volume of lava flowing into the ocean.

To get a sense of the volume of lava for 2018, imagine a giant cube of lava sitting on the ground that is 0.7 miles high—or three times the height of the Empire State Building. For Hawaii residents, it’s about 27 times the height of Hilo’s Bayshore Towers.

It turns out that there have been only a few lava flow eruptions worldwide in the past few hundred years that have produced more than one cubic kilometer (0.24 cubic miles) of lava.

The largest in Hawaii in recent centuries was the Puʻu ʻOʻo eruption, which produced 4.4 cubic kilometers (1.1 cubic mi) of lava. However, this volcanic eruption lasted 35 years compared to four months after the LERZ 2018 eruption. The Puʻu ʻOʻo eruption destroyed 215 structures, compared to more than 700 destroyed in the 2018 eruption.

Other large-scale lava flows have occurred in Russia and Iceland. The eruption of Tolbachik in 1975-1976, in Kamchatka, Russia, lasted for a year and a half and produced about 2 cubic kilometers (0.48 cubic miles) of lava. In 2014-15, the six-month-long eruption of the Bararbunga volcano in Iceland resulted in a Holuhraun lava flow, about 1.4 cubic kilometers (0.34 cubic miles) in volume.

In both the Tolbachik and Bardarbunga eruptions, lava flows spurted out from the sides of the volcano and led to a subsidence at the summit as it drained the magma chamber, similar to what happened in 2018 at Kilauea. The eruptions of Tolbach and Bararbunga occurred in the hinterland, with no significant destruction of the populated areas.

An eruption of a volcano in the Canary Islands, Spain, also made the list. The eruption of Lanzarote in 1730–1736 produced 2 cubic kilometers (0.48 cubic mi) of lava and destroyed many villages on the side of the volcano.

The recent eruption of the Cumbre Vieja volcano, at La Palma in the Canary Islands, in 2021 was strongly impressive but we have not yet been able to find published volume estimates for the lava flow. Regardless of the size of the flow, the destruction was enormous, with around 3,000 buildings destroyed.

Another major eruption at Mexico’s Paricutin volcano occurred in 1943, when a fissure opened in a cornfield and the eruption lasted for 9 years, releasing 1.6 cubic kilometers (0.38 cubic miles) of lava.

However, none of these eruptions came close to the size and impact of the Laki eruption in Iceland in 1783. Over the course of eight months about 14.7 cubic kilometers (3.5 cubic miles) of lava covered the landscape, destroying dozens of villages. Volcanic gases poisoned livestock and destroyed crops, leading to a major famine in Iceland that claimed thousands of lives. It also affected the weather in Europe. Ben Franklin, the US ambassador who was living in France at the time, noticed how strange fog that summer might have come from Iceland’s volcano.

This giant cube of lava from Lucky will be 1.5 miles (2.4 kilometers) long.

There may be other lava flows larger than 1 cubic kilometer that we’ve lost in our rapid assembly here, but the fact remains that these are very rare events. We can see that the 2018 Kilauea lava flow was among the most important lava eruptions on Earth in recent centuries. The volcanic eruption was not only remarkable for its magnitude in Hawaii, but was also worldwide.

What are the results of compiling like this? Like earthquakes, most lava flows are small, and only a small portion are as massive as those listed here. But although these large pyroclastic flows are rare events, when they occur in populated areas, the effects can be devastating and long-lasting.

Volcano activity updates

Kilauea volcano erupts. USGS Volcano Alert Level in WATCH. Over the past week, lava has continued to erupt intermittently from the western vent within Halemaʻumaʻu crater. All the lava is trapped inside the Halemaʻumaʻu crater in Hawaii Volcanoes National Park. Emission rates of sulfur dioxide remain high and were last measured at around 1,400 tons per day (tons/day) on March 23 during declining volcanic activity.

Over the past week, lava has continued to erupt from the western vent within Halemaʻumaʻu crater. All of the lava is confined within the Halemaʻumaʻu crater in Hawai’i Volcanoes National Park. Sulfur dioxide emission rates remain high and was last measured at around 1,400 tons per day (tons/day) on 23 March 2022. Seismicity is high but stable, with few tremors and persistent volcanic tremors. Summit tilt gauges show relatively little deformation of the Earth over the past week.

Mauna Loa is not erupting and is still at the volcano alert level. This alert level does not mean that a volcano eruption is imminent or that progression to an eruption from the current level of disturbance is certain. Mauna Loa updates are released weekly.

Mauna Loa is not erupting and is still at the volcano alert level. In the past week, about 65 small earthquakes on the Richter scale were recorded below the summit and upper elevation sides of Mauna Loa – and most occurred at shallow depths less than 6 miles below sea level.

Six earthquakes were reported to have been felt in the Hawaiian Islands over the past week: a 3.4-magnitude earthquake 4 km (2 mi) southwest of Pahala at a depth of 36 km (22 mi) on March 29 at 8:23 p.m., a 3.7-magnitude earthquake; 8 km (4 mi) east of Pahala at a depth of 32 km (20 mi) on March 29 at 7:07 p.m. A 3.5-magnitude earthquake 26 km (16 mi) east of Hononau-Napopo at a depth of 0 km (0 mi) in March 29 3:19 a.m., 3.4 Richter scale earthquake 22 km (13 mi) northwest of Kalua at a depth of 46 km (28 mi) March 28 7:11 p.m. M3.3 earthquake 12 km (7 mi) )) southeast of Fern Forest at a depth of 6 km (4 mi) on March 26 at 10:10 a.m. A 3.1-magnitude earthquake occurred 4 km (2 mi) south of Pahala at a depth of 31 km (19 mi) at 25 March at 12:12 am
