“…The FRESH database contains the first dated Holocene eruption from 865 active volcanoes (Burgos et al 2022). The data in the FRESH database was extracted from the VOTW database (v. 4.7.5, 21 December 2018).…”

“…The oldest FRESH was at Igwisi Hills (Tanzania) in 10,450 before current era (BCE), and the most recent was at Mariana Back-Arc Segment at 15.5° N (the USA) in 2013 current era (CE). This database, which can be downloaded from the supplementary material in Burgos et al (2022), includes details from each FRESH (e.g., eruption start date and size) alongside characteristics of each volcano (e.g., major rock composition and region). We followed the new regional delimitation proposed by Burgos et al (2022), in which each region contains only subregions with similar degrees of data completeness.…”

“…Unfortunately, unexpected eruptions from potentially active volcanoes are not rare. According to Burgos et al (2022), 101 volcanoes have had their first dated Holocene eruption since the beginning of the twentieth century, with nearly 20% of them being a VEI ≥ 3 (Fig. 1).…”

“…An important step towards expanding our knowledge on potentially active volcanoes is establishing how often potentially active volcanoes erupt regionally. To do so, we used the First Recorded EruptionS in the Holocene (FRESH) database from Burgos et al (2022), which contains the first dated Holocene eruption from each volcano in the VOTW database. For this work, we further compiled a database of potentially active volcanoes from the (GVP 2013), Whelley et al (2015), and Taisne et al (2017).…”

Since the start of the twentieth century, 101 potentially active volcanoes have produced their first Holocene eruption, as recorded in the volcanoes of the world (VOTW) database. The reactivation of potentially active volcanoes is often a surprise, since they tend to be less well-studied and unmonitored. The first step towards preparing for these unexpected eruptions is to establish how often potentially active volcanoes have erupted in the past. Here, we use our previously developed FRESH (First Recorded EruptionS in the Holocene) database to estimate the past regional Average Recurrence Interval (ARI) of these unexpected events. Within the most complete portions of the FRESH database, a FRESH (i.e., the first recorded eruption from a potentially active volcano) has occurred as frequently as every ~ 7 years in the Pacific Ocean region (~ 50 years of relatively complete record) and ~ 8 years in Izu, Volcano, and the Mariana Islands region (~ 150 years of relatively complete record). We use the regional frequency to estimate the annual probability of a FRESH at individual potentially active volcanoes in selected regions of Asia–Pacific, which ranged from 0.003 for Izu, Volcano, and Mariana Islands to 1.35 × 10−5 for Luzon. Population exposure around potentially active volcanoes showed that at volcanoes such as Kendeng (Indonesia) and Laguna Caldera (Philippines), more than 30 million people reside within 100 km of the summit. With this work, we hope to establish how often potentially active volcanoes erupt, while identifying which regions and which potentially active volcanoes may require more attention.

The recent destruction of thousands of homes by lava flows from La Palma volcano, Canary Islands, and Nyiragongo volcano, Democratic Republic of Congo, serves as a reminder of the devastating impact that lava flows can have on communities living in volcanically active regions. Damage to buildings and infrastructure can have widespread and long-lasting effects on rehabilitation and livelihoods. Our understanding of how lava flows interact with buildings is limited and based upon sparse empirical data. Often a binary impact is assumed (destroyed when in contact with the flow and intact when not in contact with the flow), although previous events have shown this to be an oversimplification. Empirical damage data collected after past events provide an evidence base from which to better understand lava flow impacts across a range of building types, environments, and eruption styles, as well as to explore the temporal and spatial trends in these impacts. However, information on lava flow impacts is scattered across literature, reports, and maps; no comprehensive dataset of lava flow impacts exists. In this study, we compile and standardise lava flow impact information from previously compiled data, eruption records, and published literature to create the first comprehensive global dataset of impacts on the built environment from lava flows. We found that since the first recorded event between 5494 yr B.P. and 5387 yr B.P., lava flows from at least 155 events have impacted buildings or infrastructure (e.g., roads, electricity pylons, ski-lifts), with most (47%, n = 73) recorded as located in Europe. Over the last century, there have been approximately seven lava flow impact events per decade (n = 71 total). This greatly expands on the past compilations of lava flow impact events. Since ca. 1800 CE, impacts have been consistently documented for less than 14% of recorded eruptions with lava flows globally; prior to 1800 CE, impacts were recorded much more variably (between 0 and 70% of lava flows in any 10-year time bin). The most destructive recorded events were the 1669 CE lava flows at Etna volcano, Italy, which destroyed up to 12 villages and part of the city of Catania, and the 2002 CE lava flows at Nyiragongo volcano, Democratic Republic of Congo, which destroyed up to 14,000 buildings. We found that few studies in the dataset report building typology, damage severity, or hazard intensity at the building-level scale, limiting our ability to assess past building-lava interactions. Future collection of building-level hazard and impact data, supplemented with non-English language records, can be used to inform models that forecast future impacts, support lava flow risk assessments, and develop potential mitigation measures.

The recent destruction of thousands of homes by lava flows from Cumbre Vieja, La Palma, Spain and Nyiragongo volcano, Democratic Republic of Congo, serves as a reminder of the devastating impact that lava flows can have on communities living in volcanically active regions. Damage to buildings and infrastructure in particular can have widespread and long-lasting effects on rehabilitation and livelihoods. Our understanding of how lava flows interact with buildings is limited and based upon sparse empirical data. Often a binary impact is assumed (lava flows destroy buildings), although previous events have shown this to be an oversimplification. Empirical damage data collected after past events can provide an evidence base from which to better understand lava flow impacts across a range of building types, environments and eruption styles, as well as temporal and spatial trends. However, information on lava flow impacts is scattered across literature, reports and maps; no comprehensive dataset of lava flow impacts exists. In this study, we review, compile and standardise lava flow impact information in published literature to create the first comprehensive global dataset of lava flow events with impacts on the built environment. We found that since the first recorded event between 5494 year B.P. and 5387 year B.P., lava flows from at least 127 eruptions impacted buildings or infrastructure, with the most (34%; n = 43) located in Europe. There are almost six lava flow impact events per decade, with 57 events occurring in the past 100 years (or 39 events without infrastructure-only impacts). This greatly expands on the past estimate of lava flow impact frequency of two events per decade. Impacts from lava flows are documented in less than 10% of recorded lava flows globally, with this remaining constant since ∼1800 CE; prior to 1800 CE, impacts were recorded much more variably representing between 0 and 35% of lava flows in any 10 year time bin. The most destructive recorded events were the 1669 CE lava flows at Etna volcano, Italy, which destroyed up to 12 villages and part of the city of Catania, and the 2002 CE lava flows at Nyiragongo volcano, Democratic Republic of Congo which destroyed at least 4,500 buildings. We found that few studies in the dataset report building typology, damage severity, hazard intensity, or damage at the structure-level scale, limiting our ability to assess past building-lava interactions. Future collection of structure-level hazard and impact data can be used to inform models to forecast future impacts, support lava flow risk assessments and develop potential mitigation measures.
