1. Introduction The longest eruptive episode in recorded history for Kīlauea volcano on the island of Hawaii ended in early August 2018. Kīlauea’s recent episode was an effusive (nonexplosive) eruption that resulted in a continuous source of volcanic gas emissions for the 35 years since 1983. The eruption ended with eruptive fissures in Kīlauea’s lower east rift zone (LERZ). The LERZ eruption was an extreme event that had impacts on visibility as far away as the Mariana Islands, more than 6000

has been found to be approximately linearly related to global-mean surface temperature in many of the CMIP3 and CMIP5 models ( Gregory et al. 2002 ; Winton 2011 ; Mahlstein and Knutti 2012 ; Stroeve and Notz 2015 ), including over periods as brief as 1979–2013 (Rosenblum and Eisenman 2016). This implies that volcano-related biases in simulated global warming during recent decades should be associated with biases in sea ice retreat. Consistent with this, a number of studies have shown that

There is, however, a further unexplored possibility: that the heated summit of a volcano interacts with the orographic flow to force atmospheric convection and enhance precipitation, thus potentially

For the Fuego Volcano eruption case on 3 June 2018, ABI full-disk scans were available at 15-min intervals. For the Argentina severe thunderstorm case on 10 November 2018, a special ABI mesoscale sector provided imagery every 60 s. This location was otherwise seen at 15-min intervals by the ABI full-disk scans. The ABI scan mode was subsequently changed to

A program to measure and forecast the dispersion of hazardous volcanic emissions from the Kīlauea volcano in Hawaii is described. In 2014, Kīlauea volcano on the island of Hawaii entered its 32nd year of nearly continuous eruption. The current activity began in January 1983 and the first 4 years of the eruption included sensational episodes of lava fountains. During the high-fountaining events, sulfur dioxide (SO 2 ) emissions from Kīlauea’s east rift zone ranged from 5,000 to 30,000 tonnes of

1. Introduction Axial Volcano, sitting astride the Juan de Fuca Ridge and above the Cobb Hotspot ( Karsten and Delaney 1989 ; Desonie and Duncan 1990 ) at 45°58′N, 130°W, erupted lava onto the seafloor in January 1998 ( Dziak and Fox 1999 ; Embley et al. 1999 ). Prior to the eruption, the caldera of the volcano had seen extensive surveys that located a number of focused- and diffuse-source hydrothermal venting sites (e.g., Baker et al. 1990 ; Embley et al. 1990 ). Following the eruption

Catastrophic events such as volcano explosions ( Choi et al. 2003 ) or asteroid impacts ( Chapman and Morrison 1994 ; Morgan et al. 2022 ) are known to cause extreme damage near their epicenters but also to affect the entire planet through megatsunamis ( Kharif and Pelinovsky 2005 ), acidification of the atmosphere and ocean ( Ohno et al. 2014 ), aerosol-driven reduction of solar radiation ( Kring et al. 1996 ), and many other planetary-scale processes. However, the global impact of
