Abstract
-
The explosive January 2022 Hunga submarine eruption in Tonga injected
unprecedented water volumes into the upper atmosphere, generating
widespread climatic impacts. However, it ejected anomalously little sulfur
compared with other eruptions of similar volume. We explain the missing
sulfur with volatile budgets calculated from volcanic ash samples spanning
the eruption. We show that magma was stored in a weakly stratified reservoir at
2.1 km to >5.6 km depth. Magma rose within <3 min and fragmented at 400?
1,000 m below sea level. This preserves microscale chemical mingling including
~1 wt% contrasts in magmatic water concentrations. The 11-h erup tion released
a total of 319 Tg of magmatic water, which is <10% of that derived from magmatic
seawater interaction. Comparing magmatic and residual glass sulfur concentrations
shows a total release of 9.4 TgS, but >93% of this entered the ocean
during submarine magma fragmentation. These results raise the concern that
satellite SO2 monitoring underestimates the magma output of submarine
explosions and they are probably near invisible in ice-core records, despite
their climate influence caused by water injection into the upper atmosphere.
