Understanding explosion precursors: Investigating high-pressure defragmentation by laser ignition experiments
Highly explosive LLM-105 before and after laser-initiated burns inside diamond anvil cells. The sample mass is ~1 microgram. The product is opaque at low pressure and transparent at higher pressure (lower right panel). Note the increase and decrease in pressure, respectively.

Tonga’s volcanic eruption was caused by an explosion equivalent to ‘five underground nuclear bombs,’ new study reveals
Mr. Jinyin Hu and Dr. Thanh-Son Phạm. Credit: Jamie Kidston/ANU Two years on, new research from the Australian National University (ANU) has revealed the main trigger of one of the largest volcanic eruptions in history, the Hunga Tonga submarine volcano. The study is published in the journal Geophysical Research Letters. Until now, the cause of this disaster has remained a…
