Rumor here in Rhode Island is that a cigarette was being extinguished in the beach sand. (The women was known to have been smoking earlier in the day.) So that's one potential ignition source. Here is a link to a pdf of a short power point with more chemistry and good photos of the suspicious cable. (I haven't been able to locate the actual report)

Now, back to the beach!!

BUILT UP GAS LIKELY CAUSED MYSTERIOUS R.I. BEACH EXPLOSION
Tags: us_RI, public, follow-up, injury, hydrogen
Question: How does sand, seawater, copper, and goo produce enough hydrogen to create an explosion? What is the normal concentration of hydrogen one might expect to find in a sandy beach? The LEL and HEL for hydrogen are 4.0 and 45.0 %. Then, there is always the need for an ignition source. Interesting problem!
