Hi Lauren! Thanks for letting us know about this --yep, you're right -- does look like an error that we need to fix! We hope to have that working again soon. (and we are also working on an API for lots of our data, including the geochem!) Thanks, cheryl Hello. I've been getting an error message when using your 'Explore data' eruption search and I wasn't sure who to contact about it! When I try to use a 'Descriptions' choice (any of the listed options - I've tested several), I get the following error: SQLSTATE[HY093]: Invalid parameter number: parameter was not defined. This doesn't occur when I search with just start and end dates but not a description choice. Thanks, Lauren
